ITURELIX, a decapeptide, is a gonadotropin-releasing hormone antagonist.

Prazarelix is gonadorelin (GnRH) antagonist. It is primarily used in assisted reproduction to control ovulation. The drug works by blocking the action of GnRH upon the pituitary, thus rapidly suppressing the production and action of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Ozarelix is a luteinizing hormone-releasing hormone (LHRH) antagonist. It is known that LHRH antagonist exerts rapid inhibition of luteinizing hormone and follicle stimulating hormone with an accompanying rapid decrease in sex hormones. Thus this inhibitor can be effective in a variety of hormonally dependent disease including prostate cancer, benign prostatic hyperplasia (BPH), and endometriosis. Ozarelix was developed for the treatment of all these diseases including Alzheimer's disease. However, in January 2010 Spectrum Pharmaceuticals announced that it was discontinuing development of ozarelix in BPH. Because the low-dose intermittent therapy was disappointing in the treatment of lower urinary tract symptoms in men with BPH. The development of the drug for Alzheimer's disease was also discontinued. Ozarelix completed phase II trials for the treatment of prostate cancer and is in preclinical trials for the treatment of endometriosis and ovarian cancer.

GO-203-2c is a cell-penetrating peptide that binds to MUC1, a protein that causes cancer (oncoprotein). MUC1 is over-expressed in many human cancers, such breast, prostate, lung, colon, pancreas, and ovary cancer, and has been associated with poor prognosis. GO-203-2c blocks homodimerization of the MUC1-C subunit required for nuclear translocation and downstream signaling. This binding eventually leads to cell death (in laboratory setting). Since MUC1 is over-expressed in many cancers, the potential of GO-203-2c in treatment of cancers is being investigated. A phase I clinical trial has been completed in which GO-203-2c was shown to be safe and demonstrating both anti-leukemia and immunomodulatory effects. A phase II study is investigating its potential in the treatment of Acute Myeloid Leukemia.

alpha-MELANOTROPIN (also known as an alpha-melanocyte-stimulating hormone or alpha MSH) is an endogenous melanocortin 1-receptor agonist, which exclusively expressed in cells of the melanocytic lineage. alpha-MELANOTROPIN possesses anti-inflammatory properties and antagonizes proinflammatory mediators, including TNF-alpha, IL-6 and NO, and induces anti-inflammatory cytokine IL-10. alpha-MELANOTROPIN was studied in phase I clinical trial in patients with acute renal failure. In addition, this compound was assigned of orphan designation for the treatment of chronic beryllium disease.
