Modern pharmacological studies have demonstrated that C21 steroids are the main active compounds in XAPI. In this study, a sensitive and specific liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed and validated the first time for simultanenous determination of three ...

A NUMBER of C21 steroids characterized by the 17: 20-dihydroxy-20-methyl side-chain at C17 have been isolated from the urine of normal people 1,2 and from the urine of patients with adrenocortical hyper-plasia 3 or adrenocortical tumours 4 (see Table 1). The separation and identification ...
The formation of 16-androstenes and dehydroepiandrosterone from C2 1 steroids has been studied in boar testis microsomal preparations. The enzyme system concerned in the conversion of progesterone into 16-androstenes was found predominantly in the microsomal fraction of boar testis and its activity is...

There was a highly significant difference in the amounts of GnRHa released into the bloodstream by the two methods of administration on day 4. However, this was not matched by significant differences in the concentrations of any of the steroids. 展开 ...
C21 steroidantiepileptic effectzebrafishIn order to discover more natural products possessing potentially antiepileptic activities, three C21 steroids, including a new one, characterized as caudatin-3-O-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside (1), ...
