Synthesis of the trisaccharide repeating unit of capsular polysaccharide from Klebsiella pneumoniae

The incidences of primary, pyrogenic liver abscess complicated by meningitis and septic endophthalmitis caused by Klebsiella pneumoniae has increased globally. Earlier studies have shown that the capsular polysaccharide (CPS) of Klebsiella pneumoniae plays an important role in the resistance to phagocytosis and related pathogenicity. The first chemical synthesis of the trisaccharide repeating unit of this CPS has been achieved via stereoselective glycosylation with orthogonal and appropriate protecting groups. A new method for the pyruvylation of trans diol was developed.

Chemical Approach to Positional Isomers of Glucose-Platinum Conjugates Reveals Specific Cancer Targeting through Glucose-Transporter-Mediated Uptake in Vitro and in Vivo

Glycoconjugation is a promising strategy for specific targeting of cancer. In this study, we investigated the effect of d-glucose substitution position on the biological activity of glucose-platinum conjugates (Glc-Pts). We synthesized and characterized all possible positional isomers (C1α, C1β, C2, C3, C4, and C6) of a Glc-Pt. The synthetic routes presented here could, in principle, be extended to prepare glucose conjugates with different active ingredients, other than platinum. The biological activities of the compounds were evaluated both in vitro and in vivo. We discovered that varying the position of substitution of d-glucose alters not only the cellular uptake and cytotoxicity profile but also the GLUT1 specificity of resulting glycoconjugates, where GLUT1 is glucose transporter 1. The C1α- and C2-substituted Glc-Pts (1α and 2) accumulate in cancer cells most efficiently compared to the others, whereas the C3-Glc-Pt (3) is taken up least efficiently. Compounds 1α and 2 are more potent compared to 3 in DU145 cells. The α- and β-anomers of the C1-Glc-Pt also differ significantly in their cellular uptake and activity profiles. No significant differences in uptake of the Glc-Pts were observed in non-cancerous RWPE2 cells. The GLUT1 specificity of the Glc-Pts was evaluated by determining the cellular uptake in the absence and in the presence of the GLUT1 inhibitor cytochalasin B, and by comparing their anticancer activity in DU145 cells and a GLUT1 knockdown cell line. The results reveal that C2-substituted Glc-Pt 2 has the highest GLUT1-specific internalization, which also reflects the best cancer-targeting ability. In a syngeneic breast cancer mouse model overexpressing GLUT1, compound 2 showed antitumor efficacy and selective uptake in tumors with no observable toxicity. This study thus reveals the synthesis of all positional isomers of d-glucose substitution for platinum warheads with detailed glycotargeting characterization in cancer.

A series of 2,3-di-O-benzoyl-D-galctopyranosides, α-allyl (5), α-benzyl (6), β-ethyl-1-thio (7), β-phenyl-1-thio (8), and α-methyl (9), were prepared from the corresponding 4,6-O-benzylidene derivatives and were acetalated in acetonitrile with methyl pyruvate, to give diastereoselectively the 2,3-di-O-benzoyl-4,6-O--D-galactopyranosides 10-16.The latter were converted into the 2,3-di-O-benzoyl-4,6-O--D-galactopyranosyl α- and β-trichloroacetimidates 19 and 20, α- and β-fluorides 21 and 22, the α-bromide 23, and the α-chloride 24, respectively.These donors, including the phenyl 1-thiogalactoside 14, reacted with 5-pentanol to give the corresponding protected β-D-galactoside 27, deblocking of which afforded the title compound 1.Binding of 1 to epoxypropyl-modified acrylamide beads gave an affinity adsorbent that was used to isolate serum amyloid P protein from human serum.
