Four novel maltopentaosides, 2-chloro-4-nitrophenyl O-(6-O-p-toluenesulfonyl-alpha-D-glucopyranosyl)-(1--&gt;4)-tris[O- alpha-D-glucopyranosyl-(1--&gt;4)]-beta-D-glucopyranoside (4), 2-chloro-4-nitrophenyl O-[6-O-(tert-butyldimethyl)silyl-alpha-D- glucopyranosyl]-(1--&gt;4)-tris[O-alpha-D-glucopyranosyl-(1--&gt;4)]-beta-D- glucopyranoside (5), 2-chloro-4-nitrophenyl O-[6-deoxy-6-(phenyl)sulfonyl-alpha-D- glucopyranosyl]-(1--&gt;4)-tris[O-alpha-D-glucopyranosyl-(1--&gt;4)]-beta-D- glucopyranoside (10), and 2-chloro-4-nitrophenyl O-(6-deoxy-6-phthalimido-alpha-D-glucopyranosyl)- (1--&gt;4)-tris[O-alpha-D-glucopyranosyl-(1--&gt;4)]-beta-D-glucopyranoside (11) were synthesized. Substrates 4, 5, 10, and 11 were hydrolyzed by human pancreatic alpha-amylase (HPA) from 1.1 to 2.9-fold faster than by human salivary alpha-amylase (HSA). Taking advantage of the difference in the hydrolytic rate of 5 (2.9-fold faster), we developed a new method for the differential assay of these two human alpha-amylases.
