protected amino acids (Trp, Tyr, Phe, and Lys) with various diamino spacers, as quenchers of the tripletexcited state of tiaprofenic acid (and its methyl ester), has been investigated. A series of quenching constants have been determined, which depend on the nature of the quencher and on the stereochemistry of the excited drug. A significant degree of stereodifferentiation has been found for the peptidomimetic
