DNA gyrase of Mycobacterium tuberculosis (MTB) is a type II topoisomerase and is a well-established and validated target for the development of novel therapeutics. By adapting the medium throughput screening approach, we present the discovery and optimization of ethyl 5-(piperazin-1-yl) benzofuran-2-carboxylate series of mycobacterial DNA gyraseB inhibitors, selected from Birla Institute of Technology
结核分枝杆菌(MTB)的DNA促旋酶是II型拓扑异构酶,是开发新型疗法的公认且有效的靶标。通过适应中等通量筛选方法,我们提出了分枝杆菌DNA gyraseB抑制剂的5-(哌嗪-1-基)苯并呋喃-2-羧酸乙酯乙酯系列的发现和优化,选自Birla技术和科学研究院(BITS)数据库化学约3000个分子的文库。对这些化合物的生物活性进行了测试;化合物22成为对耻垢分枝杆菌的活性最高的有效铅,IC 50为3.2±0.15μMDNA gyraseB酶和0.81±0.24μM的MTB超螺旋活性。随后,使用差示扫描荧光法进一步表征最具活性的化合物与DNA促旋酶B酶的结合及其热稳定性。
