Compound for preventing and/or treating neurodegenerative disease

A compound, wherein the compound is a compound of formula I, or a stereoisomer, a racemate, or a pharmaceutically acceptable salt thereof,

• wherein,
• Ring A is selected from the group consisting of
• X1 is selected from the group consisting of O, S, NH, and NR;
• X2 is selected from the group consisting of O, NH, and NR;
• R1 is selected from the group consisting of
• R2 is selected from the group consisting of H, halogen, substituted or unsubstituted C1-C6 alkyl, substituted or unsubstituted C1-C6 alkoxy, and substituted or unsubstituted C3-C6 cycloalkyl;
• R3 and R4 are independently selected from the group consisting of H, D, halogen, substituted or unsubstituted C1-C6 alkyl, substituted or unsubstituted C1-C6 alkoxy, and substituted or unsubstituted C3-C6 cycloalkyl, or R;
• and R4 together with the carbon to which they are attached form a substituted or unsubstituted 3-7 membered cycloalkyl or a substituted or unsubstituted 3-7 membered heterocyclyl containing one or more heteroatoms selected from O, S and N;
• each R5, R6, R7, R5, R9, and R10 is independently selected from the group consisting of H, D, halogen, trifluoromethyl, cyano, hydroxy, amino, substituted or unsubstituted C1-C6 alkyl, substituted or unsubstituted C1-C6 alkoxy, substituted or unsubstituted C1-C6 alkyl-NR16—, substituted or unsubstituted C3-C6 cycloalkyl, substituted or unsubstituted C3-C6 cycloalkoxy, and substituted or unsubstituted C3-C6 cycloalkyl-NR16—;
• each R11, R12, R13, R14, and R15 is independently selected from the group consisting of H, D, halogen, trifluoromethyl, cyano, hydroxy, amino, substituted or unsubstituted C1-C6 alkyl, substituted or unsubstituted C1-C6 alkoxy, substituted or unsubstituted C1-C6 alkyl-NR16, substituted or unsubstituted C3-C6 cycloalkyl, substituted or unsubstituted C3-C6 cycloalkoxy, and substituted or unsubstituted C3-C6 cycloalkyl-NR16—;
• each R17 and R15 is independently selected from the group consisting of H, D, C1-C6 alkyl, C1-C6 alkoxy, C3-C6 cycloalkyl and C3-C6 cycloalkoxy;
• or R17 and R18 together with the carbon to which they are attached form a substituted or unsubstituted 3-7 membered cycloalkyl or a substituted or unsubstituted 3-7 membered heterocyclyl containing one or more heteroatoms selected from O, S and N,
• each R is independently a substituted or unsubstituted C1-C6 alkyl;
• the “substituted” each independently refers to be substituted by one or more substituents selected from the group consisting of D, halogen, trifluoromethyl, cyano, hydroxy, amino, C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkyl-NR16—, C3-C6 cycloalkyl, C3-C6 cycloalkoxy, and C3-C6 cycloalkyl-NR16—;
• each R16 is independently selected from the group consisting of H and C1-C6 alkyl;
• the premise is that when X1 is NH, X2 is O, and R3, R4, R17 and R18 are H, ring A is not
