(+)-alpha-Dihydrotetrabenazine (HTBZ) is an active component of tetrabenazine. Tetrabenazine is a mixture of closely-related compounds (isomers) and is readily metabolized in the human body to HTBZ and related isomers. Tetrabenazine is a drug for the symptomatic treatment of hyperkinetic movement disorder and is marketed under the trade names Nitoman in Canada and Xenazine in New Zealand and some parts of Europe, and is also available in the USA as an orphan drug. (+)-alpha-Dihydrotetrabenazine and related benzo[a]quinolizines have been labeled with tritium and carbon-11 radioisotopes and used for in vitro and in vivo studies of the VMAT2 in animal and human brain. Adeptio Pharmaceuticals is developing alpha-dihydrotetrabenazine (HTBZ) for the treatment of neurological disorders. It acts by inhibiting vesicular monoamine transporter 2 (VMAT2), thereby blocking the transport of dopamine into axon terminals or into storage vesicles.

Acalabrutinib, also known as ACP-196, is a novel irreversible second-generation Bruton’s tyrosine kinase (BTK) inhibitor, which prevents the activation of the B-cell antigen receptor (BCR) signaling pathway and that, was rationally designed to be more potent and selective than ibrutinib. This drug in clinical trials phase III for treatment the treatment of relapsed chronic lymphocytic leukemia. Also in combination with others drugs, Acalabrutinib in phase II of clinical trials for the treatment Glioblastoma Multiforme, Mantle Cell Lymphoma, Squamous Cell Carcinoma of the Head and Neck, Rheumatoid Arthritis and some others.

Etelcalcetide (formerly velcalcetide, trade name Parsabiv) is a calcimimetic drug for the treatment of secondary hyperparathyroidism in patients undergoing hemodialysis. Etelcalcetide was approved (trade name Parsabiv) for the treatment of secondary hyperparathyroidism (HPT) in adult patients with chronic kidney disease (CKD) on hemodialysis in February, 2017. Etelcalcetide is a synthetic peptide calcium-sensing receptor agonist. It allosterically modulates the calcium-sensing receptor (CaSR). Etelcalcetide binds to the CaSR and enhances activation of the receptor by extracellular calcium. Activation of the CaSR on parathyroid chief cells decreases PTH secretion.

Ertugliflozin (PF-04971729) is a potent and selective sodium-dependent glucose cotransporter 2 (SGLT2) inhibitor incorporating a unique dioxa-bicyclo[3.2.1]octane (bridged ketal) ring system. SGLT2 has become an important therapeutic target and several SGLT2-selective inhibitors are either approved or in clinical development for the management of blood glucose in patients with type 2 diabetes. Ertugliflozin demonstrated robust urinary glucose excretion in rats and an excellent preclinical safety profile. It was announced that FDA and EMA filing acceptances of three marketing applications for ertugliflozin-containing medicines for adults with type 2 diabetes.

Enasidenib, aslo known as AG-221 and CC-90007, is a potent and selective IDH2 inhibitor with potential anticancer activity (IDH2 = Isocitrate dehydrogenase 2). The mutations of IDH2 present in certain cancer cells result in a new ability of the enzyme to catalyze the NAPH-dependent reduction of α-ketoglutarate to R(-)-2-hydroxyglutarate (2HG). The production of 2HG is believed to contribute to the formation and progression of cancer. The inhibition of mutant IDH2 and its neoactivity is therefore a potential therapeutic treatment for cancer. Enasidenib is an orally available, selective, potent inhibitor of the mutated IDH2 protein, making it a highly targeted investigational medicine for the potential treatment of patients with cancers that harbor an IDH2 mutation. Enasidenib has received orphan drug and fast track designations from the U.S. FDA. Enasidenib mesylate is in phase II clinical trials for Solid tumours and phase III clinical trials for the treatment of acute myeloid leukaemia.

Neratinib (HKI-272) is a pan-HER inhibitor, this irreversible tyrosine kinase inhibitor binds and inhibits the tyrosine kinase activity of epidermal growth factor receptors, EGFR (or HER1), HER2 and HER4, which leads to reduced phosphorylation and activation of downstream signaling pathways. Neratinib is a modified form of the discontinued compound pelitinib, and was originally being develoAdditionally, phase II development of oral neratinib as a neoadjuvant therapy for breast cancer, as a second-line therapy for non-small cell lung cancer, and for other solid tumours is also in progress in numerous countries worldwide. ped by Wyeth (later Pfizer). Oral neratinib is awaiting approval as an extended adjuvant therapy for breast cancer in the EU and in the US. Blocking HER2 function by a small molecule kinase inhibitor, such as neratinib, represents an attractive alternate strategy for the growth inhibition of HER2-positive tumours.

Niraparib (MK-4827) displays excellent PARP 1 and 2 inhibition. Inhibition of PARP in the context of defects in other DNA repair mechanisms provide a tumor specific way to kill cancer cells. Niraparib is in development with TESARO, under licence from Merck & Co, for the treatment of cancers (ovarian, fallopian tube and peritoneal cancer, breast cancer, prostate cancer and Ewing's sarcoma). Niraparib was characterized in a number of preclinical models before moving to phase I clinical trials, where it showed excellent human pharmacokinetics suitable for once a day oral dosing, achieved its pharmacodynamic target for PARP inhibition, and had promising activity in cancer patients. It is currently being tested in phase 3 clinical trials as maintenance therapy in ovarian cancer and as a treatment for breast cancer.

Abemaciclib, previously known as LY2835219, is a potent and selective inhibitor of cyclin-dependent kinases: CDK4 and CDK6, developed by Eli Lilly, which is in clinical trial phase III for the treatment of breast cancer and non-small cell lung cancer (NSCLC) and in phase II for investigation of its treatment glioblastoma and melanoma.
