A stearoyl amino acid salt having a structural formula of the general formula (I), wherein R
1
is H or an aromatic base capable of being substituted by one or more substituents, or a C
1-4
straight chain or an alkyl with a branched chain, the substituent being an alcoholic hydroxyl group or a phenolic hydroxyl group; and R
2
is a C
11-25
saturated or unsaturated aliphatic group. Also provided are methods of preparing the stearoyl amino acid salt, and methods of using the stearoyl amino acid salt. Compared to a prototype drug stearoyl amino acid, the stearoyl amino acid salt described herein has excellent physicochemical properties, good stability, high relative bioavailability, a strong drug effect and a high safety factor. It is thus expected to become a candidate for clinical treatment of neurodegenerative diseases and acute brain injury, and a clinical drug for weight loss, thus having broad application prospects.
一种具有通式(I)的结构式的硬脂酰氨基酸盐,其中R1为H或能够被一个或多个取代基取代的芳香基,或为C1-4直链或带有支链的烷基,取代基为醇羟基或酚羟基;R2为C11-25饱和或不饱和脂肪族基团。还提供了制备硬脂酰氨基酸盐的方法,以及使用硬脂酰氨基酸盐的方法。与原型药物硬脂酰氨基酸相比,本文描述的硬脂酰氨基酸盐具有优异的理化性质,良好的稳定性,高相对生物利用度,强大的药效和高安全系数。因此,预计将成为神经退行性疾病和急性脑损伤的临床治疗候选药物,以及减重的临床药物,具有广泛的应用前景。
