本文着重选择性地论述最近三年内发表的已阐明结构的生物活性物质。传统来源的激素、抗肿瘤剂和抗生素不包括在内。由于天然产物是从正常的初级代谢库经酶控生成,因此它们要比由纯粹化学想象合成的许多产物更容易与其他生物聚合体例如受体密切相互作用。生物活性天然产物尚为其它目的而精确制备,因而一般天然产物本身未必在临床使用,但作为化学线索,采用近代药物设计原理并加以精制则可导致药物研究和临床进展的新途径。非甾体抗炎剂来源于高等植物中许多有价值的非甾体抗 This article focuses on selectively addressing the elucidated structures of bioactives published in the last three years. Traditional sources of hormones, antineoplastic agents and antibiotics are not included. Because natural products are enzymatically produced from normal primary metabolites, they interact more easily with many other biopolymers, such as receptors, than many products synthesized by purely chemical imagination. Bioactive natural products are also precisely prepared for other purposes, so the natural products themselves are not necessarily in clinical use, but as a chemical clues, using modern drug design principles and refining can lead to new ways of drug research and clinical progress. NSAIDs come from many valuable non-steroidal anti-inflammatory drugs in higher plants
