产品描述
Prexasertib(也称为 LY2606368)是一种新型、有效、选择性和 ATP 竞争性 CHK1(检查点激酶 1)蛋白激酶抑制剂,对 CHK1 和 CHK2 的 IC50 值分别<1 nM 和 8 nM。 CHK1 是一种多功能蛋白激酶,对于细胞对 DNA 损伤的反应和活性复制叉数量的控制都是不可或缺的。由于 CHK1 在细胞周期中建立 DNA 损伤检查点方面的作用,CHK1 抑制剂目前正在作为化学增效剂进行研究。 Prexasertib 作为单一药物会导致双链 DNA 断裂,同时消除 DNA 损伤检查点的保护。 Prexasertib 的作用取决于 CHK1 的抑制以及 CDK2 CDC25A 激活的相应增加,这增加了复制叉的数量,同时降低了其稳定性。用 Prexasertib 处理细胞会导致 S 期细胞群中快速出现 TUNEL 和 pH2AX 阳性双链 DNA 断裂。 Prexasertib 在异种移植肿瘤模型中显示出类似的活性,从而导致显着的肿瘤生长抑制。总之,Prexasertib 是一类通过复制灾难来治疗癌症的新型药物的有力代表。

动物实验
Female CD-1 nu-/nu- mice (26-28 g) with Calu-6 cells[1]
1, 3.3, or 10 mg/kg
SC; twice daily for 3 days, rest 4 days; for three cycles
Prexasertib (LY2606368) was prepared as a 10 mmol/L stock in DMSO for in vitro use and in 20% Captisol, pH4, for in vivo use.
In vivo biochemistry and tumor growth inhibition[1]
Female CD-1 nu-/nu- mice (26–28 g) from Charles River Labs were used for this study. Tumor growth was initiated by subcutaneous injection of 1 × 106 Calu-6 cells in a 1:1 mixture of serum-free growth medium and Matrigel in the rear flank of each subject animal. When tumor volumes reached approximately 150 mm3 in size, the animals were randomized by tumor size and body weight, and placed into their respective treatment groups. Vehicle consisting of 20% Captisol pH4 or Prexasertib (LY2606368) was administered by subcutaneous injection in a volume of 200 μL. Four, eight, 12, 24, and 48 hours after drug administration, blood for plasma drug exposure was extracted via cardiac puncture and assayed on a Sciex API 4000 LC/MS-MS system. The xenograft tissue was promptly removed and prepared as previously described. Lysates were analyzed by immunoblot analysis for protein phosphorylation levels. Group means, SEs and P values were calculated using Kronos.[1]
To measure xenograft tumor growth inhibition, tumors were implanted, established, and the animals randomized as above. Eight animals were used in each treatment group. Vehicle alone or Prexasertib (LY2606368) was administered BIDx3, followed by 4 days of rest and repeated for an additional two cycles. Tumor size and body weight were recorded biweekly and compared between vehicle- and drug-treated groups.
药代性质 (ADME/PK)
Forty-five patients were treated; seven experienced dose-limiting toxicities (all hematologic). The maximum-tolerated doses (MTDs) were 40 mg/m(2) (schedule 1) and 105 mg/m(2) (schedule 2). The most common related grade 3 or 4 treatment-emergent adverse events were neutropenia, leukopenia, anemia, thrombocytopenia, and fatigue. Grade 4 neutropenia occurred in 73.3% of patients and was transient (typically < 5 days). Febrile neutropenia incidence was low (7%). The LY2606368 exposure over the first 72 hours (area under the curve from 0 to 72 hours) at the MTD for each schedule coincided with the exposure in mouse xenografts that resulted in maximal tumor responses. Minor intra- and intercycle accumulation of LY2606368 was observed at the MTDs for both schedules. Two patients (4.4%) had a partial response; one had squamous cell carcinoma (SCC) of the anus and one had SCC of the head and neck. Fifteen patients (33.3%) had a best overall response of stable disease (range, 1.2 to 6.7 months), six of whom had SCC. Conclusion: An LY2606368 dose of 105 mg/m(2) once every 14 days is being evaluated as the recommended phase II dose in dose-expansion cohorts for patients with SCC.

