19-Noretiocholanolone

Description:

19-Noretiocholanolone, with the CAS number 33036-33-8, is a synthetic steroid that is a derivative of the natural steroid etiocholanolone. It is characterized by its structural modifications, specifically the absence of a methyl group at the 19th carbon position, which distinguishes it from its parent compound. This alteration affects its biological activity and metabolic pathways. 19-Noretiocholanolone is often studied in the context of its potential use in doping in sports, as it can influence anabolic processes and muscle growth. The compound is typically analyzed using techniques such as gas chromatography-mass spectrometry (GC-MS) for detection in biological samples. Its pharmacological effects, like other anabolic steroids, can include increased protein synthesis and muscle mass, but it may also carry risks of side effects, including hormonal imbalances and cardiovascular issues. As with many steroids, its use is regulated in many countries, particularly in competitive sports.
