522-53-2
Chemical Structure
Lobaric acid
- CAS No.: 522-53-2
- Formula:C25H28O8
- Molecular Weight:456.49
IUPAC Name: 8-hydroxy-3-methoxy-11-oxo-1-pentanoyl-6-pentyl-11H-dibenzo[b,e][1,4]dioxepine-7-carboxylic acid
InChIKey: JHEWMLHQNRHTQX-UHFFFAOYSA-N
SMILES: O=C(C1=C(O)C=C(C(OC2=CC(OC)=CC(C(CCCC)=O)=C23)=C1CCCCC)OC3=O)O
Biological Activity: Lobaric acid is a depsipeptide metabolite isolated from Stereocaulon lichen with antioxidant, antiproliferative, antiviral and enzyme inhibitory activities. Lobaric acid scavenges superoxide free radicals (IC50=97.9 μM) and inhibits cancer cell proliferation (EC50 of 15.2-63.9 μg/mL against leukemia, colorectal, gastric, breast, ovarian, prostate, pancreatic and lung cancer cell lines). Lobaric acid inhibits protein tyrosine phosphatase 1B (PTP1B; IC50=0.87 μM for human recombinant enzyme) and 12(S)-HETE produced by 12(S)-lipoxygenase (IC50=28.5 μM). Lobaric acid (250 μM) also reduced pathological changes in tobacco leaves infected with tobacco mosaic virus (TMV).
