专利号:US-2011015119-A1 优先权日:2009-06-24 标题:Novel semi-synthetic glycopeptides as antibacterial agents 发明人:CHU DANIEL; YE TAO; WANG BING 权利人:LEAD THERAPEUTICS INC 摘要:Semi-synthetic glycopeptides having antibacterial activity are described, in particular, the semi-synthetic glycopeptides described herein are made by chemical modification of a glycopeptide (Compound A, Compound B, Compound H or Compound C) or monosaccharide made by hydrolyzing the disaccharide moiety of the amino acid-4 of the parent glycopeptide in acidic medium to give the amino acid-4 monosaccharide; conversion of the monosaccharide to the amino-sugar derivative; acylation of the amino substituent on the amino acid-4 amino-substituted sugar moiety on these scaffolds with certain acyl groups; and conversion of the acid moiety on the macrocyclic ring of these scaffolds to certain substituted amides. Key reaction is the treatment of properly protected intermediate compound with isocyanate. Also provided are methods for the synthesis of the compounds, pharmaceutical compositions containing the compounds, and methods of use of the compounds for the treatment and/or prophylaxis of diseases, especially bacterial infections.
专利号:US-6977141-B2 优先权日:1998-02-10 标 题 :Direct adsorption scintillation assay for measuring enzyme activity and assaying biochemical processes 发明人:YUAN ZHENGYU; CHEN ZHONG-XIAO 权利人:VICURON PHARM INC 摘要:Methods and materials for scintillation assays are disclosed. The scintillation assays rely on differences in general molecular property-based binding interactions, such as charge or hydrophobicity, to localize a radioactive substance near a scintillating material, stimulating scintillation. They are thus described as a direct adsorption scintillation assay (DASA) to distinguish them from the scintillation proximity assay (SPA). The assays are more convenient and inexpensive to implement than SPAs, which rely on specific binding of ligand-receptor pairs, antibody-antigen pairs, or other binding partners which rely on the precise and specific structural complementarity of the partners. The assays can be employed for studying enzymatic reactions, such as those involved in the synthesis of Mur-pentapeptide. The assays are readily adaptable to high throughput screening for use in conjunction with combinatorial libraries of compounds.

The chemical synthesis makes available a sustainable and substantially pure source of supply of lipid II, including analogs thereof, that may be used in the identification of new therapeutic agents capable of disrupting steps in bacterial cell wall biosynthesis.
专利号:US-10934326-B2 优先权日:2016-10-31 标 题:Peripheral modifications on pocket-redesigned vancomycin analogs synergistically improve antimicrobial potency and durability 发明人:BOGER DALE 权利人:SCRIPPS RESEARCH INST 摘要:A C-terminus modification to a binding pocket-modified vancomycin introduces a quaternary ammonium salt that provides a binding pocket-modified vancomycin analog with a second mechanism of action that is independent of D-Ala-D-Ala/D-Ala-D-Lac binding. The modification disrupts cell wall integrity and induces cell wall permeability complementary to the glycopeptide inhibition of cell wall synthesis, and provides synergistic improvements in antimicrobial potency (200-fold) against vancomycin-resistant bacteria. Combining the C-terminus and binding pocket modifications with an orthogonal (4-chlorobiphenyl) methyl addition to the vancomycin disaccharide provides even more potent antimicrobial agents whose activity can be attributed to three independent and synergistic mechanisms of action, only one of which requires D-Ala-D-Ala/D-Ala-D-Lac binding. The resulting modified vancomycins display little propensity for acquired resistance through serial exposure of vancomycin-resistant Enterococci and their durability against such challenges as well as their antimicrobial potency follow predicable trends. Methods of treatment with and compositions containing the modified vancomycins are disclosed.
