Prexasertib (LY2606368) is an inhibitor of checkpoint kinase 1 (chk1) with potential antineoplastic activity.

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.

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.

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].

BML-277 (C 3742) is a selective checkpoint kinase 2 (Chk2) inhibitor.

SCH900776 (MK-8776) is an agent targeting cell cycle checkpoint kinase 1 (Chk1) with potential radiosensitization and chemosensitization activities.

NSC622608 is a small-molecule ligand for V-domain Ig suppressor of T-cell activation (VISTA) which is an immune checkpoint that affects the ability of T-cells to attack tumors.

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.

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.

BOS-172722 is an inhibitor of the monopolar spindle 1 (MPS1) checkpoint with an IC50 of 2 nM.

GDC0575 monohydrochloride (ARRY575) is a potent and selective inhibitor of cell cycle checkpoint kinase 1 (Chk1) with an IC50 of 1.2 nM. GDC-0575 specifically binds to and inhibits Chk1; this may result in tumor cells bypassing Chk1-dependent cell cycle arrest in the S and G2 M phases, which permits the cells to undergo DNA repair prior to entry into mitosis.

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.

BMS-1001 hydrochloride is an orally active inhibitor of human PD-1 PD-L1 immune checkpoint with low-toxicity in cells.BMS-1001 alleviates the inhibitory effect of the soluble PD-L1 on the T-cell receptor-mediated activation of T-lymphocytes. BMS-1001 is capable of alleviating the PD-1 PD-L1 immune checkpoint-mediated exhaustion of Jurkat T-lymphocytes.

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

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

Motixafortide (BKT140 4-fluorobenzoyl) is an antagonist of CXCR4 (IC50: 1 nM). BMS-1166 hydrochloride is an inhibitor of PD-1 PD-L1 interaction (IC50: 1.4 nM). BMS-1166 rivalries the inhibitory effect of PD-1 PD-L1 immune checkpoint on T cell activation.

Indibulin (D 24851) is a synthetic small molecule with antimitotic and potential antineoplastic activities.Indibulin an orally applicable inhibitor of tubulin assembly, shows potent anticancer activity with a minimal neurotoxicity. Indibulin reduces inter-kinetochoric tension, produces aberrant spindles, activates mitotic checkpoint proteins Mad2 and BubR1, and induces mitotic arrest and apoptosis.

PD 407824 is a chemical BMP sensitiser that promotes increased cellular sensitivity to subthreshold amounts of BMP4.PD 407824 is a potent inhibitor of the checkpoint kinases Chk1 and WEE1 (IC50s: 47 and 97 nM, respectively).

SB-218078 is less potently inhibits Cdc2 (IC50: 250 nM) and PKC (IC50: 1000 nM). SB-218078 is a potent, ATP-competitive, and cell-permeable checkpoint kinase 1 inhibitor that inhibits Chk1 phosphorylation of cdc25C (IC50: 15 nM).
