The article was written by Diao, Peng-Cheng; Lin, Wei-Yuan; Jian, Xie-Er; Li, Yan-Hong; You, Wen-Wei; Zhao, Pei-Liang. The article contains the following contents:
To develop novel CDK2 inhibitors as anticancer agents, a series of novel pyrimidine-based benzothiazole derivatives I (R = 4-(S(O)2NH2), 4-(piperidin-1-yl), 3-F, etc.) and II (R1 = H, F, Cl, Me, MeO; R2 = H, Me, F; R3 = Me, NH2) was designed and synthesized. Initial biol. evaluation demonstrated that some of target compounds displayed potent antitumor activity in vitro against five cancer cell lines. Especially, the analog II (R1 = F; R2 = H; R3 = NH2) exhibited approx. potency with AZD5438 toward four cells including HeLa, HCT116, PC-3, and MDA-MB-231 with IC50 values of 0.45, 0.70, 0.92, 1.80 μM, resp. More interestingly, the most highly active compound II (R1 = F; R2 = H; R3 = NH2) in this study also possessed promising CDK2/cyclin A2 inhibitory activities with IC50 values of 15.4 nM, which was almost 3-fold potent than pos. control AZD5438, and mol. docking studies revealed that the analog bound efficiently with the CDK2 binding site. Further studies indicated that compound II (R1 = F; R2 = H; R3 = NH2) could induce cell cycle arrest and apoptosis in a concentration-dependent manner. These observations suggest that pyrimidine-benzothiazole hybrids represent a new class of CDK2 inhibitors and well worth further investigation aiming to generate potential anticancer agents.6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Electric Literature of C7H5ClN2S) was used in this study.
6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9) belongs to thiazoles. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities.Electric Literature of C7H5ClN2SThiazoles can also be used as protected formyl groups, which can be released in later stages of complex natural product synthesis.
