ART0380
Based on 1 Customer Validation
ART0380 is a potent, selective and orally active ATR kinase inhibitor. ART0380 potently inhibits human ATR-ATRIP complex with an IC50 of 51.7 nM. ART0380 binds the ATP pocket of the ATR-ATRIP complex, blocks ATR-dependent Chk1 serine 345 phosphorylation, and induces cell cycle disorder and DNA damage. ART0380 demonstrates potent and selective antitumor activity in preclinical models with varying types of ataxia-telangiectasia mutated (ATM) gene aberrancy. ART0380 can be used for the research of cancer, such as colorectal cancer and prostate cancer.

ART0380 potently inhibits the catalytic activity of the purified human ATR-ATRIP complex with an IC50 of 51.7 nM[1].
ART0380 potently inhibits ATR-dependent pChk1 (Ser345) phosphorylation in HT-29 colorectal adenocarcinoma cells with an EC50 of 0.022 μM[1].
ART0380 exhibits minimal inhibition of mTOR pathway-mediated pRPS6 (Ser235/236) phosphorylation in HT-29 colorectal adenocarcinoma cells, with an EC50 range of 6.0 μM, indicating high selectivity for ATR over mTOR[1].
ART0380 (7 days) potently inhibits proliferation in ATM loss-of-function cancer cell lines (NCI-H23, Granta-519) and replication stress-prone LoVo cells, with weaker activity in normal CCD-18Co colon fibroblasts, showing EC50 values of 0.13, 0.44, 1.0, and 6.4 μM, respectively[1].
ART0380 (0.001 to 1 μM; 7-10 days) exhibits preferential antiproliferative activity in ATM knockout isogenic cell lines (NCI-H460, Calu-6, PC-3) compared to their ATM-proficient parental counterparts, with EC50 values ranging from 0.045-0.213 μmol/L in ATM KO cells and 0.170-1.215 μM in parental cells[1].
ART0380 (0.3-1 μM; 24-48 h) induces cell cycle disorder and increases DNA damage (measured via γH2AX foci) in ATM knockout NCI-H460 cells[1].

ART0380 (100 mg/kg; p.o.; once daily or b.i.d., 3 days on/4 days off.) induces tumor regression in an ATM loss-of-function lung adenocarcinoma PDX model in NSG mice[1].
ART0380 (10-100 mg/kg; p.o.; daily) produces dose-dependent tumor growth inhibition in LoVo colorectal adenocarcinoma xenografts in CD-1 nude mice[1].
ART0380 (100 mg/kg; p.o.; twice daily for 3 days followed by 4 days off) produces significant tumor growth inhibition in ATM-aberrant colorectal cancer PDX models with varying degrees of ATM protein loss, but not in wild-type ATM PDX models, in NSG mice[1].
