Biological Activity

[Description]:

3,4-Dihydroxybenzylamine hydrobromide (NSC 263475 hydrobromide) is an improved dopamine analog cytotoxic and inhibits DNA polymerase activity in melanoma cells[2]. 3,4-Dihydroxybenzylamine hydrobromide (NSC 263475 hydrobromide) displays growth inhibitory activity in melanoma cell lines with varying degrees of tyrosinase activity[2].

[In Vitro]

3,4-Dihydroxybenzylamine hydrobromide (1 μM-10 mM; 48 hours) inhibits the growth of all melanoma cell lines with an IC50 of 100 μM, while the SK-MELB cell line exhibits an IC50 of 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. It exhibits IC50values of 10, 25, 67, and 184 μM for S91A,S91B, L1210, and SCC-25 cells, respectively[2]. 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[2]. Cell Viability Assay[1] Cell Line: Human and Murine Melanoma Cell Lines; Non-Melanoma Cell Lines Concentration: 1 μM-10 mM Incubation Time: 48 hours Result: Inhibited melanoma cell Lines growth.

[In Vivo]

3,4-Dihydroxybenzylamine hydrobromide (intraperitoneal injection; 1000 mg/kg; 7 days) has the least toxic effect in non-tumor-bearing B6D2F1 mice,and mice is tolerated at this dose[3]. 3,4-Dihydroxybenzylamine hydrobromide (intraperitoneal injection; 200-800 mg/kg; 21 days) has different effects at different doses, the median life-span are 17, 24.5, 26, 29 and 25 days for 0 mg/kg, 200 mg/kg, 400 mg/kg, 600 mg/kg, and 800 mg/kg, respectively[3]. Animal Model: C57BL/6 mice with B6D2F1 cells[3] Dosage: 200 mg/kg, 400 mg/kg, 600 mg/kg, and 800 mg/kg Administration: Intraperitoneal injection Result: Exhibited increased life-span of 44%,46%, 70% and 50% for 200 mg/kg, 400 mg/kg, 600 mg/kg, and 800 mg/kg, respectively.
