That made the aminothiazoles look more like cholesterol

修饰后的氨噻唑分子看起来更像胆固醇分子。

This barrier interprets many putative drugs, including aminothiazoles, as harmful, and thus keeps them out.

可能有效的许多药物包括氨噻唑也被这个屏障当作有害物质阻挡在脑外。

Testing aminothiazoles in Petri dishes is, however, rather different from testing them on living animals.

但是，检验发现氨噻唑在活动物体内的作用与在体外培养细胞中的作用大不相同。

Dr Renslo and his colleagues have therefore been analysing and modifying the chemical structure of aminothiazoles to see if this can enable them to cross the blood-brain barrier.

为此，Renslo博士与其同事已经在分析并尝试修饰氨噻唑的分子结构，以使之能通过血脑屏障。
