Abstract
Human intestinal maltase (HMA) is an
a-glucosidase that hydrolyses a-1,4-linkages from the
non-reducing end of malto-oligosaccharides. HMA is
an important target to discover of new drugs for the
treatment of type 2 diabetes. In this study, 308,307
compounds were virtually screened with HMA
using Autodock 3.0.5 in a WISDOM production
environment to discover novel inhibitors. The 42 topscoring
free binding energy compounds, representing
17 groups containing potential hydrogen bonding with
key residues in the active site pocket of HMA, were
tested in vitro for their inhibitory activities against
recombinant HMA expressed from Pichia pastoris.
Compounds 17 and 18 were competitive inhibitors
exclusively forHMAwithout any in vitro inhibition for
human pancreatic a-amylase. The Ki values were
20 lM for both compound 17 and 18.
