Antihyperglycemic activity of novel naphthalenylmethyl-3H-1,2,3,5-oxathiadiazole 2-oxides
摘要:
A series of naphthalenyl 3H-1,2,3,5-oxathiadiazole 2-oxides was prepared and tested for antihyperglycemic activity in the db/db mouse, a model for type 2 (non-insulin dependent) diabetes mellitus. Substitution at the 1-, 5-, or 8-positions of the naphthalene ring with a halogen was found to be beneficial to antihyperglycemic activity. 4-[(5-Chloronaphthalen-2-yl)methyl]-3H-1,2,3,5-oxathiadiazole 2-oxide (45), one of the most potent compounds in this series, was selected for further pharmacological evaluation.

What a bind! The CYP101B1 enzyme from the bacteria N. aromaticivorans has been engineered to better bind and oxidise hydrophobic aromaticsubstrates. His85 was identified by sequence alignment as a potential active-site residue. The H85F variant improved activity and offered unusual selectivity options.

The ruthenium(II)-catalyzed tandem C–H allylation and intramolecular dipolar cycloaddition between azomethine imines and 2-methylidenetrimethylene carbonate is described herein. The initially formed β-substituted allyl fragment could trigger the exotype [3 + 2] cycloaddition with the polar azomethine group, resulting in the formation of bridged tetracycles bearing a hydroxymethylene group at a bridgehead
