Apexbio Technology LLC Thonzonium Bromide,50mg CAS# 553-08-2

Thonzonium Bromide is a surface active agent and an inhibitor of V-ATPase proton transport with EC50 value of 69 µM [1] [2].Vacuolar ATPases (V-ATPases) are proton pumps that maintain pH homeostasis. V-ATPases couple the energy of ATP hydrolysis to proton transport across intracellular membranes [2].Thonzonium Bromide is a surface active agent and an inhibitor of V-ATPase proton transport. In wild-type yeast cells, thonzonium bromide significantly decreased the cytosolic pH to 6.22. In vacuolar membrane vesicles, thonzonium bromide inhibited proton transport with EC50 value of 69 µM in a dose-dependent way. However, thonzonium bromide didn’t inhibit ATP hydrolysis, which suggested that thonzonium bromide uncoupled V-ATPase proton pumps. In wild-type yeast cells, thonzonium bromide (1 µM) didn’t inhibit cell growth. Other sizes are also available. Please inqury us for quote.
