compound 5a [PMID: 27536893]   Click here for help

GtoPdb Ligand ID: 9300

Compound class: Synthetic organic
Comment: Compound 5a causes microtubule fragmentation via modulation of the hydrolase activity of katanin [1]. The precise binding site has not been determined, but could reside within catalytic site of KATNA1 (p60 subunit) due to the purine scaffold of 5a. A docking model suggests that 5a may bind in a position which stabilizes the p60 structure and enhances the microtubule severing activity of katanin.
Katanin-modulating compounds could provide an alternative to vinca alkaloid and taxane microtubule targeting agents (MTAs), which suffer from issues of drug-induced resistance developing in clinical use.

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.
