A computational mechanistic study of CH hydroxylation with mononuclear copper-oxygen complexes [PDF]

open access: yes, 2022
We present a computational study of methane hydroxylation by oxygen-bound monocopper complexes with the twin goals of resolving the active site identity and preferred mechanism of CH activation.

The hydroxylation of ?5-androstenes by Cephalosporium aphidicola

open access: yes, 1998
Whereas the major hydroxylation product of 3?-hydroxy-5?-androstan-17-one by Cephalosporium aphidicola is the 11?-alcohol, the presence of a ?5-double bond in the substrate leads to non-stereospecific allylic hydroxylation at C–7.

Radical–Anion Coupling Through Reagent Design: Hydroxylation of Aryl Halides [PDF]

open access: yes, 2021
The design and development of an oxime-based hydroxylation reagent, which can chemoselectively convert aryl halides (X = F, Cl, Br, I) into phenols under operationally simple, transition-metal-free conditions is described.

The microbiological hydroxylation of some steroids with a cortical side chain by Cephalosporium aphidicola

open access: yes, 1998
Hydroxylation of pregna-4-en-3-ones at C-11? by the fungus Cephalosporium aphidicola is shown to be affected by the nature of the pregnane side chain whilst hydroxylation at C-6? is unaffected.

Specificity Determinants of CYP1B1 Estradiol Hydroxylation [PDF]

open access: yes, 2013
Cytochrome P450 (P450)-catalyzed oxidation of the aromatic ring of estradiol can result in 2- or 4-hydroxylation. Which of these products is formed is biologically important, as the 4-hydroxylated metabolite is carcinogenic, whereas the 2-hydrox-ylated ...

Peroxide-Mediated Oxygenation of Organic Compounds by Fungal Peroxygenases

open access: yesAntioxidants, 2022
Unspecific peroxygenases (UPOs), whose sequences can be found in the genomes of thousands of filamentous fungi, many yeasts and certain fungus-like protists, are fascinating biocatalysts that transfer peroxide-borne oxygen (from H2O2 or R-OOH) with high ...

Efficient regio- and stereoselective access to novel fluorinated β-aminocyclohexanecarboxylates

open access: yesBeilstein Journal of Organic Chemistry, 2013
A regio- and stereoselective method has been developed for the synthesis of novel fluorinated 2-aminocyclohexanecarboxylic acid derivatives with the fluorine attached to position 4 of the ring.

Inhibition of CpLIP2 Lipase Hydrolytic Activity by Four Flavonols (Galangin, Kaempferol, Quercetin, Myricetin) Compared to Orlistat and Their Binding Mechanisms Studied by Quenching of Fluorescence

open access: yesMolecules, 2019
The inhibition of recombinant CpLIP2 lipase/acyltransferase from Candida parapsiolosis was considered a key model for novel antifungal drug discovery and a potential therapeutic target for candidiasis. Lipases have identified recently as potent virulence
