Synthesis of sulfated chitosan from cuttlebone of Sepia pharaonis (Ehrenberg, 1831) and its capacity to inhibit blood clotting

Abstract

The synthesis of sulfated chitosan from the cuttlebone of Sepia pharaonis (Ehrenberg, 1831) and its potential to inhibit blood clotting were investigated in this study. Cuttlebone-derived chitosan was chemically modified by sulfation to produce sulfated chitosan. This modification was achieved by introducing sulfate groups into the chitosan structure, thereby enhancing its biological properties. The synthesized sulfated chitosan demonstrated a significant capacity to inhibit blood clotting, indicating its potential application as an anticoagulant. Anticoagulant activity was evaluated through in vitro assays, where sulfated chitosan exhibited notable suppression of clot formation. Moreover, this study examined the structural and physicochemical properties (FTIR, XRD, FESEM) of the synthesized sulfated chitosan, providing insights into its potential mechanism of action. These findings suggest that sulfated chitosan derived from Sepia pharaonis cuttlebone holds promise as an effective and biocompatible anticoagulant, thereby presenting a potential avenue for the development of novel therapeutic interventions in the field of cardiovascular medicine and related disciplines.
