2-(3′,4′-Dimethoxybenzylidene)tetralone induces anti-breast cancer activity through microtubule stabilization and activation of reactive oxygen species
Compounds 13, 15 and 19 significantly stabilized tubulin polymerization and arrested cell cycle progression at G0/G1 phase instead of typical mitotic arrest at G2/M phase as observed in case of tubulin polymerization modulators suggesting induction of mitotic slippage followed by cell death. Further, mechanistic studies revealed that compound 13 induced reactive oxygen species generation and apoptosis in breast

3-Arylidenechroman-4-ones and 2-arylidene-1-tetralones are hydrogenated to cis-benzylic alcohols in dr’s and er’s up to 99:1 via a C═C and C═O one-pot reduction in the presence of 2–5 mol % Noyori–Ikariya-type RuII chiral complexes and HCO2Na as a hydrogen source under asymmetric transfer hydrogenation–dynamic kinetic resolution (ATH-DKR) conditions. The oxidation of theses substrates resulted in the
