It has ability to enhance percutaneous penetration by loosening the dense of the compact substance stratum corneum. The aim of this research was to observe the effects of NaHA on caffeine penetration as anticellulite active agent in three types of gel preparation: hydrogel, hydroalcoholic gel, and gel emulsion. Each gel type contained caffeine 1,5% and was varied into three formulas. Formula 1 contained HPMC 2% as gel basis; …

Mechanism Underlying Ikk Activation Mediated By The Linear Ubiquitin Chain Assembly Complex (Lubac), Hiroaki Fujita, Simin Rahighi, Mariko Akita, Ryuichi Kato, Yoshiteru Sasaki, Soichi Wakatsuki, Kazuhiro Iwai

Pharmacy Faculty Articles and Research

The linear ubiquitin chain assembly complex (LUBAC) ligase, consisting of HOIL-1L, HOIP, and SHARPIN, specifically generates linear polyubiquitin chains. LUBAC-mediated linear polyubiquitination has been implicated in NF-κB activation. NEMO, a component of the IκB kinase (IKK) complex, is a substrate of LUBAC, but the precise molecular mechanism underlying linear chain-mediated NF-κB activation has not been fully elucidated. Here, we demonstrate that linearly polyubiquitinated NEMO activates IKK more potently than unanchored linear chains. In mutational analyses based on the crystal structure of the complex between the HOIP NZF1 and NEMO CC2-LZ domains, which are involved in the HOIP-NEMO interaction, NEMO mutations …

Campbell, Shaun P. Lynch, James W. Denham, Angela V. Hanley, Kenny W. Bullins, Peter C. Panus, Krishna Singh, Sam Harirforoosh

Pharmacy Faculty Articles and Research

Nonsteroidal anti-inflammatory drugs (NSAIDs) can produce adverse effects by inhibiting prostaglandin (PG) synthesis. A PGE1 analogue, misoprostol, is often utilized to alleviate NSAID-related gastrointestinal side effects. This study examined the effect of misoprostol on celecoxib renal toxicity. Additionally, the effects of these drugs on cardiovascular parameters were evaluated. Four randomized rat groups were orally gavaged for 9 days, two groups receiving vehicle and two groups receiving misoprostol (100 µg/kg) twice daily. Celecoxib (40 mg/kg) was co-administered once daily to one vehicle and one misoprostol group from days 3 to 9. Urine and blood samples were collected and blood pressure parameters …

Design And Optimization Of Plga-Based Diclofenac Loaded Nanoparticles, Dustin L. Cooper, Sam Harirforoosh

Pharmacy Faculty Articles and Research

Drug based nanoparticle (NP) formulations have gained considerable attention over the past decade for their use in various drug formulations. NPs have been shown to increase bioavailability, decrease side effects of highly toxic drugs, and prolong drug release. Nonsteroidal anti-inflammatory drugs such as diclofenac block cyclooxygenase expression and reduce prostaglandin synthesis, which can lead to several side effects such as gastrointestinal bleeding and renal insufficiency. The aim of this study was to formulate and characterize diclofenac entrapped poly(lactide-co-glycolide) (PLGA) based nanoparticles. Nanoparticles were formulated using an emulsion-diffusion-evaporation technique with varying concentrations of poly vinyl alcohol (PVA) (0.1, 0.25, 0.5, or …

Adverse Effects Of Nonsteroidal Anti-Inflammatory Drugs: An Update Of Gastrointestinal, Cardiovascular, And Renal Complications, Sam Harirforoosh, Waheed Asghar, Fakhreddin Jamali

Pharmacy Faculty Articles and Research

Non-steroidal anti-inflammatory drugs (NSAIDs) are used chronically to reduce pain and inflammation in patients with arthritic conditions, and also acutely as analgesics by many patients. Both therapeutic and adverse effects of NSAIDs are due to inhibition of cyclooxygenase (COX) enzyme. NSAIDs are classified as non-selective and COX-2-selective inhibitors (COXIBS) based on their extent of selectivity for COX inhibition. However, regardless of their COX selectivity, reports are still appearing on the GI side effect of NSAIDs particularly on the lower gastrointestinal (GI) tract and the harmful role of their controlled release formulations. In addition, previously unpublished data stored in the sponsor’s …

Cxcr7 Expression Disrupts Endothelial Cell Homeostasis And Causes Ligand-Dependent Invasion, Jennifer Totonchy, Lisa Clepper, Kevin G. Phillips, Owen J. T. Mccarty, Ashlee V. Moses

