  • Publication number: 20030087830
    Abstract: Low molecular weight components extracted from shark cartilage and complexes made of copper with amino acid or dipeptide units or analogs thereof are disclosed. Methods are disclosed for the inhibition of angiogenesis (neovascularization) in an animal through the administration of these complexes, which results in treating angiogenesis-dependent diseases.
    Type: Application

  • Patent number: 5750547
    Abstract: The present invention is concerned with novel anticancer agents having potent antineoplastic activity without systemic toxicity and mutagenicity. The novel anticancer agents of the present invention are derivatives of formula I: ##STR1## wherein: A is O or NH; andB is an aryl group selected from the group consisting of phenyl, indane, fluorene, indazole, indole, and pyridine, the aryl group being substituted with at least one substituent selected from the group consisting of hydrogen, C.sub.1-16 alkyl optionally substituted with one or more OH or SH, lower alkoxy, C.sub.3-6 cycloallyl, lower alkylthio, nitro, cyano, lower alkene, lower alkyne, OH, SH, carboxy lower alkyl, carboxy lower alkyl esters, amino, N-lower alkyl, N,N-dilower alkyl and halogen; or a prodrug thereof, with the provisos that when A is NH and B is phenyl:a) B is substituted with at least one substituent other than hydrogen;b) B is not:1) mono-substituted in the 4 position with C.sub.1-2 alkyl, tert-butyl or n-butyl halogen, OH, carboxy C.

  • Patent number: 5653999
    Abstract: Carriers for pharmacologic agents comprise nanoerythrosomes, which are vesicles prepared by the extrusion of red blood cell ghosts, the average diameter of these vesicles is 0.1 .mu.m; the daunorubicin was covalently linked to nanoerythrosomes and the cytotoxicity of daunorubicin conjugated to nanoerythrosomes was assessed on P388D.sub.1 cell line; the results indicated that the cytotoxicity of conjugated daunorubicin was higher than the free daunorubicin, similar results were observed on CDF.sub.1 mice bearing grafted P388D.sub.1 leukemia tumors; daunorubicin-nanoerythrosome conjugates had a higher antineoplastic activity than the free bioactive agent.
