十年磨一剑,开辟“影像诊断”新蓝海
2017-08-25 08:46:43 中国青年网
12年踏实创新,孙伟燕和他的团队用自己的坚守诠释了药物研究人的毅力,也以创业者的身份开辟了“影像诊断”市场新的蓝海。2016年4月,在世界分子影像航天生理医学吉隆坡大会上,由孙伟燕团队研发的“18氟代胸腺嘧啶”一举荣获“达图朱丽欧奖”最佳墙报奖,这也是我国首次在这一世界级影像诊断会议中获得奖项。尽管获得如此高的荣誉,孙伟燕也没有停下研究的脚步。在原有成果的基础之上,医影团队乘胜追击,创造性的用同位素19氟和具有放射性的同位素18氟来修饰核酸,研制出诊断与化学治疗“二合一”的胸苷环磷酸酯化合物。
“在同一个核酸中18氟用于诊断,19氟用于治疗。尽管它的价格是黄金的1000倍,但真正应用于临床时个体的成本还是相对低的,这种药物已获得国家发明专利授权。”在位于江苏省医疗器械产业园内的医影实验室里,孙伟燕指着从冰箱里取出一个小瓶向记者介绍, 胸苷环磷酸酯化合物的发明不仅改变了先不清楚抗肿瘤药物有无效果,在哪里发挥药效的困境,更有助于重新审视、探索抗肿瘤药物的作用机制,对于提高抗肿瘤药物的效果与研发有重要的意义。
“这种药与基因治疗搭配使用,可进一步提高治疗的效果。此外,‘二合一’新药主要活性成分由于能实时跟踪抗肿瘤药物的走向,只要药物到达癌症病灶,便能很快测出病灶的位置并进行治疗。尤其是在肺癌与脑癌的诊断、治疗方面,相对于其他药物,更具有市场前景。”孙伟燕说。
目前,孙伟燕和他的团队还关注脑科学、退行性疾病等前沿学术的研究。同时,他们已向相关医院、大学、癌症研究所提供自主创新分子探针前体及相关技术。截至目前,已申报了5项发明专利,涉及核医学、肿瘤学、靶向药物和分子探针等创新药领域。
