Synthesis, antiproliferative screening, and molecular docking of some heterocycles derived from N-(1-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3-hydrazineyl-3-oxoprop-1-en-2-yl)benzamide

Abstract

Abstract The hydrazide derivative synthesized from oxazolone was employed as a key building block for the preparation of various N -acetyl, N -benzoyl, imidazole, tetrazine, pyrazole, and pyrazolopyrazole compounds. These target heterocycles were obtained by reacting the hydrazide with several carbon-based electrophilic reagents, including chloroacetyl chloride, benzoyl chloride, acetic anhydride, carbon disulfide, and pyrazole aldehyde. The synthesized compounds were evaluated for their antiproliferative activity against colon (HCT-116) and breast (MCF-7) cancer cell lines, which implied the more selective toxicity of these derivatives toward cancer cell lines rather than normal cell line (WI-38), signifying the safety of the tested compounds. Biological screening results demonstrated that compounds 5 , 8 , 9 , and 10 exhibited significant cytotoxic activity against both cell lines. Among molecular docking simulation, the ligand binding energies were like those of doxorubicin (as an anticancer drug) and RRC (as a CDK2 inhibitor), as the most interacting amino acids were common, proposing being CDK2 inhibitor. The superlative docking score was given by compound 9 (S= -9.5080 kcal/mol), which was higher than that of doxorubicin and co-crystallized ligand (RRC). This work may develop the innovative, highly effective agents against cancer in the future.
