title: Synthesis of a new allosamidin analog, N,N'-diacetyl-beta-chitobiosyl allosamizoline and its inhibitory activity against some chitinases.
abstract: A new allosamidin analog (2), possessing an N',N'-diacetylchitobiosyl moiety as a constituent, was stereoselectively synthesized through the coupling reaction between the disaccharide thioglycoside derivative (5) and allosamizoline derivative (6). The inhibitory activity of 2 against chitinases derived from an insect, yeast and mold were tested and compared with that of allosamidin (1).
