The Use Of Heterocycles As Important Structures In Medicinal Chemistry, Sayre Weast May 2019

The Use Of Heterocycles As Important Structures In Medicinal Chemistry, Sayre Weast

Honors Theses

Heterocycles have many applications in the discipline of medicinal chemistry. These structures are found in various natural products with relevant biological activity. Our research group, in collaboration with two others, is particularly interested in one heterocycle, quinoline, as a scaffold for HIV-1 integrase inhibitors. A synthetic route has been developed to produce a derivatized structure on small scale. One goal of this thesis was to expand the scale of this route to provide increased quantities of the quinoline scaffold. Procedures were adapted to accommodate the increase in scale to convert commercially available anthranilic acids to quinolines via the isatoic anhydride ...


A Potential Improved Anti-Hiv Drug: Using A Bivalent Design To Increase Specificity And Potency, Theo Koelsch Jan 2017

A Potential Improved Anti-Hiv Drug: Using A Bivalent Design To Increase Specificity And Potency, Theo Koelsch

Undergraduate Honors Theses

In this thesis, the synthesis of a potentially improved HIV entry inhibitor is presented. HIV has infected millions of people, and yet there is no fully effective treatment for the infection and the subsequent, high mortality disease AIDS. This is due in large part to the virus’s rapid development of resistance to any drug used to treat the infection. The best way to combat this is to use multiple drugs with different inhibition targets and so prevent the virus from developing resistance. In order to contribute to the effective treatment of HIV infection, it is therefore important to develop ...


Design And Synthesis Of Novel Sultams As Non-Nucleoside Inhibitors Of Hiv Reverse Transcriptase, Brian Chadwick Lecroix Dec 2013

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 ...

Ongoing studies have developed strategies for identifying key bioactive compounds and chemical profiles in Echinacea with the goal of improving its human health benefits. Antiviral and antiinflammatory–antipain assays have targeted various classes of chemicals responsible for these activities. Analysis of polar fractions of E. purpurea extracts showed the presence of antiviral activity, with evidence suggesting that polyphenolic compounds other than the known HIV inhibitor, cichoric acid, may be involved. Antiinflammatory activity differed by species, with E. sanguinea having the greatest activity and E. angustifolia, E. pallida, and E. simulata having somewhat less. Fractionation and studies with pure compounds indicate ...
