Antiangiogenic peptides and compositions thereof

   
   

The present invention provides an antiangiogenic polypeptide having the amino acid sequence set forth in SEQ ID NO: 1 or a portion thereof which is effective to inhibit endothelial cell proliferation as determined by the capillary EC proliferation assay. Preferably, the portion has at least 50% inhibition of bFGF-stimulated EC proliferation at 5 Tg/ml, more preferably 75% inhibition, most preferably 95% inhibition.

A invenção atual fornece um polypeptide antiangiogenic que tem a seqüência do amino-ácido determinada no NO. SEQ do ID: 1 ou uma parcela disso que seja eficaz inibir o proliferation endothelial da pilha como determinada pelo assay do proliferation do EC do capilar. Preferivelmente, a parcela tem ao menos a inibição de 50% do proliferation bFGF-estimulado em 5 Tg/ml, inibição do EC de um mais preferivelmente 75%, inibição do o mais preferivelmente 95%.
