Design and Synthesis of Pyridyl and 2-Hydroxyphenyl Chalcones with Antitubercular Activity.

ABSTRACT: A focussed library of pyridyl and 2-hydroxyphenyl chalcones were synthesized and tested for growth inhibitory activity against Mycobacterium tuberculosis H37Rv, and normal and cancer breast cell lines. Pyridyl chalcones bearing lipophilic A-ring, e.g., dichloro-phenyl-(14), pyrene-1-yl (20)- and biphenyl-4-yl (21) moieties were found to be the most potent of the series inhibiting the growth of M. tuberculosis H37Rv with IC₉₀ values ranging from 8.9-28 µM. Aryl chalcones containing a 3-methoxyphenyl A-ring and either p-Br-phenyl (25) or p-Cl-phenyl (26) B-rings showed an IC₉₀ value of 28 µM. Aryl-chalcones were generally less toxic to HepG2 cells compared to pyridyl-chalcones. Dose-dependent antiproliferati
