  Discovery of mixed type thymidine phosphorylase inhibitors endowed with antiangiogenic properties: Synthesis, pharmacological evaluation and molecular docking study of 2-thioxo-pyrazolo[1,5-a][1,3,5]triazin-4-ones. Part II

  摘要：

  In our drug discovery program, a series of 2-thioxo-pyrazolo[1,5-a][1,3,5]triazin-4-ones were designed, synthesized and evaluated for their TP inhibitory potential. All the synthesized analogues conferred a varying degree of TP inhibitory activity, comparable or better than positive control, 7-deazaxanthine (7-DX, 2) (IC50 value = 42.63 mu M). A systematic approach to the lead optimization identified compounds 3c and 4a as the most promising TP inhibitors, exhibiting mixed mode of enzyme inhibition. Moreover, selected compounds demonstrated the ability to attenuate the expression of the angiogenic markers (viz. MMP-9 and VEGF) in MDA-MB-231 cells at sublethal concentrations. In addition, molecular docking studies revealed the plausible binding orientation of these inhibitors towards TP, which was in accordance with the experimental results. Taken as a whole, these compounds would constitute a new direction for the design of novel TP inhibitors with promising antiangiogenic properties. (C) 2014 Elsevier Masson SAS. All rights reserved.

  The Synthesis of Some Derivatives Based on the 4-Benzyl-1H-pyrazole-3,5-diamine Core

  摘要：

  The three-step synthesis of 4-benzyl-1H-pyrazole-3,5-diamines 2 from commercially available aldehydes 3 is given. The Knoevenagel condensation was utilized to assemble the initial carbon framework, resulting in the benzylidenemalononitriles 4 which were directly transformed by the reduction of the electron deficient C=C bond to benzylmalononitriles 5. Subsequent cycloaddition of hydrazine with 5 afforded the desired pyrazoles 2. Due to the high similarity with 4-arylazo-1H-pyrazole-3,5-diamines, the biological activities of the 4-benzyl-1H-pyrazole-3,5-diamines 2 were evaluated while focusing on the inhibition of cyclin-dependent kinases (CDKs), but no significant results were obtained.
