据新华社电,英国和巴西研究人员合作完成的一项新研究显示,繁殖于巴西的一种黄蜂能产生一种毒液,其中所含物质可有效对抗癌细胞却不伤及正常细胞,未来有望基于此研发出新的抗癌药物

这种学名为“Polybiapaulista”的黄蜂在遇到捕食者时,为保护自己尾部会分泌出一种毒液,这种毒液含有一种名为“MP1”的毒素,而这种物质具有抗癌作用。

英国利兹大学和巴西圣保罗州立大学的研究人员分析后发现,“MP1”能与癌细胞表面的脂质产生作用,从而在细胞上形成开口,让那些在细胞中发挥关键作用的分子外泄。

在实验室测试中,研究人员观察到,这种毒素能抑制前列腺癌、膀胱癌、甚至白血病等的癌细胞生长,并且还不会伤及正常细胞。

但研究人员也说,目前还不清楚这种毒素如何做到这种“选择性猎杀”,这或许与癌细胞膜的性质有关。

利兹大学的研究人员保罗・比尔斯说,如果能了解“MP1”的作用机制,并证实它的安全性,就能利用这种物质开发出比传统药物疗效更好的抗癌新药。
