  • Germanium is present in all living plant and animal matter in micro-trace quantities. Clinical trials and use in private practices for more than a decade have demonstrated germanium's efficacy in treating a wide range of serious afflications. including cancer, arthritis and senile osteoporosis. To investigate anti-inflammatory activity of organic germanium, we measured the effect of organic germanium on histamine release, (omitted)

  • To investigate the relationship between structure and biological activity of phenylpropanoids, we measured effects of phenylpropanoids on anti-oxidant and whitening activity. In DPPH radical scavenging activity, caffeic acid analogues had anti-oxidant activity in a dose-dependent manner. Although phenylpropanoids did not inhibit purified tyrosinase activity, they significantly inhibited tyrosinase activity and melanin production in MSH-stimulated B16 melanoma cells. (omitted)

  • 2-Phenyl-1, 8-naphthyridin-4-ones had been synthesized for their cytotoxic activity. Substituted acetophenone was treated with NaH and diethyl carbonate to give ethyl benzoylacetates, which was reacted with substituted 2-aminopyridine and PPA to yield 2-phenylpyridopyrimidine-4-ones. These compounds was heated at $350^\times$C in liquid paraffin to afford final compounds, 2-phenyl-1 , 8-naphthyridin-4-ones.
