AI Technical Summary
Existing antibody-drug conjugates (ADCs) have problems such as low drug loading and easy development of drug resistance when treating cancer. The therapeutic effects of a single bioactive molecule ADC are uneven on different tumor cells, especially the effect is weak on resting cells, and long-term use is prone to drug resistance.
Develop a multi-load ADC molecule containing two or more cytotoxic drugs by linking bioactive molecules such as tubulin inhibitors and topoisomerase inhibitors to the same antibody to form a multi-load ADC molecule and achieve synergistic effects.
It improved the therapeutic effect on tumor cells, enhanced the killing ability of resting cells, reduced the possibility of drug resistance, and improved the therapeutic effect of ADC.
