regioisomers of (R)- and (S)-hydroxypalmitic acids (HPAs) and hydroxystearic acids (HSAs), whose biological activity has not been tested so far, were studied for their antiproliferative activities. The unsaturation of the long chain, as well as an odd-numbered (C17) fatty acid chain, led to reduced activity, while the new 6-(S)-HPA regioisomer was identified as exhibiting potent antiproliferative activity
羟基脂肪酸 (HFA) 构成一类脂质,其特征是在脂肪长链上存在羟基。本研究旨在扩展我们对 HFA 生物活性的见解,同时也引入了不对称合成不饱和和饱和 HFA 的新方法。同时,我们之前建立的程序被用于生成新的 HFA 区域异构体。采用有机催化步骤合成手性末端环氧化物,其通过炔基化或 Grignard 试剂产生不饱和或饱和的手性仲醇,并最终产生 HFA。首次合成了 7-(S)-羟基油酸 (7SHOA)、7-(S)-羟基棕榈油酸 (7SHPOA) 和 7-(R)- 和 (S)-羟基人造石酸 (7HMA),并与 (R)- 和 (S)-羟基棕榈酸 (HPA) 和羟基硬脂酸 (HSA) 的区域异构体一起研究了其抗增殖活性。长链的不饱和以及奇数 (C17) 脂肪酸链导致活性降低,而新的 6-(S)-HPA 区域异构体被鉴定为在 A549 细胞中表现出有效的抗增殖活性。6SHPA 诱导 A549 细胞中组蛋白
