Abstract

Natural tetrapeptide Goralatide (AcSDKP) is a selective inhibitor of primitive haematopoietic cell proliferation. It is not stable in vivo and decomposes within 4.5min when applied to live cells. In this work we developed an analog of Goralatide that exhibits cytotoxicity towards human myeloid HL-60, HEL, Nalm-6 leukemia cells, endothelial HUVEC, glioblastoma U251 and transformed kidney 293T cells. The Goralatide analog showed significant stability in organic solution with no tendency to degrade oxidatively.
