Six series of pyrrolo[2,3-d]pyrimidine and pyrazolo[3,4-d]pyrimidine derivatives bearing 1,2,3-triazole moiety were designed and synthesized, and some bio-evaluation was also carried out. As a result, four points can be summarized: Firstly, some of compounds exhibited excellent cytotoxicity activity and selectivity with the IC50 values in single-digit μm level. In particular, the most promising compound 16d showed equal activity to lead compound foretinib against A549, HepG2, and MCF-7 cell lines, with the IC50 values of 4.79?±?0.82, 2.03?±?0.39, and 2.90?±?0.43?μm, respectively. Secondly, the SARs and docking studies indicated that the in vitro antitumor activity of pyrrolo[2,3-d]pyrimidine derivatives bearing 1,2,3-triazole moiety was superior to the pyrazolo[3,4-d]pyrimidine derivatives bearing 1,2,3-triazole moiety. Thirdly, three selected compounds (16d, 18d, and 20d) were further evaluated for inhibitory activity against the c-Met kinase, and the 16d could inhibit the c-Met kinase selectively by experiments of enzyme-based selectivity. What is more, 16d could induce apoptosis of HepG2 cells and inhibitor the cell cycle of HepG2 on G2/M phase by acridine orange staining and cell cycle experiments, respectively.

A new series of 3-(5-methyl-1-phenyl-1H-4-pyrazolyl)-6-(5-methyl-1-aryl-1H-1,2,3-triazol-4-yl)[1,2,4]triazolo [3,4-b][1,3,4]thiadiazoles 12a-j have been prepared and assayed for their antibacterial activity against human pathogenic Gram-positive bacteria viz., Staphylococcus aureus, Bacillus subtilis and Gram-negative Escherichia coli. Among the screened compounds 12b, 12c and 12f, in which phenyl ring of triazole moiety bear 4-chloro, 4-nitro and 4-fluoro substituents respectively, showed high activity against all the micro-organisms employed. The activities of these compounds are almost equal to the standards.

A series of novel pyrrolo[2,3-b]pyridine derivatives bearing 1,2,3-triazole moiety were designed, synthesized, and evaluated for their c-Met kinase inhibitory activities and antiproliferative activities against 4 cancer cell lines (HT-29, A549, MCF-7, and PC-3) in vitro. Most compounds showed moderate to excellent potency, with the most promising analog 34 showing a c-Met IC50value of 1.68?nM. Structure–activity relationship studies indicated that electron-withdrawing groups (X?=?CF3, R1?=?F, R2?=?4-F) were required to decrease the higher electron density on the 5-atom linker to a proper degree to improve the inhibitory activity.

Page/Page column 77, (2009/10/18)
The present disclosure relates to triazoles and processes for their preparation. The processes involve a target-guided synthesis approach, whereby an alkyne and an azide are reacted in the presence of a biological target protein, a Bcl-2 family protein, to form the triazole.
