Thus, it is a perfect framework for the synthesis of novel C–N, C–C bond formations like 5-substituted-1-benzyl-1Hpyrrolo[ 2,3-b]pyridines (3), 2-(1H-pyrrolo[2,3-b]pyridin-5-yl)phenol (5) and screened for their anticancer activity. The synthesized compounds were characterized by 1H NMR, 13C NMR, IR, mass spectral techniques and elemental analysis. The outcomes of these compounds 2,6-difluorobenzylpyrrolidin- 1H-pyrrolo[2,3-b]pyridine, 2,6-difluorobenzyl-N,N-dimethyl-1H-pyrrolo[2,3-b]-pyridin-5-amine had a signicant anticancer activity against human cervical cancer cell line (Hela) with IC50 4.8, 9.7 μg/mL and whereas pyrrolo[2,3-b]pyridin-5-phenol, pyrrolo[2,3-b]pyridin-5-vinylphenol are active against human breast cancer cell line (MCF-7) with IC50 8.1, 3.2 μg/mL, respectively.

Objective: Encouraged by these results, these analogues 4-(((7-amino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazol-6-yl)methyl)amino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-ones 8 have been synthesized and their inhibitory potential activity against different bacterial microorganisms and cancer cell lines was discussed. Methods: All the synthesized final scaffolds were characterized by 1H NMR, 13C NMR, IR, mass and elemental analysis. All the synthesized 1,2,4–triazole linked to pyrazole compounds were evaluated for their antimicrobial sensitivity by using the agar dilution technique. The anticancer activity of these compounds has been assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenylt...
