Description | PG 97-269 also called Acetyl-(D-Phe2,Lys15,Arg16,Leu27)-VIP (1-7)-GRF (8-27), is a selective high affinity VPAC1 receptor antagonist with negligible affinity for the PACAP type I receptor. The Ki values were 15 +/- 5 nM for the rat and 2 +/- 1 nM for the human VPAC1 receptors. PG 97-269 may be useful for the evaluation of the physiological role of VIP in rat and human tissues. |
