Description Bafilomycin A1 belongs to the macrolide class of antibiotics and is a V-ATPase (IC50=0.44 nM) that is specific and reversible. Bafilomycin A1 is an inhibitor of the late phase of autophagy, blocking the fusion of autophagosomes with lysosomes. Bafilomycin A1 also induces apoptosis.
In vitro METHODS: Human pancreatic cancer cells Capan-1 were treated with Bafilomycin A1 (1-100 nM) for 72 h. Cell growth inhibition was detected using MTT.
RESULTS: Bafilomycin A1 dose-dependently inhibited the growth of Capan-1 cells with an IC50 of 5 nM. [1]
METHODS: Human osteosarcoma cells MG63 were treated with Bafilomycin A1 (1 μmol/L) for 6-24 h. The expression levels of target proteins were detected by Western Blot.
RESULTS: Bafilomycin A1 induced a significant increase in the levels of apoptosis-related proteins p53 and Beclin 1, a significant decrease in the expression of autophagy-related proteins p62 and LC3-I, and an increase in LC3-II. [2]
METHODS: Human hepatocellular carcinoma cells BEL7402 and HepG2 were incubated with Bafilomycin A1 (5 nM) for 24 h, and the cell cycle was examined by Flow Cytometry.
RESULTS: Bafilomycin A1 increased the percentage of BEL7402 and HepG2 cells in the G1 phase of the cell cycle, while cells in the G2/M phase decreased, indicating G1 phase arrest. [3]
In vivo METHODS: To assay antitumor activity in vivo, Bafilomycin A1 (0.1-1 mg/kg) was intraperitoneally injected once daily for three days into NOD-SCID mice harboring the human acute lymphoblastic leukemia tumor B-ALL.
RESULTS: Bafilomycin A1 prolonged the survival and improved the pathology of xenograft mice by targeting leukemia cells. [4]
METHODS: To investigate the role of autophagy in chronic wound healing, Bafilomycin A1 (1 mg/kg) was administered as a single intraperitoneal injection to diabetic db/db mice.
RESULTS: Bafilomycin A1 treatment significantly accelerated wound healing in db/db mice and exerted a favorable healing effect.Bafilomycin A1 may accelerate the healing of diabetic chronic refractory wounds by promoting cell proliferation, collagen production, and modulating inflammatory homeostasis.

Molecular Weight Calculator

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
