描述 TRAM-34 is a highly selective blocker of intermediate-conductance calcium-activated K+ channel (IKCa1) (Kd=20 nM). TRAM-34 inhibits the cloned and the native IKCa1 channel in human T lymphocytes with a Kd of 20-25 nM and is 200- to 1,500-fold selective over other ion channels. Combinations of TRAM-34 and cyclosporin A are more effective in suppressing lymphocyte mitogenesis than either compound alone[3]. TRAM-34, a specific inhibitor of K(Ca)3.1 channels increased or decreased cell proliferation depending on the concentration. At intermediate concentrations (3-10 microM) TRAM-34 increased cell proliferation, whereas at higher concentrations (20-100 microM) TRAM-34 decreased cell proliferation. TRAM-34, as well as inhibiting K(Ca)3.1, directly interacts with the oestrogen receptor and mimics the effects of 17beta-oestradiol on MCF-7 cell proliferation and gene modulation[4]. TRAM-34 can inhibit the proliferation and invasion of HL-60 cells, and can induce cell apoptosis and G0/G1 arrest. The time and concentration of TRAM-34 have effect on the malignant behavior of HL-60 cells[5].
