Pafenolol is a beta 1 selective adrenoceptor blocker that was studied in phase I clinical trial in Sweden for the treatment of arrhythmia. However, this study was discontinued.

Oxodipine is a dihydropyridine calcium channel blocker that has been developed by IQB as an antihypertensive agent. Experiments on dogs have shown that oxodipine exerted a relatively specific action on blood vessels without significant intrinsic negative chronotropic properties. in addition, in Europe, the drug was involved in phase III clinical trials in and in phase II for the treatment of Hypertension. Besides, oxodipine was studied for the treatment of ischaemic heart disorders. However, these studied were discontinued.

Selonsertib, also known as GS-4997, is a small-molecule inhibitor of apoptosis signal-regulating kinase 1 (ASK1), which promotes inflammation, apoptosis and fibrosis in settings of increased oxidative stress associated with NASH pathogenesis. GS-4997 prevents the production of inflammatory cytokines, down-regulates the expression of genes involved in fibrosis, suppresses excessive apoptosis and inhibits cellular proliferation. GS-4997 is currently being evaluated in an ongoing Phase 2 study in patients with NASH and moderate to severe liver fibrosis.

O-Desmethyl tramadol (O-Desmethyltramadol, O-DSMT) is a metabolite of tramadol. O-Desmethyltramadol is an opioid analgesic and the main active metabolite of tramadol. (+)-O-Desmethyltramadol is the most important metabolite of tramadol produced in the liver after tramadol is consumed. This metabolite is considerably more potent as a μ-opioid agonist than the parent compound. O-desmethyl tramadol, inhibits 5-hydroxytryptamine type 2C receptors expressed in xenopus oocytes. O-desmethyl tramadol inhibits functions of M(1) receptors but has little effect on those of M(3) receptors. O-desmethyl tramadol has been widely used clinically and has analgesic activity.

Enecadin (NS 7 or ZK 228326) is a voltage-dependent sodium and calcium channel blocker. Enecadin is a neuroprotective agent demonstrated efficacy in animal models of ischemic injury of brain, spinal cord and retina. Enecadin was undergoing phase II development in stroke with PAION in Germany. Enecadin development has been discontinued.

IRTEMAZOLE is a uricosuric agent exhibiting a rapid uricosuric effect in normouricemic as well as in hyperuricemic persons.

Mocimycin (also known as kyrromycin) was isolated from Streptomyces ramocissimus and tested in vitro against wide range of bacterias. Although having showed good results, drug did not enter clinical trials. Mocimycin acts by binding tightly and specifically to bacterial EF-Tu. Upon administration the antibiotic prevents EF-Tu-GDP from leaving the ribosome and thus inhibits bacterial protein synthesis. Nowadays, the antibiotic is mainly used to study bacterial protein synthesis at the level of elongation factor EF-Tu-GDP release.
