LUF7602   

GtoPdb Ligand ID: 10351

Synonyms: compound 17b [PMID: 30869893] | LUF-7602
Compound class: Synthetic organic
Comment: LUF7602 is a covalent (i.e. irreversible) antagonist of the adenosine A3 receptor [1]. The fluorosulfonyl warhead binds to amino acid residue Y265 of the receptor. LUF7602 does not bind to a mutant human A3R in which the tyrosine 265 residue is replaced by phenylalanine (Y265F), confirming this residue as the anchor site for the covalent interaction.
