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

结果就是乙，司匹林现活性成分。

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

司匹林活性成分是一种叫做乙化合物。

Soon, aspirin became synonymous with acetylsalicylic acid.

很快，司匹林就成了乙名词。

Can't you put me back on 5ASA?

不能给我开点儿乙吗？

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

1853 年， 一位法国化学家成功地化学合成了这种化合物，产生了一种叫做乙物质。

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

现在， 如果将甲基换成其他几个稍微复杂一些基团，就会得到乙或司匹林。

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化合物， 无论是简单东西， 如乙、司匹林，还是更复杂东西， 如 α-(5, 6-二甲基苯并咪唑基)cobamidcyanide， 也就是众所周知维生素 B12。
