A series of 3-aryl-4-(arylhydrazono)-1H-pyrazol-5-one inhibitors of GSK3 beta 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. (C) 2010 Elsevier Ltd. All rights reserved.

A series of new pyrazolone and pyrazole derivatives with expected antifungicidal activity have been prepared through the reactions 3‐phenyl‐1‐H‐pyrazol‐5(4H)‐one (3) and 4‐(dimethylaminomethylene)‐3‐phenyl‐1H‐pyrazol‐5(4H)‐one (5) with a variety of electrophilic reagents and nucleophilic reagents. The newly synthesized compounds were characterized by IR, 1H NMR, 13C NMR and mass spectral studies.
通过3-苯基-1- H-吡唑-5(4 H)-一(3)和4-(二甲基氨基亚甲基)-3-苯基-1的反应制备了一系列具有预期抗真菌活性的吡唑啉酮和吡唑衍生物H-吡唑-5(4 H)-一(5)与各种亲电试剂和亲核试剂。通过IR,1 H NMR,13 C NMR和质谱研究表征了新合成的化合物。

3a and 3i showed comparable cytotoxic activity with IC50 values of 1.22 and 1.24 μM compared to the reference drugs (IC50 = 0.932, 1.13 μM). Compound 3i was found to be the most effective VEGFR-2 inhibitor using in vitro testing of the synthesized compounds, with nearly 3-fold higher activity than Sorafenib (30 nM), with IC50 8.93 nM. Compound 3i significantly stimulated total apoptotic prostate cancer
