The preparation of large amounts of tuftsin (50 g) as well as purification by preparative HPLC are presented. Synthesis of several analogues exhibiting significant phagocytosis-stimulating activity of human PMN are described and discussed. On the other hand, the synthesis of a natural human IgG decapeptide fragment 335-344 that could be liberated from the same carrier molecule is presented. This decapeptide fragment, Thr-Ile-Ser-Lys-Ala-Lys-Gly-Gln-Pro-Arg, showed interesting activity in stimulating phagocytosis of human polymorphonuclear leukocytes.
