Abstract: A method of monotherapy for a subject suffering from abnormal cell growth expressing the epidermal growth factor receptor (EGFR) which comprises orally administering to the subject a therapeutically effective amount of a crystalline polymorph of the hydrochloride salt of N-(3-ethynylphenyl)-6,7-bis(2-methoxyethoxy)-4-quinazolinamine so as to treat the subject.

Abstract: The present invention relates to a stable crystalline form of N-(3-ethynylphenyl)-6,7-bis(2-methoxyethoxy)-4-quinazolinamine hydrochloride designated the B polymorph, its production in essentially pure form, and its use. The invention also relates to the pharmaceutical compositions containing the stable polymorph B form of N-(3-ethynylphenyl)-6,7-bis(2-methoxyethoxy)-4-quinazolinamine as hydrochloride, as well other forms of the compound, and to methods of treating hyperproliferative disorders, such as cancer, by administering the compound.

Abstract: Disclosed herein are novel methods for measuring the activity of one or more cyclin dependent kinases (CDKs) in a sample, based upon the quantitation of CDK-phosphorylated Rb protein. The method for measuring cyclin-dependent kinase (CDK) activity includes the following: i) contacting the sample with an anti-retinoblastoma protein (Rb) capture antibody that specifically recognizes a CDK-phosphorylated Rb and isolating the capture antibody-Rb complex; ii) contacting the capture antibody-Rb complex with an anti-Rb primary antibody and isolating the capture antibody-Rb-primary antibody complex; and iii) measuring the amount of CDK-phosphorylated Rb in the sample by quantitating the primary antibody present in the capture antibody-Rb-primary antibody complex. These methods may be used to assess intracellular CDK activity in cultured cells or in cells taken from an animal. Also disclosed are methods of identifying an agent that modulates the CDK activity.

Abstract: The invention is in the field of cancer treatment. In particular, the present invention provides pharmaceutical compounds capable of interacting with mutant and non-mutant forms of cancer-related regulatory proteins such that the mutant protein regains the capacitv to properly interact with other macromolecules thereby restoring or stabilizing all or a portion of its wild type activity. Regulatory proteins include members of the p53 protein family such as. for example, p53, p63 and p73. The compounds of the invention are useful for cancer treatment. Methods for screening for such pharmacological compounds are also provided.

Abstract: A device for supplying air or medical gases in a conditioned, particularly a moistened and/or heated state to a patient, through an air pipe. The device includes at least one component to be connected to said air pipe, the component being formed by a cylinder-shaped element with an inner tube through which the moistened air flows, which cylinder-shaped element is fitted with self-regulating heating resistors which heat the air flowing through the tube, while the cylinder-shaped tube from one element at least is filled with a material which adsorbs or absorbs the water supplied by a water-supply line from a container, and has a good air-permeability.
