ESR spectra of membrane spin probes are conventionally used to obtain structural information. Here we show, for the first time, that when a membrane-soluble compound undergoes a chemical reaction, time-dependent changes in the ESR spectra of membrane spin probes can

Gastrointestinal (GI) toxicity is a major drawback of the chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs). The NSAIDs topical actions on the protective phospholipid layers of the GI mucosa seem to be a central toxicity mechanism of these pharmaceuticals. This

A strategy to locate spectroscopic probes in micelles is presented which involves establishing a "benchmark" probe, i.e., one whose position is well-known and against which other probe positions may be established. Theoretically calculated values of the fraction of the micelle
