GR 64349
Based on 1 Customer Validation
GR 64349 is a selective neurokinin 2 (NK2) receptor agonist. GR 64349 selectively activates the NK-2 receptor subtype. GR 64349 activates tonic and rhythmic bladder contractions of the micturition reflex. GR 64349 acetate does not inhibit rhythmic bladder contraction activation induced by normal saline. GR 64349 induces inward currents.

NK2R |
GR 64349 contracts isolated rat bladder tissues in vitro, with potency comparable to that of the selective NK-1 agonist GR 73632 (HY-P1192)[1].
GR 64349 (300-500 nM) generates inward currents in some neurons[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
GR 64349 (intracerebroventricular injection) does not modulate centrally mediated rhythmic bladder contractions in urethane-anesthetized rats[1].

Animal Model:Wistar-Morini (male, 300-350 g, urethane-anesthetized, urinary bladder cannulated and filled to 0.25 mL saline)[1]
-
Dosage:0.1 nmoles/kg; 1 nmoles/kg; 10 nmoles/kg
-
Administration:i.a.
-
Result:Induced a dose-related increase in intravesical pressure (tonic contraction, TC) and activation of rhythmic bladder contractions (RBC).
Reached maximal TC amplitude of 37 mmHg (n=6-7).
Achieved ED50 of 0.61 nmoles/kg i.a. for TC (95% confidence limits: 0.36-1.03).
Achieved ED50 of 0.43 nmoles/kg i.a. for RBC (95% confidence limits: 0.15-1.26).
Observed RBC in 4-6 out of 6 preparations at 1 nmoles/kg i.a.
Left TC largely unaffected after topical TTX pretreatment, which abolished RBC.
Showed maximal TC amplitudes of 28 mmHg (without antagonist) and 26 mmHg (with GR 82334 pretreatment, n=5), with GR 82334 not inhibiting GR 64349-induced TC.
