Daprodustat (GSK1278863) is a low nanomolar hypoxia-inducible factor (HIF) prolyl hydroxylase (PHD) inhibitor, that increases HIF stability and action. In preclinical studies, Daprodustat stabilizes HIFα in cell lines, resulting in the production of increased levels of erythropoietin (EPO). In normal mice, a single dose of Daprodustat induced significant increases in circulating plasma EPO but only minimal increases in plasma vascular endothelial growth factor (VEGF-A) concentrations. Daprodustat significantly increased reticulocytes and red cell mass parameters in pre-clinical species following once-daily oral administration and has demonstrated an acceptable nonclinical toxicity profile supporting continued clinical development. In a phase 1 study, Daprodustat was well tolerated and increased erythropoietin (EPO) levels in apparently healthy individuals proportional to dose. In phase 2a studies in non–dialysis-dependent chronic kidney disease (NDD CKD) and end-stage renal disease Daprodustat 4-10 mg once-daily produced the dose-dependent increase in hemoglobin relative to placebo. The Phase III programme for the drug includes two studies evaluating its safety and efficacy compared to recombinant human erythropoietin in dialysis-dependent subjects with anemia associated with CKD (ASCEND-D) and in non-dialysis dependent patients with the condition (ASCEND-ND).

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.

Dimiracetam is a nootropic drug of the racetam family. Dimiracetam inhibited the NMDA-induced increase of [3H]D-Asp release from hippocampal synaptosomes. The increased potency and longer duration of action of dimiracetam, together with the potential cognition enhancing property makes it a very promising and safe for the treatment of neuropathic pain conditions for which there are very limited therapeutic options. Dimiracetam is in Phase II clinical trials for the treatment of HIV-associated pain and in phase I clinical trials for the treatment of osteoarthritis pain.

SKF83959 is a benzodiazepine derivative which acts as an agonist of D1 receptor. Activation of D1 receptors by SKF83959 fails to stimulate adenylyl cyclase and inhibits the stimulation of adenylyl cyclase induced by dopamine but stimulates phosphatidylinositol 4,5-biphosphate hydrolysis in membranes of frontal cortex. SKF83959 was identified as a specific agonist for the heteromer D1/D2 complex. SKF83959 elicit anti-parkinsonism effects in monkeys and rodents. In lower concentrations, SKF83959 inhibits serotonin, norepinephrine and dopamine transporters and is an allosteric regulator of sigma 1 receptor. The compound has demonstrated activity in a preclinical model of depression.

SB-228357 was originally developed by scientists at Smith Kline Beecham (now merged with Glaxo Welcome to form GlaxoSmithKline). SB-228357 was identified as an antagonist of the serotonin receptors 5-HT2a/b/c with the highest affinity exhibited towards the 5-HT2C receptor. SB-228357 was identified for preclinical development as a treatment for depression, anxiety, and cataplexy but has not progressed beyond animal trials.

Epristeride is a steroid 5-alpha-reductase inhibitor developed for the treatment of prostatic hyperplasia and acne. The drug reached phase III clinical trial for hyperplasia in the UK, the US and Japan, however, the current status of the drug is unknown.
