Biochem/physiol Actions
Ser-Tyr-His(Bz)-Leu-Arg-Pro-NHEt ([D-His(Bzl)6]-LH-RH Fragment 4-9) is a peptide from GnRH (gonadotropin-releasing hormone) agonist, histerelin. GnRH (Glp-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2), which is also referred as LHRH (luteinizing hormone-releasing hormone) or gonadorelin, is crucial for mammalian reproduction and is released from hypothalamic neurons. It is responsible for the secretion of gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), from the pituitary glands. Mutations in GnRH are associated with normosmic congenital hypogonadotropic hypogonadism. Histerelin is used for the treatment of central precocious puberty in children.

Drug-target residence time is an important, yet often overlooked, parameter in drug discovery. Multiple studies have proposed an increased residence time to be beneficial for improved drug efficacy and/or longer duration of action. Currently, there are many drugs on the

Normosmic congenital hypogonadotropic hypogonadism (nCHH) is a rare reproductive disease leading to lack of puberty and infertility. Loss-of-function mutations of GNRH1 gene are a very rare cause of autosomal recessive nCHH. R31C GNRH1 is the only missense mutation that affects

Characterization of the genetic defects causing gonadotropic deficiency has made a major contribution to elucidation of the fundamental role of Kisspeptins and Neurokinin B in puberty onset and reproduction. The absence of puberty may also reveal neurodevelopmental disorders caused by
