摘要:
A method of effecting a cholesterol-level-decreasing effect in blood, and also pharmaceutical compositions, are both based on substituted flavanoids of the following formula, as well as their acid addition salts and quaternary ammonium derivatives: WHEREIN R1 and R2 are identical or different and can represent OH; alkoxy of one to 10 carbon atoms and if desired substituted by other moieties; tetrahydropyranyl-(2)-oxy; acyloxy of one to six carbon atoms; NO2; NH2; alkylated NH2 having one to eight carbon atoms; or acylamino of two to six carbon atoms; R3 can represent H; OH; alkyl and alkoxy of one to three carbon atoms; NH2; or Hal; R4 can represent O; H, OH; H, H; or N, NH2; R5 can represent H or R1; Hal can represent Cl; Br; or I; R2 and R5 together can also represent methylene dioxy; ethylene dioxy; or propylene dioxy; and wherein, in the 2,3-position, an additional double bond can be present.

THE FOLLOWING FLAVANE COMPOUNDS EXHIBIT A CHOLESTEROL-LEVEL-LOWERING ACTIVITY WITHOUT, HOWERE, EFFECTING A NONPHYSIOLOGICAL ACCUMULATION OF DEMOSTEROL OR 7-DEHYDROCHOLESTEROL IN THE STEROLS OF THE SERUM OR OF THE LIVER;
2-(C6H5-),3-R1,6-(R2-O-)CHROMAN
WHEREIN
R1 REPRESENTS ALKYL OR ALKOXY OF 1-6 CARBON ATOMS; R2 REPRESENTS HYDROGEN, ALKYL OF 1-6 CARBON ATOMS, OR AN ESTER, THE ACYL PORTION BEING UP TO 5 CARBON ATOMS.
