Synthesis and in-vitro antioxidant and antitumor evaluation of novel pyrazole-based heterocycles

Abstract
Hydrazide-hydrazone, namely, N′-((5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)methylene)-2-cyanoacetohydrazide 3, was
utilized as a key starting material for the construction of a variety of novel heterocyclic moieties. The newly synthesized
compounds were characterized by elemental analyses and spectral data (IR, 1H-NMR, and mass spectra). Some of the newly
synthesized compounds were screened for their antitumor and antioxidant activities. The results showed clearly that compounds
6, 11, 13, 22, and 29 displayed promising in-vitro antitumor activity against two cell lines (HepG2 and MCF-7). Among these
compounds, compounds 13 and 29 exhibited the highest activity as antitumor agents. On the other hand, compounds 13, 22, and
29 exhibited the highest inhibitory antioxidant activity using ABTS method. While, in case of erythrocytes hemolysis, compounds
4, 13, and 29 proved to exhibit potent antioxidative activity as vitamin C. Meanwhile, compounds 6, 11, 16, 21, and 22
showed a remarkable promising activity. In light of the highest potency of our novel compounds in targeting both antitumor and
antioxidant activities, compounds 13 and 29 warrant persistent preclinical development as antitumor and antioxidant agents.
