GtoPdb Ligand ID: 9552

Compound class: Synthetic organic
Comment: Nitrosoprodenafil is a novel nitrosated analogue of the PDE5 inhibitor sildenafil, that acts as a prodrug releasing aildenafil (methisosildenafil; PubChem CID 16721107) and NO [1]. NO-induced effects on vasodilation are synergistic with inhibition of PDE5 action. This type of compound has been avoided by conventional pharmaceutical companies because of the serious risk of causing a life-threatening drop in blood pressure, and because of the hepatotoxicity of nitrosamines.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.
