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.

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.

scheme or table, p. 91 - 94 (2009/10/02)
The N,N′-bis[1-(4-methoxyphenyl)-5-methyl-1H-1,2,3-triazole-4- carbonyl]hydrazide 6 was synthesized from aryl triazole acids and its structure is established by MS, IR, and 1H NMR spectral data. Compound 6, C22H22N8O4, Mr = 462.48, crystallizes in the monoclinic space group P2(1)/c with unit cell parameters a = 15.3451(8), b = 8.6486(4), c = 16.8502(9) A, α = 90.00, β = 95.731(2), γ = 90.00°, V = 2225.1(2) A3, Z = 4, and Dx = 1.381 mg m-3. The final R was 0.0450. The four aromatic rings are close to linear because of N???H-N hydrogen bonds.
