Abstract

NEW MATERIAL:A compound (or its salt) of formula I [R is <=8C organic acid residue; R<1> is H or lower alkyl; R<2>,<3> are H or (OH-substituted) lower alkyl; R<4>,<5> are (esterified or amidated) carboxyl; R<6> is H or aralkyl; D, L are steric configurations of asymmetric C atom]. EXAMPLE:2-(2-Acetamido-2-deoxy-D-galactopyranos-3-0-yl)-D-propionyl-L- alanyl- D-isoglutamine. USE:Prophylactic agent, carcinostatic agent, etc. having strong immunity enhancing activity to cellular immonological reaction (delayed hypersensitivity). PROCESS:The compound I is prepared by condensing a compound II (R<7>,<8> are protecting groups) with a compound III, and eliminating the protecting groups from the product.
