Disrupting the Conserved Salt Bridge in the Trimerization of Influenza A Nucleoprotein

Antiviral drug resistance in influenza infections has been a major threat to public health. To develop a broad-spectrum inhibitor of influenza to combat the problem of drug resistance, we previously identified the highly conserved E339?R416 salt bridge of the nucleoprotein trimer as a target and compound 1 as an inhibitor disrupting the salt bridge with an EC50 = 2.7 μM against influenza A (A/WSN/1933). We have further modified this compound via a structure-based approach and performed antiviral activity screening to identify compounds 29 and 30 with EC50 values of 110 and 120 nM, respectively, and without measurable host cell cytotoxicity. Compared to the clinically used neuraminidase inhibitors, these two compounds showed better activity profiles against drug-resistant influenza A strains, as well as influenza B, and improved survival of influenza-infected mice.

Solvent-free synthesis of bacillamide analogues as novel cytotoxic and anti-inflammatory agents

Synthesis of fourteen analogues of bacillamide, a bioactive tryptamide alkaloid of marine origin, has been accomplished through a highly efficient convergent route. The present solvent-free protocol involves the formation of thiazole ring in the initial step followed by amide coupling between substituted ethyl 2-alkyl/aryl/heteroaryl/amino/aminoarylthiazole-4-carboxylates and tryptamine in presence of 2-hydroxy-4,6-dimethylpyrimidine, a solid phase catalyst to yield N-[2-(1H-indol-3-yl)ethyl]-2-alkyl/aryl/heteroaryl/amino/aminoarylthiazole-4-carboxamides as bacillamide analogues having structural variation at position-2 of thiazole ring. Bacillamide and its analogues were evaluated for their cytotoxic activity against three cancer cell lines (HCT-116, MDA-MD-231 and JURKAT cell lines) using colorimetric cell proliferation assay. Compounds 17a and 17b exhibited potent anti-cell proliferation activity with IC50values in the range of ～3.0?μM and ～0.1–0.6?μM, respectively against these cell lines. Preliminary mechanism of action studies indicates that these compounds initiate caspase dependent apoptosis. Also, compounds 16d, 16f, 17a and 17d exhibited excellent anti-inflammatory activity comparable to well-known NSAID indomethacin and better to bacillamide, when evaluated using carrageenan induced rat hind paw oedema method.

Ethyl 2-((4-Chlorophenyl)amino)thiazole-4-carboxylate and Derivatives Are Potent Inducers of Oct3/4

The octamer-binding transcription factor 4 (Oct3/4) is a master gene in the transcriptional regulatory network of pluripotent cells. Repression of Oct3/4 in embryonic stem cells (ESCs) is associated with cell differentiation and loss of pluripotency, wher

The discovery of potent blockers of the canonical transient receptor channels, TRPC3 and TRPC6, based on an anilino-thiazole pharmacophore

Lead optimization of piperidine amide HTS hits, based on an anilino-thiazole core, led to the identification of analogs which displayed low nanomolar blocking activity at the canonical transient receptor channels 3 and 6 (TRPC3 & 6) based on FLIPR (carbac
