In continuing our efforts to find new effective antimicrobial agents for overcoming the problem of microbial resistance, a new series of functionalized 5-hetarylthiazoles have been designed and synthesized starting from readily accessible 1-(2-allylamino-4-methylthiazol-5-yl)ethanone (3). The structures of newly synthesized compounds were confirmed by elemental analyses, spectral data, and chemical transformations. The synthesized compounds were evaluated in vitro for their antimicrobial activity against some human pathogenic bacterial and fungal strains. The compounds 7, 18, and 24 exhibited higher antibacterial activity with minimum inhibitory concentration (MIC) values ranging from (0.03–0.06 μg/mL) than ampicillin (MIC, 0.12 μg/mL) against Streptococcus pneumoniae. Whereas compounds 4, 22, and 24 revealed higher antifungal potency than amphotericin B against Aspergillus fumigatus. The structure and antimicrobial activity relationship was also discussed.

Following the identification through virtual screening of 4-(2,4-dimethyl-thiazol-5-yl)pyrimidin-2-ylamines as moderately potent inhibitors of cyclin-dependent kinase-2 (CDK2), a CDK inhibitor analogue program was initiated. The first aims were to optimize potency and to evaluate the cellular mode of action of lead candidate molecules. Here the synthetic chemistry, the structure-guided design approach, and the structure-activity relationships (SARs) that led to the discovery of 2-anilino-4-(thiazol-5-yl)pyrimidine ATP-antagonistic CDK2 inhibitors, many with very low nM Kis against CDK2, are reported. Furthermore, X-ray crystal structures of four representative analogues from our chemical series in complex with CDK2 are presented, and these structures are used to rationalize the observed biochemical SARs. Finally results are reported that show, using the most potent CDK2 inhibitor compound from the current series, that the observed antiproliferative and proapoptotic effects are consistent with cellular CDK2 and CDK9 inhibition.
