Abstract: 目的:研究胡椒碱、原儿茶醛、白果内脂等6种中药单体对小鼠黑素瘤细胞黑素合成的影响,初步探讨不同的中药单体影响黑素合成的作用机制.方法:培养的黑素瘤CloudmanS91细胞分别以系列浓度的6种中药单体作用72h,测定细胞黑素含量、酪氨酸酶活性并与体外蘑菇酪氨酸酶活性直接测定方法(多巴速率氧化法)测定的结果进行比较.结果:6种单体均能促进CloudmanS91细胞的黑素量生成.胡椒碱、原儿茶醛、白果内脂在最佳促进浓度均较100μmol/L的8-甲氧补骨脂素作用明显(P<0.05),其中0.5mmol/L胡椒碱对黑素含量促进作用最为明显.在实验浓度(0.01~1.00mmol/L)胡椒碱可促进酪氨酸酶活性,体外可直接增加蘑菇酪氨酸酶的活性;原儿茶醛对酪氨酸酶活性无明显影响,体外可直接促进蘑菇酪氨酸酶的活性;白果内脂对酪氨酸酶活性起促进作用,体外对蘑菇酪氨酸酶的活性无影响.结论:中药单体胡椒碱、原儿茶醛、白果内脂可明显促进黑素瘤细胞黑素的合成,原儿茶醛的作用可能不依赖于酪氨酸酶的活化作用.
