Abstract
Protein kinases play a key role in cellular signaling pathways including proliferation, apoptosis, inflammation and immune regulation. Therefore, targeting kinases with small molecules has emerged as a therapeutic potential in cancers and other diseases including inflammatory and autoimmune disorders. The main chemical motifs of the available small molecule kinase inhibitors are heterocyclic, nitrogen-containing and six-membered rings including pyrazine. Several potent and selective pyrazine-based kinase inhibitors have been developed and progressed into clinical trials. The data of clinical application of kinase inhibitors demonstrate good clinical activity with manageable toxicity in several relapse-resistant malignancies and severe to moderate immunological disorders. All pyrazine-based kinase inhibitors are orally active. This paper reviews the most recent kinase literature (2019-2023) related to pyrazine-based small molecule inhibitors. This review includes the FDA (Food and Drug Administration)-approved and patent agents along with their targeted kinase, scaffold, potency, selectivity profile, assignee and biological results in clinical and preclinical studies.

CHK1 inhibitor SRA737 is active in PARP inhibitor resistant and CCNE1 amplified ovarian cancer. iScience 2024; 27:109978. [PMID: 39021796 PMCID: PMC11253285 DOI: 10.1016/j.isci.2024.109978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 04/05/2024] [Accepted: 05/11/2024] [Indexed: 07/20/2024] Open
Abstract
High-grade serous ovarian cancers (HGSOCs) with homologous recombination deficiency (HRD) are initially responsive to poly (ADP-ribose) polymerase inhibitors (PARPi), but resistance ultimately emerges. HGSOC with CCNE1 amplification (CCNE1 amp) are associated with resistance to PARPi and platinum treatments. High replication stress in HRD and CCNE1 amp HGSOC leads to increased reliance on checkpoint kinase 1 (CHK1), a key regulator of cell cycle progression and the replication stress response. Here, we investigated the anti-tumor activity of the potent, highly selective, orally bioavailable CHK1 inhibitor (CHK1i), SRA737, in both acquired PARPi-resistant BRCA1/2 mutant and CCNE1 amp HGSOC models. We demonstrated that SRA737 increased replication stress and induced subsequent cell death in vitro. SRA737 monotherapy in vivo prolonged survival in CCNE1 amp models, suggesting a potential biomarker for CHK1i therapy. Combination SRA737 and PARPi therapy increased tumor regression in both PARPi-resistant and CCNE1 amp patient-derived xenograft models, warranting further study in these HGSOC subgroups.

Oncogene 2024; 43:789-803. [PMID: 38273024 DOI: 10.1038/s41388-024-02939-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 01/03/2024] [Accepted: 01/04/2024] [Indexed: 01/27/2024]
Abstract
WEE1 and CHEK1 (CHK1) kinases are critical regulators of the G2/M cell cycle checkpoint and DNA damage response pathways. The WEE1 inhibitor AZD1775 and the CHK1 inhibitor SRA737 are in clinical trials for various cancers, but have not been thoroughly examined in prostate cancer, particularly castration-resistant (CRPC) and neuroendocrine prostate cancers (NEPC). Our data demonstrated elevated WEE1 and CHK1 expressions in CRPC and NEPC cell lines and patient samples. AZD1775 resulted in rapid and potent cell killing with comparable IC50s across different prostate cancer cell lines, while SRA737 displayed time-dependent progressive cell killing with 10- to 20-fold differences in IC50s. Notably, their combination synergistically reduced the viability of all CRPC cell lines and tumor spheroids in a concentration- and time-dependent manner. Importantly, in a transgenic mouse model of NEPC, both agents alone or in combination suppressed tumor growth, improved overall survival, and reduced the incidence of distant metastases, with SRA737 exhibiting remarkable single agent anticancer activity. Mechanistically, SRA737 synergized with AZD1775 by blocking AZD1775-induced feedback activation of CHK1 in prostate cancer cells, resulting in increased mitotic entry and accumulation of DNA damage. In summary, this preclinical study shows that CHK1 inhibitor SRA737 alone and its combination with AZD1775 offer potential effective treatments for CRPC and NEPC.

