Derivatives of salarin A, salarin C and tulearin A, three new cytotoxic sponge derived nitrogenous macrolides, were prepared and bio-evaluated as inhibitors of K562 leukemia cells. Interesting preliminary SAR (structure activity relationship) information was obtained from the products. The most sensitive functionalities were the 16,17-vinyl epoxide in both salarins, the triacylamino group in salarin A and the oxazole in salarin C (less sensitive). Regioselectivity of reactions was also found for tulearin A.
从海绵中提取的三种新的细胞毒性含氮大环内酯——salarin A、salarin C和tulearin A的衍生物,被制备并生物评价为K562白血病细胞的抑制剂。从这些产物中获得了有趣的初步的结构活性关系(SAR)信息。其中最敏感的功能基团包括salarin中16,17位的乙烯基环氧化物、salarin A中的三酰氨基团以及salarin C中的噁唑环(较不敏感)。tulearin A的反应还表现出区域选择性。
