Preparation of biotinylated allosamidins with strong chitinase inhibitory activities
摘要:
NaIO4 oxidation of allosamidin (1), a strong inhibitor of family 18 chitinases, followed by a coupling with Biotin Hydrazide(R) afforded its mono- and dibiotinylated derivatives, 4 and 6. Reduction of 4 by NaBH4 afforded its reduced form 5. Each of these three biotinylated derivatives maintained strong chitinase inhibitory activity. Especially, 6 inhibited a Trichoderma chitinase as strongly as 1. (C) 1998 Elsevier Science Ltd. All rights reserved.