Abstract
Replication stress (RS) is a characteristic state of cancer cells as they tend to exchange precision of replication for fast proliferation and increased genomic instability. To overcome the consequences of improper replication control, malignant cells frequently inactivate parts of their DNA damage response (DDR) pathways (the ATM-CHK2-p53 pathway), while relying on other pathways which help to maintain replication fork stability (ATR-CHK1). This creates a dependency on the remaining DDR pathways, vulnerability to further destabilization of replication and synthetic lethality of DDR inhibitors with common oncogenic alterations such as mutations of TP53, RB1, ATM, amplifications of MYC, CCNE1 and others. The response to RS is normally limited by coordination of cell cycle, transcription and replication. Inhibition of WEE1 and PKMYT1 kinases, which prevent unscheduled mitosis entry, leads to fragility of under-replicated sites. Recent evidence also shows that inhibition of Cyclin-dependent kinases (CDKs), such as CDK4/6, CDK2, CDK8/19 and CDK12/13 can contribute to RS through disruption of DNA repair and replication control. Here, we review the main causes of RS in cancers as well as main therapeutic targets-ATR, CHK1, PARP and their inhibitors.

Abstract
BACKGROUND This was a first-in-human Phase 1/2 open-label dose-escalation study of the novel checkpoint kinase 1 (Chk1) inhibitor SRA737. METHODS Patients with advanced solid tumours enrolled in dose-escalation cohorts and received SRA737 monotherapy orally on a continuous daily (QD) dosing schedule in 28-day cycles. Expansion cohorts included up to 20 patients with prospectively selected, pre-specified response predictive biomarkers. RESULTS In total, 107 patients were treated at dose levels from 20-1300 mg. The maximum tolerated dose (MTD) of SRA737 was 1000 mg QD, the recommended Phase 2 dose (RP2D) was 800 mg QD. Common toxicities of diarrhoea, nausea and vomiting were generally mild to moderate. Dose-limiting toxicity at daily doses of 1000 and 1300 mg QD SRA737 included gastrointestinal events, neutropenia and thrombocytopenia. Pharmacokinetic analysis at the 800 mg QD dose showed a mean Cmin of 312 ng/mL (546 nM), exceeding levels required to cause growth delay in xenograft models. No partial or complete responses were seen. CONCLUSIONS SRA737 was well tolerated at doses that achieved preclinically relevant drug concentrations but single agent activity did not warrant further development as monotherapy. Given its mechanism of action resulting in abrogating DNA damage repair, further clinical development of SRA737 should be as combination therapy.

Abstract
In this study, a series of 2-[p-fluorophenyl]-6-substituted-9H-purine analogues were designed and synthesized as CHK1 inhibitors, among which compound b22 was the most potent. b22 exhibited nearly no antiproliferative activity toward HT29 cells and displayed a significant antitumor potentiating effect on HT29 cells when treated in combination with gemcitabine (Gem). A time-dependent assay found that treatment with Gem for 8 h before adding b22 achieved the optimal effect. Furthermore, the immunofluorescence and qPCR results demonstrated that b22 can remarkably reverse the upregulation of PD-L1 induced by Gem, which suggested dual effects of b22 in antitumor potentiation and antitumor immunity.

