Novel potential HIV protease inhibitors are obtained by an enantioconvergent synthesis of mimicking Phe-Pro dipeptides, achieved through the coupling between Boc(L)Phe or Boc(L)Tyr and both enantiomers of syn-2-benzylpyrrolidin-3-ol and their corresponding pyrrolidin-3-one analogs. The stereochemistry and enantiopurity of intermediate 3-hydroxypyrrolidines 5a and 5b are determined through 1H NMR analysis, and through the synthesis and 19F NMR assignments of the corresponding Mosher’s esters 13a and 13b. The enantiopure compounds 5a and 5b are obtained with 100% diastereoselectivity using specific experimental reductive conditions upon Meldrum’s acid derivatives of activated aromatic amino acids.
Most zinc metalloproteases are over-expressed in tumor cells and play a critical role in the genesis, development, and metastasis of tumors. Novel zinc binding groups (ZBGs) represent a novel strategy to obtain optimal potency and selectivity for zinc metalloproteases inhibitors. Here we described the design, synthesis, and biological studies of novel p-dicarbonyl derivatives as aminopeptidase N (APN/CD13) inhibitors. The results demonstrated that some compounds exhibited moderate to good inhibitory activities against APN with compound 5c being the most potent, suggesting that 5c could serve as new lead for the future APN inhibitor development. The results further confirm our design rationale of P-dicarbonyl moiety as a new ZBG, which may provide a new direction for the design and discovery of zinc metalloproteases inhibitors as new anti-tumor agents.
