Methods and compositions for regulating imidazoline receptors

   
   

The present invention relates to methods and compositions for regulating the activity of imidazoline receptors. In particular, the invention relates to pharmaceutical compositions comprising imidazoleacetic acid-ribotide (IAA-RP), imidazoleacetic acid-riboside (IAA-R) and its related congeners such as pros-linked ribotide and riboside. The invention is based on the discovery that IAA-RP and to a lesser extent IAA-P bind with a high affinity to imidazoline receptors. Antibodies to IAA-RP, IAA-R are additionally provided, as well as screening methods for identification of compounds that either promote or antagonize the activity of IAA-RP, IAA-R and its related congeners. The invention further relates to diagnostic and prognostic methods for detection of abnormalities in levels or activity of IAA-RP and IAA-R. The invention encompasses treatment of disorders related to the imidazoline system, including hypertension, glaucoma, psychiatric (e.g., depression), neurological (e.g., motor disorders, neurodegenerative disorders), diabetes and disorders related to platelet aggregation.

A invenção atual relaciona-se aos métodos e às composições para regular a atividade dos receptors do imidazoline. No detalhe, a invenção relaciona-se às composições pharmaceutical que compreendem o ácido-ribotide imidazoleacetic (IAA-RP), o ácido-riboside imidazoleacetic (IAA-R) e seus congeners relacionados tais como o ribotide e o riboside pros-ligados. A invenção é baseada na descoberta que IAA-RP e a pouco ligamento da extensão IAA-P com uma afinidade elevada aos receptors do imidazoline. Os antibodies a IAA-RP, IAA-R são fornecidos adicionalmente, as.well.as métodos de seleção para a identificação dos compostos que promova ou antagonize a atividade de IAA-RP, de IAA-R e de seus congeners relacionados. A invenção mais adicional relaciona-se aos métodos diagnósticos e prognósticos para a deteção dos abnormalities nos níveis ou na atividade de IAA-RP e de IAA-R. A invenção abrange o tratamento dos disorders relacionados ao sistema do imidazoline, including o hypertension, glaucoma, psychiatric (por exemplo, depression), neurological (por exemplo, disorders do motor, disorders neurodegenerative), diabetes e os disorders relacionaram-se ao aggregation do platelet.
