  Synthesis of imifuramine and its stereoisomers exhibiting histamine H3-agonistic activity

  摘要：

  The four possible stereoisomers of a novel imidazole C-nucleoside derivative were synthesized by the efficient use of a PhSe group. Among them, (+)-4(5)-[(2R,5R)-5-(aminomethyl)tetrahydrofuran-2-yl]imidazole (imifuramine) was indicated as a novel type of histamine H-3-agonist by a brain microdialysis method.

  Monoacylglycosylglycerols show anti-tumor promoting effects: in order to study the role of the ester function we have prepared by simple methods (R)-1-O-benzyl-1,2-decandiolk (R)-3-O-benzyl-1-O-hexyl-su-glycerol, and (R)-1-O-benzyl-5-oxo-1,2-decandiol; these optically active compounds are building blocks for the synthesis of monohexanoylglycosylglycerol isosters.

  Special delivery: Liposomal drug‐delivery systems in which prodrugs are activated specifically by disease‐associated enzymes have great potential for the treatment of severe diseases, such as cancer. A new type of phospholipid‐based prodrug has the ability to form stable small unilamellar vesicles (see picture). Activation of the prodrug vesicles by the enzyme sPLA2 initiates a cyclization reaction

  特殊递送：脂质体药物递送系统中的前药被疾病相关的酶特异性激活，在治疗严重疾病（如癌症）方面具有巨大潜力。一种新型的磷脂基前药具有形成稳定的单层小囊泡的能力（见图）。sPLA 2酶激活前药囊泡会引发环化反应，从而导致药物释放。

  amino acids including a rare 4,5-dihydroxy-2,3,4,5-tetrahydropyridazine-3-carboxylic acid, a γ-halogenated piperazic acid, and a novel δ-methylated piperazic acid in svetamycins B–C, E, and G. Moreover, isotope-labeled substrate feeding experiments demonstrated ornithine as the precursor of piperazic acid and that methylation at the δ position of the piperazyl scaffold is S-adenosyl-l-methionine (SAM)-dependent
