Biological Activity

DN1679 is a potent, orally bioavailable, and highly selective CDK12/13 dual degrader with DC50 of 8.8/9.8 nM, suppresses TNBC growth both in vitro and in vivo.
DN1679 exhibits undesired activity against CDK4, CDK6, and CDK9.
DN1679 significantly inhibited the proliferation of multiple TNBC cell lines, with IC50 values of 31.7 ± 1.1 nM in MDA-MB-157, 49.1 ± 2.5 nM in MDA-MB-231, and 121.4 ± 1.4 nM in MDA-MB-468 cells.
DN1679 effectively suppressed the mRNA levels of key DDR genes, including ATM, ATR, BRCA1, FANCD2, FANCI, and RAD51 in a time-dependent manner.
DN1679 demonstrates robust synergy with the PARP inhibitor olaparib in vivo, leading to significantly enhanced antitumor efficacy.
