小分子与天然产物药物发现
SS一篇关于小分子和天然产物的蛋白相关性的文章http://pubs.acs.org/doi/pdf/10.1021/ja102798t又激起挺SS(自称Schreiberphile)和倒SS的激烈争论 。
SS本篇主要认为天然产物分子活性高,蛋白命中率高,与较多的蛋白相关,而小分子则
相反,虽然命中率低,其与较少的蛋白相关,因此最后强烈暗示自己的 DOS策略的意义
,一般收集的小分子结构太简单很难命中靶点,天然产物如此篇文章所言命中太多靶点
,DOS刚好满足小分子但结构更多,似乎对于寻找药物分子是个很好的选择。文章没仔
细读,对研究手段不太了解,感觉主要是些数据挖掘和统计分析的工作。
此篇文章的内容提出比尝试解决以下几个药物发现长期思考的问题,第一个就是小 |

Every natural product has its function/meaning to be there after million/
billion years of evolution. It is just people don't know the exact function
YET. Let alone how to use them (the application). People's knowledge
towards nature is so limited that they are sometimes too ignorant to study
them.
As to small molecules, large number of them do not have biological function.
However, we can rationally create or screen functional small m |

natural products are very simple in structure. |
