A New Vista of Opportunity in Diabetes Management: Natural Product‐Based β‐cell Preservation

Food Chemistry International, EarlyView.
Preserving functional β‐cells via natural products offers promising strategy for diabetes treatment. ABSTRACT A defining characteristic of diabetes is β‐cell failure, in which β‐cells cannot modulate insulin secretion to compensate for escalating insulin resistance, pushing forward disease development.

Benzylamines as highly potent inhibitors of the sterol biosynthesis pathway in Leishmania amazonensis leading to oxidative stress and ultrastructural alterations

Scientific Reports, 2022
Leishmaniasis is a neglected disease caused by protozoan parasites of the Leishmania genus. Benzylamines are a class of compounds selectively designed to inhibit the squalene synthase (SQS) that catalyzes the first committed reaction on the sterol ...

5-Fluorocytosine antagonizes the action of sterol biosynthesis inhibitors in Candida glabrata [PDF]

Journal of Antimicrobial Chemotherapy, 1999
The concentration-dependent antagonistic interaction between 5-fluorocytosine and a sterol biosynthesis inhibitor (SBI) was studied using intact cells and cell-free extracts of Candida glabrata. 5-Fluorocytosine promoted incorporation of radioactivity into 4-desmethylsterols (P < 0.01), and enhanced the relative and absolute increases of ergosterol (P <

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

Food Biomacromolecules, EarlyView.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

Structural complex of sterol 14α-demethylase (CYP51) with 14α-methylenecyclopropyl-Δ7-24, 25-dihydrolanosterol

Journal of Lipid Research, 2012
Sterol 14α-demethylase (CYP51) that catalyzes the removal of the 14α-methyl group from the sterol nucleus is an essential enzyme in sterol biosynthesis, a primary target for clinical and agricultural antifungal azoles and an emerging target for ...
