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.

Bioactivity Comments
The in vitro antibacterial activity of HSGN-218, against clinically relevant Clostridioides difficile strains (MIC in the range of 0.007-0.07 μM), is more potent than vancomycin [1]. HSGN-218 has been shown to have activity against other Gram-positive bacteria including vancomycin-resistant strains of Enterococcus faecium and Enterococcus faecalis [1] and methicillin-resistant Staphylococcus aureus (MRSA) [2].
The compound has a favourable safety profile, with 100% viability of Caco-2 cells at 64 μg/ml (>9000x of MIC) and is predicted to be restricted to the gut by virtue of its permeability properties [1].
