At the moment, there are several other commercially available proton pump inhibitors. However, they are not as susceptible to conversion into active forms?
目前，也有其他一些市面上买得到的质子泵抑制剂。然而，他们不是一样容易转换为活化形式吗？

The prodrug exposed to strong acid is protonated and undergoes a conformational change to its active form which is capable of inhibiting the proton pump.
前药的接触了强酸后被质子化，并且经过结构的改变成为真正能够抑制质子泵的活化形式。

To explore the role of the bridged N atom for a possible proton transfer in the active site of hydrogenase, we tried to introduce a hydrogen bond into a couple of designed molecules.
