Elagolix (ABT-620) is an oral gonadotropin-releasing hormone antagonist being studied for the treatment of endometriosis and uterine fibroids. The U.S. Food and Drug Administration (FDA) approved AbbVie's elagolix under the brand name Orilissa as the first and only oral gonadotropin-releasing hormone (GnRH) antagonist specifically developed for women with moderate to severe endometriosis pain.

Nintedanib is a receptor tyrosine kinase inhibitor with potential antiangiogenic and antineoplastic activities. It is the only kinase inhibitor drug approved to treat idiopathic pulmonary fibrosis. that targets multiple receptor tyrosine kinases (RTKs) and non-receptor tyrosine kinases (nRTKs). Nintedanib inhibits the following RTKs: platelet-derived growth factor receptor (PDGFR) α and β, fibroblast growth factor receptor (FGFR) 1-3, vascular endothelial growth factor receptor (VEGFR) 1-3, and Fms-like tyrosine kinase-3 (FLT3). Among them, FGFR, PDGFR, and VEGFR have been implicated in IPF pathogenesis. Nintedanib binds competitively to the adenosine triphosphate (ATP) binding pocket of these receptors and blocks the intracellular signaling which is crucial for the proliferation, migration, and transformation of fibroblasts representing essential mechanisms of the IPF pathology.

Dehydroepiandrosterone (INTRAROSA™, prasterone) is a major C19 steroid produced from cholesterol by the adrenal cortex. It is also produced in small quantities in the testis and the ovary. Dehydroepiandrosterone (INTRAROSA, prasterone) is structurally similar to, and is a precursor of, androstenedione, testosterone, estradiol, estrone and estrogen. It indicated for the treatment of moderate to severe dyspareunia, a symptom of vulvar and vaginal atrophy, due to menopause. The mechanism of action of dehydroepiandrosterone (INTRAROSA, prasterone) in postmenopausal women with vulvar and vaginal atrophy is not fully established.

Desvenlafaxine is a dual serotonin and norepinephrine reuptake inhibitor in vitro and in vivo that demonstrates good brain-to-plasma ratios. Desvenlafaxine has demonstrated antidepressant effects in preclinical studies. Pfizer is developing an oral, extended-release formulation of desvenlafaxine for the treatment of major depressive disorder. Desvenlafaxine has been registered and is available on the market for the treatment of major depressive disorder in adults.

Sitagliptin (MK-0431), chemically (2R)-4-Oxo-4-[3- (trifluoromethyl)-5,6-dihydro[1,2,4]triazolo[4,3-a]pyrazin- 7(8H)-yl]-1-(2,4,5-trifl uorophenyl)butan-2-amine has a very high selectivity towards DPP-4, with an IC(50) of 18 nM. There is no affinity towards other DDP enzymes (DPP- 8 and DPP-9). It has been approved for the treatment of type 2 diabetes in the USA and Europe and is registered by the name Januvia (Merck Pharmaceuticals, Whitehouse Station, NJ, USA). In healthy volunteers and in patients with type 2 diabetes of different ethnic background, the tolerability of different doses given once or twice daily is good. The drug works to competitively inhibit a protein/enzyme, dipeptidyl peptidase 4 (DPP-4), that results in an increased amount of active incretins (GLP-1 and GIP), reduced amount of release of glucagon (diminishes its release) and increased release of insulin. Sitagliptin is an incretin enhancer and the first marketed medication belonging to the gliptin class. In fact, no published literature exists regarding incidence or severity of hypoglycemia when sitagliptin is used off-label in combined with insulin therapy. However, is recommended to use methods to avoid hypoglycemia when using this off-label combination. Approximately 79% of sitagliptin is excreted unchanged in the urine with metabolism being a minor pathway of elimination. Elimination of sitagliptin occurs primarily via renal excretion and involves active tubular secretion. Sitagliptin is a substrate for human organic anion transporter-3 (hOAT-3), which may be involved in the renal elimination of sitagliptin

