Prazitone (also known as AGN-511) is a barbiturate derivative patented by Aspro-Nicholas Ltd. as a non-sedating anxiolytic and antidepressant

Bromebric Acid (Cytembena) is a derivative of bromoacrylic acid with cytostatic and antineoplastic activity. Chemical structure of Bromebric Acid is not related to any previous antineoplastic agent. In animal tumor screens, Jelinek and Semonsky noted antineoplastic activity of Cytembena against sarcoma 180, atlenocarcinoina of the lactic gland in mice, Ehrlich’s ascitic carcinoma, Yoshida’s ascitic sarcoma, and Zojdeln’s heap

Monophosphothiamine is thiamine derivative used for the treatment of neuritis, polyneuritis, asthenic conditions (weakness), as an additional remedy for chronic blood circulation insufficiency, chronic gastritis accompanied by motor and secretory disorders functions of the stomach. Monophosphothiamine underwent metabolic phosphorylation to active metabolite thiamine pyrophosphate, that acts as a coenzyme in the different metabolic process.

Dexproxibutene is an experimental agent structurally related to propoxyphene. It is an analgesic agent. Dexproxibutene is not very effective in rheumatoid arthritis pain relief. It is intermediate in effectiveness between distalgesic, codis, aspirin and placebo.

Drobuline is a potent cardiac depressant (anti-arrhythmic) agent, which has been found to be effective against ventricular arrhythmias in dogs. This compound is a racemic mixture having a single center of optical activity. The two isomers of drobuline were found to be equally potent in converting cardiac arrhythmias in dogs after intravenous administration. The major route of biotransformation of drobuline in the dog was shown to be conjugation with glucuronic acid.

GDC-0994 (RG7842) is a selective inhibitor of ERK1/2, also known as extracellular-signal-regulated kinases. Daily, oral dosing of GDC-0994 results in significant single-agent activity in multiple in vivo cancer models, including KRAS-mutant and BRAF-mutant human xenograft tumors in mice. GDC-0994 neither increases nor decreases phospho-ERK, suggesting that different ERK inhibitors have alternative mechanisms of action with respect to feedback signaling. GDC-0994 is currently advancing in a Phase 1 trial in patients with solid tumors.

Inaperisone is a pyrrolidinopropiophenone derivative patented by Japanese pharmaceutical company Hokuriku Pharmaceutical Co. as muscle-relaxant and antispasmodic agent.

Idazoxan is an alpha2 receptor antagonist which also shows activity at imidazoline I1 and I2 receptors and modulates the release of dopamine. Idazoxan was in phase II development in the US. Later the development of idazoxan for schizophrenia was discontinued. It was also in clinical trials for cognition disorders in United Kingdom, and was also discontinued. Idazoxan is used in scientific research as a tool for the study of alpha 2-adrenoceptors.

AKN-028 is an orally bioavailable protein tyrosine kinase inhibitor for FMS-related tyrosine kinase 3 (IC(50)=6 nM) and stem cell factor receptor (SCFR; KIT), with potential antineoplastic activity. FLT3/KIT kinase inhibitor AKN-028 binds to and inhibits both the wild-type and mutated forms of FLT3 and SCFR. Akinion Pharmaceuticals is developing AKN-028 for the treatment of acute myeloid leukaemia. AKN-028 is presently undergoing investigation in a phase I/II study.
