描述信息

Etiocholanolone is the 5-beta-reduced isomer of androsterone. Etiocholanolone is a major metabolite of testosterone and androstenedione in many mammalian species including humans. It is excreted in the urine and is androgenically inactive. Classified a ketosteroid, it causes fever (it is a pyrogen), immunostimulation and leukocytosis. The pyrogenic effect of Etiocholanolone has been shown to be due to the release of interleukin-1 (IL-1) from the leukocytes that are mobilized in response to its production or injection. Etiocholanolone has anticonvulsant activity and may be an endogenous modulator of seizure susceptibility. Significantly increased values of etiocholanolone (along with testoterone and androsterone) an be detected in the urine of men with androgenic alopecia (male pattern baldness). [HMDB]
