Prostate:咖啡醋酸二萜和咖啡醇能够抑制前列腺癌细胞的增殖和迁移

2019-01-08 AlexYang MedSci原创

咖啡能够抑制前列腺癌的恶化,然而,咖啡通过怎样的机制来对前列腺癌细胞产生作用的仍旧不清楚。最近,有研究人员鉴定了咖啡的关键化合物,这些化合物具有抗癌作用并且还调查了这些化合物的作用机制。研究人员对咖啡中的6种活性物质的抗增殖和抗迁移作用进行了评估,包括醋酸卡瓦醇, 咖啡醇,咖啡因,咖啡因酸,绿原酸和盐酸葫芦巴碱。研究发现,在评估的化合物中,只有醋酸卡瓦醇和咖啡醇能够以剂量依赖的方式抑制前列腺癌细胞

咖啡能够抑制前列腺癌的恶化,然而,咖啡通过怎样的机制来对前列腺癌细胞产生作用的仍旧不清楚。最近,有研究人员鉴定了咖啡的关键化合物,这些化合物具有抗癌作用并且还调查了这些化合物的作用机制。

研究人员对咖啡中的6种活性物质的抗增殖和抗迁移作用进行了评估,包括醋酸卡瓦醇, 咖啡醇,咖啡因,咖啡因酸,绿原酸和盐酸葫芦巴碱。研究发现,在评估的化合物中,只有醋酸卡瓦醇和咖啡醇能够以剂量依赖的方式抑制前列腺癌细胞的增殖和迁移。醋酸卡瓦醇和咖啡醇的组合治疗能够协同抑制前列腺癌细胞的增殖和迁移,并且诱导细胞凋亡,抑制上皮间质转化和减少雄激素受体,从而导致雄激素受体阳性细胞中核雄激素受体的减少。更多的是,醋酸卡瓦醇和咖啡醇能够下调CCR2和CCR5的表达,并增加它们的配体CCL2和CCL5的表达。异种种植研究表明了口服醋酸卡瓦醇和咖啡醇能够显著的抑制肿瘤的生长。

最后,研究人员指出,醋酸卡瓦醇和咖啡醇能够协同的抑制前列腺癌的恶化。这些咖啡复合物可能是前列腺癌治疗的新候选药物。
