Prexasertib dimesylate

产品编号 T38620 CAS 1234015-58-7

别名: LY2606368 dimesylate

Prexasertib dimesylate (LY2606368 dimesylate) is a highly selective ATP-competitive second-generation inhibitor of checkpoint kinase 1 (CHK1). With a K i of 0.9 nM and an IC 50 of <1 nM, Prexasertib dimesylate effectively inhibits CHK2 (IC 50 = 8 nM) and RSK1 (IC 50 = 9 nM). Its mechanism of action involves inducing double-stranded DNA breakage and replication catastrophe, ultimately leading to apoptosis. Moreover, Prexasertib dimesylate demonstrates potent anti-tumor activity. 在相同实验条件下，摩尔浓度相同的化合物盐形式与游离态具有相同的生物活性，但盐形式 Prexasertib dihydrochloride 的水溶性和稳定性通常比游离态更好。

产品描述	Prexasertib dimesylate (LY2606368 dimesylate) is a highly selective ATP-competitive second-generation inhibitor of checkpoint kinase 1 (CHK1). With a K i of 0.9 nM and an IC 50 of <1 nM, Prexasertib dimesylate effectively inhibits CHK2 (IC 50 = 8 nM) and RSK1 (IC 50 = 9 nM). Its mechanism of action involves inducing double-stranded DNA breakage and replication catastrophe, ultimately leading to apoptosis. Moreover, Prexasertib dimesylate demonstrates potent anti-tumor activity.
靶点活性	Chk1:<1 nM (IC50), Chk1:0.9 nM (Ki), Chk2:8 nM (IC50)
体外活性	Prexasertib dimesylate (LY2606368 dimesylate) inhibits MELK (IC 50 =38 nM), SIK (IC 50 =42 nM), BRSK2 (IC 50 =48 nM), ARK5 (IC 50 =64 nM). Prexasertib dimesylate requires CDC25A and CDK2 to cause DNA damage[1]. Prexasertib dimesylate (33, 100 nM; for 7 hours) results in DNA damage during S-phase in HeLa cells[1]. Prexasertib dimesylate (8-250 nM; pre-treated for 15 minutes) inhibits CHK1 autophosphorylation (S296) and CHK2 autophosphorylation (S516) in HT-29 cells[1]. Prexasertib dimesylate (4 nM; 24 hours) results in a large shift in cell-cycle populations from G1 and G2-M to S-phase with an accompanied induction of H2AX phosphorylation in U-2 OS cells[1]. Prexasertib dimesylate (33 nM; for 12 hours) causes chromosomal fragmentation in HeLa cells. Prexasertib dimesylate (100 nM; 0.5 to 9 hours) induces replication stress and depletes the pool of available RPA2 for binding to DNA[1]. Cell Cycle Analysis[1]Cell Line: HeLa cells Concentration: 33, 100 nM Incubation Time: For 7 hours Result: Had an IC 50 of 37 nM and resulted in the G2-M population received DNA damage during S-phase but continued to progress through the cell cycle into an early mitosis. Western Blot Analysis[1]Cell Line: HT-29 cells Concentration: 8, 16, 31, 63, 125, 250 nM Incubation Time: Pre-treated for 15 minutes Result: Inhibited CHK1 autophosphorylation (S296) and CHK2 autophosphorylation (S516) (IC 50 of less than 31 nM) in HT-29 cells.
体内活性	Prexasertib dimesylate (LY2606368 dimesylate; 1-10 mg/kg; SC; twice daily for 3 days, rest 4 days; for three cycles) causes growth inhibition in tumor xenografts[1]. Prexasertib dimesylate (15 mg/kg; SC) causes CHK1 inhibition in the blood and the phosphorylation of both H2AX (S139) and RPA2 (S4/S8)[1]. Animal Model: Female CD-1 nu-/nu- mice (26-28 g) with Calu-6 cells[1]Dosage: 1, 3.3, or 10 mg/kg Administration: SC; twice daily for 3 days, rest 4 days; for three cycles Result: Caused statistically significant tumor growth inhibition (up to 72.3%). Animal Model: Female CD-1 nu-/nu- mice (26-28 g) with Calu-6 cells[1]Dosage: 15 mg/kg (Pharmacokinetic Analysis) Administration: SC (200 μL) Result: CHK1 was 7 ng/mL at 12 hours and 3 ng/mL by 24 hours in plasma exposures. Phosphorylation of both H2AX (S139) and RPA2 (S4/S8) was detectable at 4 hours, showing the rapid occurrence of DNA damage.

体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算，可以得到母液配置方法和体内配方的制备方法：比如您的给药剂量是10 mg/kg，每只动物体重20 g，给药体积100 μL，一共给药动物10 只，您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法：2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL)，如您需要配置的浓度超过该产品的溶解度，请先与我们联系。

体内配方的制备方法：取 50 μL DMSO 主液，加入 300 μL PEG300，混匀澄清，再加 50 μL Tween 80，混匀澄清，再加 600 μL ddH2O, 混匀澄清。
