Cetrorelix diacetate (SB-075 diacetate) is a potent gonadotropin-releasing hormone (GnRH) receptor antagonist with an IC50 of 1.21 nM.

Kisspeptin-54(human) (Metastin(human)) is an endogenous ligand for kisspeptin receptor (KISS1, GPR54). Kisspeptin-54(human) binds to rat and human GPR54 receptors with Ki values of 1.81 nM and 1.45 nM, respectively. Kisspeptin-54(human) hinders tumor metastasis and stimulates gonadotropin secretion.

Kisspeptin-54(human) TFA (Metastin(human) TFA) is an endogenous ligand for kisspeptin receptor (KISS1, GPR54). Kisspeptin-54(human) TFA binds to rat and human GPR54 receptors with Ki values of 1.81 nM and 1.45 nM, respectively. Kisspeptin-54(human) TFA hinders tumor metastasis and stimulates gonadotropin secretion.

Lecirelin is a synthetic GnRH (gonadotropin releasing hormone) analogue which shows a great efficacy in the treatment of bovine ovarian follicular cysts.
