Antifungal agents based on amides containing a phenyl group

A compound having the formula

• wherein:
• Z.sub.2 is OW.sub.2 wherein W.sub.2 is a hydrogen atom, a lower alkyl radical or an alkali metal or alkaline earth metal atom;
• R.sub.23 is methoxy and R.sub.24 is methoxy, or R.sub.23 and R.sub.24 together form a methylenedioxy or ethylenedioxy group, the carbon atoms of which are optionally substituted by lower alkyl or halogen:
• R.sub.25 represents:
• a hydrogen or halogen atom;
• an amino group which is optionally substituted by one or two lower alkyl groups;
• a lower alkyl, lower alkoxy, (lower)alkoxy-(lower)alkyl or lower alkylthio group, each of which is optionally halogenated or hydroxylated;
• R.sub.26 and R.sub.27, which are identical or different, each represent:
• hydrogen or halogen, at least one of R.sub.26 and R.sub.27 being other than hydrogen;
• cyano, nitro, thiocyanato, hydroxyl or carboxyl;
• alkyl, cycloalkyl, alkenyl, alkynyl, alkyl-S(O).sub.n (wherein n is 0, 1 or 2), alkoxy, cycloalkoxy, alkenyloxy or alkynyloxy, each of which has up to 8 carbon atoms and is optionally substituted by one or more halogen atoms;
• (lower)alkoxy-carbonyl, CO--NR'R", NR'R", N(R')--OC--R", O--CO--R' or O--CO--NR'R";
• or
• phenyl, naphthyl, phenyl-S(O).sub.n (wherein n is 0, 1 or 2), phenoxy, phenyl-(lower)alkyl, phenyl-(lower)alkyl-S(O).sub.n (wherein n is 0, 1 or 2), phenyl-(lower)alkoxy or thienyl, the phenyl or thienyl rings being unsubstituted or substituted by:
• halogen;
• nitro, cyano, carboxyl, hydroxyl, mercapto, thiocyanato, (lower)alkoxy-carbonyl, --CO--NR'R", --NR'R", --N(R')--CO--R", --O--CO--R' or --O--CO--NR'R";
• or
• lower alkyl, lower alkoxy, (lower)alkyl-S(O).sub.n (wherein n is 0, 1 or 2), cycloalkyl having 3 to 7 carbon atoms, phenyl, phenoxy, phenyl-S(O).sub.n (wherein n is 0, 1 or 2), phenylalkyl, phenylalkoxy or phenylalkyl-S(O).sub.n (wherein n is 0, 1 or 2), which is optionally halogenated and has 1 to 4 carbon atoms in the alkyl portion;
• R' and R", which are identical or different, each represent hydrogen;
• lower alkyl;
• cycloalkyl having 3 to 7 carbon atoms;
• optionally halogenated phenyl;
• optionally halogenated phenyl-(lower)alkyl;
• alkenyl or alkynyl having 3 to 7 carbon atoms;
• or alkoxyalkyl having 3 to 8 carbon atoms;
• and
• R.sub.28 and R.sub.29, which are identical or different, each represent hydrogen or halogen;
• hydroxyl;
• lower alkyl;
• lower alkoxy;
• (lower)alkoxy-(lower)alkyl;
• or (lower)alkoxycarbonyl;
• with the proviso that when R.sub.28 represents hydroxyl and R.sub.26 represents methyl, then W.sub.2 is other than hydrogen.
