A series of thieno[2,3-d]pyrimidines and furo[2,3-d] pyrimidines were synthesized and evaluated for the c-Met inhibition. Thieno[2,3-d]pyrimidine 6b stood out as the most potent showing an IC(50) of 35.7 nM. This compound displayed high inhibitory effect on cell proliferation in BaF3-TPR-Met cells and showed high selectivity for c-Met family against other 14 tested kinases. However, compound 6b was found ineffective in the c-Met-dependent U-87MG human gliobastoma xenograft model that may be relevant to its poor PK profile. (C) 2011 Elsevier Ltd. All rights
Synthesis and bioevaluation study of novel N -methylpicolinamide and thienopyrimidine derivatives as selectivity c-Met kinase inhibitors
Four series of N-methylpicolinamide moiety and thienopyrimidine moiety bearing pyridazinone were designed and synthesized and evaluated for the IC50 values against three cancer cell lines (A549, HepG2 and MCF-7) and some selected compounds were further evaluated for the activity against c-Met, Flt-3, VEGFR-2, c-Kit and EGFR kinases. Three compounds (35, 39 and 43) showed more active than positive control
Design, synthesis, and biological evaluation of thiazole/thiadiazole carboxamide scaffold-based derivatives as potential c-Met kinase inhibitors for cancer treatment
continuous efforts to discover novel c-Met inhibitors as antitumor agents, four series of thiazole/thiadiazole carboxamide-derived analogues were designed, synthesised, and evaluated for the in vitro activity against c-Met and four human cancer cell lines. After five cycles of optimisation on structure–activity relationship, compound 51am was found to be the most promising inhibitor in both biochemical and
