Kisspeptin 234 is a kisspeptin receptor antagonist, with the ability to antagonize kisspeptin-10-induced activation of gpr-54. Kisspeptin binds to its cognate receptor (i.e. gpr-54) on neurons that produce gonadotropin-releasing hormone (GnRH), and stimulates their activity, which in turn sends an obligatory signal for GnRH secretion, thereby gating down-stream events supporting reproduction. The development of kisspeptin receptor antagonists may provide a valuable tool for exploring the physiological and pathophysiological roles of kisspeptin in the regulation of reproduction, and could serve as a potential therapeutic agent for treating hormone-dependent disorders of reproduction, such as precocious puberty, endometriosis, as well as metastatic prostate cancer.

Cell lines
GnRH neurons
Reaction Conditions
100 pM ~ 10 μM kisspeptin 234
Applications
Kisspeptin 234 substantially inhibited kisspeptin-10 stimulation of inositol phosphate, with an IC50 value of 7 nM. At the doses of 1, 10 and 100 nM, kisspeptin 234 significantly reduced kisspeptin-10-induced GnRH neuron firing activity.
Animal models
Pubertal female rhesus monkeys
Dosage form
10 nM
Infusion of 10 nM kisspeptin 234 over 30 min through a microdialysis probe located in the stalk-median eminence region
Kisspeptin 234 was shown to reduce pulsatile GnRH secretion in female pubertal monkeys, which supports a key role of kisspeptin in puberty onset.
