By Rashed M. Almuqbil, Pharm.D.

Director: Sandro R.P. da Rocha, PhD

Cancer is a leading cause of death worldwide. The available treatment for solid tumors may include surgery, radiotherapy, immunotherapy, and chemotherapy or a combination of all those regimens. Chemotherapy is widely used in the treatment of both lung cancers and breast cancer, including metastases, irrespective of type and stage. The poor rates of survival can be attributed to late diagnosis, and due to the development of acquired and innate chemoresistance. Lung tumors are intrinsically …

Standardization Of E-Cigarette Research: Addressing The Analysis Of Total Nicotine And Free Base Nicotine In E-Cigarettes, Vinit Gholap

Theses and Dissertations

Electronic cigarettes (e-cigarettes) are one of the major sources of exposure to nicotine, an addictive chemical. Since 2016, the Food and Drug Administration (FDA) has started regulating these products under the Tobacco Control Act yet, specifications about the nicotine content in these products have not been established. In e-cigarettes, nicotine concentration ranges from 0 to >50mg/mL. Additionally, several e-cigarette related parameters have been identified which can affect nicotine delivery to users. Of these factors, nicotine forms (protonated and free base) have been found to play a significant role in nicotine absorption profiles yet, a limited and contradictory research is available …

De Novo Prediction Of Drug–Target Interactions Using Laplacian Regularized Schatten P-Norm Minimization, Gaoyan Wu, Mengyun Yang, Yaohang Li, Jianxin Wang

Computer Science Faculty Publications

In pharmaceutical sciences, a crucial step of the drug discovery is the identification of drug–target interactions (DTIs). However, only a small portion of the DTIs have been experimentally validated. Moreover, it is an extremely laborious, expensive, and time-consuming procedure to capture new interactions between drugs and targets through traditional biochemical experiments. Therefore, designing computational methods for predicting potential interactions to guide the experimental verification is of practical significance, especially for de novo situation. In this article, we propose a new algorithm, namely Laplacian regularized Schatten p-norm minimization (LRSpNM), to predict potential target proteins for novel drugs and potential drugs for …

Responses Of Predatory Myxobacteria To Prey Signaling Molecules & Features Of A Pseudomonas Prey Avoiding Predation, Shukria Akbar

Electronic Theses and Dissertations

Gram-negative unicellular myxobacteria, along with their multicellular lifestyle andbiologically active specialized metabolites, are known for the predatory interactions with Gram-negative/ Gram-positive bacteria and fungi. Although myxobacterial predation range have been exploited extensively, little is known about the prey associated molecules contributing to myxobacterial predator-prey dynamics. By employing transcriptomics and untargeted metabolomics approaches, we demonstrate two structurally distinct classes of signaling molecules from Gram-negative bacterial prey elicit significant omics responses from myxobacteria, Myxococcus xanthus and Cystobacter ferrugineus. An overlapping and general response to acylhomoserine lactones, whereas a distinctive response to a quinolone signaling molecule is observed from both myxobacteria. Similarly, by …

Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh

Electronic Theses and Dissertations

In the rhizosphere, plants curate and maintain distinct rhizobiome, some of which serve as secondary defense mechanisms against pathogenic microorganisms. Additionally, in response to biotic stress, plants generate phytohormones which regulate signaling pathways to activate systemic resistance. These phytohormones contribute to the chemical space within the rhizosphere in addition to other low-molecular-weight metabolites used for cell-to-cell communication within species and across kingdoms. However, little is known about the influences of stress-related phytohormones on beneficial bacteria even though biocontrol strategies abundantly explore plant-beneficial microorganisms to manage pathogens in agricultural systems. Myxobacteria are competent predators of plant pathogens and have demonstrated responses …

Influence Of Rage Signaling On Cellular Communication In Diabetes-Mediated Vascular Calcification, Amber Michelle Kennon

