Background: A wide range of pyrazole derivatives gained special attention due to their wide range of pharmacological activities especially the therapeutic activities. Many pharmacological drugs containing the pyrazole nucleus are known in the market. Method: The 3-phenyl-1H-pyrazol-5(4H)-one was the key starting compound for many heterocyclic reactions to produce substituted and fused pyrazole derivatives. Results: Antiproliferative activities of the produced compounds against six cancer cell lines A549, HT-29, MKN-45, U87MG, and SMMC-7721 and H460 were measured through which compounds showed high inhibitions. The most promising compounds were tested against tyrosine kinases (c-Kit, Flt-3, VEGFR-2, EGFR, and PDGFR). Structure-Activity Relationship (SAR) was rationalized by looking at the varying structural features of the molecules. In addition, the most active compounds were selected for Pim-1 inhibition. Conclusion: Thirty-nine pyrazole derivatives were synthesized. Nine of them 8b, 9, 12b, 12d, 14b, 15b, 18d, 18f, 19b, and 21d were the most active compounds toward the selected cancer cell lines. Compounds 12b, 14b, 18d, 18f, and 21d showed high inhibitions toward the tyrosine kinases, whereas compounds 14b, 18d, and 18f were the most potent inhibitors of Pim-1.

A series of 3-aryl-4-(arylhydrazono)-1H-pyrazol-5-one inhibitors of GSK3β was developed from a low molecular weight, highly ligand efficient screening hit 1. Hit-to-lead optimization led to a number of highly potent inhibitors, while maintaining the high ligand efficiency of the screening hit.