Pharmacy Faculty Articles and Research

The homeostatic function of endothelial cells (EC ) is critical for a number of physiological processes including vascular integrity, immunity, and wound healing. Indeed, vascular abnormalities resulting from EC dysfunction contribute to the development and spread of malignancies. The alternative SDF-1/CXCL12 receptor CXCR7 is frequently and specifically highly expressed in tumor-associated vessels. In this study, we investigate whether CXCR7 contributes to vascular dysfunction by specifically examining the effect of CXCR7 expression on EC barrier function and motility. We demonstrate that CXCR7 expression in EC results in redistribution of CD31/PECAM-1 and loss of contact inhibition. Moreover, CXCR7+ EC are deficient in …

Non-Raft Ac2 Defines A Camp Signaling Compartment That Selectively Regulates Il-6 Expression In Airway Smooth Muscle Cells, Amy S. Bogard, Anna V. Birg, Rennolds S. Ostrom

Pharmacy Faculty Articles and Research

Adenylyl cyclase (AC) isoforms differ in their tissue distribution, cellular localization, regulation, and protein interactions. Most cell types express multiple AC isoforms. We hypothesized that cAMP produced by different AC isoforms regulates unique cellular responses in human bronchial smooth muscle cells (BSMC). Overexpression of AC2, AC3, or AC6 had distinct effects on forskolin (Fsk)-induced expression of a number of known cAMP-responsive genes. These data show that different AC isoforms can differentially regulate gene expression. Most notable, overexpression and activation of AC2 enhanced interleukin 6 (IL-6) expression, but overexpression of AC3 or AC6 had no effect. IL-6 production by BSMC was …

Beyond Peroxisome: Abcd2 Modifies Pparα Signaling And Identifies A Subclass Of Peroxisomes In Mouse Adipose Tissue, Xiaoxi Liu

Theses and Dissertations--Pharmacy

ABCD2 (D2) has been proposed as a peroxisomal long-chain acyl-CoA transporter that is essential for very long chain fatty acid metabolism. In the livers of mice, D2 is highly induced by fenofibrate, a PPARα ligand that has been widely used as a lipid lowering agent in the treatment of hypertriglyceridemia. To determine if D2 is a modifier of fibrate responses, wild-type and D2 deficient mice were treated with fenofibrate for 14 days. The absence of D2 altered expression of gene clusters associated with lipid metabolism, including PPARα signaling. Using 3T3-L1 adipocytes, which express high levels of D2, we confirmed that …

Lobelane Analogs With Various Methylene Linker Lengths And Acyclic Lobelane Analogs As Potential Pharmacotherapies To Treat Methamphetamine Abuse, Zheng Cao

Theses and Dissertations--Pharmacy

Methamphetamine interacts with vesicular monoamine transporter-2 (VMAT2) to inhibit dopamine (DA) uptake and promotes DA release from presynaptic vesicles, increasing cytosolic DA available for methamphetamine-induced reverse transport by DA transporters. By inhibiting VMAT2, lobelane, a defunctionalized, saturated lobeline analog, decreases methamphetamine-evoked DA release and methamphetamine self-administration in rats. In this dissertation structure-activity relationships around the lobelane structure were investigated on racemic lobelane analogs with varying methylene linker lengths at central piperidine ring. Affinity for dihydrotetrabenazine (DTBZ) sites on VMAT2 and for inhibition of VMAT2 function was determined to be 0.88-63 and 0.024-4.6 µM, respectively, and positively correlated. The most potent …

Phosphatidylinositol 3-Kinase (Pi3k) As A Therapeutic Target In Nsclc, Christopher W. Stamatkin

Theses and Dissertations--Pharmacy

Deregulated activation of phosphatidylinositol 3-kinase (PI3K) pathway is central to many human malignancies. The functions of this pathway are critical for normal cell metabolism, proliferation, and survival. In lung cancers, the PI3K pathway activity is often aberrantly driven by multiple mutations, including EGFR, KRAS, and PIK3CA. Molecules targeting the PI3K pathway are intensely investigated as potential anti-cancer agents. Although inhibitors of the pathway are currently in clinical trials, rational and targeted use of these compounds, alone or in combination, requires an understanding of isoform-specific activity in context. We sought to identify class IA PI3K enzyme (p110a/PIK3CA, p110b/PIK3CB, p110d/PIK3CD) activities using …

Simultaneous Bactericidal And Osteogenic Effect Of Nanoparticulate Calcium Phosphate Powders Loaded With Clindamycin On Osteoblasts Infected With Staphylococcus Aureus, Vuk Uskoković, Tejal A. Dasai

