The synthesis of 2-arylidene 6-(2-aryl-2-oxoethoxy)benzofuran-3-one derivatives was reported and selected compounds were determined for their anticancer activity evaluation in National Cancer Institute NCI, USA according to the drug screening protocol of the institute against approximately 60 tumor cell lines derived from nine cancer diseases. Compound 3r, namely 2-(4- chlorobenzylidene)-6-[2-(4-m

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)。
Design and synthesis of a novel “turn-on” fluorescent probe based on benzofuran-3(2H)-one for detection of hydrazine in water samples and biological systems
of the ecological environment but also supplied important information for the system optimization of other ecological environment detectors. In addition, HZ could monitor endogenous and exogenous hydrazine in MCF-7 cells successfully, which demonstrated its potential for practical application in complex biological systems.
