Leuprorelin (Leuprolide) EP Impurity F

Fertirelin Acetate

Fertirelin acetate is a potent LHRH agonist. After a transient increase, continuous administration results in downregulation of LH and FSH levels followed by a suppression of ovarian and testicular steroid biosynthesis.

Thymopentin Acetate

Thymopentin, also known as TP-5, is a synthetic derivative of thymopoietin, a thymic hormone, and has immunoregulatory properties. Thymopentin interacts with T cells, reduces endocrine and behavioral responses to experimental stress. It is also found to increase the number of cells undergoing apoptosis in irradiated cells and selectively bind to apoptotic cells.

GLP-1 (7-37) Acetate

Glucagon-like peptide-1 (GLP-1) is an incretin derived from the transcription product of the proglucagon gene. The major source of GLP-1 in the body is the intestinal L cell that secretes GLP-2 as a gut hormone.

Alarelin acetate

Alarelin acetate is a synthetic LH-RH agonist, and stimulates the release of FSH and LH from the pituitary gland. It is known for its induction of ovulation and used to treat endmometriosis.

Thymosin β4 Acetate

Thymosin β4 is a 43 amino acid peptide which is regarded as the main intracellular G-actin sequestering peptide. Extracellular thymosin β4 may contribute to physiological processes such as angiogenesis, wound healing and regulation of inflammation.

Teduglutide

Teduglutide is a polypeptide consisting of 33 amino acids. It is glucagon-like peptide-2 (GLP-2) analogue that is used for the treatment of short bowel syndrome.

Teriparatide Acetate

Teriparatide(recombinant human parathyroid hormone) /PTH (1-34) (human) corresponds to the N-terminal part of human parathyroid hormone, a peptide consisting of 84 amino acids.

Somatostatin

Somatostatin is a tetradecapeptide which can suppress the growth hormone (GH) secretion and control the pituitary hormone secretion in human CNS.

Carbetocin

Carbetocin is a long-acting synthetic agonist analogue of human oxytocin, with antihemorrhagic and uterotonic activities. Upon administration, carbetocin targets, binds to and activates peripheral oxytocin receptors that are present on the smooth musculature of the uterus. This causes uterus contractions and prevents excessive bleeding after childbirth, particularly following Cesarean section, and may be used to decrease blood loss during hysteroscopic myomectomy.

Atosiban

Atosiban is a nonapeptide, desamino-oxytocin analogue, and a competitive vasopressin/oxytocin receptor antagonist (VOTra). Atosiban is indicated to delay imminent pre-term birth in pregnant adult women. Atosiban is useful in improving the pregnancy outcome of in vitro fertilization-embryo transfer (IVF-ET) in patients with repeated implantation failure (RIF). The pregnancy rate improved from zero to 43.7%.
