为了开发灵丹妙药,一些制药公司不惜投入大量资源遍地找寻。然而,只需把我们的视界停留在自身的肠道内,那儿有数千种不断产生和释放生物活性分子的细菌——制药公司赖以生存的由不同化学成分组成的小分子混合物。比较典型是高级生物体内的类固醇与肽类激素,其中蕴含着许多重要的生物学功能。 In order to develop panacea, some pharmaceutical companies have invested heavily in search of resources. However, we simply leave our field of vision within our own gut, where there are thousands of small molecule mixtures of different chemistries that the pharmaceutical companies rely on to keep producing and releasing bioactive molecules. Typical are steroids and peptide hormones in higher organisms, which contain many important biological functions.
