Objective

To study the in vitro and in vivo pharmacodynamics of dirozalkib.

Methods

Prepare dirozalkib solutions with concentrations ranging from 3.81×10-3 to 1 000.00 nmol·L-1. The activities of dirozalkib against kinases anaplastic lymphoma kinase (ALK), ALK-L1196M, and ALK-G1202R were evaluated using the Mobility Shift Assay and Radioisotope Filter Binding methods. The inhibitory effect of dirozalkib on cell proliferation was evaluated using the CellTiter-Glo assay in multiple Ba/F3 cell lines transfected with EML4-ALK fusion genes and drug-resistant mutants, at concentrations ranging from 1.53×10-2 to 1 000.00 nmol·L-1. Ba/F3-EML4-ALK-L1196M (crizotinib-resistant) cells were subcutaneously inoculated in NOD SCID mice. The tumor-bearing mice were randomly divided into blank group (solvent control), experimental group (50 mg·kg-1 dirozalkib), control group (50 mg·kg-1 crizotinib), each group consisted of 9 mice. The mice were gavage once a day, continuous administration over a 14-day period. BALB/c nude mice were used to establish a human lung cancer tumor tissue-derived LU-01-0319R (crizotinib-resistant) patient-derived tumor xenograft (PDX) model. The tumor-bearing mice were randomly divided into blank group (solvent control), experimental group (24 mg·kg-1 dirozalkib), control group (24 mg·kg-1 crizotinib), each group consisted of 9 mice. The mice were gavage once a day, continuous administration over a 21-day period. Human lung cancer H228-luc cells were intracranially inoculated in BALB/c nude mice. The tumor-bearing mice were randomly divided into blank group (solvent control), experimental group (100 mg·kg-1 dirozalkib), control group (100 mg·kg-1 crizotinib), each group consisted of 9 mice. The mice were gavage once a day, continuous administration over a 14-day period. Assessed the anti-tumor efficacy of dirozalkib.

Results

Dirozalkib significantly inhibited the kinase activities of ALK, ALK-L1196M, and ALK-G1202R [50% inhibiting concentration (IC50) <1.0 nmol·L-1]. In cells, dirozalkib exhibited significant proliferation inhibitory activity against NCI-H3122 cells harboring EML4-ALK fusion (IC50 = 3.00 nmol·L-1). Additionally, it demonstrated potent inhibitory activity against multiple cell lines with EML4-ALK fusion and drug-resistant mutants of crizotinib and second-generation ALK inhibitors (IC50: 1.92-62.85 nmol·L-1). In the crizotinib-resistant Ba/F3-EML4-ALK-L1196M xenograft model, dirozalkib at a dose of 50 mg·kg-1 had a significant anti-tumor effect, with a relative tumor proliferation rate of 6.14%. In the LU-01-0319R human lung cancer xenograft model (crizotinib-resistant PDX model), the 24 mg·kg-1 dirozalkib also had a significant tumor inhibitory effect, with a relative tumor proliferation rate of 13.19%. For the H228-luc human lung cancer intracranial inoculation model, dirozalkib at 100 mg·kg-1 could significantly inhibit tumor growth [BLI value was (569.34±153.65) × 105 photons·s-1]and could significantly prolong the survival time of the animals.

Conclusion

Dirozalkib effectively inhibits ALK and various resistance mutations associated with first- and second-generation ALK-TKIs, and shows significant antitumor activity in multiple tumor models, including intracranial implantation models.

目的

研究地罗阿克的体内外药效。

方法

配制3.81×10-3~1 000.00 nmol·L-1地罗阿克溶液,用Mobility Shift Assay和Radioisotope Filter Binding方法评价地罗阿克对间变淋巴瘤激酶(ALK)、ALK-L1196M、ALK-G1202R的活性。用CellTiter-Glo试剂盒在多株转染EML4-ALK融合基因及耐药突变型的Ba/F3细胞上考察1.53×10-2~1 000.00 nmol·L-1地罗阿克对细胞的增殖抑制作用。在NOD SCID小鼠皮下接种Ba/F3-EML4-ALK-L1196M(克唑替尼耐药)细胞,随机分为空白组(溶剂对照)、实验组(50 mg·kg-1地罗阿克)和对照组(50 mg·kg-1克唑替尼),每组9只,每天灌胃给药1次,连续给药14 d。用BALB/c裸鼠建立人肺癌肿瘤组织来源的LU-01-0319R(克唑替尼耐药)病人来源肿瘤异种移植(PDX)模型,随机分为空白组(溶剂对照)、实验组(24 mg·kg-1地罗阿克)和对照组(24 mg·kg-1克唑替尼),每组9只,每天灌胃给药1次,连续给药21 d。在BALB/c裸鼠颅内接种人源肺癌H228-luc细胞,随机分为空白组(溶剂对照)、实验组(100 mg·kg-1地罗阿克)和对照组(100 mg·kg-1克唑替尼),每组9只,每天灌胃给药1次,连续给药14 d。评价地罗阿克的抗肿瘤作用。

