摘要:
Streptococcus mutans (MTCC 497) cell associated alpha-(1-3)-glucans were isolated, characterized and evaluated for their bioactivity profile. Acid hydrolysis of alpha-(1-3)-glucans revealed presence of glucose moieties. Water insoluble alpha-(1-3)-glucans (WIG) were sulfated to convert them into water soluble glucans which were characterized by FT-IR spectral studies. The sulfation of WIG was confirmed by the presence of -O-SO3- and C-O-SO3- characteristic peaks at 1240 and 820 cm(-1). MALDI-TOF analysis of sulfated alpha-(1-3)-glucan revealed 1.2 to 9 kDa fragmentation. Antibacterial profile studies revealed higher growth inhibitory activity against Gram negative than Gram positive bacterial strains by sulfated alpha-(1-3)-glucans. One-fold higher anti-inflammatory activity with IC50 value of 0.11 mg/ml was observed with sulfated alpha-(1-3)-glucans over WIG. Time dependent fibrinolytic potential without requirement of tissue plasminogen activators was observed for sulfated alpha-(1-3)-glucans. This is the first report demonstrating the fibrinolytic and anti-inflammatory property for sulfated alpha-(1-3)-glucans. (C) 2014 Elsevier Ltd. All rights reserved.
