drugs. In this study, a series of new benzofuro[3,2-b]pyridin-7-ols were designed and synthesized for the first time and screened for their topoisomerase I and II inhibitory and antiproliferative activity. Structure-activity relationships revealed the position of ortho- and para-hydroxyl group at 2-phenyl ring, and meta-hydroxyl group at 4-phenyl ring of benzofuro[3,2-b]pyridin-7-ol are important for potent
人类DNA拓扑异构酶已成为开发更有效的抗癌药物的诱人靶标。在这项研究中,首次设计和合成了一系列新的苯并呋喃[3,2 - b ]吡啶-7-ol,并筛选了它们对拓扑异构酶I和II的抑制和抗增殖活性。构效关系揭示了苯并呋喃[3,2 - b ]吡啶-7-ol在2-苯基环上的邻羟基和对羟基位置以及在4-苯基环上的间羟基对于有效的和重要的活性很重要。选择性的topo II抑制活性。化合物11表现出最具选择性和效力的topo II抑制作用(在100 µM时抑制100%)和最强的抗增殖活性(IC50 = 0.86 µM)。
