Objective

To investigate the antitumor activity and mechanism of a pyrazole [1,5-a]pyrimidine derivative (BPPA) on human tongue squamous cell carcinoma Cal33 cells.

Methods

Cal33 cells were divided into blank group (normal culture), experimental-L, -M, -H groups (1, 2.5 and 5 μmol·L-1BPPA) and combined group [2.5 μmol·L-1BPPA and 5 mmol·L-1 N-acety-L-cysteine (NAC)]. Cell viability was determined by thiazole blue assay. Cell apoptosis was measured using flow cytometry, while apoptosis-related protein expression levels were determined by Western blot analysis. Changes in reactive oxygen species and mitochondrial membrane potential were evaluated using immunofluorescence assay.

Results

The survival rates of Cal33 cells in blank, experimental-L,-M,-H and combined groups were (99.56±0.91)%, (58.31±2.31)%, (47.93±1.67)%, (29.35±4.11)% and (70.27±1.21)%, respectively; cell apoptotic rates were (8.07±1.01)%, (44.04±0.94)%, (49.85±1.75)%, (66.79±0.83)% and (24.33±1.04)%, respectively; the relative fluorescence intensities of reactive oxygen species (ROS) were 1.23±0.21, 3.37±0.35, 15.53±1.46, 20.28±1.24 and 5.59±0.52, respectively; the mitochondrial membrane potential red fluorescence/green fluorescence values were 4.69±0.11, 4.24±0.12, 0.86±0.16, 0.46±0.05 and 2.99±0.11, respectively. Compared with blank group, the above indexes in the experimental-L, -M, -H groups were statistically significant (P<0.01, P<0.001). Compared with experimental-M group, the above indexes in combined group were statistically significant (P<0.01, P<0.001). The relative levels of pro-apoptotic B-cell lymphoma-2 (Bcl-2)-Associated X protein (Bax) in blank, experimental-L,-M,-H groups were 1.00±0.02, 1.94±0.03, 3.73±0.06 and 4.64±0.08, respectively; the relative levels of anti-apoptotic protein Bcl-2 were 1.00±0.02, 0.75±0.04, 0.62±0.02 and 0.46±0.03, respectively. Compared with blank group, the above indexes in the experimental-L, -M, -H groups were statistically significant (P<0.01, P<0.001).

Conclusion

BPPA exhibits anti-head and neck cancer activity by ROS mediating the decrease in mitochondrial membrane potential, thereby inducing apoptosis.

目的

探讨新型吡唑[1,5-a]嘧啶衍生物(BPPA)对人舌鳞状癌细胞Cal33的抗肿瘤活性及作用机制。

方法

将Cal33细胞分为空白组(正常培养)、低、中、高剂量实验组(1、2.5、5 μmol·L-1 BPPA)及联合组[2.5 μmol·L-1 BPPA和5 mmol·L-1 N-乙酰-L-半胱氨酸(NAC)]。用噻唑蓝法检测BPPA对肿瘤细胞的存活率;用流式细胞术检测细胞的凋亡情况;用蛋白质印迹法检测凋亡相关蛋白相对表达水平;用免疫荧光分析活性氧及线粒体膜电位的变化情况。

结果

空白组、低、中、高剂量实验组及联合组的Cal33细胞存活率分别为(99.56±0.91)%、(58.31±2.31)%、(47.93±1.67)%、(29.35±4.11)%和(70.27±1.21)%,凋亡率分别为(8.07±1.01)%、(44.04±0.94)%、(49.85±1.75)%、(66.79±0.83)%和(24.33±1.04)%;活性氧检测的相对荧光强度分别为1.23±0.21、3.37±0.35、15.53±1.46、20.28±1.24和5.59±0.52,线粒体膜电位红色荧光/绿色荧光值分别为4.69±0.11、4.24±0.12、0.86±0.16、0.46±0.05和2.99±0.11。低、中、高剂量实验组上述指标与空白组比较,联合组上述指标与中剂量实验组比较,在统计学上差异均有统计学意义(P<0.01,P<0.001)。空白组和低、中、高剂量实验组促凋亡蛋白B淋巴细胞瘤-2基因相关X蛋白(Bax)相对表达水平分别为1.00±0.02、1.94±0.03、3.73±0.06和4.64±0.08,同时抑制凋亡蛋白B淋巴细胞瘤-2基因蛋白(Bcl-2)的相对表达水平分别为1.00±0.02、0.75±0.04、0.62±0.02和0.46±0.03。低、中、高剂量实验组上述指标与空白组比较,在统计学上差异均有统计学意义(P<0.01,P<0.001)。

