Two series of thiophene oligomers and terthiophene oligomers consisting of both thiophene and indole moieties have been synthesized. They have same excitation-dependent photoluminescence characteristics, but different bandgaps and absorption behaviors, which relates to the number and denseness of indoles in the conjugated oligomers and the length of alkyl chains on indole moiety due to varied the π-π

Members of a series of 2,4,5-substituted pyrimidine derivatives were synthesized, and their interactions with tubulin and their antiproliferative activities against the human hepatocellular carcinoma cells of liver (BEL-7402) were evaluated. One member of this family, the indole-pyrimidine 4k, having an indole-aryl-substituted aminopyrimidine structure, was observed to be an excellent inhibitor of tubulin polymerization (IC50 = 0.79 mu M) and to display significantly high antiproliferative activities against several cancer cell lines with IC50 values ranging from 16 to 62 nM. This substance displayed a high propensity to arrests cells at the G(2)/M phase of the cell cycle (EC50 = 20 nM). In addition, 4k was found to competitively inhibit colchicine binding to tubulin, indicating that it binds to the colchicine-binding site of tubulin. The observations made in this investigation demonstrate that 2,4,5-substituted pyrimidines represent a new class of tubulin polymerization inhibitors with significant antiproliferative activity.
