Encapsulating propeller-like columnar liquid crystals with an aromatic outer shell: influence of phenoxy-terminated side chains on the phase behaviour of triphenylbenzenes
temperatures of columnar liquid crystals by side chain variation is often associated with an undesired change in the mesophase type and/or geometry. To overcome this problem phenoxy-terminated side chains rather than alkyl side chains were grafted onto triphenylbenzenes, which resulted in reduced clearing points, while melting points were little affected. More importantly, helicalcolumnarself-assembly was not
In screening experiments certain omega-substituted alkyl carboxylic acids were found to produce an increase in insulin-stimulated C-14-acetate incorporation into triglycerides, which may indicate an improvement in the action of insulin. Antidiabetic and lipid-lowering properties in genetically diabetic ob/ob mice demonstrated the in vivo relevance of the insulin-potentiating effects seen in vitro. The chemical structures of the w-substituted alkyl carboxylic acids with insulin-potentiating effects correspond to the general formula ring-spacer-COOH. A close structure-activity relationship was observed. The most potent compound in ob/ob mice was 3e, which normalized blood glucose as well as hyperinsulinaemia and lowered serum triglycerides and cholesterol by 52% and 37%, respectively. On the basis of these results, omega-substituted alkyl carboxylic acids are interesting as a new class of oral antidiabetic agents with insulin-sensitizing and lipid-lowering activity.
