We identified a new radical scavenger, 10T024A (C(15)H(12)N(2)O(4)), from a culture of the Streptomyces sp. Spectroscopic elucidation indicated that this compound is a new phenazine derivative. 10T024A showed radical-scavenging activity with an ED(50) of 125 µM. Moreover, it showed prostaglandin D(2) (PGD(2)) and leukotriene B(4) (LTB(4)) release suppressive activity in rat basophilic leukemia (RBL-2H3)
我们从链霉菌属菌种的培养物中鉴定了一种新的自由基清除剂10T024A(C(15)H(12)N(2)O(4))。光谱分析表明该化合物是新的吩嗪衍生物。10T024A表现出自由基清除活性,ED(50)为125 µM。此外,它在大鼠嗜碱性白血病(RBL-2H3)细胞中的前列腺素D(2)(PGD(2))和白三烯B(4)(LTB(4))释放抑制活性,IC(50)为8 µM,分别为10 µM。
