Abstract:
Background: Depression is a common neuropsychiatric disease. As a famous traditional Chinese
medicine with significant anti-depressive and sleep-promoting effects, Ziziphi Spinosae Semen (ZSS) has attracted
the attention of many researchers. Although it is well known that Magnoflorine (MAG) and Spinosin
(SPI) were the main active components isolated from ZSS, there is a lack of research on the combined treatment
of depression with these two ingredients.
Methods: The shaking bottle method was used to simulate the human environment for detecting the changes
in oil-water partition coefficient before and after the drug combination. Cell viability was evaluated by the
MTT assay. To establish a mouse model of depression and insomnia by CUMS method, and then to explore
the effect of combined administration of MAG and SPI on depression in CUMS model by observing behavior
and analyzing pharmacokinetics.
Results: The change in LogP values affected the lipid solubility of MAG and increased the water solubility of
SPI, allowing them to penetrate more easily through the blood-brain barrier into the brain. Compared with the
model group, MAG-SPI with a concentration of 60 μM significantly increased cell survival rate. In both the
TST and FST experiments, the mice showed a decrease in immobilization time. Pharmacokinetic results
showed that the pharmacokinetic parameters, Cmax and AUC of MAG and SPI, were increased in the case of
combination, which resulted in enhancement of their relative bioavailability and improvement of in vivo effects.
Conclusions: The present study demonstrated that a combination of MAG and SPI had a synergistic antidepressant
effect in CUMS mouse model.
