desmosterol

Desmosterol(24-Dehydrocholesterol) 是一种胆固醇生物合成中间体，抑制巨噬细胞炎症小体活化，防止血管炎症和动脉粥样硬化。

Azacosterol is a diaza derivative of cholesterol which acts as a hypocholesteremic agent by blocking delta-24-reductase causing accumulation of desmosterol. Azacosterol acts as an inhibitor of 24-dehydrocholesterol reductase (24-DHCR), preventing the formation of cholesterol from desmosterol. Although it primarily acts to inhibit 24-DHCR, the drug also inhibits other steps in cholesterol biosynthesis. The antifertility effects of the drug in birds are mediated by inhibition of steroid hormone production, steroid hormones being synthesized from cholesterol.
