摘要
天然产物是新药创制的重要来源,其靶点的识别及确证对阐明药物作用机制十分重要。常见的靶点识别和确证方法中,用探针标记天然产物的方法费时费力,可能会降低或改变天然产物的活性。近年来开发的无需对天然产物进行化学修饰的方法,逐渐成为天然产物靶点研究的重要手段。这些方法包括直接法和间接法,其中直接法主要基于蛋白质的亲和性、稳定性等原理,间接法则从生理反应或生化特征的改变推断药物靶点。本文对近年来非标记天然产物的靶点识别和确证研究中采用的方法进行综述,以期为天然产物靶点研究提供参考。
Natural products areone source of new drugs,and their target identification is pivotal forelucidating the mechanism of action.Most methods of target discovery and validation utilize labeling natural products with probes This is time-consuming and laborious,and often results in activity decrease or change of the natural products.Recent methods withoutchemicalmodificationhave become the main force in the target identification of natural products including direct or indirect methods.Direct methods are mainly based on the principle of affinity and stability of protein,and indirect methods infer the drug target from the change in physiological responses or biochemical signatures.This review summarizes recent methods for target identification and validation of label-freenatural products,providing new ideas and strategies for future research in natural products.
