  • Patent number: 6337338
    Abstract: Methods for treating diseases associated with the activity of the insulin growth factor-1 receptor (IGF-1R), such as cancer, are provided. Methods for inhibiting cell growth and proliferation, especially of tumor cells, and promoting apoptosis are also provided. Each of these methods employs the use of a heteroaryl-aryl urea compound as an antagonist for IGF-1R.

  • Patent number: 6329431
    Abstract: Modulation of the activity of the insulin receptor, enhancement of glucose uptake by cells, and other effects significant in the control and management of diabetes are accomplished using compounds of the formula wherein each A is independently a proton-accepting substituent; each R is independently a noninterfering substituent; m is 0 or 1; n is 0, 1, or 2; and each linker is independently —NHCNHNH—, —NHCOO—, OCOO—,—CH═CH—, —CH═N—, —CH2CH2—, —NHCH2—, —OCO— or —COO—. Compounds in the genus of Formula (1) can also be used for structure activity studies to identify features responsible for the relevant activities.

  • Patent number: 6054286
    Abstract: Compounds having immunomodulating activity are identified using a methodology which employs TER14687, TER10311 and/or TER17210 as standards. The effect candidate compounds have on PKC-theta interaction with cognate binding proteins is measured and compared with the standards. The interaction can be measured by a variety of techniques, including assessing translocation of said PKC-theta or fragment. Kits containing the TER14687, TER10311 and/or TER17210 standards are disclosed. TER14687, TER10311 and/or TER17210 are useful in modulating the immune system in a subject by reducing T-cell activity. TER14687, TER10311, TER17210 are used as leads to develop other compounds having immunomodulating activity.

  • Patent number: 5798275
    Abstract: Panels which consist of individual members, said members comprising proteins, wherein at least one of the members of the panel is a protein other than an immunoglobulin (Ig) or fragment thereof and wherein the presence of said non-Ig protein enriches the panel are described herein. These panels can be tested for reactivity with an analyte to create a profile. Such profiles can be used in pattern matching, analysis of samples and other analyses. Illustrated herein using such panels is a method to determine reactivity of a candidate compound with a target "receptor" which method does not require the physical presence of the receptor. By providing a formula for treating data obtained from a reference panel of this type which is predictive of reactivity with the target receptor, the compound to be tested can be physically assessed with respect to the reference panel, the formula applied, and reactivity with the actual target receptor may be predicted.

  • Patent number: 5587293
    Abstract: A method to determine reactivity of a candidate compound with a target receptor which method does not require the physical presence of the receptor is disclosed. By providing a formula for treating data obtained from a reference set of receptors which is predictive of reactivity with the target receptor, the compound to be tested can be physically assessed with respect to the reference receptors, the formula applied, and reactivity with the actual target receptor may be predicted.
