  Based on the fact that petroselinic acid showed good inhibitory activity (IC50 = 6.99 mu mol/L) against protein tyrosine phophatase 1B(PTP1B) in vitro, a series of novel N-(alkoxyphenyl)-aminocarbonylbenzoic acid derivatives were designed and synthesized. The results indicated that most of the derivatives showed more potent activities against PTP1B. Especially, compound 13 had obvious activity with an IC50 of 106 nmol/L in vitro. (C) 2010 Song Wu.

  A new group of compounds, C6H5-N(O)=N-NH-C6H4-C(O)-O-C6H4-CH=N-C6H4-OR, (1), [R=n-alkyl group; 1 alpha (R=C7H15) to 1h (R=C14H29)], has been designed and synthesized to develop triazene-1-oxide based liquid crystals. All the compounds have been characterized on the basis of their spectral data. Their thermal behavior has been examined and found to exhibit thermotropic liquid crystalline behavior over a wide range of temperature. All members of this family uniformly show nematic phase behavior on melting up to the clearing point during heating as well as on phase entering up to the solidification during cooling. An odd-even effect on transition temperatures has been observed during heating as well as cooling.

  With the objective to study the effect of alkoxy terminal chain length on mesomorphic properties of liquid crystals, we have synthesized two (Azo and Imine) different series of dimesogens by varying terminal alkoxy chain length (n=6-12) with a short spacer unit in between two mesogens. Transition temperatures and phase characterization were studied by DSC, POM and XRD analysis. It was found that all the dimers show mesomorphic properties and the change in terminal alkoxy chain length has pronounced effect on the smectic phase window. In the DSC cooling scan, the smectic phase window of azo compounds increased from 6.4 degrees C (2A(6)) to 16.0 degrees C(2A(12)), whereas in Schiff base compounds, it increased from 9.2 degrees C (2S(6)) to 31.0 degrees C(2S(12)). Further, the 2A(11) dimer was found to undergo photo induced configurational changes.
