The vacuolar H+-ATPase (V-ATPase) was proposed as a key target for new strategies in cancer treatment recently. We have synthesized a novel class of derivatives of Cleistanthin-A bearing heterocyclic moieties. Most of these compounds displayed potent antiproliferative effects on four cancer cells at submicromolar concentration, and they have no cytotoxicity on normal WRL-68 cells at 200 nM. The most potent compound 3a has been shown to inhibit the activity of vacuolar H+-ATPase at submicromolar concentration, and it could also significantly decrease the cytosolic pH values in HepG2 cells. The current findings provide valuable insights for future development of novel V-ATPase inhibitors as anticancer agents. (C) 2015 Elsevier Ltd. All rights reserved.
