Abstract
A simple, efficient, and transition metal-free approach was developed for accessing 4-thio-substituted chroman and diarylmethyl thioethers from sulfonyl hydrazones. This protocol provides straightforward access to a class of diarylmethane derivatives with good to excellent yields. This operationally simple protocol exhibited good tolerance for labile functional groups, providing biologically relevant chemical libraries. This safe and feasible route is applicable to the large-scale synthesis of 4-thio-substituted chromans, which are of great synthetic interest because of their further reaction potential.

Synthesis of novel spirobibenzopyrans as potent anticancer leads inducing apoptosis in HeLa cells. Bioorg Med Chem Lett 2020; 30:127199. [PMID: 32331934 DOI: 10.1016/j.bmcl.2020.127199] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 04/12/2020] [Accepted: 04/14/2020] [Indexed: 12/13/2022]
Abstract
Spirobibenzopyrans are an unexplored class of therapeutics. We report the anticancer activity of novel spirobibenzopyrans, synthesized by a one-pot reaction and extensively characterized. Structure of one of the spirobibenzopyran has been determined by the single crystal XRD technique. The in vitro anticancer activity of these derivatives across the NCI 60-cell line panel was evaluated and for the first time their mechanism of action against HeLa cells was probed via cell morphology analysis and cell cycle analysis. They were determined to be apoptosis inducers with cell cycle arrest in G0/G1 and S phase suggesting CDK-4 protein inhibition and the inhibition of DNA replication. The DNA inhibition was studied and confirmed using the alkaline comet assay for the compound CHX-4MO-SAL showing S phase inhibition. Further, conformity with the in silico Lipinski's score signify the potential of spirobibenzopyrans as anticancer leads.
