Description

General description

An internal standard for DHEAS, a metabolite of dehydroepiandrosterone (DHEA). DHEAS levels are measured by LC-MS/MS for determination of excess adrenal activity as observed in adrenal cancer, certain forms of congenital adrenal hyperplasia (CAH), and polycystic ovary syndrome.

Application

• Silk Fibroin Formed Bioadhesive Ophthalmic Gel for Dry Eye Syndrome Treatment: This research utilizes Cyclosporin A′s anti-inflammatory capabilities to formulate a novel ophthalmic gel aimed at treating Dry Eye Syndrome. By integrating Cyclosporin A into a silk fibroin-based gel, the study showcases a new bioadhesive delivery system that optimizes the drug′s ocular bioavailability and prolongs its therapeutic effects, highlighting the versatility of Cyclosporin A in pharmaceutical formulations (Hao T et al., 2024).
