The present invention relates to a method for intelligently constructing a list of preferred 5-hydroxytryptamine reuptake inhibitors. The method comprises the following steps: constructing a functional receptor protein of a 5-hydroxytryptamine reuptake inhibitor by a homology modeling method, screening its key protein of interference with human health based on a harmful outcome pathway method, and calculating the binding energy between it and the receptor protein. The method further calculates the comprehensive effect value as the dependent variable by using an information weighting method, screening the main features of the target as the independent variable based on a variance filtering coupled Pearson correlation coefficient method, realizing the establishment of a data set, and coupling a GRU neural network with a 1D-CNN neural network to realize the intelligent construction of a list of preferred 5-hydroxytryptamine reuptake inhibitors. The present invention aims to overcome the inability of current traditional methods to comprehensively evaluate the comprehensive selection effect of the functionality of 5-hydroxytryptamine reuptake inhibitors and interference with human health, and to realize the intelligent construction of a list of preferred 5-hydroxytryptamine reuptake inhibitors with high priority by establishing a deep learning model.

The invention provides compositions and methods for the treatment of depression and other psychiatric disorders. In particular, the invention provides sustained- or controlled-release formulations, particularly extended or slow release formulations, which include at least one monoamine oxidase inhibitor (MAOI), as well as combination therapies that include at least one MAOI and at least one norepinephrine-reuptake-inhibitor (NRI), for use in such compositions and methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The invention discloses an application of Baf-A1 in increasing the yield of mesenchymal stem cell derived extracellular vesicles. The invention reveals that Baf-A1 significantly increases the yield of iPSC-MSC-EVs through a dual mechanism of promoting secretion and inhibiting reuptake for the first time, and does not affect the therapeutic efficacy of Baf-A1. Compared with the untreated iPSC-MSC-EVs, the EVs generated by the iPSC-MSC treated by the Baf-A1 have the same protection effect on ALI and IBD under the same dosage. Therefore, the addition of the Baf-A1 in the iPSC culture process may be a potential strategy for enhancing the yield of the iPSC-MSC-EVs, thereby improving the challenge of low yield of the iPSC-MSC-EVs. In-vivo and in-vitro experiments prove that the yield of EVs can be increased by treating iPSC-MSC by using Baf-A1, and the Baf-A1 can exert the same curative effect as that of an untreated group in treatment of diseases such as acute liver injury and colitis under the condition of ensuring biological safety.

The invention discloses a compound with remarkable noradrenaline (NE) reuptake inhibition activity and application of the compound in preparation of an anti-depression drug. The compound is a compound Oreonudine F. The preparation method of the compound comprises the following steps: extracting an overground part of wild poppy by using 95% ethanol, acidifying an extract, extracting by using petroleum ether, adjusting an acid water layer to be alkaline by using alkali liquor, and extracting by using chloroform. The chloroform extraction part is subjected to silica gel column chromatography, C18 ODS column chromatography, preparative high performance liquid chromatography separation and the like, and the compound Oreonudine F is obtained. In-vitro activity test results show that the compound Oreonudine F significantly inhibits reabsorption of NE (the inhibition rate is 45.6%) in mouse hippocampal neuronal cells HT22, and the inhibition rate of the compound Oreonudine F is superior to that of a positive control drug amitriptyline (the inhibition rate is 35.5%). The invention provides an important candidate compound for developing efficient and novel antidepressant drugs.
