Design And Investigation Of Small Molecule Drugs For Potential Treatment Of Cns Disorders, Flaviviral Infections, And Cancers, Viktoriya Mashinson
Design And Investigation Of Small Molecule Drugs For Potential Treatment Of Cns Disorders, Flaviviral Infections, And Cancers, Viktoriya Mashinson

Chapter 1 discusses the development of antagonists against the dopamine 4 receptor (D4R) that is expressed in the motor, associative, and limbic subdivisions of the basal ganglia network and is involved in Parkinson’s disease (PD). Levodopa is the firstline drug for the management of PD symptoms but its long-term use often leads to development of levodopa-induced dyskinesia (LID). D4R antagonists have been shown to decrease the abnormal involuntary movement scores in mouse models of LID. Chapter 1 outlines the development and optimization of selective D4R antagonists for potential treatment of LID. During the investigation of our D4R antagonists we discovered …

Dopamine (DA) is an important neurotransmitter for the regulation and long-term function of the central nervous system (CNS). DA binds to Dopamine Receptors (DR) to stimulate or inhibit adenyl cyclase production to further elicit a pharmacological response. DRs were cloned, and it was determined that there are two families separated by their function and five total subtypes distinguished by their amino acid structure. The Dopamine 4 receptor (D4R) is the second least studied subtype but has high expression in the frontal cortex, amygdala, hippocampus, hypothalamus, globus pallidus, substantia nigra pars reticula, and thalamus. Dopamine signaling and transmission, especially in the …

Neuropilin-2 In Advanced Prostate Cancer And Its Targeting With Novel Small Molecule Inhibitors, Ridwan Islam
Theses & Dissertations
Despite the development of new therapies, clinical management of advanced metastatic castrationresistant prostate cancer (mCRPC) still remains challenging owing to the emergence of therapy resistance. Resistance to the therapies is driven by both AR and non-AR pathways. Non-AR pathway is characterized by a lineage switch that leads to the development of neuroendocrine-like (NE-like) prostate cancer (PCa), which has a fulminant clinical course due to the lack of effective treatment strategy. Therefore, novel molecular targets need to be identified to develop effective therapeutic regimen to improve the outcomes in advanced PCa patients including NE-like PCa. Recent investigation on advanced PCa patients …

The G protein regulated inwardly rectifying potassium channels (GIRK) are a family of inwardly rectifying potassium channels and are key effectors in signaling pathways. GIRK 1/2 channel subunit, predominantly found in the brain, is involved pathophysiology of various neurological disorders including, but not limited to, epilepsy, anxiety, Parkinson's, pain, reward, and addiction. Previously, our laboratory had identified a series of urea containing molecules as GIRK1/2 preferring activators. Unfortunately, the urea series suffers from significant PK liabilities (solubility, brain penetration and high clearance). The chapter 1 of the dissertation describes our efforts in developing three new series of activators with improved …

Long-acting cabotegravir (CAB) extends antiretroviral drug (ARV) dosing to monthly for maintenance of human immunodeficiency virus type one (HIV-1) suppression and to every other month for prevention of viral transmission. However, injection dose volumes, site reactions, and clinical oversights that are required remain obstacles towards broad usage. To meet these needs, surfactant coated hydrophobic and lipophilic CAB prodrugs were created with controlled prodrug dissolution, hydrolysis and drug tissue penetration. To such ends, fatty acid ester CAB nanocrystal prodrugs with 14, 18, and 22 added carbon chains were synthesized then nanoformulated as NMCAB, NM2CAB, and NM3CAB. These nanocrystal formulations were tested …

Synthesis And Characterization Of Long Acting Darunavir Prodrugs, Mary Banoub
Theses & Dissertations
Patient adherence is critical for ART success to ensure adequate viral suppression, therefore, long-acting antiretrovirals are soon replacing current daily regimens. In recent years, two drugs were successfully transformed into long-acting injectables; CAB LA and RPV LA. These long-acting nanoformulations made it possible to abandon the daily pill burden, instead approximately a bimonthly injection of both drugs is enough to suppress and maintain viral load suppression. Our laboratory has been instrumental in transforming FDA-approved and experimental-HIV medications into long-acting slow effective release drugs, also known as LASER ART. LASER ART consists of slow drug metabolism and high permeability and retention …
