2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

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.

Summary of Clinical Use Click here for help
Guaifenesin is an expectorant used to reduce chest congestion caused by the common cold, infections, or allergies. This drug is available with or without prescription in the US. Guaifenesin is often sold in fixed-mixture formulations containing codeine (antitussive) and pseudoephedrine( decongestant) to treat painful and persistent coughs with mucus buildup and nasal congestion.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Guaifenesin works by thinning and loosening mucus in the airways, clearing congestion, and making breathing easier, although the precise mechanistic target of drug action is unknown.
