  Novel Angular Benzophenazines:  Dual Topoisomerase I and Topoisomerase II Inhibitors as Potential Anticancer Agents

  摘要：

  A series of substituted angular benzophenazines were prepared using a new synthetic route via a novel regiocontrolled condensation of 1,2-naphthoquinones and 2,3-diaminobenzoic acids. The synthesis and biological activity of this new series of substituted 8,9-benzo[a]phenazine carboxamide systems are described. The analogues were evaluated against the H69 parental human small cell lung carcinoma cell line and H69/LX4 resistant cell line which overexpresses P-glycoprotein. Selected analogues were evaluated against the COR-L23-parental human non small cell lung carcinoma cell line and the COR-L23/R resistant cell line which overexpresses multidrug resistance protein. This series of novel angular benzophenazines were potent cytotoxic agents in these cell lines and may be able to circumvent multidrug resistance mechanisms which result in the lack of efficacy of many drugs in cancer chemotherapy. These compounds show dual inhibition of topoisomerase I and topoisomerase II and thus target two key enzymes responsible for the topology of DNA that are active at different points in the cell cycle. The introduction of chirality into the carboxamide side chain of these novel benzophenazine carboxamides has resulted in the discovery of a potent enantiospecific series of cytotoxic agents, exemplified by 4-methoxy-benzo[a]phenazine-11-carboxylic acid (2-(dimethylamino)-1-(R)methyl-ethyl)-amide, XR11576 ((R)-4j"). In vivo activity has been demonstrated for 4-methoxy-benzo[a]phenazine-11-carboxylic acid (2-(dimethylamino)-1-(R)-methyl-ethyl)-amide, XR11576, after intravenous administration to female mice, and this compound has been selected as a development candidate for further evaluation.

  通过新分离的玉米曲霉 ZJUT ZQ013 菌株生物生产 l-2-氨基丁酸

  摘要：

  摘要l-2-氨基丁酸（l-ABA）是一种非天然氨基酸，是几种重要药物的关键中间体。虽然已经开发了一些制备纯手性l-ABA的方法，但由于加入了一些昂贵的催化剂或辅酶，仍存在催化效率低、步骤繁琐和成本高的缺点。在此，我们结合化学和生物学方法，发现了一种新分离的玉米曲霉 ZJUT ZQ013 菌株，该菌株含有微生物脂肪酶，可用于分解外消旋甲基 N-Boc-2-氨基丁酸以产生具有高对映选择性（ees > 99.9）的 l-ABA %，E = 257）。此外，随后的克级实验证实，A. tamarii ZJUT ZQ013 是一种有效制备光学纯酸的有吸引力的生物催化剂。
