compounds, marine natural products have been increasingly screened as candidates for developing new drugs. Among the several marine products and metabolites, (+)-Harzialactone A has drawn considerable attention for its antitumor and antileishmanial activity. In this work a chemoenzymatic approach has been implemented for the preparation of the marine metabolite (+)-Harzialactone A. The synthesis involved
作为生物活性化合物的丰富来源,海洋天然产物越来越多地被筛选为开发新药的候选者。在多种海洋产品和代谢物中,( + )-Harzialactone A 因其抗肿瘤和抗利什曼病活性而受到广泛关注。在这项工作中,采用化学酶方法来制备海洋代谢物 ( + )-Harzialactone A。该合成涉及前手性酮 4-氧代-5-苯基戊酸或相应酯的立体选择性、生物催化还原,所有这些均生成通过化学反应。研究了一系列不同的混杂氧化还原酶(野生型和工程化的)和不同的微生物菌株来介导生物转化。为了增强生物还原性能,经过共溶剂和共底物研究后,NADES(盐酸胆碱-葡萄糖)和 ADH442 存在下的T. molischiana被认为是最有前途的生物催化剂,从而能够获得 ( S )-对映体具有出色的ee (分别为 97% 到 > 99%)和良好到优秀的转化率(分别为 88% 到 80%)。本研究的成功尝试为( + )-Harzialactone
