ISOMETAMIDIUM (as a chloride salt) is widely used in tropical countries as an antiprotozoal agent to control animal trypanosomiasis. It is used principally in cattle but also in sheep, goats, buffalos, donkeys, horses, camels and dogs.

Cetaben has been identified as an anti-atherosclerotic hypolipidaemic substance. Cetaben is a unique, PPARα-independent peroxisome proliferator with hypolipidemic activity that inhibits cholesterol synthesis in the human hepatoma Hep-G2 cells resulting in reversible changes in Golgi morphology. Cetaben represents an exceptional type of peroxisome proliferator, specifically affecting peroxisomes, without having a negative influence on the processes of peroxisome biogenesis. Cetaben raised only the peroxisomal enzymes, acyl-CoA oxidase, glycerone-phosphate acyltransferase, D-amino-acid oxidase, catalase, and urate oxidase. Cetaben sodium has being shown to be an antiatherosclerotic agent.

Oxoprostol was developed as a gastric acid secretion inhibitor. Information about the further development of this drug is not available.

Oxpheneridine is a mu opioid receptor agonist that possesses the spasmolytic activity and acts as a narcotic analgesic. However, this compound was not listed as an illegal drug, because of its poor solubility and low doses didn’t produce any addiction. Information about the current use of this drug is not available.

Loviride (R 89439) is a non-nucleoside inhibitor of reverse transcriptase. It inhibits virion and recombinant reverse transcriptase of HIV-1. It was being studied in the combination therapy of HIV infection with other anti-HIV agents.

Pfizer's CP-547632 is a selective inhibitor of VEGFR-2 tyrosine kinase that was discovered during Pfizer's collaboration with OSI Pharmaceuticals. CP-547632, was identified as a potent inhibitor of the VEGFR-2 and basic fibroblast growth factor (FGF) kinases (IC(50) = 11 and 9 nM, respectively). It is selective relative to epidermal growth factor receptor, platelet-derived growth factor beta, and other related TKs. It also inhibits VEGF-stimulated autophosphorylation of VEGFR-2 in a whole cell assay with an IC(50) value of 6 nM. After oral administration of CP-547632 to mice bearing NIH3T3/H-ras tumors, VEGFR-2 phosphorylation in tumors was inhibited in a dose-dependent fashion (EC(50) = 590 ng/ml). CP-547,632 is a well-tolerated, orally-bioavailable inhibitor presently under clinical investigation for the treatment of human malignancies. CP-547632 is in phase I for the treatment of diabetic retinopathy and age-related macular degeneration.
