  Synthesis and Evaluation of Effective Inhibitors of Plant δ¹-Pyrroline-5-carboxylate Reductase

  摘要：

  Analogues of previously studied phenyl-substituted aminomethylene-bisphosphonic acids were synthesized and evaluated as inhibitors of Arabidopsis thaliana delta(1)-pyrroline-5-carboxylate reductase. With the aim of improving their effectiveness, two main modifications were introduced into the inhibitory scaffold: the aminomethylenebisphosphonic moiety was replaced with a hydroxymethylenebisphosphonic group, and the length of the molecule was increased by replacing the methylene linker with an ethylidene chain. In addition, chlorine atoms in the phenyl ring were replaced with various other substituents. Most of the studied derivatives showed activity in the rnicromolar to millimolar range, with two of them being more effective than the lead compound, with concentrations inhibiting 50% of enzyme activity as low as 50 mu M. Experimental evidence supporting the ability of these inhibitors to interfere with proline synthesis in vivo is also shown.
