Compounds having α,β-unsaturated lactones display a variety of biological activities. Many research groups have tested both natural and unnatural α,β-unsaturated lactones for as-yet undiscovered biological properties. We synthesized α,β-unsaturated lactones with various substituents at the δ-position and studied their immunosuppressive effects, that is, the inhibition of Interleukin-2 (IL-2) production
具有α,β-不饱和内酯的化合物表现出多种生物活性。许多研究小组已经对天然和非天然α,β-不饱和内酯进行了测试,但尚未发现其生物学特性。我们合成了在δ位具有各种取代基的α,β-不饱和内酯,并研究了它们的免疫抑制作用,即抑制白介素2(IL-2)的产生。在合成的化合物中,苯并呋喃取代的α,β-不饱和内酯4h在Jurkat e6-1 T淋巴细胞(IC 50 = 66.9 nM)中表现出对IL-2产生的最佳抑制活性,而在10μM时无细胞毒性。结果表明4h 可能用作有效的免疫抑制剂,以及与IL-2相关的研究。