Pharmacy Faculty Articles and Research

S aureus internalized by bone cells and shielded from the immune system provides a reservoir of bacteria in recurring osteomyelitis. Its targeting by the antibiotic therapy may thus be more relevant for treating chronic bone infection than eliminating only the pathogens colonizing the bone matrix. Assessed was the combined osteogenic and antibacterial effect of clindamycinloaded calcium phosphate nanoparticles of different monophasic compositions on co-cultures comprising osteoblasts infected with S aureus. Antibiotic-carrying particles were internalized by osteoblasts and minimized the concentration of intracellular bacteria. In vitro treatments of the infected cells, however, could not prevent cell necrosis due to the …

Areas covered—Shortcomings of the clinically available treatment options, including poly(methyl methacrylate) beads and calcium sulfate cements, are discussed and their transcending using calcium-phosphate/polymeric nanoparticulate composites is foreseen. Bone is a composite wherein the weakness of each component alone is …

Evaluation Of The Allometric Exponents In Prediction Of Human Drug Clearance, Da Zhang

Theses and Dissertations

Background. Allometric scaling (AS) is widely used in predicting human clearance (CL) based on animal data. Substantial prediction errors have been commonly observed and various modifications to AS have not provided a broad reliable improvement. In this study, an extensive data set was assembled including animal and human systemic CL and physiochemical properties. The allometric exponents were calculated based on multiple species AS and single-species AS methods. The correlations between the allometic exponents and physiochemical properties were evaluated in an attempt to find covariates that may explain the inter-compound variability in the allometric exponents. Lastly, the statistical approaches in analyzing …

In Vitro Analysis Of Nanoparticulate Hydroxyapatite/Chitosan Composites As Potential Drug Delivery Platforms For The Sustained Release Of Antibiotics In The Treatment Of Osteomyelitis, Vuk Uskoković, Tejal A. Dasai

Pharmacy Faculty Articles and Research

Nanoparticulate composites of hydroxyapatite (HAp) and chitosan were synthesized by ultrasound-assisted sequential precipitation and characterized for their microstructure at the atomic scale, surface charge, drug release properties, and combined antibacterial and osteogenic response. Crystallinity of HAp nanoparticles was reduced because of the interference of the surface layers of chitosan with the dissolution/reprecipitation-mediated recrystallization mechanism that conditions the transition from the as-precipitated amorphous calcium phosphate phase to the most thermodynamically stable one—HAp. Embedment of 5–10 nm sized, narrowly dispersed HAp nanoparticles within the polymeric matrix mitigated the burst release of the small molecule model drug, fluorescein, bound to HAp by physisorption, …

Microbicidal Effects Of Α- And Θ-Defensins Against Antibiotic-Resistant Staphylococcus Aureus And Pseudomonas Aeruginosa, Kenneth P. Tai, Karishma Kamdar, Jason Yamaki, Valerie V. Le, Dat Tran, Patti Tran, Michael E. Selsted, Andre J. Ouelette, Annie Wong-Beringer

Pharmacy Faculty Articles and Research

Antibiotic-resistant bacterial pathogens threaten public health. Because many antibiotics target specific bacterial enzymes or reactions, corresponding genes may mutate under selection and lead to antibiotic resistance. Accordingly, antimicrobials that selectively target overall microbial cell integrity may offer alternative approaches to therapeutic design. Naturally occurring mammalian α- and θ-defensins are potent, non-toxic microbicides that may be useful for treating infections by antibiotic-resistant pathogens because certain defensin peptides disrupt bacterial, but not mammalian, cell membranes. To test this concept, clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA), including vancomycin heteroresistant strains, and ciprofloxacin-resistant Pseudomonas aeruginosa (Cip^R-PA) were tested for sensitivity to …

Effects Of Short-Term Portacaval Anastomosis On The Peripheral And Brain Disposition Of The Blood-Brain Barrier Permeability Marker Sodium Fluorescein In Rats, Imam H. Shaik, M. K. Miah, Ulrich Bickel, Reza Mehvar

Pharmacy Faculty Articles and Research

Contradictory results have been reported with regard to the effects of various models of hepatic encephalopathy on the blood-brain barrier (BBB) permeability, which may be due partly to the use of brain concentrations of BBB markers without attention to their peripheral pharmacokinetics. The purpose of the current study was to investigate the effects of short-term portacaval anastomosis (PCA), a type B model of hepatic encephalopathy, on the peripheral pharmacokinetics and brain distribution of sodium fluorescein (FL), which is a small molecule marker of BBB passive permeability. A single 25 mg/kg dose of FL was administered intravenously to 10-day PCA and …

