However, bohemamine and deoxybohemamine were shown to be inhibitors of cell adhesion based on LFA-1/ICAM-1 capable of inhibiting adhesion of human pro-myelocytic leukemia HL-60 cells to Chinese hamster ovary cells transfected with human ICAM-1, at IC50 values of 24.3 and 27.2 μg/mL, respectively [164]. Here, ICAM1 is linked to myeloid leukemia.
