摘要:
3-(4-Fluorophenyl)-2-(4-pyridyl)chromone derivatives were synthesized and evaluated as p38 MAP kinase inhibitors. Introduction of an amino group in the 2-position of the pyridyl moiety gave p38 alpha inhibitors with IC50 in the low nanomolar range (e.g., 8a, IC50 = 17 nm). The inhibitors (8a and 8e) showed excellent selectivity profiles when tested on a panel of 62 kinases, as well as efficient inhibition (8e) of p38 signaling in human breast cancer cells.
