Passage | JAK/STAT Signaling |
Background | Cryptotanshinone can inhibit STAT3 and has antitumor activity. |
Biological Activity | Cryptotanshinone是从丹参的根中提取的天然化合物, 具有抗肿瘤活性。 Cryptotanshinone抑制 STAT3 的 IC50 为4.6 μM[1-4]。 |
IC50 | STAT3:4.6μM (IC50) [1-4] |
In Vitro | 与不显示活性的丹参酮IIA相比,隐丹参酮显着抑制STAT3依赖性荧光素酶活性,STAT3 Tyr705磷酸化和STAT3的二聚化。隐丹参酮(7μM)显着阻断DU145细胞中STAT3 Tyr705磷酸化但不抑制STAT3 Ser727磷酸化,并且显着抑制JAK2磷酸化,IC50为5μM,而不影响上游激酶c-Src和EGFR的磷酸化,表明抑制STAT3 Tyr705磷酸化可能是由于直接机制可能通过绑定到STAT3的SH2域。隐丹参酮通过阻断STAT3活性显着抑制具有组成型活性STAT3且GI50为7μM的DU145前列腺癌细胞的增殖,其导致细胞周期蛋白D1,Bcl-xL和存活蛋白的下调,随后在G0-G1中积累。相。隐丹参酮对PC3,LNCaP和MDA-MB-468细胞的生长抑制作用较小[1]。隐丹参酮显着减弱了DEX对卵巢的体外激素作用,如T的显着降低和培养基中P水平的增加所示。隐丹参酮可显着提高DEX处理卵巢中磷酸化AKT2和GSK3β的水平[2]。伊马替尼和隐丹参酮的联合治疗在伊马替尼敏感和耐药CML细胞系以及原发性CML细胞中均显示出显着的协同杀伤作用[3]。 |
In Vivo | Cryptotanshinone逆转卵巢IR并显着增加来自DEX处理的小鼠的所有检查组织中的2-脱氧-D- [1,2-3H] - 葡萄糖摄取。隐丹参酮可显着降低排卵率和血浆E2和P水平[2]。隐丹参酮给药以剂量依赖性方式显着降低ob / ob小鼠(C57BL / 6J-Lepob)和饮食诱导的肥胖(DIO)小鼠的体重和食物摄入。隐丹参酮在脂肪组织中引起明显较少的脂肪,血清甘油三酯和胆固醇水平显着降低,并且骨骼肌的AMPK活性比对照小鼠高2.5至3倍。以600mg / kg /天口服给予隐丹参酮可显着降低ob / ob小鼠(C57BL / 6J-Lepob),db / db小鼠(C57BL / KsJ-Leprdb)和ZDF大鼠的血糖水平,3天,并持续整个监测期[4]。 |
Cell Experiment | 如前所述,MTT测定用于评估细胞生长抑制。将细胞以每孔8000个细胞的密度接种在含有10%FBS的RPMI-1640的96孔板中。加入不同浓度的伊马替尼和CPT并再孵育24小时。然后,向每个孔中加入20μLMTT,并在酶联免疫吸附测定(ELISA)读板仪上测量570nm处的吸光度。根据先前的研究确定伊马替尼和CPT之间的药物相互作用系数(CDI)。计算方法如下:CDI / AB /(A×B)。根据各组的吸光度,AB为组合组与对照组的比例; A或B是单一药剂组与对照组的比率。 CDI 1表示拮抗作用。在组合治疗组中,CPT的浓度根据50%抑制浓度(IC50)值任意指定。然后,在用不同浓度的伊马替尼加CPT(一种细胞类型的恒定CPT浓度)处理后测定细胞活力。最后,计算伊马替尼的组合IC 50值,并在表I中表示。原发性CML细胞CP1至CP3分离自慢性期患者,而BC1和BC2分离自急变期患者。进行三组独立的实验。 IC50值表示为平均值±标准偏差(SD)。 |
Kinase Experiment | 用具有STAT3结合元件的报告质粒瞬时转染HCT-116细胞以调节荧光素酶测定。用Cryptotanshinone处理细胞24小时,浓度范围为0.2至50μM。处理后,在20μL被动裂解缓冲液中收获细胞,并通过Wallac Victor2上的Dual Luciferase Reporter Assay试剂盒评估荧光素酶活性。抑制荧光素酶活性50%的隐丹参酮的浓度代表IC 50值。 |
