In this study, a series of novel N-(4-phenylthiazol-2-yl)cinnamamide derivatives (7a-8n) were synthesized and evaluated for their anti-proliferative activities in vitro by MTT assay and a possible antitumor mechanism was also explored. SAR analysis showed that steric effects played an important role on the anti-tumor activity. The most potent analogue 8f showed excellent inhibitions on the K562, Bel7402, A549 and Jurkat cells ranging from sub-micromolar to nanomolar concentration. Compound 8f inhibited Jurkat cells with an IC50 value of 0.035 μM with no apparent toxicity in different non-cancerous cells. Furthermore, it was suggested that the possible mechanism of 8f might be associated with inducing cancer cell apoptosis following flow cytometer analysis and Hoechst 33358 staining assays.

A series of 4-aryl-N-arylcarbonyl-2-aminothiazoles of scaffold 4 was designed and synthesized as Hec1/Nek2 inhibitors. Structural optimization of 4 led to compound 32 bearing C-4′ 4-methoxyphenoxy and 4-(o-fluoropyridyl) carbonyl groups that showed low nanomolar in vitro antiproliferative activity (IC50: 16.3-42.7 nM), high intravenous AUC (64.9 μM·h, 2.0 mg/kg) in SD rats, and significant in vivo antitumor activity (T/C = 32%, 20 mg/kg, IV) in mice bearing human MDA-MB-231 xenografts. Cell responses resulting from Hec1/Nek2 inhibition were observed in cells treated with 32, including a reduced level of Hec1 coimmunoprecipitated with Nek2, degradation of Nek2, mitotic abnormalities, and apoptosis. Compound 32 showed selectivity toward cancer cells over normal phenotype cells and was inactive in a [ 3H]astemizole competitive binding assay for hERG liability screening. Therefore, 32 is as a good lead toward the discovery of a preclinical candidate targeting Hec1/Nek2 interaction.
