- Discovery of (3-Benzyl-5-hydroxyphenyl)carbamates as new antitubercular agents with potent in vitro and in vivo efficacy
-
A series of 3-amino-5-benzylphenol derivatives were designed and synthesized. Among them, (3-benzyl-5-hydroxyphenyl)carbamates were found to exert good inhibitory activity against M. tuberculosis H37Ra, H37Rv and clinically isolated multidrug-resistant M. tuberculosis strains (MIC = 0.625-6.25 μg/mL). The privileged compounds 3i and 3l showed moderate cytotoxicity against cell line A549. Compound 3l also exhibited potent in vivo inhibitory activity on a mouse infection model via the oral administration. The results demonstrated 3-hydroxyphenylcarbamates as a class of new antitubercular agents with good potential.

- Design, synthesis, and biological evaluation of m-amidophenol derivatives as a new class of antitubercular agents
-
A series of m-amidophenol derivatives (6a-6l, 7a-7q, 9a, 9b, 12a-12c, 14 and 15) were designed and synthesized. Their antitubercular activities were evaluated in vitro against M. tuberculosis strains H37Ra and H37Rv and clinically isolated multidrug-resistant M. tuberculosis strains. Ten compounds displayed minimal inhibitory concentrations (MICs) against M. tuberculosis H37Ra below 2.5 μg mL?1 and 6g was the most active compound (MIC = 0.625 μg mL?1). Compounds 6g and 7a also showed potent inhibitory activity against M. tuberculosis H37Rv (MIC = 0.39 μg mL?1) and several clinically isolated multidrug-resistant M. tuberculosis strains (MIC = 0.39-3.125 μg mL?1). The compounds did not show inhibitory activity against normal Gram-positive and Gram-negative bacteria. They exhibited low cytotoxicity against HepG2 and RAW264.7 cell lines. The results demonstrated m-amidophenol as an attractive scaffold for the development of new antitubercular agents.

- Monoenomycin: A simplified trienomycin A analogue that manifests anticancer activity
-
Macrocyclic natural products are a powerful class of leadlike chemical entities. Despite commonly violating Lipinski's "rule of 5", these compounds often demonstrate superior druglike physicochemical and pharmacokinetic attributes when compared to their acyclic counterparts. However, the elaborate structural architectures of such molecules require rigorous synthetic investigation that complicates analogue development and their application to drug discovery programs. To circumvent these limitations, a conformation-based approach using limited structure-activity relationships and molecular modeling was implemented to design simplified analogues of trienomycin A, in which the corresponding analogues could be prepared in a succinct manner to rapidly identify essential structural components necessary for biological activity. Trienomycin A is a member of the ansamycin family of natural products that possesses potent anticancer activity. These studies revealed a novel trienomycin A analogue, monoenomycin, which manifests potent anticancer activity.

-
Disclosed are isolated, unnatural polypeptides containing cyclically-constrained β-amino acid residues and cyclically-constrained γ-amino acid residues. The compounds are unnatural and because they contain rotationally constrained residues that are not amenable to enzymatic degradation, the compounds are useful to probe protein-protein and other large molecule interactions.
