The invention discloses a universal construction method for a protein-targeting chimeric molecule compound. The objective of the invention is to provide a method for adjusting the level of proteins by degrading the proteins through targeted ubiquitination. The construction method mainly comprises the following steps: 1) locating and analyzing a three-dimensional structure of a target protein and predicting active sites; 2) selecting a compound database; 3) virtually screening ligand compounds having high degrees of adaption to the target protein by using a computer; 4) acquiring the screened ligand compounds and screening an optimal ligand compound of the target protein through detection of interaction between micromolecules and the proteins; 5) constructing a protein-targeting chimeric molecule compound composed of the optimal ligand compound of the target protein, ubiquitin ligase E3 identification ligand and Linker connecting the optimal ligand compound of the target protein to the ubiquitin ligase E3 identification ligand by using a combination manner simulated by the computer; and 6) chemically synthesizing the protein-targeting chimeric molecule compound. With the method provided by the invention, the protein-targeting chimeric molecule compound can be rapidly and highly efficiently prepared, and specific degradation of intracellular target proteins is realized.
