DN1679

DN1679 is a potent, selective, and orally active CRBN-dependent dual degrader of CDK12/13 PROTAC. It exhibits DC50 values for CDK12/13 at 8.8/9.8 nM in MDA-MB-231 cells, 5.1/6.4 nM in MDA-MB-157 cells, and 17.2/15.8 nM in MDA-MB-468 cells. DN1679 downregulates mRNA levels of DNA damage response genes such as ATM, ATR, BRCA1, and RAD51. When used in combination with Olaparib, DN1679 shows a significant synergistic anti-tumor effect. It is applicable in research on triple-negative breast cancer.
