中国海洋药物研发现状堪忧 向海洋要药咋这么难?

  向海洋要药,咋就这么难

  ——我国海洋药物研发现状堪忧

“这么大一个国家,重磅海洋药物一个也没有,如何说得过去?”

在国内进行了大量调研之后,中科院海洋所研究员史大永感到既失望又无奈。4月19日,在山东省科协承办的山东省智库高端人才研修班暨新旧动能转换创新峰会上,他向现场数百名科技系统的专家、官员分享了一组数据,作为问题的注脚:

“国际上有13个海洋药物被美国FDA或欧洲EMEA批准上市,用于抗肿瘤、抗病毒及镇痛等。而我国一项也没有。”

“发达国家投入海洋药物研发不惜成本,比如日本每年投入3亿多美元,欧共体海洋科学中心每年4亿多美元,而我国只有5000万元人民币,约800万美元。”

一个“艰难的胜利”

海洋作为地球上最大的特殊生态系统,由于生存环境特殊,海洋生物为创新药物研究提供了丰富而独特的基因资源与化合物资源。

“‘ET-743’是从加勒比海鞘中分离得到的一种药物,用于治疗软组织肉瘤。”在接受科技日报记者专访时,史大永举例说,从最开始研究到被欧盟和美国FDA批准上市,“ET-743”走过了38年的艰苦历程,耗资近20亿美元,“它代表了海洋药物史上一个‘艰难的胜利’”。

对比“ET-743”这个标杆,我国不少团队正在追赶的路上。

这几年,让人印象深刻的突破来自中科院上海药物所耿美玉教授团队。这支团队对海洋糖类物质有着深厚的感情和独特的认识。经过17年努力,其海洋药物“971”已进入Ⅲ期临床研究,这是国际上第一个靶向Aβ分子的抗老年痴呆寡糖类药物;如果后期能通过美国FDA或欧洲EMEA批准,它有望成为我国第一个走向国际且具有自主知识产权的海洋药物。