结果

地罗阿克对ALK、ALK-L1196M、ALK-G1202R激酶活性均有明显抑制作用[半数抑制浓度(IC50)均小于1.0 nmol·L-1]。地罗阿克对EML4-ALK融合的细胞株(NCI-H3122)具有显著的增殖抑制活性(IC50=3.00 nmol·L-1),对于具有EML4-ALK融合的细胞株以及克唑替尼和2代酪氨酸激酶抑制药(ALK-TKI)耐药突变株均具有较强的抑制活性(IC50:1.92~62.85 nmol·L-1)。在克唑替尼耐药的Ba/F3-EML4-ALK-L1196M异种移植模型上,50 mg·kg-1地罗阿克有显著的抗肿瘤作用,相对肿瘤增殖率为6.14%;在LU-01-0319R人源肺癌异种移植模型(克唑替尼耐药PDX模型)上,24 mg·kg-1地罗阿克有显著的抑瘤作用,相对肿瘤增殖率为13.19%;对于H228-luc人源肺癌颅内接种模型,100 mg·kg-1地罗阿克能够显著抑制肿瘤生长,肿瘤部位光学信号强度(BLI)值为(569.34±153.65)× 105 photons·s-1,且能显著延长动物的存活时间。

结论

地罗阿克能够很好地抑制ALK及多种一代、二代ALK-TKI的耐药突变,在多种肿瘤模型(包括颅内接种模型)中均表现出了显著的抗肿瘤作用。

目的

研究地罗阿克的体内外药效。

方法

配制3.81×10-3~1 000.00 nmol·L-1地罗阿克溶液,用Mobility Shift Assay和Radioisotope Filter Binding方法评价地罗阿克对间变淋巴瘤激酶(ALK)、ALK-L1196M、ALK-G1202R的活性。用CellTiter-Glo试剂盒在多株转染EML4-ALK融合基因及耐药突变型的Ba/F3细胞上考察1.53×10-2~1 000.00 nmol·L-1地罗阿克对细胞的增殖抑制作用。在NOD SCID小鼠皮下接种Ba/F3-EML4-ALK-L1196M(克唑替尼耐药)细胞,随机分为空白组(溶剂对照)、实验组(50 mg·kg-1地罗阿克)和对照组(50 mg·kg-1克唑替尼),每组9只,每天灌胃给药1次,连续给药14 d。用BALB/c裸鼠建立人肺癌肿瘤组织来源的LU-01-0319R(克唑替尼耐药)病人来源肿瘤异种移植(PDX)模型,随机分为空白组(溶剂对照)、实验组(24 mg·kg-1地罗阿克)和对照组(24 mg·kg-1克唑替尼),每组9只,每天灌胃给药1次,连续给药21 d。在BALB/c裸鼠颅内接种人源肺癌H228-luc细胞,随机分为空白组(溶剂对照)、实验组(100 mg·kg-1地罗阿克)和对照组(100 mg·kg-1克唑替尼),每组9只,每天灌胃给药1次,连续给药14 d。评价地罗阿克的抗肿瘤作用。