Aryl Hydrocarbon Receptor Ligands Inhibit Igf-Ii And Adipokine Stimulated Breast Cancer Cell Proliferation, Travis B. Salisbury, Gary Z. Morris, Justin K. Tomblin, Ateeq R. Chaudhry, Carla Cook, Nalini Santanam

Pharmaceutical Science and Research

Obesity increases human cancer risk and the risk for cancer recurrence. Adipocytes secrete paracrine factors termed adipokines that stimulate signaling in cancer cells that induce proliferation. The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that plays roles in tumorigenesis, is regulated by exogenous lipophilic chemicals, and has been explored as a therapeutic target for cancer therapy. Whether exogenous AHR ligands modulate adipokine stimulated breast cancer cell proliferation has not been investigated. We provide evidence that adipocytes secrete insulin-like growth factor 2 (IGF-2) at levels that stimulate the proliferation of human estrogen receptor (ER) positive breast cancer cells. Using …

Computational And Experimental Insights Into The Mechanism Of Substrate Recognition And Feedback Inhibition Of Protoporphyrinogen Oxidase, Ge-Fei Hao, Ying Tan, Sheng-Gang Yang, Zhi-Fang Wang, Chang-Guo Zhan, Zhen Xi, Guang-Fu Yang

Pharmaceutical Sciences Faculty Publications

Protoporphyrinogen IX oxidase (PPO; EC 1.3.3.4) is an essential enzyme catalyzing the last common step in the pathway leading to heme and chlorophyll biosynthesis. Great interest in PPO inhibitors arises from both its significance to agriculture and medicine. However, the discovery of PPO inhibitors with ultrahigh potency and selectivity is hampered due to lack of structural and mechanistic understanding about the substrate recognition, which remains a longstanding question central in porphyrin biology. To understand the mechanism, a novel binding model of protogen (protoporphyrinogen IX, the substrate) was developed through extensive computational simulations. Subsequently, amino acid residues that are critical for …

Tigecycline Induction Of Phenol-Soluble Modulins By Invasive Methicillin-Resistant Staphylococcus Aureus Strains, Jason Yamaki, Timothy Synold, Annie Wong-Beringer

Pharmacy Faculty Articles and Research

We examined the effects of tigecycline on three types of exoproteins, α-type phenol-soluble modulins (PSMα1 to PSMα4), α-hemolysin, and protein A, in 13 methicillin-resistant Staphylococcus aureus isolates compared to those of clindamycin and linezolid. Paradoxical increases in PSMαs occurred in 77% of the isolates with tigecycline at 1/4 and 1/8 MICs and clindamycin at 1/8 MIC compared to only 23% of the isolates with linezolid at 1/8 MIC. Induction was specific to PSMα₁ to PSMα₄, as protein A and α-hemolysin production was decreased under the same conditions by all of the antibiotics used.

Design, Synthesis And Evaluation Of Antimicrobial Activity Of N-Terminal Modified Leucocin A Analogues, Krishna Chaitanya Bodapati, Rania Soudy, Hashem Etayash, Michael Stiles, Kamaljit Kaur

Pharmacy Faculty Articles and Research

Class IIa bacteriocins are potent antimicrobial peptides produced by lactic acid bacteria to destroy competing microorganisms. The N-terminal domain of these peptides consists of a conserved YGNGV sequence and a disulphide bond. The YGNGV motif is essential for activity, whereas, the two cysteines involved in the disulphide bond can be replaced with hydrophobic residues. The C-terminal region has variable sequences, and folds into a conserved amphipathic α-helical structure. To elucidate the structure–activity relationship in the N-terminal domain of these peptides, three analogues (1–3) of a class IIa bacteriocin, Leucocin A (LeuA), were designed and synthesized by …

We Can Do More Than Just Sell The Test: Pharmacist Perspectives About Over-The-Counter Rapid Hiv Tests, Beth Meyerson, Priscilla T. Ryder, Christiana Van Hippel, Kelsey Coy

Scholarship and Professional Work – COPHS

Pharmacist attitudes about the over-the-counter (OTC) sale of HIV rapid tests in pharmacies were explored through interviews conducted among 17 licensed community pharmacists in a Midwestern, moderate HIV incidence state between May and September 2012. Participants recognized that OTC rapid HIV tests would increase the number of people aware of their HIV status. Concerns included linkage to care and results consultation for those who test HIV-positive. Point of sale was identified as an opportunity for consultation about the test and to establish a relationship for future discussion about results and linkage to care. Pharmacists could provide initial test consultation or …
