Development of Synthetic Aminopeptidase N/CD13 Inhibitors to Overcome Cancer Metastasis and Angiogenesis
摘要:
Cancer metastasis is a major barrier to its treatment and an important cause of patient death. Antimetastatic agents hold promise for patients with advanced metastatic tumors. Aminopeptidase N/CD13 (APN) is being pursued by many as an important target against cancer metastasis and angiogenesis, but there are few reports on the in vivo evaluation of synthetic APN inhibitors. Herein, a series of compounds targeting APN were synthesized and evaluated for their antimetastasis and antiangiogenesis potency both in vitro and in vivo. Excitingly, compounds 4m, 4t, and 4cc, with the most potent APN inhibitory activities, displayed significant antimetastasis and antiangiogenesis effects in vitro and in vivo, suggesting that those synthetic APN inhibitors have the potential to overcome cancer metastasis and angiogenesis.

An efficient procedure has been developed for the synthesis of new chiral cholic acid molecular tweezer artificial receptors by linking an unsymmetrically disubstituted urea to methyl deoxycholate via a carbonate chain using microwave irradiation. The structures of these new receptors were confirmed by 1H NMR, IR, MS spectra and elemental analysis. Their binding properties were examined by UV-Vis spectra