结论

化合物BPPA具有抗头颈癌活性,其机制是通过促进活性氧生成介导线粒体膜电位降低诱导细胞凋亡导致肿瘤死亡。

目的

探讨新型吡唑[1,5-a]嘧啶衍生物(BPPA)对人舌鳞状癌细胞Cal33的抗肿瘤活性及作用机制。

方法

将Cal33细胞分为空白组(正常培养)、低、中、高剂量实验组(1、2.5、5 μmol·L-1 BPPA)及联合组[2.5 μmol·L-1 BPPA和5 mmol·L-1 N-乙酰-L-半胱氨酸(NAC)]。用噻唑蓝法检测BPPA对肿瘤细胞的存活率;用流式细胞术检测细胞的凋亡情况;用蛋白质印迹法检测凋亡相关蛋白相对表达水平;用免疫荧光分析活性氧及线粒体膜电位的变化情况。

结果

空白组、低、中、高剂量实验组及联合组的Cal33细胞存活率分别为(99.56±0.91)%、(58.31±2.31)%、(47.93±1.67)%、(29.35±4.11)%和(70.27±1.21)%,凋亡率分别为(8.07±1.01)%、(44.04±0.94)%、(49.85±1.75)%、(66.79±0.83)%和(24.33±1.04)%;活性氧检测的相对荧光强度分别为1.23±0.21、3.37±0.35、15.53±1.46、20.28±1.24和5.59±0.52,线粒体膜电位红色荧光/绿色荧光值分别为4.69±0.11、4.24±0.12、0.86±0.16、0.46±0.05和2.99±0.11。低、中、高剂量实验组上述指标与空白组比较,联合组上述指标与中剂量实验组比较,在统计学上差异均有统计学意义(P<0.01,P<0.001)。空白组和低、中、高剂量实验组促凋亡蛋白B淋巴细胞瘤-2基因相关X蛋白(Bax)相对表达水平分别为1.00±0.02、1.94±0.03、3.73±0.06和4.64±0.08,同时抑制凋亡蛋白B淋巴细胞瘤-2基因蛋白(Bcl-2)的相对表达水平分别为1.00±0.02、0.75±0.04、0.62±0.02和0.46±0.03。低、中、高剂量实验组上述指标与空白组比较,在统计学上差异均有统计学意义(P<0.01,P<0.001)。

结论

化合物BPPA具有抗头颈癌活性,其机制是通过促进活性氧生成介导线粒体膜电位降低诱导细胞凋亡导致肿瘤死亡。

Objective

To investigate the antitumor activity and mechanism of a pyrazole [1,5-a]pyrimidine derivative (BPPA) on human tongue squamous cell carcinoma Cal33 cells.

Methods

Cal33 cells were divided into blank group (normal culture), experimental-L, -M, -H groups (1, 2.5 and 5 μmol·L-1BPPA) and combined group [2.5 μmol·L-1BPPA and 5 mmol·L-1 N-acety-L-cysteine (NAC)]. Cell viability was determined by thiazole blue assay. Cell apoptosis was measured using flow cytometry, while apoptosis-related protein expression levels were determined by Western blot analysis. Changes in reactive oxygen species and mitochondrial membrane potential were evaluated using immunofluorescence assay.

Results

The survival rates of Cal33 cells in blank, experimental-L,-M,-H and combined groups were (99.56±0.91)%, (58.31±2.31)%, (47.93±1.67)%, (29.35±4.11)% and (70.27±1.21)%, respectively; cell apoptotic rates were (8.07±1.01)%, (44.04±0.94)%, (49.85±1.75)%, (66.79±0.83)% and (24.33±1.04)%, respectively; the relative fluorescence intensities of reactive oxygen species (ROS) were 1.23±0.21, 3.37±0.35, 15.53±1.46, 20.28±1.24 and 5.59±0.52, respectively; the mitochondrial membrane potential red fluorescence/green fluorescence values were 4.69±0.11, 4.24±0.12, 0.86±0.16, 0.46±0.05 and 2.99±0.11, respectively. Compared with blank group, the above indexes in the experimental-L, -M, -H groups were statistically significant (P<0.01, P<0.001). Compared with experimental-M group, the above indexes in combined group were statistically significant (P<0.01, P<0.001). The relative levels of pro-apoptotic B-cell lymphoma-2 (Bcl-2)-Associated X protein (Bax) in blank, experimental-L,-M,-H groups were 1.00±0.02, 1.94±0.03, 3.73±0.06 and 4.64±0.08, respectively; the relative levels of anti-apoptotic protein Bcl-2 were 1.00±0.02, 0.75±0.04, 0.62±0.02 and 0.46±0.03, respectively. Compared with blank group, the above indexes in the experimental-L, -M, -H groups were statistically significant (P<0.01, P<0.001).

Conclusion

BPPA exhibits anti-head and neck cancer activity by ROS mediating the decrease in mitochondrial membrane potential, thereby inducing apoptosis.