Dasatinib [BMS 354825] is an orally active, small molecule, dual inhibitor of both SRC and ABL kinases that is under development with Bristol-Myers Squibb for the treatment of patients with chronic myelogenous leukaemia (CML) and imatinib-acquired resistance/intolerance. It’s used for the treatment of adults with chronic, accelerated, or myeloid or lymphoid blast phase chronic myeloid leukemia with resistance or intolerance to prior therapy. Also indicated for the treatment of adults with Philadelphia chromosome-positive acute lymphoblastic leukemia with resistance or intolerance to prior therapy. While imatinib remains a frontline therapy for CML, patients with advanced disease frequently develop resistance to imatinib therapy through multiple mechanisms. Dasatinib is also undergoing preclinical evaluation for its potential as a therapy against multiple myeloma. Bristol-Myers Squibb has a composition-of-matter patent covering this research approach that will expire in 2020. Dasatinib, at nanomolar concentrations, inhibits the following kinases: BCR-ABL, SRC family (SRC, LCK, YES, FYN), c-KIT, EPHA2, and PDGFRβ. Based on modeling studies, dasatinib is predicted to bind to multiple conformations of the ABL kinase.

Darunavir (trade name Prezista) is an orally active bis-furan-sulfonamide inhibitor of human immunodeficiency virus (HIV-1) protease. Darunavir was developed by Tibotec Pharmaceuticals (now Janssen R&D Ireland). Darunavir is indicated for the treatment of HIV-1 infection in adult and pediatric patients 3 years of age and older. The drug is co-administered with low-dose ritonavir and other anti-HIV agents. It is the only antiretroviral that has been registered at two different doses, 800/100 mg once-daily or 600/100 mg twice-daily, allowing its administration throughout the entire course of HIV disease, from naive subjects without any HIV-1 resistance to heavily treatment-experienced subjects with widespread triple-class family resistance.

Ibandronic acid (INN) or ibandronate sodium (USAN) is a potent bisphosphonate drug developed by Hoffman La Roche and used in the prevention and treatment of osteoporosis and metastasis-associated skeletal fractures in people with cancer. Ibandronate is indicated for the treatment and prevention of osteoporosis in post-menopausal women. In May 2003, the U.S. Food and Drug Administration (FDA) approved Ibandronate as a daily treatment for post-menopausal osteoporosis. The basis for this approval was a three-year, randomized, double-blind, placebo-controlled trial women with post-menopausal osteoporosis. Every participant also received daily oral doses of calcium and 400IUs [international units] of vitamin D. At the study's conclusion, both doses significantly reduced the occurrence risk of new vertebral fractures by 50–52 percent when compared to the effects of the placebo drug. Ibandronate is efficacious for the prevention of metastasis-related bone fractures in multiple myeloma, breast cancer, and certain other cancers. In 2008, the U.S Food and Drug Administration (FDA) issued a communication warning of the possibility of severe and sometimes incapacitating bone, joint and/or muscle pain.[4] A study conducted by the American Society of Bone and Mineral Research concluded that long-term use of bisphosphonates, including Boniva, may increase the risk of a rare but serious fracture of the femur. Ibandronic acid is marketed under the trade names Boniva in the USA, Bondronat in Europe, Bonviva in Asia, Ibandrix in Ecuador and Bondrova in Bangladesh.

Tizoxanide, the primary active metabolite of the FDA approved drug nitazoxanide, an anti-infective that has been approved for the treatment of diarrhea caused by Giardia lamblia. Tizoxanide, an active metabolite of nitazoxanide in humans, is also an antiparasitic drug of the thiazolide class. It has broad-spectrum antiparasitic and broad-spectrum antiviral properties. Besides, it has being found that Tizoxanide exhibits appreciable antagonist activity for both mGluR1 and mGluR5 (IC50 = 1.8 uM and 1.2 uM, respectively).

(R)-9-(2-Phosphonylmethoxypropyl)adenine (PMPA known as tenofovir) is an antiviral drug. Diphosphate of PMPA acts as a selective inhibitor of the HIV-1 reverse transcriptase. Tenofovir disoproxil was approved for clinical use for the treatment of HIV infection (AIDS) and chronic HBV infection.
