Synthesis of an arabinofuranosyl disaccharide photoaffinity probe for arabinosyltransferase activity in Mycobacterium tuberculosis

(5-Azidonaphthalene-1-sulfonamidoethyl)-5-O-(α–arabinofuranosyl)-α- -arabinofuranoside 1 was synthesized as a photoaffinity probe for the determination of arabinosyl transferase activity and for the identification of binding and functional sites in Mycobacterium tuberculosis.
