Pricing Availability Delivery Time Qty
Cat.No. 4039 - PT 1 | C23H16ClN3O6S | CAS No. 331002-70-1
Description: AMPK activator
Chemical Name: 2-Chloro-5-[[5-[[5-(4,5-Dimethyl-2-nitrophenyl)-2-furanyl]methylene]-4,5-dihydro-4-oxo-2-thiazolyl]amino]benzoic acid
Purity: ≥98% (HPLC)

Biological Activity

AMP-activated protein kinase (AMPK) activator. Stimulates AMPK heterotrimer (α1β1γ1) activity (EC50 = 0.3 μM). Selectively increases the activity of γ1- but not γ3-containing complexes. Thought to directly activate AMPK by antagonizing autoinhibition.

Preparing Stock Solutions

The following data is based on the product molecular weight 497.91. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.01 mL 10.04 mL 20.08 mL
5 mM 0.4 mL 2.01 mL 4.02 mL
10 mM 0.2 mL 1 mL 2.01 mL
50 mM 0.04 mL 0.2 mL 0.4 mL
