Zusammenfassung:The present invention provides a special drug conjugate having a hydrophilic acidic stabilization junction. Compared with a conjugate having a lower drug loading, due to the introduction of the acidic stabilization junction, the conjugate in the present invention can also have a higher drug loading (that is, each targeted reagent has more hydrophilic drug junctions), keeps a desired PK property and has a same or better activity in a body.
