Vapendavir (BTA-798) is an orally active capsid-binding inhibitor. It is a potent, orally bioavailable, broad spectrum inhibitor of the large group of HRVs. Vapendavir binds tightly to VP1s canyon and disrupts the ability of the capsid to bind to a specific cell surface receptor. This further inhibits the release of the viral RNA into the cell cytoplasm during the viral uncoating process (removing the lipid bilayer), thereby disrupting viral replication. Vapendavir is designed to be dosed orally. Vapendavir is in phase II clinical trials for the treatment of rhinovirus-induced aggravation of pre-existing asthma or COPD. Vapendavir has shown significant results in proof-of-concept studies. Thus far, from the Phase 1/2 studies conducted, vapendavir has demonstrated a desirable clinical pharmacology profile with high bioavailability, linear pharmacokinetic profile, remained unaffected by concomitant medications, and was not exclusively metabolized.

Cletoquine is a metabolite of a disease-modifying anti-rheumatic and antimalarial drug hydroxychloroquine. It is produced by oxidative N-deethylation of hydroxychloroquine.

FLOPRISTIN is one of the components of the experimental drug NXL103 (XRP 2868), along with linopristin. Both are semi-synthetic streptogramin antibiotics derived from the Streptomyces genus. NXL103 has a spectrum of antibacterial activity that indicates it has the potential to be effective in the treatment of skin and skin structure infections, including those caused by methicillin-resistant Staphylococcus aureus, as well as community-acquired pneumonia. NXL103 has completed Phase II trials.

Derpanicate is cholesterol inhibitor. It was developed for the treatment of hyperlipidaemia. Preregistration was discontinued in Italy and Switzerland.

Levopropylcillin – is a penicillin derivative, L-enantiomer of antibiotic Propicillin. Levopropylcillin properties are similar to benzylpenicillin particularly used in streptococcal infections, not resistant to penicillinase. Levopropylcillin is acid resistant and can be used orally as the potassium salt.

Mebiquine is an antidiarrheal and antihelmintic compound.

Dersalazine is a locally-acting compound. It is a potent platelet activating factor (PAF)-antagonist. Dersalazine inhibited IL-1beta or TNF-alpha production in THP-1 or U937 cells, respectively. Dersalazine sodium reduced colonic proinflammatory cytokines IL-1b, IL-6, and IL-17 in dextran sodium sulphate (DSS)–induced colitis. After oral administration, dersalazine sodium is mostly unabsorbed until it reaches the large bowel where the azo bond is reduced by bacteria releasing the active compound. Dersalazine had been in phase I clinical trial for the treatment of ulcerative colitis. No serious adverse reactions were detected in clinical trial. However, no recent development has been reported.

Iomethin I-131 is radioiodinated quinoline derivative with potential tumor localizing activity. In animal models, Iomethin I-131 administrations lead to regression of the malignant melanoma and its metastases.

Tropabazate is a narcosis potentiator, tranquilliser.
