Multi-step Synthesis of Novel Pyrazole Derivatives as Anticancer Agents

The attractiveness of pyrazole and its derivatives is increasing because of their numerous potential pharmacological applications. A novel series of pyrazole hybrid compounds (6A-6L) has been synthesized, and all the intermediates and the final products were characterized by 1H NMR, IR, and mass spectrometry. Pyrazole derivatives were screened for their anticancer activity against the NCI-60 cell lines, and grouped into nine different subpanels. In-vitro anticancer studies of the targeted compounds showed that the compounds 6C, 6D, 6F, 6I, and 6J showed potent anticancer activity against renal cancer, ovarian cancer, melanoma, and leukemia cancer.{GRAPHIACAL ABSTRACT}
