Abstract:
2-aryl-4-quinolones are converted into phosphates by reacting with tetrabenzyl pyrophosphate to form dibenzyl phosphates thereof, which are then subject to hydrogenation to replace dibenzyl groups with H, followed by reacting with Amberlite IR-120 (Na+ form) to form disodium salts. The results of preliminary screening revealed that these phosphates showed significant anti-cancer activity. A novel intermediate, 2-selenophene 4-quinolone and Λ/, Λ/-dialkylaminoalkyl derivatives of 2-phenyl-4-quinolones are also synthesized. These novel intermediates exhibited significant anticancer activities.

Abstract:
A method of treating a patient suffering a disease associated with Trichophyton mentagrophytes or Pityrosporum ovale by applying topically an anti-fungal pharmaceutical composition which is prepared from Zingiber officinale, includes the following steps: preparing a crude liquid from rhizomes of ginger by extraction with an organic solvent or supercritical CO2, or by distillation with steam; introducing the crude liquid to a reverse phase chromatography column, and eluting the column with water, a first eluent and a second eluent having a polarity weaker than that of the first eluent but stronger than that of chloroform, so that a first eluate resulting from elution of the first eluent and a second eluate resulting from elution of the second eluent are obtained; removing the first eluent and the second eluent from the first eluate and the second eluate by evaporation, respectively, so that a first concentrated eluate and a second concentrated eluate are obtained as the potent extract.
