Abstract: The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain pyrazolo[1,5-a]pyrimidine-5,7-diamine compounds (referred to herein as “PPDA compounds”) that, inter alia, inhibit (e.g., selectively inhibit) CDK (e.g., CDK1, CDK2, CDK4, CDK5, CDK6, CDK7, CDK8, CDK9, CDK10, CDK11, CDK12, CDK13, etc.).

Abstract: A method for suppressing the expression of a selected gene in a cell, the method comprising introducing into the cell a molecule comprising (1) a nucleic acid binding portion which binds to a site or associated with the selected gene which site is present in a genome and (2) an expression repressor portion, wherein the nucleic acid binding portion comprises an oligonucleotide or oligonucleotide mimic or analogue, and wherein the repressor portion comprises a polypeptide or peptidomimetic. Molecules for use in the methods of the invention are provided. The repressor may be a portion of a histone deacetylase or DNA methylase or polypeptide capable of recruiting a histone deacetylase or DNA methylase.

Abstract: This invention provides a class of compounds which are useful for specifically inhibiting cyclin-dependent kinases. This class of compounds finds use in treating diseases resulting from inappropriate activity of cyclin-dependent kinases, including cancer, viral infections (e.g., HIV) neurodegenerative disorders (e.g. Alzheimer's disease), and cardiovascular disorders (e.g. atherosclerosis). Moreover, certain members of this class are particularly useful for inhibiting cyclin-dependent kinase 7 and are especially useful for the treatment of breast cancer.

Abstract: The current invention provides a method for aiding in the assessment of prostate cancer (including metastatic prostate cancer) and/or benign prostate hyperplasia in a patient, wherein the method comprises the step of determining the level of Glycine N-methyltransferase (GNMT) nucleic acid and/or protein in a sample from the patient. The invention also provides compounds that target Glycine N-methyltransferase (GNMT) protein and/or nucleic acid for use in treating prostate cancer. Also provided are screening methods for selecting a compound considered to be useful in treating prostate cancer, comprising the steps of determining the ability of a test compound to reduce GNMT activity and selecting a compound that reduces GNMT activity. The invention also provides methods for aiding in the diagnosis of prostate cancer in a patient comprising obtaining a sample from the patient and assessing said sample for a marker of GNMT activity.
