4-Me-PDTic HCl

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 555307

CAS#: 2209073-52-7 (HCl)

Description: 4-Me-PDTic is a potent and selective Kappa Opioid Receptor Antagonist. 4-Me-PDTic had a Ke = 0.37 nM in a [35S]GTPγS binding assay and was 645- and >8100-fold selective for the κ relative to the μ and δ opioid receptors, respectively. Calculated logBB and CNS (central nervous system) multiparameter optimization (MPO) and low molecular weight values all predict that 4-Me-PDTic will penetrate the brain and pharmacokinetic studies in rats shows that 4-Me-PDTic does indeed penetrate the brain.
