A series of novel N-methyl-substituted pyrazole carboxamide (10–17) and dicarboxamide derivatives (18–21) were efficiently obtained by the reaction of pyrazole-3-carboxylic acids (4,5) and pyrazole-3,4-dicarboxylic acid (8) with several aromatic and heteroaromatic sulfonamides. Synthesized sulfonamide derivatives were characterized using 1H NMR, 13C NMR, FT-IR, mass spectroscopy techniques. Antiproliferative activities of synthesized molecules were evaluated against the human cervical cancer cell line (HeLa) using the xCELLigence system (Real-Time Analyzer). According to the antiproliferative activity results, compound 16 showed the highest activity among the synthesized compounds with 64.10%, while starting compound 4 showed the highest at all with 80.82%. Graphical abstract: The methyl substituted pyrazole carboxylic (4) and carboxamide (16) derivatives with antiproliferative activities with 80.82% and 64.10%, respectively, and compound 13 with moderate activity (61.26%) against the human cervical cancer cell line could be a potential lead compounds for developing novel anticancer agents.
