N-succinyl chitosan–dialdehyde starch hybrid hydrogels for biomedical applications
A new class of injectable, biocompatible and biodegradable hydrogel is reported. This hydrogel is derived from N-succinyl chitosan (SCS) mixed with water-soluble dialdehyde starch (DAS) without using a conventional chemical crosslinker. The hybrid hydrogel is formed owing to the Schiff's base reaction between amine groups of SCS and dialdehyde groups of DAS to form -CH 000000000000 000000000000...
متن کاملTensile yield properties of starch - filled poly ( ester amide ) materials *
Composite materials were prepared with granular corn starch (CS) or potato starch (PS) and poly(ester amide) resin (PEA), with starch volume fractions (f) up to 0.40. Tensile yield properties were evaluated at strain rates of 0.0017–0.05 s. Yield stress of the CS-PEA materials increased with strain rate and starch content. The strain rate effect became more pronounced as the starch content incr...
متن کاملInstability of succinyl ester linkages in O2'-monosuccinyl cyclic AMP-protein conjugates at neutral pH.
Chromatographic and immunological evidence is presented regarding the hydrolysis of the ester linkage of O2'-monosuccinyl cyclic AMP in neutral solutions. Such hydrolysis occurs whether the nucleotide derivative is present in free form in solution or conjugated through its succinyl carboxyl group via an amide bond to proteins. The latter process apparently occurs when succinyl cyclic AMP is con...
متن کاملEnzymatic radioiodination of succinyl cyclic AMP tyrosine methyl ester by lactoperoxidase and radioimmunoassay for cyclic AMP.
A highly specific and simple radioimmunoassay for cyclic AMP with a sensitivity of 0.04 picomoles/tube has been developed according to the method of Steiner et al., using 125I-succinyl cyclic AMP tyrosine methyl ester as a tracer. The tracer with higher immunoactivities could be simply and constantly prepared by an enzymatic iodination procedure utilizing lactoperoxidase, radioactive iodide and...
متن کاملEvaluation of succinyl neocarzinostatin in vivo.
The toxicity of the bis-succinyl derivative of the protein antibiotic, neocarzinostatin, was compared with the parent compound, neocarzinostatin (NCS), in rats. The derivative was found to be about two to five fold more active than NCS in vivo. The antitumor activity in rats bearing eleven distinct Yoshida hepatoma ascitic cell lines was tested under four possible combinations with regard to si...
