title: Novel aminopeptidase N (APN/CD13) inhibitors derived from 3-phenylalanyl-N'-substituted-2,6-piperidinedione.
abstract: Aminopeptidase N (APN/CD13) over expressed on tumor cells, plays a critical role in tumor invasion, metastasis, and tumor angiogenesis. Here we described the design, synthesis and preliminary activity studies of novel APN inhibitors with 3-phenylalanyl-N'-substituted-2,6-piperidinedione scaffold. The results showed that compound 7c had the most potent inhibitory activity against APN with the IC(50) value to 5.00 +/-3.17 microM, which could be used as the lead compound in the future for anticancer agent research.