Electronic Theses and Dissertations

Chronic hyperglycemia is one of the main characteristics of type 2 diabetes mellitus (T2DM). With the increased prevalence of T2DM, the risk of cardiovascular complications, including heart attack or stroke, is increased. Complications linked to the vasculature are increased vascular calcification (VC) or mineral deposition within the medial layer of conducting arteries. Under calcification conditions, vascular smooth muscle cells (VSMCs) undergo an osteogenic switch to an osteoblast-like cell and begin producing bone proteins. Chronic hyperglycemia can also result in increased extracellular matrix (ECM) synthesis, accumulation, and crosslinking. One of the cell types responsible for increased ECM synthesis are ‘activated’ fibroblasts …

Correlation Of Cyp2d6 Polymorphisms And Pharmacokinetics Of Primaquine In Thai Army Population On The Thailand-Cambodia Border Area, Waritda Pookmanee

Chulalongkorn University Theses and Dissertations (Chula ETD)

The antimalarial drug primaquine (PQ), which has minimal activity, has to be metabolized through the CYP2D6 enzyme for its most effective antimalarial activity. The stable form 5,6-orthoquinone-primaquine (5,6-PQ) was used as a representative marker for PQ active metabolite quantification. However, the relationship between CYP2D6 polymorphisms and the pharmacokinetic (PK) parameters of 5,6-PQ has not been reported. We assessed the relationship between CYP2D6 polymorphisms and PKs of both PQ and 5,6-PQ in the Thai army population on the Thailand-Cambodia border area. We found that 56% of volunteers were CYP2D6 normal metabolizers (CYP2D6 NMs) and 44% were CYP2D6 intermediate metabolizers (CYP2D6 IMs). …

Protective Effect Of Intranasal Asiatic Acid In Scopolamine-Induced Memory Impairment In Mice, Su Lwin Lwin Myint

Chulalongkorn University Theses and Dissertations (Chula ETD)

Asiatic acid (AA), a major constituent of Centella asiatica extract, possesses various pharmacological activities including antioxidant, anti-inflammation, and neuroprotective effects. Low oral bioavailability has limited AA penetration to the brain. The intranasal administration increases the efficacy of drug by passing blood brain barrier and by avoiding the metabolism by hepatic enzyme. This study investigated the protective effect and the mechanisms of intranasal asiatic acid in scopolamine-induced memory impairment in mice. Mice are divided into seven groups; control (Con), scopolamine (3 mg/kg; Sco), scopolamine plus donepezil (3 mg/kg; Don), scopolamine plus intranasal asiatic acid (2.31 mg/kg; INAA) and scopolamine plus oral …

Rap1a Overlaps The Age/Rage Signaling Cascade In Type 2 Diabetes Mellitus, Stephanie Burr

Electronic Theses and Dissertations

Diabetic individuals have an increased risk for developing cardiovascular disease due to stiffening of the left ventricle, which is thought to occur, in part, by increased AGE/RAGE signaling. Advanced glycation end products (AGEs) accumulate within the body over time, and under hyperglycemic conditions, the formation and accumulation of AGEs is accelerated. AGEs exert their effect by binding to their receptor (RAGE) and can induce myofibroblast differentiation, oxidative stress, cell-extracellular matrix contraction, and cell migration. Previous findings from our lab have demonstrated that preventing the production of Rap1a, a Ras-like GTPase signaling protein, in cardiac fibroblasts will decrease type 2 diabetes …

Methylene Blue As Light And Reactive Oxygen Species Sensitive Ligand: Appicability In Hybrid Drug And Material Synthesis, Huy Dao

Electronic Theses and Dissertations

Methylene blue (MB) with a 10-N-carbamoyl linkage was discovered and developed as a multifunctional far-red (660 nm) photocleavable ligand capable of rendering a series of MB conjugated compounds with off-to-on fluorescence switch properties through the controlled release of MB. The released MB was successfully demonstrated to be an effective photosensitizer, imaging probe, and therapeutic agent. The complete release of MB was achieved with a cumulative light dose of 15 J/cm2. The photosensitivity was demonstrated to be dependent on the type of chemical bond at 10-N of the phenothiazine ring which links MB to a side group. Specifically, the urea bond-based …
