Cannabidiol is the major nonpsychoactive ingredient in cannabis. Cannabidiol demonstrates a range of effects that may be therapeutically useful, including anti-seizure, antioxidant, neuroprotective, anti-inflammatory, analgesic, anti-tumor, anti-psychotic, and anti-anxiety properties. Exact mechanism of action of cannabidiol is not known, but may include effects on the orphan G-protein-coupled receptor GPR55; the transient receptor potential of vanilloid type-1 channel; the 5-HT1a receptor; and the α3 glycine receptors. GW Pharmaceuticals successfully developed the world’s first prescription medicine derived from the cannabis plant, Sativex® (buccal spray containing delta-9-tetrahydrocannabinol and cannabidiol) now approved in over 29 countries outside of the United States for the treatment of spasticity due to Multiple Sclerosis. GW Pharmaceuticals is developing Epidiolex® (a liquid formulation of pure plant-derived cannabidiol) for certain rare and severe early-onset, drug-resistant epilepsy syndromes.
Elcometrine (Segesterone acetate, Nestorone) is a steroidal progestin which is used as a hormonal contraceptive and as a treatment of endometriosis. Upon oral administration, Nestorone undergoes rapid metabolism and inactivation. Several clinical trials have been performed with Nestorone administered via subdermal implants.

Conditions:

Migalastat (Galafold)-a small molecule drug developed by Amicus Therapeutics that restores the activity of specific mutant forms of α-galactosidase-has been approved for the treatment of Fabry disease in the EU in patients with amenable mutations. Migalastat attaches to certain unstable forms of alpha-galactosidase A, stabilising the enzyme. This allows the enzyme to be transported into areas of the cell where it can break down GL-3. Under the trade name Galafold (formerly known as Amigal), Migalastat is used to treat patients aged 16 years or over with Fabry disease. Because the number of patients with Fabry disease is low, the disease is considered ‘rare’, and the US Food and Drug Administration (FDA) assigned Galafold orphan drug status in 2004, and the European Committee for Medicinal Products for Human Use (CHMP) followed in 2006.

Conditions:

Tafenoquine is anti-malaria drug originated in Walter reed army institute of research and developed by GSK. The drug is being evaluated in phase 3 clinical trials for treatment and prophylaxis of malaria. Tafenoquine works by induction of mitochondrial dysfunction through the inhibition of cytochrome c reductase (respiratory complex III) with a decrease in the oxygen consumption rate and depolarization of mitochondrial membrane potential.

Conditions:

Tecovirimat (ST-246) is a low-molecular-weight compound (molecular weight = 376), that is potent (concentration that inhibited virus replication by 50% = 0.010 microM), selective (concentration of compound that inhibited cell viability by 50% = >40 microM), and active against multiple orthopoxviruses, including vaccinia, monkeypox, camelpox, cowpox, ectromelia (mousepox), and variola viruses. The antiviral activity is specific for orthopoxviruses and the compound does not inhibit the replication of other RNA- and DNA-containing viruses or inhibit cell proliferation at concentrations of compound that are antiviral. ST-246 targets vaccinia virus p37, a viral protein required for envelopment and secretion of extracellular forms of virus. The compound is orally bioavailable and protects multiple animal species from lethal orthopoxvirus challenge. rug substance and drug product processes have been developed and commercial scale batches have been produced using Good Manufacturing Processes (GMP). Human phase I clinical trials have shown that ST-246 is safe and well tolerated in healthy human volunteers. Based on the results of the clinical evaluation, once a day dosing should provide plasma drug exposure in the range predicted to be antiviral based on data from efficacy studies in animal models of orthopoxvirus disease.
Talazoparib (BMN 673) demonstrates excellent potency, inhibiting PARP1 and PARP2 enzyme activity. It inhibits PARP-mediated PARylation in a whole-cell assay and prevents proliferation of cancer cells carrying mutant BRCA1/2. Talazoparib is orally available, displaying favorable pharmacokinetic properties and remarkable antitumor efficacy in the BRCA1 mutant MX-1 breast cancer xenograft model following oral administration as a single-agent or in combination with chemotherapy agents such as temozolomide and cisplatin. Medivation (a subsidiary of Pfizer) is developing talazoparib (MDV 3800, formerly BMN 673 and LT 673) for the treatment of genetically defined cancers.

Sarecycline (SC1401, WC3035) is a novel, once-daily, tetracycline-derived compound being developed by Paratek Pharmaceuticals and Allergan (previously Actavis) for use in the treatment of acne and rosacea. In preclinical studies, Sarecycline possesses favorable anti-inflammatory activity, plus narrow-spectrum antibacterial activity relative to other tetracycline-derived molecules. Sarecycline has been used in Phase III clinical trials studying the treatment of Acne Vulgaris. The primary objective was to evaluate the efficacy and safety of oral Sarecycline 1.5 mg/kg per day compared to placebo in treating inflammatory acne lesions in subjects with moderate to severe acne. Sarecycline was statistically significantly superior to placebo with respect to primary efficacy endpoints. The most common adverse events (>2%) reported in the sarecycline group were nausea (3.2%), nasopharyngitis (2.8%), and headache (2.8%). The rate of discontinuation due to adverse events among sarecycline-treated patients in the two studies combined was 1.4%.
