Novel non-nucleoside tricyclic platelet ADP receptor (P2Y(12)) antagonists have been discovered that bind reversibly and with high affinity to the platelet receptor. Condensation of various 2-aminobenzothiazoles with chlorosulfonylacetyl chloride affords these novel tricyclic heterocycles, which are novel and unpredicted products

A method has been developed for de novo peptide sequencing using matrix-assisted laser desorption ionization mass spectrometry. This method will facilitate biological studies that require rapid determination of peptide or protein sequences, e.g., determination of posttranslational modifications, identification of active
