6,7-Bis(arylthio)-quinazoline-5,8-dione and furo[2,3-f]quinazolin-5-ol derivatives were synthesized and tested for in vitro antifungal activity against Candida, Aspergillus species, and Cryptococcus neoformans. Among them tested, many of furo[2,3-f]quinazolin-5-ols and 6,7-bis(arylthio)-quinazoline-5,8-diones showed good antifungal activity. The compounds completely inhibited the growth of all

Cuban Cryptococcus isolates (n = 165) were tested in vitro against amphotericin B, flucytosine, fluconazole, itraconazole, voriconazole, posaconazole, and isavuconazole, giving MIC90 values of 0.25, 8, 4, 0.25, 0.125, 0.016, and 0.016 microg/ml, respectively. Isavuconazole and posaconazole seem to be

We report the first case, to our knowledge, of Blastoschizomyces capitatus infection occurring in a patient receiving empirical echinocandin therapy for neutropenic fevers. Clinicians should consider B. capitatus infection in those neutropenic patients who remain febrile despite echinocandin therapy or

Furo[2,3-f]quinolin-5-ol derivatives were synthesized and tested for in vitro antifungal activity against Candida,Aspergillus species, and Cryptococcus neoformans. Among them tested, many furo[2,3-f]quinolin-5-ols showed good antifungal activity. The results suggest that furo[2,3-f]quinolin-5-ols would be promising antifungal agents.

An efficient synthetic route to biologically relevant (-)-5-fluorocarbodine 6 was developed. Direct coupling of N(6)-protected 5-fluorouracil 15 with cyclopentenyl intermediate 13, followed by formation of a macrocycle between the base and the carbocyclic sugar moiety, via ring-closing metathesis, allowed for

Flucytosine (5-FC) is a synthetic antimycotic compound, first synthesized in 1957. It has no intrinsic antifungal capacity, but after it has been taken up by susceptible fungal cells, it is converted into 5-fluorouracil (5-FU), which is further converted to metabolites

A drug intended for use in humans should have an ideal balance of pharmacokinetics and safety, as well as potency and selectivity. Unfavorable pharmacokinetics can negatively affect the clinical development of many otherwise promising drug candidates. A variety of in

Effective treatment modalities for advanced melanoma are desperately needed. An innovative approach is virotherapy, in which viruses are engineered to infect cancer cells, resulting in tumor cell lysis and an amplification effect by viral replication and spread. Ideally, tumor selectivity

The antifungal flucytosine (5-fluorocytosine [5FC]) is a prodrug metabolized to its toxic form, 5-fluorouracil (5FU), only by organisms expressing cytosine deaminase. One such organism is Candida glabrata, which has emerged as the second most common agent of bloodstream and mucosal

As glioblastomas are mostly localized infiltrative lesions, gene therapy based on the retroviral replicating vector (RRV) system is considered an attractive strategy. Combinations of multiple suicide genes can circumvent the limitations associated with each gene, achieving direct and synergistic cytotoxic

In terms of genetically determined susceptibility to the clinical antifungal agent 5-fluorocytosine (5-FC), Candida albicans may be homozygous sensitive (FCY/FCY), homozygous resistant (fcy/fcy), or heterozygous (fcy/FCY). Although heterozygotes are only slightly resistant, they occur at significant frequency among clinical strains

Inactivation of the FCY2 (cytosine permease), FCY1 (cytosine deaminase), and FUR1 (uracil phosphoribosyltransferase) genes in Candida lusitaniae produced two patterns of resistance to flucytosine. Mutant fur1 demonstrated resistance to 5-fluorouracil, whereas mutants fcy1 and fcy2 demonstrated fluconazole resistance in the

We describe the prevalences and susceptibility profiles of two recently described species, Candida metapsilosis and Candida orthopsilosis, related to Candida parapsilosis in candidemia. The prevalences of these species (1.7% for C. metapsilosis and 1.4% for C. orthopsilosis) are significant. Differences

We evaluated the in vitro susceptibilities of 217 zygomycetes to amphotericin B, ketoconazole, fluconazole, itraconazole, voriconazole, posaconazole, caspofungin, and flucytosine. The significant in vitro activity of posaconazole against several species appears to support its reported clinical efficacy. Decreased susceptibility to
