A library of 1-benzyl-N-(2-(phenylamino)pyridin-3-yl)-1H-1,2,3-triazole-4-carboxamides (7a–al) have been designed, synthesized and screened for their anti-proliferative activity against some selected human cancer cell lines namely DU-145, A-549, MCF-7 and HeLa. Most of them have shown promising cytotoxicity against lung cancer cell line (A549), amongst them 7f was found to be the most potent anti-proliferative congener. Furthermore, 7f exhibited comparable tubulin polymerization inhibition (IC50 value 2.04 μM) to the standard E7010 (IC50 value 2.15 μM). Moreover, flow cytometric analysis revealed that this compound induced apoptosis via cell cycle arrest at G2/M phase in A549 cells. Induction of apoptosis was further observed by examining the mitochondrial membrane potential and was also confirmed by Hoechst staining as well as Annexin V-FITC assays. Furthermore, molecular docking studies indicated that compound 7f binds to the colchicine binding site of the β-tubulin. Thus, 7f exhibits anti-proliferative properties by inhibiting the tubulin polymerization through the binding at the colchicine active site and by induction of apoptosis.

Photochemical decomposition of 1-(2,5-dialkoxyphenyl)triazolopyridines 7a, 21 and 33 resulted in elimination of an alkoxy group to give the alkoxycarbolines 9a and 35 in addition to the expected dialkoxycarbolines.The carbolines having either a methoxy and an isopropoxy substituent 22, 34a and 34b or two methoxy groups 41 were oxidised with ceric ammonium nitrate to yield the α-, γ- or δ-carboline p-quinones.
