combination of modified rings A and C increases the potency by about 10 000 times compared with the lead compound, 3-oxooleana-1,12-dien-28-oic acid (8) (IC(50) = 1 microM level). The selected oleanane triterpenoid, CDDO (26), was found to be a potent, multifunctional agent in various in vitro assays and to show antiinflammatory activity against thioglycollate-interferon-gamma-induced mouse peritonitis
我们已经设计和合成了16种新的含有各种修饰的环C的新的齐墩果酸和urs-1-en-3-one三萜类化合物作为潜在的抗炎药和癌症化学预防剂,并评估了它们对小鼠巨噬细胞中γ-干扰素诱导的一氧化氮产生的抑制作用。 。该研究表明,与原始的12-烯相比,C环中的9(11)-en-12-one和12-en-11-one官能团的效价提高了约2-10倍。随后,我们设计并合成了A环C-2处具有腈基和羧基且具有9(11)-en-12-one和12-en- C环中具有11个官能团。其中,我们发现,甲基2-氰基-3,12-二氧代油橄榄-1,9(11)-二烯-28-酸酯(25),2-氰基-3,12- dioxooleana-1,9(11)-dien-28-oic acid(CDDO)(26)和甲基2-羧基-3,12-dioxooleana-1,9(11)-dien-28-oate(29)具有极高的效价(IC(50)=
