The invention belongs to the technical field of medicines, and discloses a ligustrazine derivative modified based on a
monosaccharide structural unit and a preparation method of the ligustrazine derivative. According to the invention, a
monosaccharide structural unit is introduced to carry out
glycosylation modification on ligustrazine molecules, so that the water
solubility, the
biological activity and the
drug effect durability of ligustrazine are remarkably improved, and the pharmacological characteristics of ligustrazine are optimized; the
glycosylation modification not only can improve the
solubility and stability of ligustrazine, but also can improve the
treatment effect of the ligustrazine in specific diseases (such as
alcohol addiction and the like) by increasing the affinity of the ligustrazine to a specific target spot; through the technical scheme, the defects of the existing ligustrazine derivative in the aspects of
bioavailability,
drug effect persistence and the like can be overcome, and the
treatment effect and clinical application value of the ligustrazine derivative are remarkably enhanced; the glycosylated and modified ligustrazine derivative has better targeting property and stability, is suitable for wider
clinical treatment requirements, and particularly shows greater application potential in treatment of diseases such as
alcohol dependence.
