Associations of MTNR1A with chemical compounds

  • Dissociation constants for competition of 11 partial agonists and antagonist for 2-[125I]-iodomelatonin binding were between 15.5 (luzindole, pKi: 7.7) to 362 (4-phenyl-2-chloroacetamidotetraline, pKi: 9.1) fold higher for the Mel1b than for the Mel1a melatonin receptor [10].
