    摘要: Disclosed are water-soluble salts of the known coordination compounds 2-hydroxymalonato diammine platinum (II), 2-hydroxymalonato (1,2-diaminocyclohexane)platinum (II) and 2-hydroxymalonato (1,1-diaminomethylcyclohexane)platinum (II). The novel sodium and ammonium salts of the present invention possess high water-solubility, thus allowing intravenous dosage forms to be prepared.

    摘要: The invention concerns a levulinic acid addition salt of the antihypertensive agent 4-amino-6,7-dimethoxy-2-[4-(5-methylthio-1,3,4-oxadiazole-2-carbonyl]piperazin-1-yl)quinazoline in which the base to acid mole ratio is 1 to from 1.25-1.35. The salt is characterized in having improved water solubility and stability compared to the levulinate salt having a 1:1 ratio of base to acid.
