LASMIDITAN is a serotonin (5-HT) receptor agonist without vasoconstrictor activity, which selectively binds to the 5-HT(1F) receptor subtype. It is under development for the treatment of migraine.

Tafenoquine is anti-malaria drug originated in Walter reed army institute of research and developed by GSK and 60 Degrees Pharmaceuticals. In 2018 United States Food and Drug Administration (FDA) approved single dose tafenoquine for the radical cure (prevention of relapse) of Plasmodium vivax malaria. Tafenoquine, an 8-aminoquinoline antimalarial, is active against all the stages of Plasmodium species that include the hypnozoite (dormant stage) in the liver. Studies in vitro with the erythrocytic forms of Plasmodium falciparum suggest that tafenoquine may exert its effect by inhibiting hematin polymerization and inducing apoptotic like death of the parasite. In addition to its effect on the parasite, tafenoquine causes red blood cell shrinkage in vitro. Tafenoquine is active against pre-erythrocytic (liver) and erythrocytic (asexual) forms as well as gametocytes of Plasmodium species that include P. falciparum and P. vivax. The activity of tafenoquine against the pre-erythrocytic liver stages of the parasite, prevents the development of the erythrocytic forms of the parasite.

Prucalopride is a novel enterokinetic compound and is the first representative of the benzofuran class. Prucalopride is a potent, selective and specific serotonin 5-HT4 receptor (5-HT4-R) agonist. Prucalopride (Resolor®), a highly selective serotonin 5-HT4 receptor agonist, is indicated in the European Economic Area for the treatment of adults with chronic idiopathic constipation (CIC) in whom laxatives have failed to provide adequate relief.

Ribociclib, also known as LEE011, is an orally available cyclin-dependent kinase (CDK) inhibitor targeting cyclin D1/CDK4 and cyclin D3/CDK6 cell cycle pathway, with potential antineoplastic activity. CDK4/6 inhibitor LEE011 specifically inhibits CDK4 and 6, thereby inhibiting retinoblastoma (Rb) protein phosphorylation. Inhibition of Rb phosphorylation prevents CDK-mediated G1-S phase transition, thereby arresting the cell cycle in the G1 phase, suppressing DNA synthesis and inhibiting cancer cell growth. Overexpression of CDK4/6, as seen in certain types of cancer, causes cell cycle deregulation. Ribociclib is in phase III clinical trials by Novartis for the treatment of postmenopausal women with advanced breast cancer. Phase II clinical trials are also in development for the treatment of liposarcoma, ovarian cancer, fallopian tube cancer, peritoneum cancer, endometrial cancer, and gastrointestinal cancer. Preregistration for Breast cancer (First-line therapy, Combination therapy, Late-stage disease) in the USA (PO) in November 2016.

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.

Solifenacin is a competitive muscarinic acetylcholine receptor antagonist. The binding of acetylcholine to these receptors, particularly the M3 receptor subtype, plays a critical role in the contraction of smooth muscle. By preventing the binding of acetylcholine to these receptors, solifenacin reduces smooth muscle tone in the bladder, allowing the bladder to retain larger volumes of urine. It is FDA approved for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and urinary frequency. Common adverse reactions include constipation, Xerostomia. Inhibitors of CYP3A4 may increase the concentration of Solifenacin. Vice versa, CYP3A4 Inducers decrease concentration.

Frovatriptan succinate (trade name Frova) is a selective 5-hydroxytryptamine1 (5-HT1B/1D) receptor subtype agonist, and is used for the treatment of migraine attacks with or without aura in adults. Frovatriptan has no significant effects on GABAA mediated channel activity and has no significant affinity for benzodiazepine binding sites. Frovatriptan is believed to act on extracerebral, intracranial arteries and to inhibit excessive dilation of these vessels in migraine. Serious but rare cardiac events have been reported in patients with risk factors predictive of coronary artery disease (CAD). These include coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia and ventricular fibrillation.

Abacavir is a nucleoside reverse transcriptase inhibitor used for treatment of HIV infection (either alone or in combination with other antiviral drugs). It was shown that abacavir exerts its antiviral activity through its active metabolite, carbovir triphosphate. Carbovir triphosphate is a guanine analogue and a potent and selective inhibitor of viral reverse transcriptases. Upon administration, abacavir is first converted to abacavir monophosphate by ADK, then the monophosphate is deaminated to carbovir monophosphate, which is then anabolized by cellular kinases to carbovir diphosphate and then finally to carbovir triphosphate. Abacavir causes hypersensitivity reaction in patients with HLA-B*57:01 allele.
