An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no
