Nemorubicin, a doxorubicin derivative, is a DNA-intercalator, topoisomerase and RNA synthesis inhibitor that was undergoing development with Nerviano Medical Sciences (Nerviano MS; formerly Pharmacia Italia) for the treatment of solid tumours, specifically, the loco-regional treatment of primary liver tumours (hepatocellular carcinoma). The drug is active on tumors resistant to alkylating agents, topoisomerase II inhibitors and platinum derivatives. It works primarily through topoisomerase I inhibition. Of note, Nemorubicin is active in cells with upregulation of the nucleotide excision repair (NER) pathway, where current therapies fail. Nemorubicin is biotransformed in the liver into cytotoxic metabolites that may further contribute to render this drug highly active against primary liver tumors or liver metastases. Clinical trials were conducted in Europe, US and China with Nemorubicin given at different dose-schedules and by different routes of administration: as single agent by systemic IV route, oral route and by intra-hepatic artery (IHA) infusion alone or in combination with cisplatin.

Olmidine (also known as dl-mandelamidine) is an antihypertensive drug that has never been marketed. Information about the current use of this drug is not available.

Espatropate (UK 88060) is an antagonist of M3 muscarinic receptors. Espatropate is a bronchodilator with anticholinergic activity. It was undergoing preclinical development with Pfizer for the treatment of asthma.

Moxastine is a diarylmethane derivative with an antihistamine and anticholinergic activities.

Fenabutene controls pituitary activity.

Fenbenicillin (phenoxybenzylpenicillin) is an acid-stable, orally active penicillin. Fenbenicillin demonstrated antibacterial activity in patients suffering from streptococcal, pneumococcal, and penicillin-sensitive staphylococcal infections.

Fencibutirol is alpha-cyclohexylbutyric acid derivative. It exerts choleretic activity.

Pentorex (Modatrop) is phenylisopropylamine derivative. It is a central adrenergic stimulant drug related to phentermine, which is used as an anorectic to assist with weight loss. Pentorex is sympathomimetic agent.

Pentisomide is an agent structurally related to disopyramide. Pentisomide is a class-I antiarrhythmic agent with a marked effect on depolarization (action of class Ia and Ic) and on repolarization. Pentisomide dose-dependently inhibited ischaemia-reperfusion arrhythmia. Pentisomide had been in phase II clinical trial for the treatment of arrhythmias. The electrophysiologic effects of pentisomide were investigated after intravenous and oral application in patients with drug refractory atrioventricular nodal tachycardia and patients with orthodromic atrioventricular re-entrant tachycardia. If intravenous pentisomide did not prevent induction of the tachycardia, oral pentisomide was not effective either. Long-term treatment with pentisomide had to be discontinued because of possible side effects.

Acebrochol is a neuroactive steroid that may act as a sedative and hypnotic, through the mechanism of altering ligand-gated ion channels and cell surface receptors.
