L6H21是查尔酮的一种衍生物,是一种口服有效的MD-2(髓样分化因子2)抑制剂。它能够抑制巨噬细胞中的TLR4-NF-κB信号传导和NLRP3炎症小体的激活,并有效阻止乙醇与脂多糖诱导的RAW264.7细胞凋亡及线粒体损伤。此外,L6H21还能有效抑制乙醇与脂多糖共同作用引起的肝脂肪堆积和肝损伤。在糖尿病前期模型中,L6H21还表现出神经保护作用。
Stereoselective transformation of Baylis–Hillman adducts 1 into corresponding ( Z)-allyl chlorides 2 have been achieved by treatment with 2,4,6-trichloro [1,3,5]triazine and N, N-dimethyl formamide. This novel approach proceeds readily at room temperature within a few hours with excellent yields and stereoselectivity.