其他信息
Prexasertib has been used in trials studying the treatment and basic science of mCRPC, Leukemia, Neoplasm, breast cancer, and Ovarian Cancer, among others.
Prexasertib is an inhibitor of checkpoint kinase 1 (chk1) with potential antineoplastic activity. Upon administration, prexasertib selectively binds to chk1, thereby preventing activity of chk1 and abrogating the repair of damaged DNA. This may lead to an accumulation of damaged DNA and may promote genomic instability and apoptosis. Prexasertib may potentiate the cytotoxicity of DNA-damaging agents and reverse tumor cell resistance to chemotherapeutic agents. Chk1, a serine/threonine kinase, mediates cell cycle checkpoint control and is essential for DNA repair and plays a key role in resistance to chemotherapeutic agents.
CHK1 is a multifunctional protein kinase integral to both the cellular response to DNA damage and control of the number of active replication forks. CHK1 inhibitors are currently under investigation as chemopotentiating agents due to CHK1's role in establishing DNA damage checkpoints in the cell cycle. Here, we describe the characterization of a novel CHK1 inhibitor, LY2606368, which as a single agent causes double-stranded DNA breakage while simultaneously removing the protection of the DNA damage checkpoints. The action of LY2606368 is dependent upon inhibition of CHK1 and the corresponding increase in CDC25A activation of CDK2, which increases the number of replication forks while reducing their stability. Treatment of cells with LY2606368 results in the rapid appearance of TUNEL and pH2AX-positive double-stranded DNA breaks in the S-phase cell population. Loss of the CHK1-dependent DNA damage checkpoints permits cells with damaged DNA to proceed into early mitosis and die. The majority of treated mitotic nuclei consist of extensively fragmented chromosomes. Inhibition of apoptosis by the caspase inhibitor Z-VAD-FMK had no effect on chromosome fragmentation, indicating that LY2606368 causes replication catastrophe. Changes in the ratio of RPA2 to phosphorylated H2AX following LY2606368 treatment further support replication catastrophe as the mechanism of DNA damage. LY2606368 shows similar activity in xenograft tumor models, which results in significant tumor growth inhibition. LY2606368 is a potent representative of a novel class of drugs for the treatment of cancer that acts through replication catastrophe.[2]
CHEK1 encodes the serine/threonine kinase CHK1, a central component of the DNA damage response. CHK1 regulates cell cycle checkpoints following genotoxic stress to prevent the entry of cells with damaged DNA into mitosis and coordinates various aspects of DNA repair. Accordingly, CHK1 has become a target of considerable interest in oncology. CHK1 inhibitors potentiate the efficacy of DNA-damaging chemotherapeutics by abrogating CHK1-mediated cell cycle arrest and preventing repair of damaged DNA. In addition, CHK1 inhibitors interfere with the biological role of CHK1 as a principal regulator of the cell cycle that controls the initiation of DNA replication, stabilizes replication forks, and coordinates mitosis. Since these functions of CHK1 facilitate progression through an unperturbed cell cycle, CHK1 inhibitors are being developed not only as chemopotentiators, but also as single-agent therapies. This review is intended to provide information on the current progress of CHK1 inhibitors in pre-clinical and clinical development and will focus on mechanisms of single-agent activity and potential strategies for patient tailoring and combinations with non-genotoxic agents.[3]
The primary objective was to determine safety, toxicity, and a recommended phase II dose regimen of LY2606368, an inhibitor of checkpoint kinase 1, as monotherapy. Patients and methods: This phase I, nonrandomized, open-label, dose-escalation trial used a 3 + 3 dose-escalation scheme and included patients with advanced solid tumors. Intravenous LY2606368 was dose escalated from 10 to 50 mg/m(2) on schedule 1 (days 1 to 3 every 14 days) or from 40 to 130 mg/m(2) on schedule 2 (day 1 every 14 days). Safety measures and pharmacokinetics were assessed, and pharmacodynamics were measured in blood, hair follicles, and circulating tumor cells. Conclusion: An LY2606368 dose of 105 mg/m(2) once every 14 days is being evaluated as the recommended phase II dose in dose-expansion cohorts for patients with SCC.[1]
