Pharmacy Faculty Articles and Research

Small interfering RNA (siRNA) therapy is a promising approach for treatment of a wide range of cancers, including breast cancers that display variable phenotypic features. To explore the general utility of siRNA therapy to control aberrant expression of genes in breast cancer, we conducted a detailed analysis of siRNA delivery and silencing response in vitro in 6 separate breast cancer cell models (MDA-MB-231, MDA-MB-231-KRas-CRM, MCF-7, AU565, MDA-MB-435 and MDA-MB-468 cells). Using lipopolymers for siRNA complexation and delivery, we found a large variation in siRNA delivery efficiency depending on the specific lipopolymer used for siRNA complexation and delivery. Some lipopolymers were …

The non-genomic mechanisms by which glucocorticoids modulate β₂ agonist-induced-bronchodilation remain elusive. Our studies aimed to elucidate mechanisms mediating the beneficial effects of glucocorticoids on agonist-induced bronchodilation. Utilizing human precision cut lung slices (hPCLS), we measured bronchodilation to formoterol, prostaglandin E₂ (PGE₂), cholera toxin (CTX) or forskolin in the presence and absence of budesonide. Using cultured human airway smooth muscle (HASM), intracellular cAMP was measured in live cells following exposure to formoterol, PGE₂, or forskolin in the presence or absence of budesonide. We showed that simultaneous budesonide administration amplified formoterol-induced bronchodilation and attenuated agonist-induced phosphorylation …

Systemic Toxicity Reported For Cdk8/19 Inhibitors Cct251921 And Msc2530818 Is Not Due To Target Inhibition, Mengqian Chen, Jing Li, Jiaxin Liang, Zanshé S. Thompson, Katie Kathrein, Eugenia Broude, Igor Roninson

Faculty Publications

CDK8/19 kinases, which mediate transcriptional reprogramming, have become an active target for cancer drug discovery. Several small-molecule CDK8/19 inhibitors showed in vivo efficacy and two have entered clinical trials, with no significant toxicities reported. However, Clarke et al. (eLife 2016; 5; e20722) found severe systemic toxicity associated with two potent CDK8/19 inhibitors, Cmpd3 (CCT251921) and Cmpd4 (MSC2530818), and suggested that their toxicity was due to on-target effects. Here, we compared five CDK8/19 inhibitors: Cmpd3, Cmpd4, Senexin B, 16-didehydro-cortistatin A (dCA) and 15w, in different assays. Only Cmpd4 showed striking toxicity in developing zebrafish. In cell-based assays for CDK8 and CDK19 …

Evaluating Controlled Substance Documentation In An Electronic Medical Record, Delora Brooks

Dissertations

The Centers for Disease Control and Prevention (CDC) directives issued in 2016 gave guidelines for safely prescribing opiates; however, primary source discussions about methods used for documenting opioid and controlled substance monitoring within an electronic medical record (EMR) are limited (Hussain, Nelson, Polston & Zheng, 2019). This leaves individual providers to determine the appropriate way to document. Inconsistent documentation may not protect providers or organizations from regulatory, civil or criminal liability. As stated by Raveesh, Nayak & Kumbar (2016), “The best way to handle medico-legal issues is by preventing them”. Even with the advent and widespread use of EMRs, documentation …

The Fallacy Of Enzymatic Hydrolysis For The Determination Of Bioactive Curcumin In Plasma Samples As An Indication Of Bioavailability: A Comparative Study, Sidney J. Stohs, C. Y. O. Chen, Harry G. Preuss, Sidhartha D. Ray, Luke R. Bucci, Jin Ji, Kevin J. Ruff

Touro Scholarly Works

Background

Numerous health benefits have been demonstrated for curcumin which is extracted from turmeric (Curcuma longa L). However, due to its poor absorption in the free form in the gastrointestinal tract and rapid biotransformation, various formulations have been developed to enhance its bioavailability. Previous studies indicate that the free form of curcumin is more bioactive than its conjugated counterparts in target tissues. Most curcumin pharmacokinetics studies in humans designed to assess its absorption and bioavailability have measured and reported total (free plus conjugated) curcumin, but not free, bioactive curcumin in the plasma because enzymatic hydrolysis was employed prior to …

