ISOCROMIL, a chromone, is an antiallergic agent. It is a mediator release inhibitor used for the treatment of passive cutaneous anaphylaxis and as an anti-asthmatic.

Dexpemedolac is long-acting non-narcotic analgesic. Dexpemedolac exhibited potent analgesic effects against chemically induced pain in rats and mice and against inflammatory pain in rats. Dexpemedolac differed from standard nonsteroidal anti-inflammatory drugs (NSAIDs) in that the doses, which produced analgesia were much lower than those required for either anti-inflammatory or gastric irritant effects. The common to the NCAIDs class actions are antipyresis and inhibitory effects on platelet aggregation. In yeast-induced hyperthermic rats, dexpemedolac exhibited antipyretic actions, whereas the drug did not affect body temperature in normothermic animals. Aggregation of human platelets was inhibited by high concentrations of dexpemedolac.

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

IRLOXACIN, a fluorinated quinolone derivative, is an antibacterial agent with proved activity against both gram-positive and gram-negative bacteria.

Adekalant (H 345/52) is a new antiarrhythmic compound with low proarrhythmic activity. H 345/52 concentration-dependently blocked HERG-carried currents with an IC50 of 230 nM. H 345/52 preferentially bound to the open channel with unusually rapid kinetics and was trapped by channel closure. Voltage-independent behavior of H 345/52 was observed during both square-pulse and action potential clamp protocols. It is proposed that block of IKr is the principal mechanism by which H 345/52 delays repolarization in human myocardium. H 345/52 blocks I(Kr) with high potency and I(Ca) with somewhat lower potency and was found to delay ventricular repolarisation without substantially increasing temporal or spatial dispersion and without inducing early after-depolarisations or TdP.

Iosumetic Acid is a triiodoaminoisophthalic acid derivative patented by Schering A.-G. as contrast medium for direct and indirect lymphography.

Iotrizoic Acid is acylated amino acid derivative patented by Swiss pharmaceutical company Cilag-Chemie A.-G. as x-ray contrasting agent

Evatanepag (CP-533,536) is a prostaglandin E2 EP2 receptor agonist. It stimulates new bone formation on trabecular, endocortical, and periosteal surfaces and enhances fracture healing. Evatanepag was under development with Pfizer as a bone formation stimulant for therapeutic use in the healing of fractures.

Iobutoic Acid is a Triiodo-hydroxybenzamide derivative patented by Laboratoires Andre Guerbet as x-ray contrast media in cholecystography and as a choleretic agent.

Rupintrivir is a peptide aldehyde that targets the human rhinovirus (HRV) 3C proteinase enzyme and has the potential for the treatment of the common cold. Rupintrivir is derived from AG-6084 - in order to develop human rhinovirus 3C protease inhibitors with improved pharmacological properties, Agouron replaced the backbone amide moiety of the series which yielded AG-6084, with a ketomethylene isostere. A phase II efficacy study has been completed in healthy patients infected with the rhinovirus. Ruprintrivir was well tolerated; blood-tinged mucus and nasal passage irritation were the most common adverse effects reported. Pharmacokinetic analysis of plasma and nasal ruprintrivir concentrations revealed intranasal drug residence with minimal systemic absorption. The fact that rupintrivir is active against noroviruses belonging to genogroup I (Norwalk virus), genogroup V (murine norovirus), and the recombinant 3C-like protease of a GII norovirus suggests that the drug exerts cross-genotypic anti-norovirus activity and will thus most likely be effective against the clinically relevant human norovirus strains. Rupintrivir is also a high affinity inhibitor of Enterovirus-71 3C protease.
