2-Substituted 3-(aminooxy)propanamines as inhibitors of ornithine decarboxylase: synthesis and biological activity
摘要:
1-Amino-3-(aminooxy)-2-propanol (6a) has been synthesized and found to inhibit rat liver ornithine decarboxylase (ODC) with an IC50 in the nanomolar range. Compound 6a served as a basis for the design of new enzyme inhibitors, which led to the identification of 3-(aminooxy)-2-fluoropropanamine (15) as a new powerful enzyme blocker. Compound 15 inhibited ODC at 3 times lower concentrations than 6a and 3-(aminooxy)propanamine (APA), and it was superior to APA as an antiproliferative agent in inhibiting the growth of human T24 bladder carcinoma cells in vitro.

Trifluoromethylthiocopper has been found to catalyze the opening of the epoxide ring and to furnish not-so-easily accessible novel trifluoromethylthiolated α-hydroxy compounds. This communication presents the mechanism of the formation of the various compounds and their mass spectral data.