Simulated Biological Fluid Exposure Changes Nanoceria’S Surface Properties But Not Its Biological Response, Robert A. Yokel, Matthew L. Hancock, Benjamin Cherian, Alexandra J. Brooks, Marsha L. Ensor, Hemendra J. Vekaria, Patrick G. Sullivan, Eric A. Grulke

Pharmaceutical Sciences Faculty Publications

Nanoscale cerium dioxide (nanoceria) has industrial applications, capitalizing on its catalytic, abrasive, and energy storage properties. It auto-catalytically cycles between Ce³⁺ and Ce⁴⁺, giving it pro-and anti-oxidative properties. The latter mediates beneficial effects in models of diseases that have oxidative stress/inflammation components. Engineered nanoparticles become coated after body fluid exposure, creating a corona, which can greatly influence their fate and effects. Very little has been reported about nanoceria surface changes and biological effects after pulmonary or gastrointestinal fluid exposure. The study objective was to address the hypothesis that simulated biological fluid (SBF) exposure changes nanoceria’s surface properties …

An Update On Pharmaceutical Strategies For Oral Delivery Of Therapeutic Peptides And Proteins, Nirnoy Dan

Theses and Dissertations (ETD)

Peptides and proteins are imperative for the human body and play crucial roles in governing various bio-chemical processes. Recent advances in molecular biology and biochemistry helped in understanding the role of these endogenous macromolecules in different pathological and disease conditions. Currently, small molecule drugs (< 900dalton) in comparison to the therapeutic peptides and proteins-based drugs (TPP) dominate pharmaceutical market. However, the game is changing with the recent advances of biotechnological tools like recombinant DNA technology, solid phase protein synthesis etc., which enabled large-scale production of therapeutic peptides and proteins. The Success of Human Insulin, the first FDA approved commercial recombinant protein based therapeutic in 1982, revolutionized the field of TPPs. The number of FDA approved TPPs reached about to ~239 in 2017 compared to where it was only ~130 in 2008. Rapid progress in this sector can be attributed to several advantages of proteins and peptides over small molecule drugs both financially and clinically. From a clinical perspective, proteins and peptides are inherently more specific to the target site than the small molecules drugs, which lead to less interferences with normal biological system of the patient and caused minimal off-target side effects. A handful of proteins which are used for different clinical complications are less immunogenic because they are produced in the body naturally. Furthermore, proteins and peptides also take part in several complex and complicated biological processes, which is difficult to be to be mimicked by the small molecule drugs. From a financial standpoint, median total pre-market development times were shorter for biologics (10.6 years) than the small molecules drugs (12.6 years) estimated using Merck Index. In 2009, US Congress passed the Biologics Price Competition and Innovation Act (BPCIA) which gave new biologics 12 years of guaranteed exclusivity. The most commonly utilized routes for administering TPPs are I.V, I.P or I.M injections, which largely suffer from patient compliances. There are ~350 TPPs under clinical development and among them only 2 are given orally which is Interferon-α and Human growth hormone. Currently, most efforts in both industry and academia are centered around enhancing bioavailability of orally administered TPPs which typically are less than 1%. Oral administration is the non-invasive, most preferred route of drug administration for the patients. Furthermore, oral dosage forms are cheaper to manufacture as well as to administer, because they do not need to be produced under sterile conditions or administered in clinics. However, unfavorable physicochemical characteristics of TPPs like high molecular weight, hydrophilicity, poor stability in the physiological conditions, short biological half-life, low permeability through the epithelial barrier in the small intestine put up a massive barrier in the development of orally available dosage forms of TPPs. In this review, we will discuss the challenges associated with oral delivery of TPPs and the ongoing efforts to solve them.
