近些年来,来自勘萨斯大学医学中心的癌症生物学系的研究人员一直在研究番红花酸对胰腺癌的作用。番红花酸来自藏红花,一种流行的香料和食品着色剂,是很多印度传统药物的关键成分。

据发表于Oncotarget的一项新的研究表明,Crocetinic酸——从番红花酸中纯化出来的复合物,可抑制胰腺癌细胞的生长。

Animesh Dhar博士说道,应用Crocetinic酸21天后,小鼠皮下的胰腺癌组织生长明显减慢。“相比于未接受Crocetinic酸治疗的小鼠,接受Crocetinic酸治疗的小鼠其癌组织的生长速度下降了75%,未接受Crocetinic酸治疗的小鼠其癌组织体积增加了250%”

胰腺癌是最致命的癌症之一,是美国群众因癌症死亡的第四大病因,每年超43000人诊断出患有胰腺癌,且每年因胰腺癌死亡的人数也约43000人。目前仅有3%的胰腺癌患者在确诊后可存活5年以上。

KU医学中心的试验表明,Crocetinic酸可靶向并抑制胰腺癌干细胞——通常可抗传统化疗药物的一群致死性的细胞。

“除非破坏这些细胞,否则癌症还可复发,” Shrikant Anant博士说道,“如果我们可以确定Crocetinic酸可成功的抑制或破坏这些干细胞,那么这将是胰腺癌治疗上的一大进步。
