Design And Synthesis Of Novel Sultams As Non-Nucleoside Inhibitors Of Hiv Reverse Transcriptase, Brian Chadwick Lecroix
Design And Synthesis Of Novel Sultams As Non-Nucleoside Inhibitors Of Hiv Reverse Transcriptase, Brian Chadwick Lecroix
Doctoral Dissertations
The compound 2-methyl-3-phenyl-2,3-dihydro-1,2-benzisothiazole 1,1-dioxide (NSC 108406) was identified as an HIV-1 reverse transcriptase inhibitor by the National Cancer Institute. Using this lead, the Baker group has developed a series of analogues with various groups at the 3-position that show a spectrum of biological activities. In the end, the substituents used could not compare to the biological activity of the inhibitor efavirenz (Sustiva® [trademark]), and so it was decided to synthesize sultams with alkylethynyl substituents at the 3-position of the sultams in an attempt to mimic the activity of efavirenz.
Previous research analyzed the proposed novel sultams in the modeling …
Resveratrol Induced Apoptosis In A Human Adenosquamous Carcinoma Cell Line (Cal-27 Cells), Saquib A. Siddiqi
Resveratrol Induced Apoptosis In A Human Adenosquamous Carcinoma Cell Line (Cal-27 Cells), Saquib A. Siddiqi
PCOM Biomedical Studies Student Scholarship
Radiotherapy and surgery are the two principal modalities in the treatment of head and neck cancers, and both therapies can result in severe adverse effects and ultimately lower the quality of life. It is of paramount importance to develop reagents that target the cancer cell specifically without affecting the normal non-cancer cells. Using the tongue cancer cell line Cal 27 as a model system, we dissected the molecular mechanism of the resveratrol-induced cancer cell apoptosis. After demonstrating that resveratrol induces the cancer cell apoptosis in a dose- and time-dependent manner, a systemic apoptosis protein array was conducted to identify the …
Kinetics And Mechanism Of S-Nitrosation And Oxidation Of Cysteamine By Peroxynitrite, Wilbes Mbiya
Kinetics And Mechanism Of S-Nitrosation And Oxidation Of Cysteamine By Peroxynitrite, Wilbes Mbiya
Dissertations and Theses
Cysteamine (CA), which is an aminothiol drug medically known as Cystagon® was studied in this thesis. Cysteamine was reacted with a binary toxin called peroxynitrite (PN) which is assembled spontaneously whenever nitric oxide and superoxide are produced together and the decomposition of peroxyinitrite was monitored. PN was able to nitrosate CA in highly acidic medium and excess CA to form S-nitrosocysteamine (CANO) in a 1:1 with the formation of one mole of CANO from one mole of ONOOH. In excess oxidant (PN) the following 1:2 stoichiometric ratio was obtained; ONOO- + 2CA → CA-CA + NO2- + H …
Synthesis And Stability Studies Of Prodrugs And Codrugs Of Naltrexone And 6-Β-Naltrexol, Joshua A. Eldridge
Synthesis And Stability Studies Of Prodrugs And Codrugs Of Naltrexone And 6-Β-Naltrexol, Joshua A. Eldridge
Theses and Dissertations--Pharmacy
The present study was divided between two different drug delivery goals, each involving naltrexone (NTX) or its active metabolite, 6-β-naltrexol (NTXOL). First, amino acid esters of NTX and NTXOL were prepared in order to test their candidacy for microneedle-enhanced transdermal delivery. Second, a 3-O-(-)-cytisine-naltrexone (CYT-NTX) codrug was prepared for screening as a potential oral delivery form of NTX and (-)-cytisine (CYT). The amino acid prodrugs were intended for the treatment of alcohol abuse, while the codrug was designed as a single agent for the treatment of alcoholism and tobacco-dependency co-morbidities. One hypothesis of this work was that prodrugs …
