绿茶中的一种主要成分能够作为抗癌蛋白载体,用来合成一种稳定、有效的治疗用纳米复合物。在线发表于《自然-纳米技术》上的这项发现或有助于建立更好的药物投递系统。一些癌症治疗方法的效果依赖于药剂中的治疗成分和将药物投递至肿瘤位置的载体。设计药物载体时,有几个因素必须考虑:首先,其必须具有特定性,这样才能针对肿瘤而不伤及其他组织;其次,药物与载体的配比也很重要,因为如果身体无法代谢载体的话,载体剂量过高可能导致中毒;再者,如果身体对药物的排斥、消耗过快,会让药物失效。
A major component of green tea can be used as an anti-cancer protein carrier for the synthesis of a stable and effective therapeutic nanocomposite. This discovery, published online in Nature - Nanotechnology, may help to create better drug delivery systems. The effectiveness of some cancer treatments depends on the therapeutic ingredients in the agent and on the carrier that delivers the drug to the site of the tumor. There are several factors that must be considered when designing a drug carrier: First, it must be specific so that it can target the tumor without harming other tissues. Second, the drug to carrier ratio is also important because if the body can not metabolise the carrier , Too high a carrier dose may lead to poisoning. Moreover, if the body repels drugs and consumes too fast, the medicine will fail.
