چکیده
The title compound, C(30)H(50)O(3), which was isolated from a marine endophytic fungus, is a new friedelan derivative. The mol-ecule contains five six-membered rings, which exhibit boat (ring A), distorted boat (ring B) and chair (rings C-E) conformations. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds, which link neighbouring mol-ecules into 12-membered rings.

Data on the uptake and metabolism of testosterone by the common mussel, Mytilus spp.
This article provides data in support of the research article entitled "Rapid uptake, biotransformation, esterification and lack of depuration of testosterone and its metabolites by the common mussel, Mytilus spp." (T.I. Schwarz, I. Katsiadaki, B.H. Maskrey, A.P. Scott, 2017) [1]. The uptake of tritiated testosterone (T) from water by mussels is presented. The two main radioactive peaks formed ...
متن کاملAnnexin A5 regulates Leydig cell testosterone production via ERK1/2 pathway
This study was to investigate the effect of annexin A5 on testosterone secretion from primary rat Leydig cells and the underlying mechanisms. Isolated rat Leydig cells were treated with annexin A5. Testosterone production was detected by chemiluminescence assay. The protein and mRNA of Steroidogenic acute regulatory (StAR), P450scc, 3β-hydroxysteroid dehydrogenase (3β-HSD), 17β-hydroxysteroid d...
متن کاملEffects of genistein and equol on human and rat testicular 3β-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase 3 activities
The objective of the present study was to investigate the effects of genistein and equol on 3β-hydroxysteroid dehydrogenase (3β-HSD) and 17β-hydroxysteroid dehydrogenase 3 (17β-HSD3) in human and rat testis microsomes. These enzymes (3β-HSD and 17β-HSD3), along with two others (cytochrome P450 side-chain cleavage enzyme and cytochrome P450 17α-hydroxylase/17-20 lyase), catalyze the reactions th...
متن کاملInhibition of human and rat testicular steroidogenic enzyme activities by bisphenol A.
Bisphenol A (BPA) is a potential endocrine disruptor. It has been shown that it reduces serum testosterone level in rodents after exposure. However, the mechanism is unclear. The object of the present study is to investigate the effects of BPA on human and rat steroidogenic enzymes including P450 17α-hydroxylase/17,20-lyase (CYP17A1), 3β-hydroxysteroid dehydrogenase (3β-HSD) and 17β-hydroxyster...
متن کاملSterol 3β-glucosyltransferase biocatalysts with a range of selectivities, including selectivity for testosterone.
The main objectives of this work were to characterise a range of purified recombinant sterol 3β-glucosyltransferases and show that rational sampling of the diversity that exists within sterol 3β-glucosyltransferase sequence space can result in a range of enzyme selectivities. In our study the catalytically active domain of the Saccharomyces cerevisiae 3β-glucosyltransferase was used to mine put...
