What is Amilorine?

Short answer: it doesn't exist.

Long explanation: At last count there are 904 hits of "amilorine" on Google. However, there's absolutely no mentioning of it in any major scientific databases, e.g. SciFinder, Web of Science. Well, there is one find on Google Scholar. Those folks said another group studied "amilorine-sensitive channels". The group they cited, it turns out, was talking about "amiloride-sensitive channel" instead. So that only one was probably a typo.

Back in 2002, somebody did a research on the propagation of citation errors in science, and estimated that about 20% folks cite articles without reading the original. Guess the percentage is higher in online news...
