标题:Method for synthesis of ciguatoxin CTX1B and compounds useful for the synthesis of ciguatoxin CTX1B
发明人：HIRAMA MASAHIRO; INOUE MASAYUKI
权利人:JAPAN SCIENCE & TECH AGENCY
摘要:Disclosed is a method for total synthesis of CTX1B, which is developed for the synthesis of a ciguatoxin analogue such as CTX3C and enables the more efficient application of an established reaction to the total synthesis of CTC1B. More specifically, disclosed is a method for total synthesis of CTX1B comprising; an O.S-acetal formation for synthesizing a novel compound (3); a radical cyclization reaction for constructing a 9-membered ring formation reaction including a novel compound (6) through a novel compound (8) and yielding a compound (D); and a deprotection for yielding CTX1B. Also disclosed are novel compounds (1) to (8) which are particularly useful for synthesis of CTX1B and can be used for the synthesis of a ciguatoxin analogue.

摘要:Disclosed are a novel method for the synthesis of a glycopeptide by which glycopeptides of various types can be deprotected and excised from a resin, each under weakly acidic to weakly basic conditions, without causing the problems of the epimerization of an amino acid at the a-position and the ß-elimination of a sugar residue; a synthesis device therefor; and a synthesis intermediate to be used in synthesizing a glycopeptide. Specifically disclosed are a method for the solid-phase synthesis of a glycopeptide which comprises a step for obtaining a glycopeptide derivative wherein the N-terminus is protected, the C-terminus is immobilized to a solid phase via a silicon linker, and a reactive group carried by a sugar residue and a reactive group carried by an amino acid side chain constituting a peptide are protected by silicon-containing groups, and a step for obtaining the glycopeptide by deprotecting said glycopeptide derivative and releasing the same from the solid phase by treating the glycopeptide derivative with an agent for removing the silicon-containing groups and the silicon linker; a synthesis intermediate to be used in the step for obtaining the glycopeptide derivative in the aforesaid method; and a device for the solid-phase synthesis of a glycopeptide.

摘要:The present invention provides a water soluble polymer surfactant (PS-DGlu) of formula I which is utilized for synthesis of functionalized polystyrene nanobead covalently incorporating (oligo) p-phenylenevinylene (OPV) nanosensor (PSG-OPV-n) which in turn is useful for the detection of bilirubin in human serum. The present invention further provides a process for the preparation of the water soluble polymer surfactant (PS-DGlu) of formula (I) and a mini emulsion polymerization process for the synthesis of PSG-OPV-n.wherein, n is 30-50.The PSG-OPV-n nanosensor beads show selectivity towards detection of bilirubin in presence of interferences such as glucose, sucrose, metal ions, cholesterol, and biliverdin with limit of detection of 20 nM. Ultimately, the invention also provides a kit for visual detection of bilirubin in human serum.
