Abstract:
The cell differentiation-inducing effect of 2-N,N-diethylaminocarbonyloxymethyl-1-diphenylmethyl-4-(3,4,5-trimethoxybenzoyl) piperazine, hydrochloride (PMS-1077) was determined in human leukaemic HL-60 cells with profiling of cell proliferation, analysis of cell cycling, characterization of expression of various CD molecules and determination of phagocytotic activity of differentiated HL-60 cells. After treatment with PMS-1077, HL-60 cells exhibited a decreased cell viability during which cell cycle was arrested in G₀-/G₁-phase. Flow cytometric analysis showed CD11b and CD14 were up-regulated, whereas CD15 was unaffected. Together with the finding that PMS-1077-treated HL-60 cells exhibited activities of differentiation by examining their ability of phagocytosing latex beads, an antiproliferative effect and a differentiation-inducing role were determined for PMS-1077 in HL-60 cells.
