Over the past two decades, the incidence of infections due to Candida glabrata, a yeast with intrinsic low susceptibility to azole antifungals, has increased markedly. Respiratory deficiency due to mutations in mitochondrial DNA (mtDNA) associated with resistance to azoles frequently occurs in vitro in this species. In order to specify the relationships between respiration and azole susceptibil...

The efficacy of FK463, a new (1,3)-beta-D-glucan synthase inhibitor, against azole-resistant Candida albicans strains has been studied. The MIC of FK463 was lower than those of azoles and amphotericin B against CDR1-expressing C26 and CaMDR-expressing C40 strains. All mice treated with FK463 (1 mg/kg) survived disseminated murine candidiasis. The fungal burden in the kidney after 6 days was mar...

Candida dubliniensis is a recently described species of pathogenic yeast that shares many phenotypic features with Candida albicans. It is primarily associated with oral colonization and infection in HIV-infected individuals. Isolates of C. dubliniensis are generally susceptible to commonly used azole antifungal agents; however, resistance has been observed in clinical isolates and can be induc...

There are currently a number of licensed azole antifungal drugs; however; only 4 (namely, fluconazole, itraconazole, posaconazole, and voriconazole) are used frequently in a clinical setting for prophylaxis or treatment of systemic fungal infections. In this article, we review the pharmacokinetic interactions of these azole antifungal drugs with other coadministered agents. We describe these (2...

Ferric chloride induced dehydrodimerization of l,2 ,3 ,4 -te trah yd ro-9 //-carb azole (1) gives pro­ duct 6 , the structure of which was established on the basis of its spectroscopic properties. The *H and 13C chemical shifts of the arom atic part of 1 , as well as of 4a-m eth yl-2 ,3 ,4 ,4a-tetrah yd ro-l Hcarbazole (7 a ) and 4a-ph enyl-2 ,3 ,4 ,4a-tetrahyd ro-l//-carb azole (7b ) have also...

The title compound, C(22)H(20)N(2), (Ib), forms along with 2-[(cyclo-penta-1,3-dien-1-yl)diphenyl-meth-yl]-1-methyl-1H-imid-azole, (Ia), which differs with respect to the position of the double-bonds in the C(5)H(5) ring, in an approximately 3:7 ratio (Ia:Ib; NMR spectroscopy data). However, in a single crystal, only compound (Ib) is present. H atoms of the CH(2) group (C(5)H(5) ring) were foun...
