A standalone enzyme, derived from the reductase domain of a polyketide synthase‐nonribosomal peptide synthetase hybrid enzyme, is identified as a pyrroline carboxylate reductase. This enzyme is involved in the biosynthesis of 3‐methylproline, an amino acid building block of a unique tricyclic pyrrolizidinone structure of a fungal metabolite ...

Removal of benzotriazoles from domestic wastewater using Pleurotus ostreatus fungal pellets
Removal of benzotriazoles from domestic wastewater using a fungal pellet reactor with Pleurotus ostreatus. The system effectively removed CBTR (70%), while BTR (19%), 5‐TTR (17%), and OH‐BTH (16%) showed moderate removal. Abstract Benzotriazoles are a group of persistent and mobile substances commonly found in aquatic environments due to inefficient ...

The nitrite anion: the key intermediate in alkyl nitrates degradative mechanism. [PDF]
Alkyl nitrates, _in vivo_, are metabolized to yield nitric oxide, and thiol groups are considered necessary cofactors. This statement is based on studies that underline how these species potentiate hemodynamic responsiveness to nitrates in patients with ...

Antiprotozoal Activity of Highly Substituted Pyrazole and Pyrimidine Derivatives
Based on previously identified antimalarial agents, a series of highly substituted pyrazole and pyrimidines derivatives has been synthesized and tested for antiplasmodial and antileishmanial activity. Selected derivatives show promising antiplasmodial effect with a predicted favorable pharmacokinetic profile.

Several derivatives incorporating five‐membered aromatic rings are described in this review as bile acid receptor modulators, particularly targeting the farnesoid X receptor and the G protein‐coupled bile acid receptor 1. This review provides a comprehensive analysis of patents and literature that is useful to support researchers in the design of new ...

A simple and rapid method to measure cholesterol binding to P450s and other proteins
Cholesterol plays an important role in cellular function and membrane compartmentalization and is involved in the interaction with more than a dozen of different proteins. Using three cholesterol-metabolizing cytochrome P450s (P450s 7A1, 46A1, and 11A1),
