The disclosure describes a pharmaceutical composition comprising an aromatase-inhibiting effective amount of a compound selected from the group consisting of compounds of the formula (I): ##STR1## including their stereoisomers and salts thereof, wherein R.sup.1 is halogen or phenyl; m is 0, 1, 2 or 3; k and n each are independently 0, 1 or 2; R.sup.2 and R.sup.3 each are independently H or OH; R.sup.6 and R.sup.7 each are independently H or C.sub.1-4 alkyl; R.sup.8 and R.sup.9 each are H or R.sup.8 and R.sup.9 form --C(R.sup.4) (R.sup.5)--C(R.sup.11) (R.sup.12)-- bond wherein R.sup.4, R.sup.5, R.sup.11 and R.sup.12 each are independently H or C.sub.1-4 alkyl; Y is N or CH; and R.sup.10 is H or halogen, or R.sup.10 combines with R.sup.2 to form --O-- bond, with proviso that if R.sup.8 and R.sup.9 form --C(R.sup.4) (R.sup.5)--C(R.sup.11) (R.sup.2)-- bond, R.sup.3, R.sup.6 and R.sup.7 each are H, and k and n each are 1, then R.sup.2 and R.sup.10 form --O-- bond, and a pharmaceutically acceptable carrier or diluent.

Aromatase-inhibiting composition containing azole derivative

A compound of the formula (I): ##STR1## wherein R.sup.1 and R.sup.2 are, independently, a hydrogen atom, a monosaccharide residue, a protected monosaccharide residue, or a protecting group for hydroxyl group, but at least one of R.sup.1 and R.sup.2 is a monosaccharide residue or a protected monosaccharide residue, and R.sup.3 is a hydrogen atom, a hydroxyl group, an alkyl group, an aryl group, or an aralkyl group, with the proviso that (1) when R.sup.1 and R.sup.2 are glucose residues at the same time, R.sup.3 is not a hydrogen atom, (2) when R.sup.1 is a hydrogen atom, an acetyl group or a benzyl group and R.sup.2 is a glucose residue, an acetylated glucose residue, or acetalized glucose residue, R.sup.3 is not a hydrogen atom, or (3) when R.sup.1 is a glucose residue and R.sup.2 is a hydrogen atom, R.sup.3 is not a hydrogen atom or a salt thereof is disclosed.

Esculetin derivatives and method for manufacture thereof, use thereof,

The disclosure describes a pharmaceutical composition comprising an aromatase-inhibiting effective amount of a compound selected from the group consisting of compounds of the formula (I): ##STR1## including their stereoisomers and salts thereof, wherein R.sup.1 is halogen or phenyl; m is 0, 1, 2 or 3; k and n each are independently 0, 1 or 2; R.sup.2 and R.sup.3 each are independently H or OH; R.sup.6 and R.sup.7 each are independently H or C.sub.1-4 alkyl; R.sup.8 and R.sup.9 each are H or R.sup.8 and R.sup.9 form --C(R.sup.4) (R.sup.5)--C(R.sup.11) (R12)-- bond wherein R.sup.4, R.sup.5, R.sup.11 and R.sup.12 each are independently H or C.sub.1-4 alkyl; Y is N or CH; and R.sup.10 is H or halogen, or R.sup.10 combines with R.sup.2 to form --O-- bond, with proviso that if R.sup.8 and R.sup.9 form --C (R.sup.4) (R.sup.5)--C(R.sup.11) (R.sup.12)-- bond R.sup.3, R.sup.6 and R.sup.7 each are H, and k and n each are 1, then R.sup.2 and R.sup.10 form --O-- bond, and a pharmaceutically acceptable carrier or diluent.

This invention provides a method of inhibiting aromatase and treating of estrogen-dependent diseases in a patient by administering azole derivatives as nonsteroidal inhibitors. The azole derivative has the formula ##STR1## where R.sub.1 a is hydrogen or a (C.sub.1 -C.sub.5) alkyl; R.sub.2 is a hydrogen or a (C.sub.1 -C.sub.5) alkyl; R.sub.3 is any of a halogen, a (C.sub.1 -C.sub.5)alkyl, a haloalkyl, a phenyl, a cyano, or nitro; n is 0 to 5; and Y is a nitrogen atom or CH.
