  • A modified synthesis and serological evaluation of neoglycoproteins containing the natural disaccharide of PGL-I from Mycobacterium leprae
    作者:Jian Zhang、Delphi Chatterjee、Patrick J. Brennan、John S. Spencer、Avraham Liav

    In order to generate substantial amounts of neoglycoconjugate needed for commercialization of diagnostic kits and high-throughput detection of leprosy, we developed a facile and high-yield synthesis of the corresponding disaccharide. Herein, the non-reducing disaccharide segment of phenolic glycolipid I from Mycobacterium leprae, O-(3,6-di-O-methyl-beta-D-glucopyranosyl)-(1 -> 4)-O-2,3-di-O-methyl-alpha-L-rhamnopyranose was synthesized by an improved procedure. The disaccharide was efficiently conjugated to bovine/human serum albumin, via acyl-azide intermediate, to form natural disaccharide-BSA/HSA neo-glycoproteins that showed a high activity in serodiagnosis of leprosy. The disaccharide incorporated into the proteins was accurately measured by MALDI-TOF mass spectrometry. The serological activities of the neoglycoproteins against pooled human lepromatous leprosy sera were measured by ELISA and they were detectable at picogram amounts. (C) 2010 Elsevier Ltd.
