Lurosetron (GR 87442) is a serotonin 5HT3 receptor antagonist. It was undergoing clinical evaluation with Glaxo Wellcome in the UK as a potential drug for the treatment of emesis.

Bevirimat (3-O-(3',3'-dimethylsuccinyl) betulinic acid or MPC-4326 or PA-457) potently inhibits replication of both WT and drug-resistant HIV-1 isolates and demonstrate that the compound acts by disrupting a late step in Gag processing involving conversion of the capsid precursor (p25) to mature capsid protein (p24). Bevirimat inhibits replication of both wild-type and drug-resistant HIV-1 isolates in vitro, achieving similar 50% inhibitory concentration values with both categories. Serial drug passage studies have identified six single amino acid substitutions that independently confer bevirimat resistance. These resistance mutations occur at or near the CA-SP1 cleavage site, which is not a known target for resistance to other antiretroviral drugs. Bevirimat has been in phase 2 trial for the treatment of HIV infections. Bevirimat has demonstrated a consistent pharmacokinetic profile in healthy volunteers and HIV-infected patients. The demonstration of an antiviral effect following a single oral dose of bevirimat validates maturation inhibition as a potential target for antiretroviral therapeutics in humans.

Teglarinad (also known as GMX1777) is a prodrug of GMX1778 and is an inhibitor of nicotinamide phosphoribosyl transferase (NAMPT). It is known that NAMPT involves in NAD(+) biosynthesis, which serves as an important substrate for proteins involved in DNA repair. Teglarinad was evaluated in two human head and neck cancer models in combination with radiotherapy. It was shown that the combining GMX1777 with pemetrexed was an effective new therapeutic strategy to treat nonsquamous non-small cell lung carcinoma (NSCLC). In addition, the drug participated in clinical trial phase I/II in combination with temozolomide for the treatment of metastatic melanoma, however, this study was terminated due to financial constraints.

Sarizotan (also known as EMD-128,130), a chromane derivative that was developed as a selective 5-HT1A receptor agonist and D2 receptor antagonist. Experiments on animal models have shown that the drug effectively suppressed levodopa-induced dyskinesia in primate and rodent models of Parkinson's disease, and tardive dyskinesia in a rodent model. Sarizotan participated in phase II/III clinical trials in the treatment of dyskinesia associated with the dopaminergic treatment of Parkinson's disease. However, further development for this disease was discontinued by Merk, because phase III did not confirm earlier Phase II findings. On July 14, 2015, Newron Pharmaceuticals, research, and development company focused on the novel central nervous system (CNS) and pain therapies, announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to sarizotan for treatment of Rett syndrome. Besides, the drug now is an ongoing clinical trial phase II/III to investigate its the tolerability and efficacy in reducing respiratory abnormalities in Rett Syndrome.

Deleobuvir is a drug for the treatment of Hepatitis C, developed by Boehringer Ingelheim. Deleobuvir is a non-nucleoside HCV NS5B polymerase inhibitor that reversibly and noncovalently binds to the thumb pocket 1. It has shown rapid and strong antiviral activity when administered in combination with peginterferon-a2a and ribavirin. In 2014 Boehringer Ingelheim decided to halt further development of deleobuvir because preliminary analysis of phase 3 clinical trials indicated a low efficacy of the drug.

SP-2086 H3PO4 (Retagliptin Phosphate), tetrahydro-imidazo[1,5-a] pyrazine derivative, is a competitive DPP-4 inhibitor innovated in China under development by Jiangsu Hengrui Medicine for the treatment of Type 2 diabetes. In completed phase II trials, retagliptin monotherapy or in combination with metformin significantly decreased the HbA1c level in type 2 diabetic patients. Two phase III trials for retagliptin monotherapy aCnd in combination with metformin, respectively, were ongoing in China. Jiangsu Hengrui Medicine withdrew its application from the Chinese FDA in April 2016 but is expected to refile the application.

Clomegestone (clomagestone) is an investigational steroidal progestogen. Clomegestone exhibits anti-estrogenic activity in estrone stimulated immature mice when administered orally at 100 ug.

Embramine or mebrophenhydramine is an antiallergic agent. Embramine is a histamine H₁-receptor antagonist exerting anticholinergic activity. It may inhibit stimulated platelet functions by inhibiting phospholipase A2. It is prescribed for severe allergic conditions.

Levonadifloxacin is the S-(-) isomer of the benzoquinolizine fluoroquinolone nadifloxacin and is two- to four-fold more active than the racemic mixture. Levonadifloxacin is a potent antibacterial agent against Gram-positive bacteria especially against methicillin resistance Staphylococcus aureus. It also possesses potent bactericidal activity against other resistant variants like quinolone-resistant Staphylococcus aureus, vancomycin and glycopeptide intermediate Staphylococcus aureus and vancomycin resistant Staphylococcus aureus. Intravenous dosage form developed to treat complicated skin and skin structure infections and has recently completed Phase III studies in India and Phase I studies in USA.
