| Description | Bafilomycin A1 isa selective and reversible inhibitor of vacuolar H+ ATPases (V-ATPases) with IC50 value of 4-400 nM. | |||||
| Targets | V-ATPases | |||||
| IC50 | 4-400 nM | |||||
| Cell experiment [1]: | |
Cell lines | HeLa cells |
Preparation method | The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
Reacting condition | 0 ~ 20 nM |
Applications | Bafilomycin A1 dose-dependently inhibited the vacuolization of Hela cells induced by H. pylori, showing a 50% effect at 4 nM and a complete inhibition at 12.5 nM. In addition, Bafilomycin A1 also efficiently restored vacuolated cells to a normal appearance. |
| Animal experiment [2]: | |
Animal models | Young freshwater tilapias |
Dosage form | 0 ~ 10-5 mol/L; 30 mins |
Applications | In young tilapias, Bafilomycin A1 dose-dependently inhibited the rate of Na+ uptake with a Ki value of 1.6 × 10-7 mol/L. The inhibitory effect (20%) was observed at a concentration as low as 10-8 mol/L and increased linearly up to a concentration of 10-6 mol/L, after which it remained at approximately 90 % inhibition. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Bafilomycin A1 is a selective inhibitor of vacuolar H+ ATPases (V-ATPases) with I50 values of 4-400 nmol/mg 1.
Bafilomycin A1 was treated to different types of membrane ATPases with the dependent I50 of 400 nmol/mg, 4 nmol/mg and 50 nmol/mg for the vacuolar ATPases of a fungus (N. crassa), a plant (Z. mays), and an animal (bovine abrenal medulla). In addition, the inhibitory effect of bafilomycin A1 on vacuolar ATPases was further determined by testing its influence on H+-pumping activity. H+ translocation was completely inhibited by 10 nM bafilomycin A1 1. Other study has shown that bafilomycin A1 strongly inhibited the pit-forming activity of osteoclasts. The subcellular localization of V-ATPase in osteoclasts was been treated with or without bafilomycin A1 by immunoelectron microscopy. These results suggested that disruption of V-ATPase localization to the ruffled border by bafilomycin A1 resulted in the lack of acidification of the dentine surface 2.
Notes: I50 values is umol of bafilomycin AI per mg of protein giving 50% inhibition of ATPase activity.
