Au(I)-catalyzed synthesis of 8-oxabicyclo[3.2.1]oct-2-enes and 9-oxabicyclo[3.3.1]nona-2,6-dienes from enynol via oxonium/Prins-type cyclization.

A sustainable and simple Au(I) catalytic system to synthesise 8-oxabicyclo[3.2.1]oct-2-enes and 9-oxabicyclo[3.

Synthesis, DNA-binding abilities and anticancer activities of triazole-pyrrolo[2,1-c][1,4]benzodiazepines hybrid scaffolds.

We synthesized a new series of PBD-hybrid derivatives having tethered triazoles and investigated for their cytotoxicity. The studies indicated that cis-olefin compounds induce higher cytotoxicity with increase in the G1 cell cycle phase compared with the trans-compounds. Quantitative RT-PCR assay indicated that compounds (16a-d) induced G1 phase arrest through down-regulation of cyclin D1 and up-regulation of p21, p27, and p53 mRNA expressions.
