Kisspeptin-10
clinical trialsAlso known as: KP-10, Metastin fragment
Kisspeptin-10 (KP-10), a decapeptide fragment of the metastin/kisspeptin-1 protein, acts as a potent agonist at the KISS1 receptor (KISS1R, GPR54). Its primary mechanism involves direct activation of hypothalamic gonadotropin-releasing hormone (GnRH) neurons, thereby serving as an upstream regulator of the entire reproductive hormone axis. By stimulating pulsatile GnRH secretion, KP-10 indirectly promotes luteinizing hormone (LH) and follicle-stimulating hormone (FSH) release from the anterior pituitary, making it a critical modulator of puberty onset, fertility, and gonadal function. Key research findings from clinical trials demonstrate that exogenous KP-10 administration robustly elevates LH and, to a lesser extent, FSH levels in healthy adults, with effects dependent on dose and route of administration. Studies have shown its utility in diagnosing and treating hypothalamic amenorrhea, hypogonadotropic hypogonadism, and certain forms of infertility, as it can restore endogenous GnRH pulsatility. Additionally, KP-10 has been investigated for its role in metabolic regulation, with evidence linking kisspeptin signaling to energy balance and glucose homeostasis, though these applications remain exploratory. Clinically, KP-10 is being evaluated as a diagnostic tool for assessing hypothalamic-pituitary-gonadal axis integrity and as a therapeutic agent for conditions characterized by impaired GnRH secretion, such as functional hypothalamic amenorrhea. Its rapid onset and short half-life offer advantages over traditional gonadotropin therapies, though further trials are needed to establish optimal dosing, safety, and long-term efficacy.

C63H83N17O14Research & studies
Kp-10 ameliorated TNF-α-induced senescence in chondrocytes, reducing SA-β-gal staining and increasing telomerase activity.; Kp-10 modulated expression of hTERT and TERF2, and suppressed the p53/p21 pathway.; Kp-10 restored SIRT1 expression, which was downregulated by TNF-α.; Silencing SIRT1 abolished Kp-10's protective effects, indicating SIRT1 is essential for its anti-senescence action.
KP-10 levels were reduced in both cerebral aneurysm patients and mouse models.; KP-10 reduced cerebral aneurysm size in wild-type mice but not in Gpr54 knockout mice.; KP-10 inhibited Ang II-induced proliferation, tube formation, and VEGF-A expression in HBMVECs by reducing Egr-1.; The effects of KP-10 were dependent on Gpr54, as they were abolished in Gpr54 knockdown conditions.
A screening and confirmation procedure for kisspeptin-10 in urine was successfully validated using LC-MS.; Four metabolites (y9, y8, y7, y5) were identified from serum incubation and included in the full-scan screening.; A degradation product from tryptophan oxidation to kynurenine was observed, requiring further kinetic study.; A black-market vial showed no unexpected impurities but had more degradation than the reference standard.
Kp-10 binding to Gpr54 upregulates Dusp18, which dephosphorylates Src at Tyr 416.; Gpr54 recruits active Src and Dusp18 at its proline/arginine-rich C-terminal motif.; Kiss1, Gpr54, and Dusp18 knockout mice show osteoclast hyperactivation and bone loss.; Kp-10 treatment suppresses osteoclast activity and prevents bone loss in vivo.
