  • Publication number: 20020022626
    Abstract: The present invention relates to organic molecules capable of modulating, regulating and/or inhibiting protein kinase signal transduction. Such compounds are useful for the treatment of diseases related to unregulated protein kinase signal transduction, including cell proliferative diseases such as cancer, atherosclerosis, arthritis and restenosis and metabolic diseases such as diabetes. The present invention features indolinone compounds that potently inhibit protein kinases and related products and methods. Inhibitors specific to the FLK protein kinase can be obtained by adding chemical substituents to the 3-[(indole-3-yl)methylene]-2-indolinone, in particular at the 1′ position of the indole ring. Indolinone compounds that specifically inhibit the FLK and platelet derived growth factor protein kinases can harbor a tetrahydroindole or cyclopentano-b-pyrrol moiety.

  • Patent number: 6331555
    Abstract: The present invention concerns compounds which can inhibit platelet derived growth factor receptor (PDGF-R) activity, preferably such compounds also inhibit the activity other members of the PDGF-R super family and are selective for members of the PDGF-R super family. The PDGF-R super family includes PDGF-R and PDGF-R related kinases Flt, and KDR. The featured compounds are active on cell cultures to reduce the activity of the PDGF-R and preferably one or more PDGF-R related kinases. An example of a featured compound, A10 (see FIG. 1a), and its ability to inhibit growth of tumor cells in vivo is described below. Using the present application as guide other compounds able to inhibit PDGF-R and preferably Flt and/or KDR can be obtained. Such compounds are preferably used to treat patients suffering from cell proliferative disorders characterized by inappropriate PDGF-R activity.
