Berzosertib induces apoptosis, inhibnits conlony migration, inhibits cell proliferation, and activates cGAS-STING axes in cancer cells. Berzosertib can be used for the research of cancers, such as head and neck squamous cell carcinoma, and colorectal cancer.

VE-821 is a potent ATP-competitive inhibitor of ATR with K_i/IC₅₀ of 13 nM/26 nM.

ATR-IN-31 is a selective ATR kinase inhibitor with an IC₅₀ of 7 nM. ATR-IN-31 does not significantly inhibit ATM kinase activity. ATR-IN-31 inhibits viability of prostate cancer cells.ATR-IN-31 can be used for the research of prostate cancer.

AZD1390 is a potent, highly selective, orally bioavailable, brain-penetrant ATM inhibitor with an IC₅₀ of 0.78 nM in cell.

Elimusertib (BAY-1895344) is a potent, orally active and selective ATR inhibitor with an IC₅₀ of 7 nM. Elimusertib has anti-tumor activity. Elimusertib can be used for the research of solid tumors and lymphomas.

AZD0156 is a potent, selective and orally active ATM inhibitor with an IC₅₀ of 0.58 nM. AZD0156 inhibits the ATM-mediated signaling, prevents DNA damage checkpoint activation, disrupts DNA damage repair, and induces tumor cell apoptosis.

KU-60019 is an improved ATM kinase-specific inhibitor with IC₅₀ of 6.3 nM.

Camonsertib (RP-3500) is an orally active, selective ATR kinase inhibitor (ATRi) with an IC₅₀ of 1.00 nM in biochemical assays. Camonsertib shows 30-fold selectivity for ATR over mTOR (IC₅₀=120 nM) and >2,000-fold selectivity over ATM, DNA-PK, and PI3Kα kinases. Camonsertib has potent antitumor activity.

Gartisertib (VX-803) is an ATP-competitive, orally active, and selective ATR inhibitor, with a K_i of <150 pM. Gartisertib potently inhibits ATR-driven phosphorylated checkpoint kinase-1 (Chk1) phosphorylation with an IC₅₀ of 8 nM. Antitumor activity.

Mirin is a potent Mre11-Rad50-Nbs1 (MRN) complex inhibitor. Mirin prevents MRN-dependent activation of ATM (IC₅₀=12 μM) without affecting ATM protein kinase activity, and it inhibits Mre11-associated exonuclease activity. Mirin abolishes the G2/M checkpoint and homology-dependent repair in mammalian cells. Mirin prevents ATM activation in response to DNA double-strand breaks (DSBs) and blocks homology-directed repair (HDR) in mammalian cells.

Tuvusertib (M1774; ATR inhibitor 1) is a selective and orally active ATR inhibitor extracted from patent WO2015187451A1, compound I-l, with a K_i value below 1 μΜ.

(E/Z)-Mirin is a mixture of (E)-Mirin and Mirin ((Z)-Mirin) (HY-19959) configurations. Among them, Mirin is an inhibitor of MRN (Mre11-Rad50-Nbs1). Mirin prevents MRN-dependent ATM activation without affecting ATM protein kinase activity.

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.

AZ20 is a potent and selective inhibitor of ATR with an IC₅₀ of 5 nM, and has 8-fold selectivity against mTOR (IC₅₀=38 nM).

Lartesertib (M4076) is an inhibitor of the serine/threonine protein kinase ATM with high potency. Lartesertib can inhibit the growth of multiple hematopoietic cell lines. Additionally, when combined with the ATR inhibitor Tuvusertib (HY-111451), Lartesertib can promote the death of tumor cells, activate the immune signaling pathway, and exhibit anti-tumor activity.

Elimusertib (BAY 1895344) hydrochloride is a potent, orally active and selective ATR inhibitor with an IC₅₀ of 7 nM. Elimusertib hydrochloride has anti-tumor activity. Elimusertib hydrochloride can be used for the research of solid tumors and lymphomas.
