Gramicidin derivatives as membrane-based pH sensors.
Ion channels provide a means for sensitive pH measurement at membrane interfaces. Detailed knowledge of the structure and function of gramicidin channels permits the engineering of pH-sensitive derivatives. Two derivatives, gramicidin-ethylenediamine and gramicidin-histamine, are shown to exhibit pH-dependent single-channel behaviour over the pH ranges 9-11 and 6.5-8.5, respectively. Thermal isomerization of a carbamate group at the entrance of the channels leads to a pattern of steps in single-channel recordings. The size of the steps depends on the time-averaged degree of protonation of the appended group (ethylenediamine or histamine). Measurement of the size of the steps thus permits single-molecule pH sensing under symmetrical pH conditions or in the presence of a pH gradient.

The significance of ethylenediamine hydrochloride dermatitis caused by a "generic" nystatin-triamcinolone II cream.
Generic Myco-Triacet II Cream would seem to be analogous to Mycolog II Cream. However, Myco-Triacet II Cream still contains the common and potent sensitizer, ethylenediamine hydrochloride, which is no longer present in Mycolog II Cream. This is another instance in which a rose by an other name does not smell as sweet.
