Pd-catalytic C-S activation was successfully applied to initiate the cross-coupling of (2-methylthio-3-ester)benzofurans with 2-hydroxyphenylboronic acids and sequential intramolecular transesterification process under Liebeskind-Srogl conditions. Thus, a novel [3 + 3] annulation strategy for efficient synthesis of coumestan derivatives has been developed from readily available starting materials.

Inhibition of the mycolic acid pathway has proven a viable strategy in antitubercular drug discovery. The AccA3/AccD4/FadD32/Pks13 complex of Mycobacterium tuberculosis constitutes an essential biosynthetic mechanism for mycolic acids. Small molecules targeting the thioesterase domain of Pks13 have been reported, including a benzofuran-based compound whose X-ray cocrystal structure has been very recently solved. Its initial inactivity in a serum inhibition titration (SIT) assay led us to further probe other structurally related benzofurans with the aim to improve their potency and bioavailability. Herein, we report our preliminary structure-activity relationship studies around this scaffold, highlighting a natural product-inspired cyclization strategy to form coumestans that are shown to be active in SIT. Whole genome deep sequencing of the coumestan-resistant mutants confirmed a single nucleotide polymorphism in the pks13 gene responsible for the resistance phenotype, demonstrating the druggability of this target for the development of new antitubercular agents.

The invention relates to chemical compounds that are useful as inhibitors of mechanotransduction in the treatment of pain and modulation of touch perception. The invention further relates to the topical administration of the compounds described herein in

Several new benzofuran derivatives were synthesized, via appropriate synthetic route as anti-inflammatory agents. The anti-inflammatory activity of the prepared compounds was evaluated using carrageenan rat model. Among the synthesized compounds, some compounds showed comparable anti-inflammatory activity to nimesulide, the standard drug taken for anti-inflammatory studies. Docking study of the prepared compounds was performed for the study of interaction of molecules with the active site of COX-2. Preliminary biological studies and docking gave an interesting insight, into the validity of employing benzofuran analogues as good anti-inflammatory agent.
