摘 要 目的 探究二氢色原酮拼接多环吡咯螺环氧化吲哚类化合物3m抗皮肤鳞状细胞癌的作用及机制。方法 以人皮肤鳞状
细胞癌 A431、Colo-16 细胞为研究对象,采用 CCK-8 法检测不同浓度(5、10、20、40、80 μmol/L)3m 作用 24、48、72 h 后对 A431、
Colo-16 细胞增殖的影响,并计算培养 48 h 时的半数抑制浓度(IC50 )。将 A431、Colo-16 细胞分别分为对照组和 3m 低、高浓度组
(15、30 μmol/L),加入相应药物或培养基培养48 h后,采用倒置显微镜观察细胞形态变化,检测细胞克隆形成率、迁移率、侵袭数、

细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)]磷酸化或表达水平及其mRNA的表达水平。结果 不同浓度3m作用24、48、72 h后
均能显著抑制A431、Colo-16细胞增殖(P<0.01),48 h时的IC50分别为20.36、23.72 μmol/L。作用48 h后,与对照组比较,3m低、高

ABSTRACT OBJECTIVE To study the effect and mechanism of dihydrochromone-spliced polycyclic pyrrole-spiroepoxidole
compound 3m on cutaneous squamous cell carcinoma. METHODS Using human cutaneous squamous cell carcinoma A431 and
Colo-16 cells as research subjects, CCK-8 assay was used to detect the effects of different concentrations of 3m (5, 10, 20, 40,
80 μmol/L) on the proliferation of A431 and Colo-16 cells after 24, 48 and 72 hours; the median inhibitory concentration (IC50 )
was calculated at 48 h of treatment. A431 and Colo-16 cells were divided into control group, 3m low-concentration and high-
concentration groups (15, 30 μmol/L). After treated with relevant drugs or culture medium for 48 h, the morphological changes of
cells in each group were observed by inverted microscope. Clone formation rate, migration rate and number of cell invasions, cell
cycle distribution and apoptosis rate were detected. The phosphorylation, or expression of Janus kinase 2/signal transducer and
activator of transcription 3 (JAK2/STAT3) signaling pathway related proteins [JAK2, STAT3, B-cell lymphocyte-2 (Bcl-2), Bcl-2-
associated X protein (Bax)], and their mRNA expression in cells were detected. RESULTS 3m could significantly inhibit the
proliferation of A431 and Colo-16 cells after treated for 24, 48, 72 h (P<0.01), and IC50 of them were 20.36, 23.72 μmol/L,
respectively. After 48 hours of treatment, compared with
