The fatty acid derivatives 3a, b of bacterial cell-wall peptidoglycan peptides related to FK-156 (1) were synthesized and their immunostimulating activities were examined. The new compounds 3a, b showed significant antiinfectious potencies comparable to that of 1 and 3b especially exhibited a potent tumor-suppressive property lacking in 1.
