In Vitro The formation of LHRH 4-10, LHRH 7-10, and LHRH 6-10Co-incubation are inhibited by known enzyme inhibitors including Captopril (HY-B0368) (an ACE inhibitor), Thiorphan (HY-W013375) (an EP24.11 inhibitor), and Ethylenediaminetetraacetic acid (HY-Y0682) (an EP24.15 inhibitor)[3]. LH-RH (7-10) inhibits the binding of 125I-labeled GnRH to monoclonal antibody P81662 with an IC50 value of 1.7 nM[4].
In Vivo LH-RH (7-10) (i.v.) increases esterase activity in plasma kinin system in rats[1]. LH-RH (7-10) (ntracarotid infusion i.v.; single dose) stimulates a significant increase in plasma LH concentration in the jugular vein[2]. Animal Model: New Zealand White Rabbit[2] Dosage: 100, 500 and 2500 ng dissolved in 0-9% (w/v) NaCl solution and diluted Administration: Ntracarotid infusion; infused with a constant volume of 7-5 mL per 30 min Result: Caused LH release in the female rabbit during various reproductive conditions.
