cytotoxicity in the NCI-60 panel of cell lines with an average IC50 of 1.04 μM. In addition, 5 has a unique mechanism of action in comparison with standard agents in the NCI database based on COMPARE analysis. Further structure–activityrelationship study led to the development of a more potent analogue, compound 7d, with an IC50 of 640 nM in HL60/MX2. Additionally, one enantiomer of 5 is 13-fold more active
On the basis of our recently reported aniline aqueous borylation, molecular diversity was achieved in a one-pot process by combining other reactions such as esterification, Suzuki-Miyaura coupling, hydrogenolysis, or Petasis borono-Mannich.
Synthesis and Biological Evaluation of (6- and 7-Phenyl) Coumarin Derivatives as Selective Nonsteroidal Inhibitors of 17β-Hydroxysteroid Dehydrogenase Type 1
coumarines 1 and 2 significantly inhibit 17β-HSD1 in a recombinant enzyme assay, with high selectivity against 17β-HSD2. We postulated that the introduction of various p-substituted phenyl moieties to position 6 or 7 of the coumarin core using the Suzuki-Miyaura cross-coupling reaction would provide mimetics of steroidal structures with improved inhibition of 17β-HSD1. The best inhibitor in the series

derivatives and isosteres were synthesized from the reaction of triflic intermediates with phenylboronic acids, terminal alkynes, and organozinc compounds through palladium-catalyzed cross-coupling reactions. The in vitro cytotoxiceffect of the compounds was evaluated against two non-small celllung carcinoma (NSCLC) cell lines (A-549 and H2170) and a normal cell line (NIH-3T3) using cisplatin as a reference
