Butoprozine increased the action potential duration like amiodarone, depressed the plateau phase like verapamil and decreased the amplitude and the maximum rate of depolarization. Butoprozine injected intravenously depressed sino-atrial node function, lengthened A-V nodal conduction time and the A-V nodal refractory period, and prolonged the atrial refractory period. Thus butoprozine acted preferentially on parts of the myocardial tissue where the slow inward current seems to be particularly involved. In this respect, butoprozine was more active than amiodarone, but in contrast to this drug, butoprozine did neither prolong the ventricular monophasic action potential duration nor the ventricular refractory period.

Betamicin is an aminoglycoside antibiotic

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.

Napsagatran [RO 466240], a reversible and highly selective thrombin inhibitor, was in development with Roche for use in myocardial infarction and thrombosis. Napsagatran efficiently inhibits and delays thrombin generation in human coagulating plasma. This reduced thrombin generation might be caused by inhibition of thrombin-mediated feedback reactions during blood coagulation. Ro 46-6240 inhibited clot-bound thrombin three times more potently than fluid-phase thrombin (IC50 19 vs 56 ng/ml) while hirudin was two times (IC50 8 vs 3 ng/ml) and heparin six times (IC50 1,205 vs 200 ng/ml) less active against clot-bound thrombin compared with fluid-phase thrombin.

Folitixorin, a thymidylate synthase inhibitor is a substrate used by the enzyme methylenetetrahydrofolate reductase (MTHFR) to generate 5-methyltetrahydrofolate. Folitixorin was studied in clinical trials for the treatment of breast cancer, metastatic colorectal cancer and for the treatment of advanced pancreatic cancer. Folitixorin had been granted orphan drug status for the treatment of pancreatic cancer in both the U.S. and EU. However, further development of this drug was discontinued.

Ezatiostat (TLK199) [γ-glutamyl-S-(benzyl)cysteinyl-R-phenyl glycine diethyl ester] is an inhibitor of Glutathione S-transferase P1–1 (GSTπ). The drug is a peptidomimetic of GSH (glutathione), esterified to enhance cellular uptake and designed to bind to the “G-site” of GSTP1–1. Independent of catalysis inhibition, TLK199 also disrupts the protein:protein interaction site(s) between GSTP1–1 and JNK1. Telik Inc was developing TLK-199 for the potential prevention of myelosuppression in blood diseases, namely myelodysplastic syndrome.

Oglufanide, an angiogenesis inhibitor, an immunomodulator, that originally was developed and registered in Russia under the brand name timogen. Oglufanide inhibits vascular endothelial growth factor (VEGF), which may inhibit angiogenesis. This agent has also been reported to stimulate the immune response to hepatitis C virus and intracellular bacterial infections. Oglufanide was studied in the USA for the treatment of cancer, and in September 2001, it was granted Orphan Drug designation for the treatment of ovarian cancer. In addition, in Australia this drug was involved in phase II clinical trial for the treatment of hepatitis C. Oglufanide is also participated in phase III trials for patients with Kaposi's sarcoma, however, this study was discontinued.

1,​2-​Dioleoyl-​sn-​glycero-​3-​phospho-​L-​serine Sodium Salt is a lipid being studied in the assembly and long-term stability of solid supported lipid bilayers from artificial and natural lipid mixtures.
