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。

1-phenyl-1H-pyrazolo[3,4-d]pyrimidine derivatives with different substituents in the 4-position of the phenyl group and benzenesulfonamide moiety were synthesized and evaluated against Plasmodium falciparum. Six compounds exhibited activity in vitro against the chloroquine-resistant clone W2 with IC50 values ranging from 5.13 to 12.22 µM. The most active derivative with substituents R1 = F / R2 = CH3
合成了9个在苯基和苯磺酰胺部分的4-位具有不同取代基的1-苯基-1 H-吡唑并[3,4- d ]嘧啶衍生物,并评价了恶性疟原虫的药性。六种化合物在体外表现出对耐氯喹克隆W2的活性,IC 50值为5.13至12.22 µM。具有取代基R 1 = F / R 2 = CH 3的活性最高的衍生物的IC 50值为5.13 µM,IS值为62.90,高于对照药物磺胺多辛。因此,可以得出1 H -pyrazolo [3,4- d] pyrimidine系统有望作为进一步研究抗疟疾候选药物的原型。

1-phenyl-1H-pyrazolo[3,4-d]pyrimidine derivatives with different substituents at the 4-position of the phenyl group were synthesized. All compounds were initially tested at 100 µM concentration againstLeishmaniaamazonensis ARG (LaARG), showing inhibitory activity ranging from 36 to 74%. Two compounds, 1 (R=H) and 6 (R=CF3), showed arginase inhibition >70% and IC50 values of 12 µM and 47 µM, respectively.
