Leveraging molecular dynamics simulations to study psychedelics and their receptors in future drug development.
Expert opinion on drug discovery May 1, 2026 Cong Zhang, Pu Jiang, Yibo Wang et al.
Psychedelics hold therapeutic promise for central nervous system disorders but are limited by hallucinogenic side effects. Molecular dynamics simulations provide atomic-level insights into receptor interactions, helping to overcome these challenges and guide the development of safer, more effective therapies. This perspective reviews how MD simulations reveal mechanisms such as biased signaling, receptor multimerization, and lipid modulation, and discusses their role in validating cryo-EM binding sites. Challenges in force fields, structural data, and system complexity must be addressed to advance rational drug design. MD simulations are transforming psychedelic drug discovery from serendipity to precision design, with the goal of a predictive 'digital pharmacology' platform.
