Ivabradine (CORLANOR®) is a hyperpolarization-activated cyclic nucleotide-gated channel blocker that reduces the spontaneous pacemaker activity of the cardiac sinus node by selectively inhibiting the If-current, resulting in heart rate reduction at concentrations that do not affect other cardiac ionic currents. Specific heart-rate lowering with ivabradine (CORLANOR®) reduces myocardial oxygen demand, simultaneously improving oxygen supply. It has no negative inotropic or lusitropic effects, preserving ventricular contractility, and does not change any major electrophysiological parameters unrelated to heart rate.

Flibanserin is the first drug to be approved for hypoactive sexual desire disorder (HSDD) in premenopausal women by the FDA in August 2015. It was originally developed as an antidepressant medication by Boehringer Ingelheim, but showed lack of efficacy in trials and was further developed as a hypoactive sexual disorder drug by Sprout Pharmaceuticals. Flibanserin's mechanism of action is attributed to its high affinity for 5-HTA1 and 5-HTA2 receptors, displaying agonist activity on 5-HTA1 and antagonist on 5-HTA2, resulting in lowering of serotonin in the brain as well as an effect on increasing norepinephrine and dopamine neurotransmitters. Flibansetrin has high affinity for serotonin receptors in the brain: it acts as an agonist on 5-HT1A and an antagonist on 5-HT2A. In vivo, flibanserin binds equally to 5-HT1A and 5-HT2A receptors. However, under higher levels of brain 5-HT (i.e., under stress), flibanserin may occupy 5-HT2A receptors in higher proportion than 5-HT(1A) receptors. It may also moderately antagonize D4 (dopamine) receptors and 5-HT2B and 5-HTB2C. Its action on neurotransmitter receptors may contribute to reduction in serotonin levels and increase in dopamine and norepinephrine levels, all of which may play part in reward processing. Flibanserin is sold under the trade name Addyi and indicated for the treatment of premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD) as characterized by low sexual desire that causes marked distress or interpersonal difficulty.

Miltefosine is an anti-leishmanial agent. It is an alkyl phospholipids compound, was originally intended for breast cancer and other solid tumors. However, it could not be developed as an oral agent because of dose-limiting gastro-intestinal toxicity, and only a topical formulation is approved for skin metastasis. But Miltefosine showed excellent antileishmanial activity both in vitro and in experimental models. Miltefosine is effective in vitro against both promastigotes and amastigotes of various species of Leishmania and also other kinetoplastidae (Trypanosoma cruzi,T. brucei) and other protozoan parasites (Entamoeba histolytica, Acanthamoeba). Mechanism of action is unknown. It is likely to involve interaction with lipids (phospholipids and sterols), including membrane lipids, inhibition of cytochrome c oxidase (mitochondrial function), and apoptosis-like cell death. Miltefosine is approved for the treatment of Visceral leishmaniasis (due to Leishmania donovani), Cutaneous leishmaniasis (due to Leishmania braziliensis, Leishmania guyanensis, and Leishmania panamensis) and Mucosal leishmaniasis (due to Leishmania braziliensis).

Ledipasvir is an inhibitor of the Hepatitis C Virus (HCV) NS5A protein required for viral RNA replication and assembly of HCV virions. Approved in October 2014 by the FDA, ledipasvir and sofosbuvir (tradename Harvoni) are direct-acting antiviral agents indicated for the treatment of HCV genotype 1 with or without cirrhosis.

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.

Florbetaben F18 is a18F-labeled stilbene derivative used as a tracer for PET imaging of beta-amyloid deposits in the human brain. The F 18 isotope produces a positron signal that is detected by a PET scanner. 3H-florbetaben in vitro binding experiments reveal two binding sites (Kd of 16 nM and 135 nM) in frontal cortex homogenates from patients with AD. Binding of florbetaben F18 to beta-amyloid plaques in post-mortem brain sections from patients with AD using autoradiography correlates with both immunohistochemical and Bielschowsky silver stains. Florbetaben F 18 does not bind to tau or alpha-synuclein in tissue from patients with AD. Neither Neuraceq nor non-radioactive florbetaben F 19 bind to AT8 positive tau deposits in brain tissue from patients with frontotemporal dementia (FTD), using autoradiography and immunohistochemistry, respectively.

Suvorexant is a selective dual antagonist of orexin receptors OX1R and OX2R. It has been approved for the treatment of insomnia. The mechanism by which suvorexant exerts its therapeutic effect in insomnia is presumed to be through antagonism of orexin receptors. The orexin neuropeptide signaling system is a central promoter of wakefulness. Blocking the binding of wake-promoting neuropeptides orexin A and orexin B to receptors OX1R and OX2R is thought to suppress wake drive.

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.

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

Trametinib is a reversible and specific inhibitor of mitogen-activated protein kinase kinases MEK1 and MEK2 which are involved in a RAS/RAF/MEK/ERK signaling pathway and control cell growth, survival, and differentiation. By inhibiting MEK1 and MEK2 trametinib blocks dual phosphorylation of ERK1/2 and stops cell cycling. In addition, trametinib blocks BRAF pathway in the cells with BRAF V600E mutations. Trametinib (as a single agent and in combination with dabrafenib) is approved for the treatment of unresectable or metastatic melanoma with BRAF V600E or V600K mutations.
