Ipomoeassin F 是一种高效且具有选择性的内质网(ER)蛋白转位抑制剂,它通过作用于ER膜上的Sec61复合物(Sec61α)的成孔亚基来实现其功能。此化合物能特异性抑制SARS-CoV-2蛋白在ER膜上的转位,同时阻碍分泌蛋白和I型跨膜蛋白(TMP)的ER转运,但对III型TMP的转运不产生影响。
Nimbin is an anti-pyretic, can be used to treat arthritis, hypoglycaemia, peptic ulcers, anti-secretory activity, and it can also be used as an antibiotic. Nimbin requires to elicit a 50% inhibition of this steroid hydroxylase activity in the three insect
Variabilin, a novel inhibitor of human platelet aggregation, it is a potent RGD (Arg-Gly-Asp)-containing antagonist of the fibrinogen receptor glycoprotein IIb-IIIa (GPIIb-IIIa; αIIbβ3) and the vitronectin receptor αvβ3.Variabilin is also an antimicrobial furanosesterterpene. Variabilin is an inhibitor of human secretory and cytosolic phospholipase A2 (PLA2) activities that controls eicosanoid production in vitro and in vivo, inhibits neutrophil degranulation and superoxide generation in vitro and shows anti-inflammatory activity after topical or p.o. administration to mice.
