uterine fibroids

Estradiol (E2) is a naturally occurring steroidal sex hormone that is essential for female fertility and maintenance of secondary sexual characteristics. Estradiol upregulates IL-6 expression through estrogen receptor beta (ERβ).

Linzagolix is a small-molecule, non-peptide, orally active gonadotropin-releasing hormone antagonist (GnRH antagonist) which is under development by Kissei Pharmaceutical and ObsEva for the treatment of uterine fibroids, endometriosis, and adenomyosis. As of December 2020, it is under review for approval for uterine fibroids, is in phase III clinical trials for endometriosis, and is in phase II clinical studies for adenomyosis.

Cancer-Targeting Compound 1 can be used in the study of hormone-related cancers, including the treatment or prevention of fibroids, uterine leiomyomas, polycystic ovarian syndrome, or hormone-dependent Cancer, among others.

Vilaprisan (BAY 1002670) is a novel orally available and selective progesterone receptor modulator (SPRM) with antiproliferative activity against uterine fibroids (UF) and can be used for the study of uterine fibroids.

Mifepristone (C-1073) is a progesterone-receptor (IC50=0.2 nM) and glucocorticoid-receptor antagonist (IC50=2.6 nM). Mifepristone is used to terminate pregnancy, treat uterine fibroids, and treat endometriosis.

Opigolix, a Gonadotropin-releasing hormone receptor antagonist, treats hormone-dependent conditions by inhibiting the actions of gonadotropin-releasing hormone (GnRH).

Linzagolix choline is an orally available non-peptide gonadotropin-releasing hormone (GnRH) antagonist. It can be used to study pain associated with uterine fibroids and endometriosis.

LY2066948 is a selective oral estrogen receptor modulator (SERM) with high affinity for estrogen receptors ERα and ERβ (Ki of 0.51 and 1.36 nM, respectively) and displays potent anti-estrogenic activity. It effectively blocks the increase in uterine weight induced by ethinylestradiol in immature rats. LY2066948 is utilized in the research of uterine fibroids and myomas.

Histrelin (Supprelin LA) acetate is a nonapeptide analog of gonadotropin-releasing hormone (GnRH) with added potency. It is considered a GnRH agonist. Histrelin is used in the treatment of hormone-sensitive cancers of the prostate in men and uterine fibroids in women.

Leuprolide (1-3) is a manufactured version of a hormone used to treat prostate cancer, breast cancer, endometriosis, uterine fibroids, 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 uterine fibroids.

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 uterine fibroids), 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.

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 uterine fibroids), and in assisted reproduction. It is also used as therapy for gender identity disorder.

BAY 1214784, a potent, selective, and orally active spiroindoline derivative compound, serves as an antagonist of the human gonadotropin-releasing hormone receptor (hGnRH-R). It notably reduces plasma luteinizing hormone levels by up to 49%, demonstrating low pharmacokinetic variability and good tolerability. This compound shows promise for research into uterine fibroids.
