| Application | 3α-Hydroxysteroid dehydrogenase (3α-HSD) plays a crucial physiological role in vivo, responsible for inactivating circulating steroid hormones and regulating their activity in target tissues (especially the liver), thus participating in steroid hormone clearance. In vitro, purified 3α-HSD is widely used as a biochemical reagent, primarily for clinical diagnosis and research. For example, it can be used to determine enzyme activity levels for quantitative analysis of bile acid or certain steroid hormone levels. Furthermore, it is an important tool for studying the mechanisms of action of nonsteroidal anti-inflammatory drugs (NSAIDs) and progestins, as these drugs are often found to be inhibitors of this enzyme. |
