ITROCINONIDE is a synthetic corticosteroid which showed no signs of systemic activity (cortisol depression).

ilofungin is a narrow spectrum antimycotic patented by a pharmaceutical company Eli Lilly and Co in 1981. Cilofungin is particularly active against the opportunistic fungal pathogen Candida albicans. Cilofungin action is exerted through inhibition of the synthesis of (1,3)-beta-glucan, an essential cell wall component, it invades a fungus' ability to synthesize cell walls.

As a narcotic antagonist similar in action to naloxone, DIPRENORPHINE is used to remobilize animals after analgesia by super-potent opioid analgesics such as etorphine and carfentanil. It is not used in humans. Diprenorphine binds approximately equally to the three subtypes of opioid receptors (mu, delta, and kappa) and antagonizes them. This compound belongs to the class of organic compounds known as phenanthrenes and derivatives. These are polycyclic compounds containing a phenanthrene moiety, which is a tricyclic aromatic compound with three non-linearly fused benzene. The therapeutic efficacy of many other compounds can be decreased when used in combination with Diprenorphine (54 compounds mentioned on www.drugbank.ca).

Pleuromulin (pleuromulitin) is a natural antibiotic isolated from Basidiomycete Pleurotus. Pleuromulitin exhibits activity mainly against gram-positive bacteria including S. aureus, Klebasiella pneumoniae and Bacillus Subtilis. Pleuromulin is an organic compound which is not reported to be used in as a drug however its derivatives have been used in treatment of infections. The first pleuromulitin that was approved in 1979 for use in veterinary medicine was semi-synthetic derivative tiamulin. Semisynthetic pleuromutilin retapamulin (ALTABAX, GlaxoSmithKline) was the first approved for topical use in humans in 2007. Another derivative of pleuromulin, Lefamulin has been successfully tested in phase 1 clinical trial for systemic use in patients (Nabriva Therapeutics AG).

The natural tetrapeptide acetyl-N-Ser-Asp-Lys-Pro (AcSDKP also known as Goralatide) is generated from the N-terminus of thymosin-β4 through enzymatic cleavage by prolyl oligopeptidase (POP). AcSDKP regulation of proliferation of different cells is implicated in hematopoiesis and angiogenesis. This tetrapeptide present in almost all cells was recently detected at elevated concentrations in neoplastic diseases. However, previously reported in vitro and in vivo studies indicate that AcSDKP does not contribute to the pathogenesis of cancers. AcSDKP was in the phase II clinical trial for development of a new non-radioactive test for measuring glomerular filtration rate in patient with Chronic Kidney Disease. In addition, using mice models was concluded ,that AcSDKP might be an oral antifibrotic peptide drug that would be relevant to combating fibroproliferative kidney diseases such as diabetic nephropathy.

Ronipamil was developed as a verapamil analogue with a longer duration of action. However, it has much less calcium antagonist action than verapamil. Ronipamil has been tested for its ability to reduce ischaemia-induced arrhythmias in conscious rats. Compared to similar compounds, ronipamil was less effective and produced no statistically significant antiarrhythmic effects in rats. It had limited haemodynamic effects and no marked actions on blood pressure and heart rate. In another study, ronipamil prolonged survival time after traumatic shock and was shown to possess anti-shock potential. No information on current development of this drug is available.

Benzmalecene, an inhibitor of cholesterol biosynthesis, was studied for patients with hypercholesterolemia. Unfortunately, treatment was associated with undesirable side effects that prevented further using this drug in clinical.

Atropine-N-oxide hydrochloride is an alkaloid of the belladonna plants. It is the major metabolite of atropine. It is a competitive nonselective antagonist at central and peripheral muscarinic acetylcholine receptors.

Climazolam is a benzodiazepine derivative, developed by Hoffman-LaRoche. It was used in veterinary for anesthetizing animals.