Abstract
A series of 2-aminothiazole derivatives were designed, synthesized on the basis of bioisosterism strategy and evaluated for their CHK1 inhibitory activity. Most of them exhibited potent CHK1 inhibition, and excellent antiproliferative activity against MV-4-11 and Z-138 cell lines. Systematic structure-activity relationship (SAR) efforts led to the discovery of a promising compound 8 n, which showed potent CHK1 inhibitory activity with IC50 value of 4.25±0.10 nM, excellent antiproliferative activity against MV-4-11 and Z-138 cells with IC50 value of 42.10±5.77 nM and 24.16±6.67 nM, respectively, as well as moderate oral exposure (AUC(0-t) =1076.25 h ⋅ ng/mL) in mice. Additionally, treatment of MV-4-11 cells with compound 8 n for 2 h led to robust inhibition of CHK1 autophosphorylation on serine 296. Furthermore, kinase selectivity assay revealed that 8 n displayed acceptable selectivity toward 15 kinases. These results demonstrated that compound 8 n may be a promising potential anticancer agent for further development.

Abstract
5-(Alkylamino)-6-aryl/alkylpyrazine-2,3-dicarbonitriles were successfully synthesized in good to moderate yields by reacting alkyl isocyanides with aryl/alkyl carbonyl chlorides, followed by the addition of diaminomaleonitrile. The synthesized pyrazines were fully characterized in this investigation, and X-ray crystal structure analysis was performed on some derivatives. The antibacterial and antifungal activities of the newly synthesized pyrazine-2,3-dicarbonitriles were assessed in addition to their UV and fluorescence results. All the compounds showed similar UV-Vis spectral features with absorption peaks (λmax) around 267, 303, and 373 nm.

Abstract
Checkpoint kinase 1 (CHK1) plays an important role in the DNA damage response pathway, being a potential anti-cancer drug target. In this study, we used a strategy for trifluoromethyl substitution to obtain orally bioavailable CHK1 inhibitors to overcome the limitations of lead compound 1, which can only be administered intravenously. After detailed investigation, we identified compound 6c as an oral CHK1 inhibitor, which demonstrated a considerably higher plasma exposure in mice. Compound 6c also showed good kinase selectivity. Moreover, it exhibited a significant antiproliferative effect in MV-4-11 cells singly and a synergistic effect in combination with gemcitabine in HT-29, A549, and RPMI-8226 cells. Additionally, compound 6c could inhibit tumor growth in the MV-4-11 xenograft mouse model. The combination of 6c and gemcitabine exhibited synergistic effect in the HT-29 xenograft mouse model. Thus, compound 6c was found to be a selective and oral potential anticancer CHK1 inhibitor.

Abstract
Checkpoint kinase 1 (CHK1) is a central component in DNA damage response and has emerged as a target for antitumor therapeutics. Herein, we describe the design, synthesis, and biological evaluation of a novel series of potent diaminopyrimidine CHK1 inhibitors. The compounds exhibited moderate to potent CHK1 inhibition and could suppress the proliferation of malignant hematological cell lines. The optimized compound 13 had a CHK1 IC50 value of 7.73±0.74 nM, and MV-4-11 cells were sensitive to it (IC50 =0.035±0.007 μM). Furthermore, compound 13 was metabolically stable in mouse liver microsomes in vitro and displayed moderate oral bioavailability in vivo. Moreover, treatment of MV-4-11 cells with compound 13 for 2 h led to robust inhibition of CHK1 autophosphorylation on serine 296. Based on these biochemical results, we consider compound 13 to be a promising CHK1 inhibitor and potential anticancer therapeutic agent.

Abstract
Checkpoint kinase 1 (CHK1) is an essential kinase with a critical function in cell cycle arrest. Several potent inhibitors targeting CHK1 have been published, but most of them have failed in clinical trials. Acknowledging the emerging consequence of CHK1 inhibitors in medication of cancer, there is a demand for widening the chemical range of CHK1 inhibitors. In this research, we considered a set of in-house plant based semi-synthetic aminoarylbenzosuberene molecules as potential CHK1 inhibitors. Based on a combined computational research that consolidates molecular docking and binding free energy computations we recognized the crucial determinants for their receptor binding. The drug likeness of these molecules were also scrutinized based on their toxicity and bioavailibilty profile. The computational strategy indicates that the Bch10 could be regarded as a potential CHK1 inhibitor in comparison with top five co-crystallize molecules. Bch10 signifies a promising outlet for the development of potent inhibitors for CHK1.

