Description
TRIANGULIC FLOWER AGENTS
MEMORIfi DESCRIPTIVE
This invention relates to triazole derivatives having antifungal activity and are useful in the treatment of fungal infections in animals, including humans. Therefore / this invention provides compounds of formula (I):
pharmaceutically acceptable salts thereof and pharmaceutically acceptable solvates of any entity, wherein: X is CH or N; R1 is phenyl substituted with 1 to 3 substituents, each independently selected d? halo and CF3; R 2 is hydroxyalkyl Ci -C ", CONH 2, S (0)» (Ci-C alkyl "), Ar or Het; m is 1 or 2; Rr is phenyl, optionally monosubstituted with halo or CF37 Het is a 6-membered nitrogenous aromatic heterocycle, attached to a C, containing 1 or 2 nitrogen atoms, or a 5-membered nitrogenous heterocyclic group, attached to a C or an N , which contains from 2 to 4 nitrogen atoms, wherein said heterocyclic groups are optionally substituted with C 1 -C 4 alkyl or with (C 1 -C 4 alkoxy) rnetyl. In the above definition, unless otherwise indicated, alkyl and alkoxy groups having three or more carbon atoms may be straight or branched chain; Halo means fluoro, chloro, bromo or iodo. In addition, Het is selected from pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl, pyrazolyl, imidazolyl, triazolyl or tetrazolyl. The compounds of formula (I) contain at least two chiral centers and, therefore, can exist as stereoisomers, that is, as enantiomers or diastereomers and as mixtures thereof. The invention includes the two individual stereoisomers of the compounds of formula (19 together with mixtures thereof) Separation of the diastereomers can be achieved by conventional techniques, for example, by fractional crystallization or chromatography [including high performance liquid chromatography (HPLC )] of a diastereomeric mixture of a compound of formula (19) or a salt or derivative thereof An individual enantiomer of a compound of formula (19) can also be prepared from a corresponding, optically pure intermediate, by HPLC resolution of the racemate using a suitable chiral support or by fractional crystallization of the diastereomeric salts formed by reaction of the racemate with a suitable optically active acid The preferred etheromers of formula (I) have the (2R, 3S) configuration of formula (IA):
In addition, the compounds of formula (I) can exist as cis- or trans-alkene isomers and the invention also includes the two separate individual isomers and mixtures thereof. The preferred isomers are the trans isomers. Certain compounds of formula (I) may also exist in tautomeric forms and the invention includes the two separate individual tautuses and mixtures thereof. Also included in the invention are radiolabeled derivatives of compounds of formula (I), which are suitable for biological studies. The pharmaceutically acceptable salts of the compounds of formula (I) are, for example, non-toxic salts, formed by the addition of inorganic acids, such as hydrochloric, hydrobromic, sulfuric and phosphoric acid, organic carboxylic acids or organic sulfonic acids.
Certain compounds of formula (I) can also provide pharmaceutically acceptable salts of a metal, in particular non-toxic alkali metal salts, with base. Examples include sodium and potassium salts. For an analysis of suitable pharmaceutical salts, see 3. Pharm. Sci., 1977, 5, 1.
