Nadoxolol is a beta-adrenergic blocking agent and an antihypertensive drug.

Tefinostat (also known as CHR-2845) was developed as an innovative oral HDAC (histone deacetylase) inhibitor that selectively targets macrophages and monocytes – central cells of the innate immune system. Chroma Therapeutics develops tefinostat for the treatment of hematological and lymphoid malignancies. In addition, the drug is under investigation in clinical trial phase I/II for cancer-associated inflammation in hepatocellular carcinoma. The aim of this study is to find the best dose of the drug without causing side effects. Besides, Phase II of clinical trial ‘MONOCLE’ study for the treatment of chronic myelomonocytic leukemia (CMML) has been initiated and the first patient has been recruited.

BCX-4430 hydrochloride is a salt of an antiviral adenosine analog BCX4430 (Immucillin-A) that acts as a viral RNA-dependent RNA polymerase (RdRp) inhibitor. It was developed as a potential treatment for deadly filovirus infections such as Ebola virus disease and Marburg virus disease but also demonstrated broad-spectrum antiviral effectiveness against a range of other RNA virus families, including, bunyaviruses, arenaviruses, paramyxoviruses, and coronaviruses. Biochemical, reporter-based and primer-extension assays indicate that BCX4430 inhibits viral RNA polymerase function, acting as a non-obligate RNA chain terminator. BCX4430 inhibits infection of distinct filoviruses in human cells. Post-exposure administration of BCX4430 protects rodents against Ebola and Marburg virus disease and cynomolgus macaques from Marburg virus when administered as late as 48 hours after infection. BCX4430 is highly active in a Syrian golden hamster model of yellow fever, even when treatment is initiated at the peak of viral replication. BCX4430 also showed efficacy against Zika virus in a mouse model.

E-3710 (Z-215) is a new proton pump inhibitor (PPI). E-3710 irreversibly inhibited H(+),K(+)-ATPase activity in pig gastric vesicles with an acidic internal environment. E-3710 is a long-acting inhibitor of gastric acid secretion and a promising novel therapy for acid-related diseases, such as gastroesophageal reflux disease. E-3710 is metabolized through oxidation, reduction and conjugation. Unchanged E-3710 was excreted in urine at trace levels but was not detected in faces. The major isozyme contributing to the oxidation of Z-215, including the formation of Z-215 sulphone, was CYP3A4. It is useful for treating gastroesophageal reflux disease in all CYP2C19 genotypes. E-3710 is in phase II clinical trial for the treatment of erosive esophagitis and gastro-esophageal reflux.

Orvepitant is a novel generation brain penetrant, selective and potent, small molecule NK-1 receptor antagonist. Orvepitant’s (GW823296) mode of action and developability characteristics made it a suitable development candidate for the treatment of common anxiety disorders, posttraumatic stress disorder and major depressive disorder. It’s in phase II clinical trials as an effective inhibitor of itch-associated response.

FLEZELASTINE, a phthalazinone derivative, an anti-asthmatic/anti-allergic agent. It exhibits inhibition of histamine release and 5-lipoxygenase, calcium antagonistic properties and antagonism at the histamine H1 receptor. FLEZELASTINE is a racemate consisting of (+)- and (-)-enantiomers. Both enantiomers contribute to the pharmacodynamic efficacy of racemic flezelastine.

FLEROBUTEROL is a beta-adrenoceptor agonist with potential antidepressant activity.

Safotibant (previously known as LF22-0542) was developed as an antagonist at bradykinin B1 receptor for the topical treatment of diabetic macular edema. This drug participated in phase II clinical trials in Australia, in Belgium and in the Czech Republic. However, further, development was discontinued.