Abstract
Leukemia, a malignant hematological disease, has poor therapeutic outcomes due to chemotherapeutic resistance. Increasing evidence has confirmed that the elevated capacity for DNA damage repair in cancer cells is a major mechanism of acquired chemotherapeutic resistance. Thus, combining chemotherapy with inhibitors of DNA damage repair pathways is potentially an ideal strategy for treating leukemia. Checkpoint kinase 1 (CHK1) is an important component of the DNA damage response (DDR) and is involved in the G2/M DNA damage checkpoint. In the present study, we demonstrated that shRNA-mediated CHK1 silencing suppressed cell proliferation and enhanced the cytotoxic effects of etoposide (VP16) in the chronic myeloid leukemia (CML) cell line K562 through the results of CCK-8, and comet assay. The results demonstrated that shRNA-induced CHK1 silencing can override G2/M arrest and impair homologous recombination (HR) repair by reducing breast cancer susceptibility gene 1 (BRCA1) expression. Cells had no time, and thus limited ability, to repair the damage and were thus more sensitive to chemotherapy after CHK1 downregulation. Second, we tested the therapeutic effect of VP16 combined with CCT245737, an orally bioavailable CHK1 inhibitor, and observed strong synergistic anticancer effects in K562 cells. Moreover, we discovered that CCT245737 significantly prevented the G2/M arrest caused by acute exposure to VP16. Interestingly, CCT245737 inhibited both BRCA1 and Rad51, the most important component of the HR repair pathway. In conclusion, these results revealed that CHK1 is potentially an ideal therapeutic target for the treatment of CML and that CCT245737 should be considered a candidate drug.

Abstract
Rationally designed Mycobacterium tuberculosis (Mtb) inhibitors were synthesized under Buchwald conditions using Pd2 (dba)3 /xantphos and the compounds were investigated for their biological activity against the Mtb standard strain H37Rv and two other clinically isolated multidrug-resistant strains with different drug resistance patterns. Compounds 5e, 6e, 7e, and 8e exhibited excellent antituberculosis activity against H37Rv with a minimum inhibitory concentration (MIC) value of 15 μg/ml. Compounds 5a, 6c, 7b, 8a, 8b, and 8d also displayed their potency with a MIC value in the range of 15-25 μg/ml. In addition to the Mtb studies, compounds 4e, 5e, 7e, and 8e were tested for cytotoxicity on HEK-293 cells and compounds 7e and 8e were identified to have low toxicities of up to 200 and 300 μM, respectively. The synthesized compounds docked with the 2FUM protein of Mtb and the docking studies revealed that compounds 5e, 6e, 7e, and 8e can bind strongly in the active site of the enzyme and showed binding energies of -9.62, -10.7, -11.48, and -12.06 kcal/mol, respectively. Compound 7e forms four hydrogen bonds, whereas compound 8e forms five hydrogen bonds with amino acids, respectively. Based on these results, compounds 7e and 8e might be considered potential lead compounds with good anti-Mtb potency.

