Title: Purine inhibitors of protein kinases, G proteins and polymerases
Usefulness: Purine inhibitors of protein kinases, G proteins and polymerases
Summary: USE (I) are used in the treatment of atherosclerosis, solid tumours and tumour metastasis, benign tumours, e.g. hemangiomas, acoustic neuromas, neurofibromas, trachomas, and pyogenic granulomas, vascular malfunctions, abnormal wound healing, immune and inflammatory disorders, Bechet's disease, gout, gouty or rheumatoid arthritis, psoriasis, diabetic or other retinopathy, macular degeneration, corneal graft rejection, neuroscular glaucoma, Oster-Webber syndrome, restenosis, or fungal, parasitic, and viral infections. Typical tumours inhibited are those of lung, breast, colon, ovary, prostate, and hepatic cells. They are also used in the treatment of neurodegenerative diseases such as Alzheimer's, Alper's, and Leigh's diseases, AIDS-related dementia, Lewy body disease, epilepsy, multiple system atrophy, Guillain-Barre syndrome, lipofuchsinosis, Down's syndrome, and vertigo. (I) are used to treat laboratory and farm animals and domestic pets, and even inhibition of undesirable growth of plants. (I) can also be used as molecular tools and probes in research. They can be used alone, or in combination therapy with other, known, drugs, particularly chemotherapeutic and antineoplastic compounds.
Novelty: New 6-Arylamino-2-hydroxyalkylaminopurine derivatives of olomoucine are cellular kinase, G protein, and polymerase inhibitors, for treating e.g. cancer, arthritis and psoriasis

Abstract:
Selective protein kinase inhibitors were developed on the basis of the unexpected binding mode of 2,6,9-trisubstituted purines to the adenosine triphosphate-binding site of the human cyclin-dependent kinase 2 (CDK2). By iterating chemical library synthesis and biological screening, potent inhibitors of the human CDK2-cyclin A kinase complex and of Saccharomyces cerevisiae Cdc28p were identified.

The invention relates to purine analogs that inhibit, inter alia, protein kinases, G-proteins and polymerases. In addition, the present invention relates to methods of using such purine analogs to inhibit protein kinases, G-proteins, polymerases and other cellular processes and to treat cellular proliferative diseases. The generation of selective inhibitors for specific protein kinases may provide new tools for analyzing signal transduction pathways and possibly new therapeutic agents.
Applications:
? Inhibitors for protein kinases Analysis of signal transduction pathways Therapeutics Licenses are available in fields EXCEPT for neurodegenerative disease
Features/Benefits:
? The most potent inhibitor, purvalanol B(IC50 = 6 nM), binds with a 30-fold greater affinity than the known CDK2 inhibitor, flavopiridol.
