Abstract: The present invention relates to pyrimido [5,4-d] pyrimidine compounds of Formula II or a pharmaceutically acceptable salt thereof, wherein Q is and X, E1, E2, E3, R6 and p are as defined herein. The compounds of this invention are irreversible inhibitors of tyrosine kinases and are useful in the treatment of cancer, atherosclerosis, restenosis, endometriosis and psoriasis.

Abstract: Administration of an irreversible tyrosine kinase inhibitor such as CI-1033 in combination with one or more other antineoplastic agent(s), or ionizing radiation is synergistic for treating cancer.

Abstract: The present invention provides compounds that are irreversible inhibitors of tyrosine kinases. Also provided is a method of treating cancer, restenosis, atherosclerosis, endometriosis, and psoriasis and a pharmaceutical composition that comprises a compound that is an irreversible inhibitor of tyrosine kinases.

Abstract: This invention provides pyridopyrimidines and 4-aminopyrimidines that are useful for treating cell proliferative disorders, such as cancer and restenosis. We have now discovered a group of 7,8-dihydro-2-(amino and thio)pyrido[2,3-d]pyrimidines and 2,4-diaminopyrimidines that are potent inhibitors of cyclin-dependent kinases (cdks) and growth factor-mediated kinases. The compounds are readily synthesized and can be administered by a variety of routes, including orally, and have sufficient bioavailability. This invention provides compounds of Formula I: and Formula II: where W is NH, S, SO, or SO2, R1 includes phenyl and substituted phenyl, R2 includes alkyl and cycloalkyl, R3 includes alkyl and hydrogen, R8 and R9 include hydrogen and alkyl, and Z is carboxy. This invention also provides pharmaceutical formulations comprising a compound of Formula I or II together with a pharmaceutically acceptable carrier, diluent, or excipient therefor.

Also provided is a method of treating cancer, restenosis, atherosclerosis, endometriosis, and psoriasis and a pharmaceutical composition that comprises a compound that is an irreversible inhibitor of tyrosine kinases.

Abstract: Methods of treating proliferative diseases or viral, inflammatory, allergic and cardiovascular diseases, and restenosis are disclosed. The present invention demonstrates the use of N,N'-piperazinylbis-?2-amino-1-imidazolin-2-yl)-2-imidazolines!, 2-amino-1-(2-imidazolin-2-yl)-2-imidazolines, and N,N'-alkylene-bis?2-amino-1-(2-imidazolin-2-yl)-2-imidazolines!, their derivatives, and salts thereof, to antagonize the association of a protein tyrosine kinase with a substrate regulatory protein. The present invention also demonstrates the use of pharmaceutical compositions employing N,N'-piperazinylbis?2-amino-1-imidazolin-2-yl)-2-imidazolines!, 2-amino-1-(2-imidazolin-2-yl)-2-imidazolines, and N,N'-alkylenebis-?2-amino-1-(2-imidazolin-2-yl)-2-imidazolines!, their derivatives, and salts thereof, to antagonize the association of a protein tyrosine kinase with substrate regulatory protein. The present invention also relates to novel N,N'-piperazinylbis?2-amino-1-imidazolin-2-yl)-2-imidazolines!.
