inhibited PfGSK-3, with four of these compounds exhibiting IC50 values in the sub-micromolar range (0.00048–0.440 µM). Evaluation of the structure-activity relationships required for PfGSK-3 selective inhibition indicated that a C6-OCH3 substitution on ring A is preferred, while the effect of the ring B substituent on activity, in decreasing order is: C4′-CN > C4′-F > C3′-OCH3 > C3′,4′-diCl.

恶性疟原虫糖原合酶激酶-3 ( Pf GSK-3) 已被确定为开发针对多药耐药疟疾的新型药物的潜在靶标。合成并评估了一系列基于苯并呋喃的化合物作为重组表达和纯化的Pf GSK-3 和人糖原合酶激酶-3 β ( Hs GSK-3β) 的抑制剂。在该系列中,五种化合物(5k、5m、5p、5r、5s)优先抑制Pf GSK-3,其中四种化合物表现出 IC 50亚微摩尔范围内的值 (0.00048–0.440 µM)。对Pf GSK-3 选择性抑制所需的构效关系的评估表明,A 环上的 C6-OCH 3取代是优选的,而 B 环取代基对活性的影响按降序排列为:C4'-CN > C4'-F > C3'-OCH 3 > C3',4'-diCl。迄今为止,Pf GSK-3 抑制剂的开发仅限于 4-苯基噻吩并[2,3- b ]吡啶类。基于查尔酮的支架,例如本文所述的苯并呋喃,是有希望的新命中,可用于未来设计Pf
