Flavone-C-glycosides from L. as possible inhibitors of phosphodiesterase-5 (PDE5): , molecular docking and molecular dynamics studies.

Phosphodiesterase-5 (PDE5) is a homodimeric enzyme that specifically targets cyclic guanosine monophosphate (cGMP), that mediates many downstream effects such as vasodilation, neurotransmission, and calcium homeostasis. Considering the functions of cGMP, inhibition of PDE5 has been established to have several therapeutic effects in disease conditions such as cancer, cardiovascular diseases and Alzheimer's disease. Consequently, many PDE5 inhibitors were developed but with severe adverse effects such as non-arteritic anterior ischemic optic neuropathy (NAION), priapism, etc.
