生物活性SBE 13 HCl是一種有效的選擇性PLK1抑制劑，IC50為200 pM，選擇性比 Aurora A 激酶, Plk2 和 Plk3高4000多倍。
體外研究SBE 13 decreases cell proliferation in various cancer cell lines, and causes a G2/M arrest followed by apoptosis. In primary cells, SBE 13 does not impair cell cycle and thus proliferation of primary cells. SBE13 in combination with Enzastaurin displays a synergistic reduction of cell proliferation and enhanced apoptosis induction in HCT116(p53-/-) cells.
