A process for the preparation of di- or tri-substituted aluminum salts of carboxyl group-containing, pharmaceutically effective compounds which comprises reacting up to three types of carboxyl group-containing, pharmaceutically effective compounds with an organic aluminum compound expressed by the following formula; ##EQU1## wherein R.sub.1 and R.sub.2, which may be the same or different, stand for an aliphatic, alicyclic or aromatic hydrocarbon residue having up to 10 carbon atoms, and R.sub.3 stands for a hydrocarbon residue as defined with respect to R.sub.1 and R.sub.2, which may be the same as, or different from, R.sub.1 and R.sub.2, or a hydrocarbyloxy group of the formula OR.sub.4 in which R.sub.4 is an aliphatic, alicyclic or aromatic hydrocarbon residue having up to 10 carbon atoms, and a novel di- or tri-substituted aluminum salts of carboxyl group-containing, pharmaceutically effective compounds.
一种制备含羧基、具有药物活性的二或三取代铝盐的工艺,包括将最多三种含羧基、具有药物活性的化合物与下式表示的有机铝化合物反应:##EQU1## 其中R.sub.1和R.sub.2,可能相同或不同,代表具有最多10个碳原子的脂肪族、环烷或芳香烃碳氢基团,而R.sub.3代表与R.sub.1和R.sub.2相同或不同的具有上述定义的碳氢基团,或者是具有最多10个碳原子的脂肪族、环烷或芳香烃碳氢基团的羟基烷氧基团OR.sub.4,从而得到一种新型的含羧基、具有药物活性的二或三取代铝盐。
