[Synonym ]:
(Leu31,Pro34)-Neuropeptide Y (human, rat)

Biological Activity

[Description]:

[Leu31,Pro34]-Neuropeptide Y(human,rat) is a specific neuropeptide Y Y1 receptor agonist. [Leu31,Pro34]-Neuropeptide Y(human,rat) slao inhibits Y4, Y5. [Leu31,Pro34]-Neuropeptide Y(human,rat) can increase blood pressure in anesthetized rats and increases food intake[1][2].

[In Vitro]

[Leu31,Pro34]-Neuropeptide Y(human,rat) has Ki values of 0.39 nM, 0.499 nM, 0.31 nM for Y1, Y4, Y5 in HEK cell lines. [Leu31,Pro34]-Neuropeptide Y(human,rat) has a Ki of >1000 for Y2 in HEK cell lines[2].

[In Vivo]

[Leu31,Pro34]-Neuropeptide Y(human,rat) (30 pmol; microinjected into paraventricular nucleus) increases food intake in the rats (350±400 g)[3].
