Transcranial Magnetic Stimulation as a Translational Biomarker in Early‐Phase Anti‐Seizure Medication Development: A Randomized, Double‐Blind, Placebo‐Controlled Study in Generalized Epilepsy

open access: yesClinical Pharmacology &Therapeutics, Volume 120, Issue 3, Page 673-683, September 2026.
One‐third of epilepsy patients remain treatment‐resistant, underscoring the need for novel anti‐seizure medications (ASMs) and reliable biomarkers of central target engagement. Cortical hyperexcitability is a hallmark of epilepsy, making excitability a valuable pharmacodynamic biomarker for early‐phase drug development supporting go/no‐go decision ...

Systematic prioritization of candidate genes in camptothecin biosynthesis using multi‐omics and deep learning

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT

Effects of the HDAC6/8 Inhibitor MC1568, Alone and in Combination With Fluconazole, in Non‐Albicans Candida Species Infections

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
This study explores new antifungal strategies to combat non‐albicans Candida species. We tested clinically approved HDAC inhibitors—Vorinostat, Romidepsin, Tucidinostat—and the HDAC6/8‐selective MC1568, alone and with Fluconazole. The Fluconazole/MC1568 combination significantly enhanced antifungal activity and reduced biofilm formation.

The JAK1/2 Inhibitor Baricitinib Ameliorates Neuroinflammation and Symptoms in an Animal Model of Essential Tremor

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
In a harmaline‐induced essential tremor mouse model, baricitinib attenuated tremor severity and affective‐like abnormalities, suppressed cerebellar TNF‐α, IL‐6, NF‐κB, and Lingo‐1 expression, and showed supportive Purkinje‐cell morphological preservation.

Registered Clinical Trials of Ayahuasca and DMT: A Scoping Review

open access: yesClinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 94-108, July 2026.
Interest in ayahuasca and its main component, N,N‐Dimethyltryptamine (DMT), has currently moved from historical and experimental use into modern clinical development. Yet, current evidence is fragmented, and systematic mapping of trial methods and design choices remains limited.
