SULFUR HEXAFLUORIDE is a component of LUMASON® (sulfur hexafluoride lipid-type A microspheres). It is an ultrasound contrast agent indicated for use in the heart echocardiography and in ultrasonography of the liver and the urinary tract. The sulfur hexafluoride lipid microspheres are composed of SF6 gas in the core surrounded by an outer shell monolayer of phospholipids with palmitic acid as a stabilizer.

Tasimelteon, developed by Vanda Pharmaceuticals Inc under license from Bristol-Myers Squibb Co, is a melatonin receptor agonist. Tasimelteon differs structurally from melatonin and drugs with known melatonin agonist activity, in particular by its distinct aromatic group and linker. Tasimelteon bears also no structural relationship to any other approved active substance. Tasimelteon is presumably acts through activation of MT1 and MT2 G-protein coupled receptors, which are involved primarily in inhibition of neuronal firing and phase shift of circadian rhythms. Tasimelteon is approved for the treatment of Non24-Hour Sleep-Wake Disorder.

Apremilast (brand name Otezla) selective inhibitor of phosphodiesterase 4 is used for the treatment of patients with moderate to severe plaque psoriasis. OTEZLA is the first and only PDE4 inhibitor approved for the treatment of plaque psoriasis, a chronic inflammatory disease of the skin resulting from an uncontrolled immune response. Apremilast also inhibits spontaneous production of TNF-alpha from human rheumatoid synovial cells. It has anti-inflammatory activity. By inhibiting PDE-4, apremilast increases intracellular levels of cAMP and thereby inhibits the production of multiple proinflammatory mediators including PDE-4, TNF-alpha, interleukin-2 (IL-2), interferon-gamma, leukotrienes, and nitric oxide synthase.

Olaparib is an oral inhibitor of poly (ADP-ribose) polymerase enzymes, including PARP1, PARP2, and PARP3 which are involved in normal cellular homeostasis, such as DNA transcription, cell cycle regulation, and DNA repair. Olaparib has shown activity in ovarian and breast tumors with known BRCA mutations and was the first FDA approved drug in this class. Lynparza (olaparib) is indicated for treatment of gBRCA-mutated advanced ovarian cancer. Its use together with other chemotherapy medicines can lead to increased effects on the blood resulting in reduction in the numbers of white blood cells and platelets, and anaemia.

Belinostat is a hydroxamate-type histone deacetylase inhibitor indicated for the treatment of relapsed or refractory peripheal T-cell lymphoma. The compound received orphan drug designation for the treatment of malignant thymomas. Acting on a histone deacetylase Belinostat causes the accumulation of acetylated histones and other proteins, inducing cell cycle arrest and/or apoptosis of some transformed cells. Belinostat targets HDAC enzymes, thereby inhibiting tumor cell proliferation, inducing apoptosis, promoting cellular differentiation, and inhibiting angiogenesis. This agent may sensitize drug-resistant tumor cells to other antineoplastic agents, possibly through a mechanism involving the down-regulation of thymidylate synthase. PXD101 has been shown in preclinical studies to have the potential to treat a wide range of solid and hematologic malignancies either as a monotherapy or in combination with other active agents, and both an oral and intravenous formulation of the drug are being evaluated in clinical trials.

Alogliptin (trade name Nesina in the US and Vipidia in Europe) is an orally administered anti-diabetic drug in the DPP-4 inhibitor class, discovered by Takeda Pharmaceutical Company's wholly owned subsidiary, Takeda San Diego, Inc. (former Syrrx) which was acquired by Takeda in 2005. Alogliptin does not decrease the risk of heart attack and stroke. Like other members of the gliptin class, it causes little or no weight gain, exhibits relatively little risk of causing hypoglycemia, and exhibits relatively modest glucose-lowering activity. Alogliptin and other gliptins are commonly used in combination with metformin in patients whose diabetes cannot adequately be controlled with metformin alone.

Macitentan is an orally active, dual endothelin receptor antagonist with tissue targeting properties. Macitentan inhibits both ETA and ETB receptors and prevents them from binding to ET-1. Macitentan displays high affinity and sustained occupancy of the ET receptors in human pulmonary arterial smooth muscle cells. One of the metabolites of macitentan is also pharmacologically active at the ET receptors and is estimated to be about 20% as potent as the parent drug in vitro. Macitentan is approved in the EU (as monotherapy or combination therapy) for the long-term treatment of pulmonary arterial hypertension (PAH) in adults of WHO functional class II or III, and in the USA for the treatment of PAH (WHO group I) to delay disease progression and reduce hospitalization for PAH.

Vortioxetine is an antidepressant for the treatment of major depressive disorder. Vortioxetine’s mechanism of action is not fully understood. Vortioxetine binds with high affinity to the serotonin transporter and its antidepressant actions are believed to be secondary to enhancing serotonin in the central nervous system through inhibition of reuptake. Vortioxetine also displays binding affinities to other serotonin (5-HT) receptors, including 5-HT3, 5-HT1A, and 5-HT7. Due to multimodal neurotransmitter enhancer profile, it has been suggested that it might need lesser receptor occupancy rate for clinical trials than other selective serotonin reuptake inhibitors and selective norepinephrine reuptake inhibitors. Since vortioxetine is an agonist and antagonist of multiple serotonin receptors, potential interactions may occur with other medications that alter the serotonergic pathways. There is an increased risk of serotonin syndrome when vortioxetine is used in combination with other serotonergic agents.

Ospemifene (commercial name Osphena produced by Shionogi) is anoral medication indicated for the treatment of dyspareunia – pain during sexual intercourse – encountered by some women, more often in those who are post-menopausal. Ospemifene is a selective estrogen receptor modulator (SERM) that selectively binds to estrogen receptors and either stimulates or blocks estrogen's activity in different tissue types. It has an agonistic effect on the endometrium. It’s building vaginal wall thickness which in turn reduces the pain associated with dyspareunia. Dyspareunia is most commonly caused by "vulval and vaginal atrophy”.

Dabrafenib is a selective, orally bioavailable inhibitor of Mutant BRAF protein kinase with potential antineoplastic activity. Dabrafenib inhibits BRAF kinases with in vitro IC50 values of 0.65, 0.5, and 1.84 nM for BRAF V600E, BRAF V600K, and BRAF V600D enzymes, respectively. Dabrafenib also inhibits wild-type BRAF and CRAF kinases with IC50 values of 3.2 and 5.0 nM. BRAF belongs to the the raf/mil family of serine/threonine protein kinases and plays a role in regulating the MAP kinase/ERKs signaling pathway, which may be constitutively activated due to BRAF gene mutations. Mutations in BRAF are associated with increased growth and proliferation of cancer cells. By inhibiting BRAF kinase dabrafenib negatively regulates the proliferation of tumor cells which contain a mutated BRAF gene. Dabrafenib (in combination with trametinib or alone) is indicated for the treatment of unresectable or metastatic melanoma with BRAF V600E mutation
