Masilukast (ZD 3523) is an antagonist of leukotriene D4 (LTD4). It opposes LTD4-induced bronchoconstriction. It was being developed for the treatment of asthma.

FLUDOREX is an antiemetic and anorexic agent.

Tolpronine possesses significant analgesic properties in mice by the subcutaneous, oral and intraperitoneal routes. The compound is most active subcutaneously, having approximately 20 times the activity of metamizolum on a weight for weight basis. In addition to its analgesic activity, tolpronine also possesses local anesthetic properties, being approximately 1.5 times as active as procaine hydrochloride in the guinea pig intracutaneous wheal test. It is, however, at least twice as toxic by the subcutaneous route. It has an anti-acetylcholine action on the isolated guinea-pig ileum. Excessively large amounts constipate normal mice; a weak spasmolytic effect is seen in the isolated guinea-pig ileum and rabbit duodenum. The jejunum of the anesthetized cat shows a spasmogenic effect. Chronic administration to rats and rabbits caused a reduction in the growth rate of rats.

Tanzisertib (CC-930) is a potent and selective inhibitor of JNK1/JNK2/JNK3 with IC50 values of 61 nM, 7 nM and 6 nM respectively. Tanzisertib had been in phase II clinical trials for the treatment of idiopathic pulmonary fibrosis and discoid lupus erythematosus. But this research was discontinued in 2012. In 2011, the compound was granted orphan drug designation in the U.S. and the E.U. for the treatment of idiopathic pulmonary fibrosis. The compound was co-developed by Celgene and Ligand.

Rifamides (NSC-143418) are drugs used in the treatment of tuberculosis. They also have immunosuppressive activity, the exact mechanism of which is still unknown, although the ability of rifamides to inhibit tumor necrosis factor (TNF)-induced NF-kB activation may be associated with it. A variety of rifamide analogues exist, such as rifamycin B, rifapentine, rifamycin SV, rifabutin and rifampicin.

Tropirine is an antihistaminic, respiratory, anticholinergic agent.

Narlaprevir (formerly SCH 900518), a NS3 protease inhibitor is being developed by R-Pharm for the treatment of a chronic hepatitis C (genotype 1). Narlaprevir is a potent inhibitor of hepatitis C virus (HCV) NS3 protease with a Ki of 7 ± 1 nM and a 90% inhibitory concentration (IC90) of ∼28 ng/ml for HCV genotype 1 replicon in vitro. Narlaprevir successfully passed extensive pre-clinical and clinical trials in Schering-Plough Research Institute (USA) and in a variety of clinical centers of Europe, USA and Russia. Based on clinical findings R-Pharm obtained a registration certificate for Arlansa (Narlaprevir) ЛП-003622 dd 12.05.2016 issued by Ministry of Healthcare of the Russian Federation.

Atagabalin, also known as PD-0200390, was studied in phase II clinical trials in patients with primary insomnia, but this trial was discontinued because of the unsatisfied results. Atagabalin is a ligand to the α(2)δ subunit of voltage-sensitive calcium channels
