  Design and regioselective synthesis of a new generation of targeted therapeutics. Part 3: Folate conjugates of aminopterin hydrazide for the treatment of inflammation

  摘要：

  Efficient syntheses of folate receptor (FR) targeting conjugates of the anti-inflammatory, aminopterin hydrazide, are described. 2-{4-Benzoylamino}-5-oxo-5-{N`-[2-(pyridin-2-yldisulfanyl)-ethoxycarbonyl]-hydrazino}-pentanoic acid is synthesized from commercially available 4-[(2-amino-4-imino-3,4-dihydro-pteridin-6-yl-methyl)-amino]-benzoic acid. Conjugation of this novel, activated aminopterin hydrazide to folic acid through cysteine-terminating (C-terminus), peptide/carbohydrate spacers results in highly water soluble conjugates which allow for the release of free aminopterin hydrazide within the endosomes of targeted cells.