Abstract
Checkpoint kinase 1 (CHK1) is a key mediator of the DNA damage response that regulates cell-cycle progression, DNA damage repair, and DNA replication. Small-molecule CHK1 inhibitors sensitize cancer cells to genotoxic agents and have shown single-agent preclinical activity in cancers with high levels of replication stress. However, the underlying genetic determinants of CHK1 inhibitor sensitivity remain unclear. We used the developmental clinical drug SRA737 in an unbiased large-scale siRNA screen to identify novel mediators of CHK1 inhibitor sensitivity and uncover potential combination therapies and biomarkers for patient selection. We identified subunits of the B-family of DNA polymerases (POLA1, POLE, and POLE2) whose silencing sensitized the human A549 non-small cell lung cancer (NSCLC) and SW620 colorectal cancer cell lines to SRA737. B-family polymerases were validated using multiple siRNAs in a panel of NSCLC and colorectal cancer cell lines. Replication stress, DNA damage, and apoptosis were increased in human cancer cells following depletion of the B-family DNA polymerases combined with SRA737 treatment. Moreover, pharmacologic blockade of B-family DNA polymerases using aphidicolin or CD437 combined with CHK1 inhibitors led to synergistic inhibition of cancer cell proliferation. Furthermore, low levels of POLA1, POLE, and POLE2 protein expression in NSCLC and colorectal cancer cells correlated with single-agent CHK1 inhibitor sensitivity and may constitute biomarkers of this phenotype. These findings provide a potential basis for combining CHK1 and B-family polymerase inhibitors in cancer therapy. SIGNIFICANCE: These findings demonstrate how the therapeutic benefit of CHK1 inhibitors may potentially be enhanced and could have implications for patient selection and future development of new combination therapies.

Abstract
All along the drug development process, one of the most frequent adverse side effects, leading to the failure of drugs, is the cardiac arrhythmias. Such failure is mostly related to the capacity of the drug to inhibit the human ether-à-go-go-related gene (hERG) cardiac potassium channel. The early identification of hERG inhibition properties of biological active compounds has focused most of attention over the years. In order to prevent the cardiac side effects, a great number of in silico, in vitro and in vivo assays have been performed. The main goal of these studies is to understand the reasons of these effects, and then to give information or instructions to scientists involved in drug development to avoid the cardiac side effects. To evaluate anticipated cardiovascular effects, early evaluation of hERG toxicity has been strongly recommended for instance by the regulatory agencies such as U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA). Thus, following an initial screening of a collection of compounds to find hits, a great number of pharmacomodulation studies on the novel identified chemical series need to be performed including activity evaluation towards hERG. We provide in this concise review clear guidelines, based on described examples, illustrating successful optimization process to avoid hERG interactions as cases studies and to spur scientists to develop safe drugs.

Abstract
Cyclin-dependent kinase 12 (CDK12) plays a key role in the coordination of transcription with elongation and mRNA processing. CDK12 mutations found in tumors and CDK12 inhibition sensitize cancer cells to DNA-damaging reagents and DNA-repair inhibitors. This suggests that CDK12 inhibitors are potential therapeutics for cancer that may cause synthetic lethality. Here, we report the discovery of 3-benzyl-1-( trans-4-((5-cyanopyridin-2-yl)amino)cyclohexyl)-1-arylurea derivatives as novel and selective CDK12 inhibitors. Structure-activity relationship studies of a HTS hit, structure-based drug design, and conformation-oriented design using the Cambridge Structural Database afforded the optimized compound 2, which exhibited not only potent CDK12 (and CDK13) inhibitory activity and excellent selectivity but also good physicochemical properties. Furthermore, 2 inhibited the phosphorylation of Ser2 in the C-terminal domain of RNA polymerase II and induced growth inhibition in SK-BR-3 cells. Therefore, 2 represents an excellent chemical probe for functional studies of CDK12 and could be a promising lead compound for drug discovery.

Abstract
AIM SRA737 is an orally active small-molecule inhibitor of checkpoint kinase 1 being investigated in an oncology setting. A HPLC-MS/MS method for quantifying plasma concentrations of SRA737 was validated. METHODS & RESULTS Sample preparation involved protein precipitation with acetonitrile following addition of 13C15N-deuterated SRA737 as internal standard. A rapid and selective method was fully validated across a range of 5-20,000 ng/ml, exhibiting good sensitivity, overall precision (expressed as coefficient of variation) ≤8.0% and accuracy 96-102%. Consistently high recovery was observed, with no matrix effect and a lower limit of quantitation of 5 ng/ml. CONCLUSION A novel method for analyzing SRA737 in human plasma has been validated and is now being utilized for quantification of SRA737 in a Phase I trial.
