Prexasertib dihydrochloride (LY2606368) is an ATP-competitive CHK1 inhibitor (Ki: 0.9 nmol/L). in the cell-free assay, its IC50 values are 8 nM and 9 nM for CHK2 and RSK, respectively.

PF 477736 (PF-736,PF-00477736) is a specifc, effective and ATP-competitive Chk1 inhibitor (Ki: 0.49 nM ) and also inhibits FGFR3, Aurora-A, VEGFR2, Flt3, Fms (CSF1R), Ret and Yes.

Rabusertib (IC-83) is an inhibitor of the cell cycle checkpoint kinase 1 (chk1) with potential chemopotentiating activity. Rabusertib has been used in trials studying the treatment of Cancer, Solid Tumors, Advanced Cancer, Pancreatic Neoplasms, and Non-Small Cell Lung Cancer.

AZD-7762, an effective and specific inhibitor of Chk1(IC50=5 nM), is equally potent against Chk2 and less potent against CAM, Yes, Fyn, Lyn, Hck and Lck.

CHIR-124 is an effective Chk1 inhibitor (IC50: 0.3 nM). It has 2, 000-fold selectivity against Chk2, 500- to 5, 000-fold less activity against Cdc2 and CDK2/4.

CCT245737 is an orally active, selective Chk1 inhibitor with an IC50 of 1.3 nM, and is >1,000-fold selective over CHK2 and CDK1.

GDC-0575 (ARRY-575) is a highly-selective oral small-molecule Chk1 inhibitor(IC50 of 1.2 nM).

Gartisertib (VX-803) is an orally active and selective Rad3-related protein (ATR) inhibitor with antitumor activity, inhibiting the antiproliferative effect induced in ccRCC cells, and inhibiting ATR-driven phosphorylation of checkpoint kinase 1 (Chk1), useful for studying solid tumors.

CHK1-IN-3 is an inhibitor of checkpoint kinase 1 (CHK1; IC50: 0.4 nM).

CHK1-IN-4 hydrochloride is a potent inhibitor of checkpoint kinase 1 (chk1). CHK1-IN-4 hydrochloride potently inhibits chk1 phosphorylation in the tumor cells. CHK1-IN-4 hydrochloride has anti-tumor activity.

GDC-0425 (RG-7602) is an orally administered, selective small molecule inhibitor of checkpoint kinase 1 (ChK1), used in research on various malignancies [1] [2].

Adavosertib (MK-1775) is a small molecule inhibitor of the checkpoint kinase WEE1 (IC50: 5.2 nM). It hinders the G2 DNA damage checkpoint.

Indoximod (NLG-8189) is a methylated tryptophan with immune checkpoint inhibitory activity. Indoximod inhibits the enzyme indoleamine 2, 3-dioxygenase (IDO), which degrades the essential amino acid tryptophan, and may increase or maintain tryptophan levels important to T cell function. Tryptophan depletion is associated with immunosuppression involving T cell arrest and anergy.

TTK/PLK1-IN-1 (Formula I) is an inhibitor of threonine tyrosine kinase (TTK) and polo-like kinase 1 (PLK1), with IC50 values of 7 nM and 72 nM, respectively. It regulates the spindle assembly checkpoint (SAC) and exhibits antitumor activity against triple-negative breast cancer (TNBC).

AHR antagonist 5 is a potent and orally active aryl hydrocarbon receptor (AHR) antagonist(example 39; IC50 < 0.5 μΜ). It significantly inhibits tumor growth combined with checkpoint inhibitor anti-PD-1.

Tuvusertib (M1774) is an orally available ataxia telangiectasia and Rad3-related (ATR) kinase inhibitor (Ki< 1 µΜ) with selective and potentially antitumor activity.Tuvusertib selectively inhibits ATR activity and blocks downstream phosphorylation of serine/threonine protein kinase checkpoint kinase 1 (CHK1), thereby inhibits DNA damage checkpoint activation, disrupting DNA damage repair and inducing apoptosis in tumor cells.

CHK1-IN-2 is an inhibitor of checkpoint kinase 1 (CHK1; IC50: 6 nM).
