摘要 为研究聚酰胺 胺 (PAMAM)树状大分子对弱酸性亲脂性药物烟酸的增溶作用 ,合成了以乙二胺为核的1 .0~ 6 .0代 (G)PAMAM树状大分子 ,研究了不同 pH值、不同质量浓度的树状大分子对烟酸增溶的影响。结果 :pH值、质量浓度均影响PAMAM树状大分子溶液对烟酸的增溶效果。提示 :增溶的主要原因是由于树状大分子的氨基与烟酸的羧基之间存在静电作用 ,PAMAM树状大分子可作为亲脂性弱酸性药物的增溶剂。 PAMAM dendrimers enhance the solubility of nicotinic acid. PAMAM dendrimers of generation 1 to 6 have been synthesized. The study investigated the effect of pH and concentration of the dendrimers on the solubility enhancement of nicotinic acid. The pH and concentration of the dendrimers influenced the solubility enhancement of nicotinic acid. It suggests that an electrostatic interaction between the carboxyl group of the nicotinic acid and the amine groups of the dendrimers is involved.
