Cyclin-dependent kinases (CDKs) are a family of Ser/Thr kinases involved in cell cycle and transcriptional regulation. CDK9 regulates transcriptional elongation and this unique property has made it a potential target for several diseases. Due to the conserved ATP binding site, designing selective CDK9 inhibitors has been challenging. Here we report our continued efforts in the optimization of 2,4,5-tri-substituted pyrimidine compounds as potent and selective CDK9 inhibitors. The most selective compound 30m was >100-fold selective for CDK9 over CDK1 and CDK2. These compounds showed broad anti-proliferative activities in various solid tumour cell lines and patient-derived chronic lymphocytic leukaemia (CLL) cells. Decreased phosphorylation of the carboxyl terminal domain (CTD) of RNAPII at Ser-2 and down-regulation of anti-apoptotic protein Mcl-1 were confirmed in both the ovarian cancer model A2780 and patient-derived CLL cells.

Paragraph 0022, (2017/10/05)
The invention discloses a method for preparing such CDK inhibitors, will be single-methyl thiourea and 1 - N monochloride reaction, 4 - dimethylthiazole - 2 - amine, by bromo reaction to obtain 5 - bromo - N, 4 - dimethylthiazole - 2 - amine, under the action of the catalyst after the with the borate to obtain aromatic borate intermediates; aromatic borate ester intermediate with 2, 4 - dichloro - 5 fluoro uracil in the noble metal catalytic under suzuki coupling reaction to obtain the coupling product to continue after the Buchwald - Hartwig with the aromatic amine in the reaction, ultimately to obtain the target product.

A new synthesis of 2-aminothiazoles and 5H-thiazolo[ 3,2-α]pyrimidin- 5-ones was developed as a domino alkylation-cyclization reaction of propargyl bromides with thioureas and thiopyrimidinones, respectively. Domino reactions were performed under microwave irradiation leading to desired compounds in a few minutes and high yields. Georg Thieme Verlag Stuttgart.
