Abstract

"OLIGOSSACARìDEO ALGINATO E SEUS DERIVADOS, SUA PREPARAçãO E SEUS USOS". O presente estudo fornece um oligossacarídeo alginato e seus derivados com grau de polimerização variando de 2 a 22. O oligossacarídeo alginato é composto de ácido manurónico ligado a ácido B-D-manurónico por ligações glicídicas 1,4. Os derivados com terminal reduzido na posição 1 do radical carboxila pode ser preparado por degradação oxidativa. O presente estudo também fornece um processo para preparar o oligossacarídeo alginato e seus derivados, que inclui os procedimentos em que uma solução de alginato é reagida por 2 a 6 h num autoclave a pH 2-6 e temperatura de 100-120?, e o pH é ajustado para 7 após a reação ser interrompida, após o que o oligossacarídeo resultante é oxidado na presença de um oxidante para obter um produto da degradação oxidativa. O oligossacarídeo alginato e seus derivados deste método podem ser usados na manufatura de um medicamente para a profilaxia e tratamento de MA e diabetes.
