1. Isolation and characterization of new allosamidins
Y Nishimoto, S Sakuda, S Takayama, Y Yamada J Antibiot (Tokyo). 1991 Jul;44(7):716-22. doi: 10.7164/antibiotics.44.716.
Three of new allosamidins, termed glucoallosamidins A (5), B (6) and methyl-N-demethyl-allosamidin (4), were isolated as yeast chitinase inhibitors from the mycelium of Streptomyces sp. SA-684.

The pseudotrisaccharide allosamidin is a potent family 18 chitinase inhibitor with demonstrated biological activity against insects, fungi, and the Plasmodium falciparum life cycle. The synthesis and biological properties of several derivatives have been reported. The structural interactions of allosamidin with several family 18 chitinases have been determined by x-ray crystallography previously. Here, a high resolution structure of chitotriosidase, the human macrophage chitinase, in complex with allosamidin is presented. In addition, complexes of the allosamidin derivatives demethylallosamidin, methylallosamidin, and glucoallosamidin B are described, together with their inhibitory properties. Similar to other chitinases, inhibition of the human chitinase by allosamidin derivatives lacking a methyl group is 10-fold stronger, and smaller effects are observed for the methyl and C3 epimer derivatives. The structures explain the effects on inhibition in terms of altered hydrogen bonding and hydrophobic interactions, together with displaced water molecules. The data reported here represent a first step toward structure-based design of specific allosamidin derivatives.
