This invention discloses the use of solanine A derivatives in the preparation of drugs for the prevention or treatment of obesity, belonging to the field of pharmaceutical technology. The applicant's experimental results show that although the weight-loss activity of these solanine A derivatives is reduced compared to solanine A, they still maintain a significant weight-loss effect and can be used as candidate drugs for treating obesity and weight loss. The solanine A derivatives described in this invention are compounds having the structures shown in Formula 2, 10, or 12: [list of compounds].

The invention provides a lipidosome for treating neuroinflammation as well as a preparation method and application thereof. The lipidosome comprises a carrier formed by assembling phospholipid, cholesterol and an amphiphilic polymer coupled with R peptide, and a medicine loaded on a hydrophobic layer of the carrier, the amino acid sequence of the R peptide comprises ERRPRGRRRGRKC; the medicine comprises any one or a combination of at least two of quercetin, curcumin, rutin, tripterine and drunkenin A. The invention further discloses a preparation method of the medicine. The surface of the carrier is subjected to R peptide functional modification, so that the interaction with epithelial cells of a nasal cavity can be enhanced, and the delivery efficiency of intranasal administration is improved; the endocytosis pathway is regulated and controlled to realize efficient internalization of the medicine, and the medicine is directly delivered to the central nervous system by bypassing the blood brain barrier through olfaction and trigeminal nerve pathways, so that the treatment of neuroinflammation is realized.
