Pymetrazine is chosed as the lead compound, and 21 compounds were firstly designed and synthesized. These compounds were characterized by introducing phenyl derivatives with different functional groups to replace pyridine ring with the isosteric principle and the method of homogeneous synthesis and reasonable biologically designing in order to find new compounds with potential biological activity. These compounds were confirmed by IR, H NMR and MS spectra.

The effects of different of categories surfactants, the proportion of surfactant and cosurfactant , the chain lengths of alcohol and alkane, temperatures and pH values on the W/O microemulsion phase areas are systematically studied in the dissertation. SEM and laser scatting techniques are used to verify particles'sizes of W/O microemulsion. Consequently, a system TritonX-100/n-C〓H〓OH (weight ratio 1: 1)/C〓H〓/H〓O is obtained which is a stable system with relatively large W/O microemulsion phase area.
