The in vitro and in vivo activities of a series of (2R, 3R)-2-(2,4-difluorophenyl)-3-(substituted indazol-1-yl)-1-(1H-1,2,4-triazol-1-yl)butan-2-ol as potential antifungal agents are described. In particular, the analog 12j having 5-bromo substitution on the indazole ring exhibited significant antifungal activity against a variety of fungal cultures (Candida spp. and Aspergillus spp.). In addition, oral administration of 12j showed its excellent efficacy against Candida albicans in a murine infection model and the significantly improved survival rates of the infected mice.

- Tricyclic indole-2-carboxylic acids: Highly in vivo active and selective antagonists for the glycine binding site of the NMDA receptor
-
A series of tricyclic indole-2-carboxylic acid derivatives were synthesized and evaluated by the radioligand binding assay and the anticonvulsant effects in the mouse NMDA-induced seizure model. Among them, derivatives of 3S-(-)-4 such as 3a, 3f, and 3g which had certain zwitterionic anilides showed high affinity to the NMDA-glycine binding site. The absolute configuration of 3S-(-)-4 was confirmed by X-ray crystallographic analysis. In particular, 3g (SM-31900) was found to be a highly active glycine antagonist for both in vitro and in vivo assays (Ki = 1.0 ± 0.1 nM, ED50 = 2.3 mg/kg, iv) and also showed high selectivity for the glycine site. In addition, 3g was soluble enough in aqueous media (> 10 mg/mL at pH 7.4) to use for medications by intravenous injection.

- Optically active antifungal azoles. I. Synthesis and antifungal activity of (2R,3R)-2-(2,4-difluorophenyl)-3-mercapto-1-(1H-1,2,4-triazol-1-yl)-2- butanol and its stereoisomers
-
(2R,3R)-2-(2,4-Difluorophenyl)-3-mercapto-1-(1H-1,2,4-triazol-1-yl)-2- butanol [(2R,3R)-7] and its stereoisomers [(2S,3R)-, (2S,3S)- and (2R,3S)-7] were prepared from the optically active oxiranes 6 by a newly developed ring- opening reaction and evaluated for antifungal activity. The thiol (2R,3R)-7 showed extremely potent antifungal activity in vitro and in vivo. The optically active oxirane (2R,3S)-6, a useful intermediate for the synthesis of sulfur-containing antifungal azoles 5, was synthesized from methyl (R)- lactate [(R)-8] via eight steps in a stereocontrolled manner. The key step in the synthesis is the Grignard reaction of an amide derivative [(R)-12a] of (R)-lactic acid with 2,4-difluorophenyl-magnesium bromide (13).
