2-Aryl substituted thiazoles 3a-k were prepared by oxidative insertion of zinc into 2-bromothiazole (1) followed by palladium(0)-catalyzed Negishi cross-coupling in a one-pot procedure. 5-Aryl substituted thiazoles 6a-i were prepared by regioselective C-5 lithiation of 2-(trimethylsilyl)thiazole (4) followed by transmetalation with zinc chloride and palladium(0)-catalyzed Negishi cross-coupling in a one-pot procedure. The synthetic sequences were combined to give 2,5-diaryl substituted thiazoles 8a,b and 10 via stepwise C-2 and C-5 arylation and vice versa.

This study evaluated the potential use of senescence-inducing small molecules in the treatment of melanoma. We screened commercially available small-molecule libraries with high-throughput screening and high-content screening image-based technology. Our findings showed an initial hit with the embedded N-arylpiperidine-3-carboxamide scaffold-induced senescence-like phenotypic changes in human melanoma A375 cells without serious cytotoxicity against normal cells. A focused library containing diversely modified analogues were constructed and examined to evaluate the structure-activity relationship of N-arylpiperidine-3-carboxamide derivatives starting from hit 1. This work identified a novel compound with remarkable antiproliferative activity in vitro and demonstrated the key structural moieties within.
