Biological Activity

[Description]:

Threonyl-seryl-lysine, a bovine pineal antireproductive tripeptide, has antigonadotropic activity. Threonyl-seryl-lysine binds to luteinizing hormone-releasing hormone (LHRH) at a site comprised of LHRH 2-5[1][3].

[In Vivo]

Threonyl-seryl-lysine (175 ng, i.p.) reduces the 5-day compensatory ovarian hypertrophy in unilaterally ovariectomized (UO) mice[1]. Threonyl-seryl-lysine (1 or 5 μg, i.p.) delays vaginal opening time in female Charles River CD rats[2]. Threonyl-seryl-lysine (1 and 10 μg, s.c., for 15 days) increases the weight of ovaries and of adrenals in mice[4]. Animal Model: Unilaterally ovariectomized (UO) mice Dosage: 175 ng Administration: Intraperitoneal injection (i.p.) Result: Reduced serum follicle stimulating hormone (FSH) in UO mice.
