Tatanans were isolated from the rhizomes of Acorus tatarinowii Schott by De-Quan Yu and co-workers at the Chinese Academy of Medical Sciences and Peking Union Medical College.  These compounds were found to have antihyperglycemic activity with EC1.5 values ranging from 0.16−1.85 μM.

Eutypoids B-E

Posted by naturalproductman on December 6, 2010

Johannes Imhoff and co-workers at Leibniz-Institute of Marine Sciences have published in the Journal of Natural Products on the isolation of eutypoids B-E from the Penicillium sp. strain KF620 i.  Eutypoid B had an IC50 of 0.78 micromolar against glycogen synthase kinase-3β (GSK-3β), which is a target for treating type 2 diabetes and Alzheimer’s disease.

Duboscic acid

Posted by naturalproductman on November 22, 2010

Pascal Wafo and co-workers from France have published in Organic Letters on the isolation of duboscic acid.  It had alpha-glucosidase inhibition activity with with an IC50 value of 100 ± 8.1 μM.  So you might wonder why alpha-glucosidase inhibition is important – alpha-glucosidase is an enzyme that hydrolyzes disaccharides into monosaccharides so the inhibition of this enzyme should slow down the absorption of glucose in people, which is especially important in diabetic patients.

Grecocycline B

Posted by naturalproductman on March 20, 2010

Thomas Paululat and co-workers at the University of Siegen in Germany have recently reported on the isolation of grecocycline B from Streptomyces sp. Acta 1362.  The new polycyclic compound had an IC50 of 0.52 micromolar against tyrosine phosphatase B1.  Interestingly, protein tyrosine phosphatase PTP1B is a target for the treatment of obesity, type 2 diabetes and cancer.
