A semi-quantitative translational pharmacology analysis to understand the relationship between in vitro ENT1 inhibition and the clinical incidence of dyspnoea and bronchospasm
ENT1 inhibition causes bronchospasm and severe dyspnoea in respiratory patients. Neutral or basic compounds with clogP > 5 have increased promiscuity to bind ENT1. ENT1 should be assessed within safety strategies for respiratory research programs. Quantitative translation enables informed risk-assessment of off-target ENT1 activity.
