3,4-Dihydroxybenzylamine hydrobromide 抑制黑色素瘤细胞中的 DNA 聚合酶活性，并在具有不同程度酪氨酸酶活性的黑色素瘤细胞系中显示出生长抑制活性。

3,4-Dihydroxybenzylamine hydrobromide inhibits DNA polymerase activity in melanoma cells and displays growth inhibitory activity in melanoma cell lines with varying degrees of tyrosinase activity.

3,4-Dihydroxybenzylamine hydrobromide (1 μM-10 mM; 48 hours) inhibits the growth of all melanoma cell lines (IC50 = 100 μM) and the SK-MELB cell line (IC50 = 122 μM). The IC50 values are 30, 84,90, and 68 μM for Human SK-MEL-30, SK-MEL-2, SK-MEL-3,RPMI-7951 cells, respectively. 3,4-Dihydroxybenzylamine hydrobromide (1 μM-10 mM; 48 hours) cytotoxicity in SK-MEL-2 and SK-MEL-28 cell lines can be enhanced by application of buthionine sulfoximine (BSO). BSO treatment sensitizes marginally pigmented cells to the effects of 3,4-DHBA, and the presence of decreses IC50 values of 3,4-DHBA by 127% in the SK-MEL-28 cell line and by 148% in the SK-MEL-2 cell line. 3,4-Dihydroxybenzylamine hydrobromide exhibits IC50values of 10, 25, 67, and 184 μM for S91A, S91B, L1210, and SCC-25 cells, respectively[1].

3,4-Dihydroxybenzylamine hydrobromide (200, 400, 600 and 800 mg/kg; i.p.; 21 days) has different effects at different doses, the median life-span are 17, 24.5, 26, 29 and 25 days respectively. 3,4-Dihydroxybenzylamine hydrobromide (1000 mg/kg; i.p.; 7 days) has the least toxic effect in non-tumor-bearing B6D2F1 mice,and mice is tolerated at this dose[2].
