series of novel pyrazolo[3,4-d]pyrimidin-4-one derivatives were synthesized and evaluated for their anti-phosphodiesterase-5 (PDE-5) activity. A total of 28 compounds, containing alkyl and aryl groups at the 1-N and 3-C positions on the pyrazole ring, and also bearing different alkyl substituents on the piperazine ring were synthesized. Four compounds (4d, 5d, 6d, and 5o) were found to have better

The present invention provides compounds of Formula (I) as defined in the specification and compositions comprising any of such novel compounds. These compounds are endothelial lipase inhibitors which may be used medicaments.
The compound class of 1H-pyrazolo[3,4-d]pyrimidines was identified using HTS as very potent inhibitors of facilitated glucose transporter 1 (GLUT1). Extensive structure–activity relationship studies (SAR) of each ringsystem of the molecular framework was established revealing essential structural motives (i.e., ortho-methoxy substituted benzene, piperazine and pyrimidine). The selectivity against
使用HTS将1 H-吡唑并[3,4- d ]嘧啶类化合物鉴定为促进葡萄糖转运蛋白1(GLUT1)的非常有效的抑制剂。建立了分子框架每个环系统的广泛结构-活性关系研究(SAR),揭示了必要的结构动机(即,邻甲氧基取代的苯,哌嗪和嘧啶)。对GLUT2的选择性非常好,并且最初的体外和体内药代动力学(PK)研究令人鼓舞。
