A novel series of 2-(1-((1-substitutedphenyl-1H-1,2,3- triazol-4-yl)methoxy)ethyl)-1-((1-substituted phenyl- 1H-1,2,3-triazol-4-yl)methyl)-1H-benzo[d]imidazole (3a-j)derivatives was synthesized in moderate to high yields. The structures of all the synthesized compounds were characterized by 1HNMR, 13CNMR and Mass spectroscopic methods. The title compounds were screened for their anti-oxidant activity and anti-cancer activity. The cancer activity results reveal that the compounds 3j, 3b and 3f are showing promising activity and remaining compounds exhibited moderate activity against all the tested cancer cell lines. The anti-oxidant activity also shows that the compounds 3c and 3d have shown excellent activity and remaining compounds were also found to exhibit moderate activity against the test organisms employed.

: Background: Synthesis of a series of 2-(dichloromethyl)pyrazolo[1,5- a][1,3,5]triazines was carried out and evaluated in vitro for their anticancer activity against a panel of 60 cell lines derived from nine cancer types. The joint quantum-chemical and experimental study of the influence of the extended πconjugated phenyl substituents on the electron structure of the pyrazolo[1,5-a][1,3,5]triazines as Pharmacophores were performed. It is shown that the decrease in the barriers to the rotation of phenyl substituents in compounds 1-7 possibly leads to an increase in the anti-cancer activity, which is in agreement with the change in the parameter biological affinity ϕ0. Analysis of the S0 → S1 electronic transitions (π→π*) of the pyrazolo[1,5-a][1,3,5]triazines shows that an increase in their intensity correlates with anti-cancer activity. Thus, the introduction of phenyl substituents increases the likelihood of investigated pyrazolo[1,5-a][1,3,5]triazines interacting with protein molecules (Biomolecule) by the π stacking mechanism. In both methyl and phenyl derivatives of pyrazolo[1,5-a][1,3,5]triazines, the second electronic transition includes the n-MO (the level of the lone electron pair in two-coordinated nitrogen atoms). The highest intensity of the η→π* electronic transition is observed in pyrazolo[1,5-a][1,3,5]triazine with pyridine residue, which does not exhibit anti-cancer activity, but exhibits antiviral activity [13]. It can be assumed that the possibility of the formation of [Pharmacophore-Biomolecule] complex by hydrogen bonding ([H-B]) mechanism with protein molecules increases.
