Concept
Steroidogenesis inhibitor
Summary
A steroidogenesis inhibitor, also known as a steroid biosynthesis inhibitor, is a type of drug which inhibits one or more of the enzymes that are involved in the process of steroidogenesis, the biosynthesis of endogenous steroids and steroid hormones. They may inhibit the production of cholesterol and other sterols, sex steroids such as androgens, estrogens, and progestogens, corticosteroids such as glucocorticoids and mineralocorticoids, and neurosteroids. They are used in the treatment of a variety of medical conditions that depend on endogenous steroids.
Steroidogenesis inhibitors are analogous in effect and use to antigonadotropins (which specifically inhibit gonadal sex steroid production), but work via a different mechanism of action; whereas antigonadotropins suppress gonadal production of sex steroids by effecting negative feedback on and thereby suppressing the hypothalamic–pituitary–gonadal axis, steroidogenesis inhibitors directly inhibit the enzymatic biosynthesis of steroids.
HMG-CoA reductase (HMGCR) inhibitors, also known as statins, prevent the conversion of () into mevalonic acid, a relatively early step in the biosynthesis of cholesterol from acetyl coenzyme A (acetyl-CoA), and thereby decrease cholesterol levels. Examples of statins include atorvastatin, lovastatin, rosuvastatin, and simvastatin. They are used in the treatment of hypercholesterolemia for the purpose of lowering the risk of atherosclerosis-related cardiovascular disease.
Farnesyl pyrophosphate synthase (FPPS) inhibitors prevent the conversion of isopentenyl pyrophosphate (IPP) into farnesyl pyrophosphate (FPP), a mid-range step in the biosynthesis of cholesterol from acetyl-CoA, and thereby inhibit cholesterol production. They notably do not significantly lower circulating levels of cholesterol however, and hence, unlike statins, are not suitable for the treatment of hypercholesterolemia. The main examples of FPPS inhibitors are nitrogenous bisphosphonates such as alendronate, ibandronate, pamidronate, risedronate, and zoledronate, which are used in the treatment of osteoporosis.
