The result was acetylsalicylic acid, the modern active ingredient in aspirin.

结果就是乙酰水杨酸，阿司匹林的性分。

So, the active ingredient in aspirin is a compound called acetylsalicylic acid.

阿司匹林的性分是一种叫做乙酰水杨酸的化合物。

Soon, aspirin became synonymous with acetylsalicylic acid.

很快，阿司匹林就了乙酰水杨酸的名词。

In 1853, a French chemist managed to chemically synthesize the compound, creating a substance called acetylsalicylic acid.

1853 年， 一位法国化学地化学合了这种化合物，产生了一种叫做乙酰水杨酸的物质。

Now if you swap the methyls out for a couple of other slightly more complicated groups, then you get acetylsalicylic acid, or aspirin.

在， 如果将甲基换其他几个稍微复杂一些的基团，就会得到乙酰水杨酸或阿司匹林。

And thus, we can build the compounds we need, whether it be the simple stuff, like acetylsalicylic acid, aspirin, or something more complicated, like alpha-(5,6-dimethylbenzimidazolyl)cobamidcyanide, better known as vitamin B12.

因此，我们可以构建我们需要的化合物， 无论是简单的东西， 如乙酰水杨酸、阿司匹林，还是更复杂的东西， 如 α-(5, 6-二甲基苯并咪唑基)cobamidcyanide， 也就是众所周知的维生素 B12。