结果

地罗阿克对ALK、ALK-L1196M、ALK-G1202R激酶活性均有明显抑制作用[半数抑制浓度(IC50)均小于1.0 nmol·L-1]。地罗阿克对EML4-ALK融合的细胞株(NCI-H3122)具有显著的增殖抑制活性(IC50=3.00 nmol·L-1),对于具有EML4-ALK融合的细胞株以及克唑替尼和2代酪氨酸激酶抑制药(ALK-TKI)耐药突变株均具有较强的抑制活性(IC50:1.92~62.85 nmol·L-1)。在克唑替尼耐药的Ba/F3-EML4-ALK-L1196M异种移植模型上,50 mg·kg-1地罗阿克有显著的抗肿瘤作用,相对肿瘤增殖率为6.14%;在LU-01-0319R人源肺癌异种移植模型(克唑替尼耐药PDX模型)上,24 mg·kg-1地罗阿克有显著的抑瘤作用,相对肿瘤增殖率为13.19%;对于H228-luc人源肺癌颅内接种模型,100 mg·kg-1地罗阿克能够显著抑制肿瘤生长,肿瘤部位光学信号强度(BLI)值为(569.34±153.65)× 105 photons·s-1,且能显著延长动物的存活时间。

结论

地罗阿克能够很好地抑制ALK及多种一代、二代ALK-TKI的耐药突变,在多种肿瘤模型(包括颅内接种模型)中均表现出了显著的抗肿瘤作用。

Objective

To study the in vitro and in vivo pharmacodynamics of dirozalkib.

Methods

Prepare dirozalkib solutions with concentrations ranging from 3.81×10-3 to 1 000.00 nmol·L-1. The activities of dirozalkib against kinases anaplastic lymphoma kinase (ALK), ALK-L1196M, and ALK-G1202R were evaluated using the Mobility Shift Assay and Radioisotope Filter Binding methods. The inhibitory effect of dirozalkib on cell proliferation was evaluated using the CellTiter-Glo assay in multiple Ba/F3 cell lines transfected with EML4-ALK fusion genes and drug-resistant mutants, at concentrations ranging from 1.53×10-2 to 1 000.00 nmol·L-1. Ba/F3-EML4-ALK-L1196M (crizotinib-resistant) cells were subcutaneously inoculated in NOD SCID mice. The tumor-bearing mice were randomly divided into blank group (solvent control), experimental group (50 mg·kg-1 dirozalkib), control group (50 mg·kg-1 crizotinib), each group consisted of 9 mice. The mice were gavage once a day, continuous administration over a 14-day period. BALB/c nude mice were used to establish a human lung cancer tumor tissue-derived LU-01-0319R (crizotinib-resistant) patient-derived tumor xenograft (PDX) model. The tumor-bearing mice were randomly divided into blank group (solvent control), experimental group (24 mg·kg-1 dirozalkib), control group (24 mg·kg-1 crizotinib), each group consisted of 9 mice. The mice were gavage once a day, continuous administration over a 21-day period. Human lung cancer H228-luc cells were intracranially inoculated in BALB/c nude mice. The tumor-bearing mice were randomly divided into blank group (solvent control), experimental group (100 mg·kg-1 dirozalkib), control group (100 mg·kg-1 crizotinib), each group consisted of 9 mice. The mice were gavage once a day, continuous administration over a 14-day period. Assessed the anti-tumor efficacy of dirozalkib.

Results

Dirozalkib significantly inhibited the kinase activities of ALK, ALK-L1196M, and ALK-G1202R [50% inhibiting concentration (IC50) <1.0 nmol·L-1]. In cells, dirozalkib exhibited significant proliferation inhibitory activity against NCI-H3122 cells harboring EML4-ALK fusion (IC50 = 3.00 nmol·L-1). Additionally, it demonstrated potent inhibitory activity against multiple cell lines with EML4-ALK fusion and drug-resistant mutants of crizotinib and second-generation ALK inhibitors (IC50: 1.92-62.85 nmol·L-1). In the crizotinib-resistant Ba/F3-EML4-ALK-L1196M xenograft model, dirozalkib at a dose of 50 mg·kg-1 had a significant anti-tumor effect, with a relative tumor proliferation rate of 6.14%. In the LU-01-0319R human lung cancer xenograft model (crizotinib-resistant PDX model), the 24 mg·kg-1 dirozalkib also had a significant tumor inhibitory effect, with a relative tumor proliferation rate of 13.19%. For the H228-luc human lung cancer intracranial inoculation model, dirozalkib at 100 mg·kg-1 could significantly inhibit tumor growth [BLI value was (569.34±153.65) × 105 photons·s-1]and could significantly prolong the survival time of the animals.

Conclusion

Dirozalkib effectively inhibits ALK and various resistance mutations associated with first- and second-generation ALK-TKIs, and shows significant antitumor activity in multiple tumor models, including intracranial implantation models.
