PROTAC ATR degrader-1
Based on 1 Customer Validation
PROTAC ATR degrader-1 is a ATR PROTAC degrader. PROTAC ATR degrader-1 promotes ubiquitination and degradation of ATR. PROTAC ATR degrader-1 facilitates the progression of cells through the G2/M phase, thereby impairing DNA repair and inducing Apoptosis. PROTAC ATR degrader-1 exerts anticancer effects against colorectal cancer either alone or in combination with Cisplatin (HY-17394). PROTAC ATR degrader-1 can be used in research related to colorectal cancer.

PROTAC ATR degrader-1 (Compound ZS-7) (72 h) potently inhibits the proliferation of ATM-deficient LoVo cells with an IC50 of 0.47 μM and ATM-proficient HCT116 cells with an IC50 of 5.10 μM in vitro[1].
PROTAC ATR degrader-1 (0.16-10 μM; 72 h) induces concentration-dependent degradation of ATR in ATM-deficient LoVo cells with a DC50 of 0.53 μM and a maximum degradation rate of 84.3% after 72 h of treatment[1].
PROTAC ATR degrader-1 (0.16-10 μM; 72 h) potently inhibits ATR pathway signal transduction in ATM-deficient LoVo cells by reducing total ATR protein, phosphorylated ATRThr1989, and phosphorylated CHK1Ser345 levels in a concentration-dependent manner after 72 h of treatment, without degrading CHK1 protein[1].
PROTAC ATR degrader-1 (0.5-1 μM; 72 h) induces significant DNA damage in ATM-deficient LoVo cells, as evidenced by increased γH2AX foci formation after 72 h of treatment at 0.5 μM and 1 μM[1].
PROTAC ATR degrader-1 (0.5-1 μM; 48 h) induces apoptosis in ATM-deficient LoVo cells, with apoptotic rates of 23.91% and 45.62% after 48 h of treatment at 0.5 μM and 1 μM, respectively[1].
PROTAC ATR degrader-1 (0.5-1 μM; 72 h) alleviates G2/M arrest and promotes cell cycle progression through S phase in ATM-deficient LoVo cells in a concentration-dependent manner after 72 h of treatment[1].
