Absolute structure of (3aS,5S,7aS,7bS,9aR,10R,12aR,12bS)-7b-hydroxy-4,4,7a,9a,12a-pentamethyl-10-[(2′R)-6-methylheptan-2-yl]-2,8,9-trioxooctadecahydrobenzo[d]indeno[4,5-b]azepin-5-yl acetate from 62-year-old crystals

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2019
The structure of the title compound, C32H51NO6, was determined from 62-year-old crystals at room temperature and refined with 100 K data in a monoclinic (C2) space group. This compound with a triterpenoid structure, now confirmed by this study, played an

Pubertal presentation in seven patients with congenital adrenal hyperplasia due to P450 Oxidoreductase deficiency [PDF]

open access: yes, 2010
Context: P450 oxidoreductase (POR) is a crucial electron donor to all microsomal P450 cytochrome (CYP) enzymes including 17α-hydroxylase (CYP17A1), 21-hydroxylase (CYP21A2) and P450 aromatase.

Ergosterol reduction impairs mitochondrial DNA maintenance in S. cerevisiae [PDF]

open access: yes, 2019
Sterols are essential lipids, involved in many biological processes. In Saccharomyces cerevisiae, the enzymes of the ergosterol biosynthetic pathway (Erg proteins) are localized in different cellular compartments.

Improvement of experimental testing and network training conditions with genome-wide microarrays for more accurate predictions of drug gene targets [PDF]

open access: yes, 2014
BACKGROUND: Genome-wide microarrays have been useful for predicting chemical-genetic interactions at the gene level. However, interpreting genome-wide microarray results can be overwhelming due to the vast output of gene expression data combined with off-

Ergosterol and Lanosterol from Aspergillus nidulans [PDF]

open access: yesMicrobiology, 1982
Ergosterol was identified as the major free sterol of Aspergillus nidulans by thin-layer chromatography, alumina column chromatography, gas-liquid chromatography, high-performance liquid chromatography, UV spectroscopy, proton magnetic resonance spectroscopy and mass spectral analysis.

Preparation and properties of a cell-free system from rat skin that catalyzes sterol biosynthesis

open access: yesJournal of Lipid Research, 1966
Homogenates of epidermis from rat skin were centrifuged at 10,000 · g for 20 min. The supernatant fraction (“whole homogenate”) catalyzed the demethylation of lanosterol (C30) to yield C27-sterols. The rate of reaction was measured by the rate of release

Effects of FoxO4 overexpression on cholesterol biosynthesis, triacylglycerol accumulation, and glucose uptake

open access: yesJournal of Lipid Research, 2010
The Forkhead transcription factors FoxO1, FoxO3a, and FoxO4 play a prominent role in regulating cell survival and cell cycle. Whereas FOXO1 was shown to mediate insulin sensitivity and adipocyte differentiation, the role of the transcription factor FoxO4

Plant oxidosqualene metabolism: cycloartenol synthase-dependent sterol biosynthesis in Nicotiana benthamiana. [PDF]

open access: yesPLoS ONE, 2014
The plant sterol pathway exhibits a major biosynthetic difference as compared with that of metazoans. The committed sterol precursor is the pentacyclic cycloartenol (9β,19-cyclolanost-24-en-3β-ol) and not lanosterol (lanosta-8,24-dien-3β-ol), as it was ...

Kajian in Silico Daun Sungkai (Peronema canescens) dalam Menghambat Enzim lanosterol 14-α demethylase Jamur Candida albicans

open access: yesIndonesian Journal of Pharmaceutical Education, 2023
Candida albicans (C. albicans) is a fungus that causes candidiasis. C. albicans has the enzyme Lanosterol 14- α demethylase. Lanosterol 14-α-demethylase has bioactivity in converting lanosterol to ergosterol, a special sterol found in fungal membranes,
