Witryna21 gru 2015 · N-substituted chitosan derivatives were synthesized through condensation with a number of selected aryl and heteroaryl aldehydes. The synthesis of the amino-derivatives has been carried out by reductive amination with sodium borohydride as reducing agent. Their structures were characterized by (FT-IR, 1HNMR, and XRD). … Witrynacontaining peptides yielded the intermediate imine which was trapped by reduction with sodium borohydride (Means and Feeney, 1995) (Figure 1A-Src-imine). Incubation of Src with 1 followed by treatment with NaBH4 revealed quantitative adduct formation in five minutes (Figure 1C). The extent of modification was assessed by ultra pressure …
