Triptorelin, a decapeptide (pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH2), is a gonadotropin-releasing hormone agonist (GnRH agonist) used as the acetate or pamoate salts. By causing constant stimulation of the pituitary, it decreases pituitary secretion of gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Like other GnRH agonists, triptorelin may be used in the treatment of hormone-responsive cancers such as prostate cancer or breast cancer, precocious puberty, estrogen-dependent conditions (such as endometriosis or uterinefibroids), and in assisted reproduction. It is also used as therapy for gender identity disorder.
Nafarelin is a gonadotropin-releasing hormone agonist (GnRH agonist) which acts as an analog of GnRH. Nafarelin increases the release of FSH and LH by the anterior pituitary, which in turn leads to an increase of estrogen progesterone. When administered, Nafarelin has the purpose of causing increase estrogen that will negatively feed back upon hypothalamus to decrease GnRH ( negative feedback loop ) Through negative feedback, Nafarelin causes a decrease in pituitary secretion of gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Nafarelin may be used in the treatment of estrogen-dependent conditions (such as endometriosis or uterinefibroids), to treat central precocious puberty, and to control ovarian stimulation in IVF. It is normally delivered via a nasal spray. Nafarelin acetate is marketed by Searle (now part of Pfizer) under the brand name Synarel.
Leuprolide (1-3) is a manufactured version of a hormone used to treat prostate cancer, breast cancer, endometriosis, uterinefibroids, and early puberty.
C16 globotriaosylceramide is an endogenous sphingolipid found in mammalian cell membranes that is synthesized from C16 lactosylceramide . C16 globotriaosylceramide acts as a receptor for Shiga toxin in B cell-derived Raji cells and THP-1 monocytes. It accumulates in endothelial cells, pericytes, vascular smooth muscle cells, renal epithelial cells, dorsal ganglia neuronal cells, and myocardial cells in patients with Fabry disease. C16 globotriaosylceramide is also upregulated in plasma of patients with ovarian carcinoma compared to those with benign ovarian tumors or uterinefibroids.
