LY2584702 is a potent, highly selective adenosine triphosphate (ATP) competitive inhibitor against p70 S6 kinase, a downstream component of the phosphatidylinositol-3-kinase signalling pathway which regulates cell proliferation and survival. LY2584702 underwent clinical trials against solid tumors both as a monotherapy and in combination with erlotinib or everolimus. No responses were observed for treatment as a single agent. LY2584702 was not well tolerated when administered with erlotinib, therefore this combination is not feasible. The combination with everolimus was better tolerated but yielded very limited clinical benefit.

Metindizate was developed as a spasmolytic agent. Information about the current use of this compound is not available.

Pinocembrin (5,7-dihydroxyflavanone) is one of the primary flavonoids isolated from the variety of plants, mainly from Pinus heartwood, Eucalyptus, Populus, Euphorbia, and Sparattosperma leucanthum. Pinocembrin is a major flavonoid molecule incorporated as multifunctional in the pharmaceutical industry. Its vast range of pharmacological activities has been well researched including antimicrobial, anti-inflammatory, antioxidant, and anticancer activities. In addition, pinocembrin can be used as neuroprotective against cerebral ischemic injury with a wide therapeutic time window, which may be attributed to its antiexcitotoxic effects.

MRX-I is a potent oxazolidinone antibiotic against Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, penicillin-intermediate S. pneumoniae, and vancomycin-resistant enterococci. MRX-I demonstrated comparable or slightly higher activity than linezolid and was active against enterococci resistant to both vancomycin and teicoplanin. In addition, MRX-I exhibited bactericidal activities against staphylococci and streptococci but was bacteriostatic against enterococci. MRX-I inhibits formation of functional 70S initiation complex essential for bacterial protein synthesis, leading to the cessation of bacterial growth. Oral MRX-I was associated with a greater bioavailability and exposure when administered with food, and minimal accumulation of MRX-I occurred after multiple-dose administration. Oral MRX-I was well tolerated at single doses of up to 1,200 and 800 mg q12h for up to 28 days; all adverse events were mild to moderate in severity, and there was no drug discontinuation due to adverse events.

Ribuvaptan (BAY 868050) is a vasopressin receptor antagonist that has been developed for treatment of heart failure. No information on current use is available.
