Abstract

Thiazole esters are suitable for detecting the presence of leukocytes in urine. Such thiazole esters are suitable for use in compositions, diagnostic devices, and methods for detecting the presence of leukocytes. In one embodiment, a thiazole ester is of formula (I) or a salt or solvated salt thereof, in which A is an N-blocked amino acid residue or an N-blocked peptide chain, preferably N-blocked alanine or N-blocked polyalanine; and R1 is unsubstituted or substituted heteroaryl; alkenyl substituted with unsubstituted or substituted aryl; or alkenyl substituted with unsubstituted or substituted heteroaryl. For example, R1 may be thienyl, pyridyl, furyl, styryl, pyrrolyl, or indolyl. In still another embodiment, the thiazole ester includes unsubstituted or substituted fused hydrocarbyl rings as a substituent. In one embodiment, fused hydrocarbyl rings include naphthyl. In another embodiment, fused hydrocarbyl rings include anthryl.
