AR and cancer: The total inhibition of AR positive cancer cells caused by Au‐AR pep‐PROTAC is probably because AR is completely degraded at the protein level in a short period of time as some other small molecular AR targeting PROTAC also showed total inhibition of AR positive cancer cells.[46] While these data indicate we need to examine more in‐depth the toxicity of Au‐AR pep‐PROTAC in high concentrations.
