Trimethylglycine (TMG) is a cheap, natural, and highly biocompatible compound. Therefore, it has been used in the fields of food and life sciences, but the application of solid TMG is limited to utilisation as an "additive". In the present study, we focussed on the high solubility of TMG in water, derived from the aprotic zwitterionic structure, and proposed TMG as the chemical accounting for a major portion of the aqueous solution (e.g., 50 wt%). High loading of TMG shifted the properties of water and enabled the dissolution of poorly water-soluble cisplatin, an anticancer agent, at high concentration (solubility of cisplatin: 0.15 wt% in water vs 1.7 wt% in TMG aqueous solution). For hepatic arterial infusion, this can reduce the amount of cisplatin administered from 40 to 4 mL. It enables simple injection using a syringe, without the need for catheters and automatic pumps, leading to critical alleviation of the risk to patients. Furthermore, we produced a dry powder from a cisplatin-containing TMG aqueous solution via freeze-drying. Powders can be conveniently stored and transported. Furthermore, cisplatin is often used as a mixture with other drugs, and cisplatin aqueous solutions are not preferred as they dilute the other drugs. [ABSTRACT FROM AUTHOR]
