CTAP TFA
Based on 2 publication(s) in Google Scholar
CTAP TFA is a potent, highly selective, and BBB penetrant μ opioid receptor antagonist, with an IC50 of 3.5 nM. CTAP TFA displays over 1200-fold selectivity over δ opioid (IC50=4500 nM) and somatostatin receptors. CTAP TFA can be used for the study of L-DOPA-induced dyskinesia (LID) and opiate overdose or addiction.

CTAP TFA (10 mg/kg; IP, single) has no effect on L-DOPA-induced limb, axial, orolingual, or locomotor abnormal involuntary movements[1].
CTAP TFA is stable in the blood and serum of rats (T1/2 > 500 min), showing that the structure of this peptide offers enzymatic resistance[2].
CTAP TFA is extensively protein-bound to albumin in the perfusion medium (68.2%) and to proteins in rat serum (84.2%)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
