A panel of 637 isolates of Candida albicans that had been typed by multilocus sequence typing (MLST) and tested for susceptibility to amphotericin B, caspofungin, fluconazole, flucytosine, itraconazole, ketoconazole, miconazole, terbinafine and voriconazole was the material for a statistical analysis of possible associations between antifungal susceptibility and other properties. For terbinafine and flucytosine, the greatest proportion of low-susceptibility isolates, judged by two resistance breakpoints, was found in MLST clade 1 and among isolates homozygous at the MAT locus, although only three isolates showed cross-resistance to the two agents. Most instances of low susceptibility to azoles, flucytosine and terbinafine were among oropharyngeal isolates from HIV-positive individuals. Statistically significant correlations were found between terbinafine and azole minimal inhibitory concentrations (MICs), while correlations between flucytosine MICs and azole MICs were less strong. It is concluded that a common regulatory mechanism may operate to generate resistance to the two classes of agent that inhibit ergosterol biosynthesis, terbinafine and the azoles, but that flucytosine resistance, although still commonly associated with MAT homozygosity, is differently regulated. 相似文献

Sporotrichosis Successfully Treated with Terbinafine and Potassium Iodide: Case Report and Review of the Literature 总被引:1,自引:0,他引:1
Sporotrichosis is rare in Turkey. We report a 40-year-old woman who had subcutaneous sporotrichosis caused by sporothrix schenckii that was successfully treated with terbinafine (250 mg, twice a day) for a period of 6 months. She received a saturated solution of potassium iodide orally for two months. Terbinafine and potassium iodide are suggested to be the agents of choice for treatment of subcutaneous sporotrichosis. 相似文献

Selection of excipients used is a critical step in the design of a pharmaceutical dosage form as it affects its behavior upon application, as during storage. The purpose of the present study is to evaluate and compare the behavior of six liposomal formulations intended for topical application composed of two widely used phospholipids 1,2-diacyl-sn-glycero-3-phosphocholine and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine with and without incorporation of cholesterol. Liposomal hydrogels made of hydroxyethylcellulose 3% and incorporating the anti-fungal agent terbinafine hydrochloride (E)-N-(6,6-dimethyl-2-hepten-4-inyl)-N-methyl-1-naphthalene-methanamine (-hydrochloride) were prepared, their viscosity was measured and in vitro drug release was studied. Moreover, physical stability and drug retention during storage at two different temperatures (2–8?°C and RT) were examined over time. The results showed differences in the behavior between the two phospholipids while incorporation of cholesterol at the studied concentrations was found to be of minor importance. Drug release was found to be favorable from 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) liposomal hydrogels and drug retention was found to be higher at lower storage temperature for all batches. Original physicochemical properties of all batches were found to be retained at least for a week. 相似文献

Previously, we demonstrated that the extracellular signal‐regulated kinase (ERK)‐mediated pathway contributes to the terbinafine (TB)‐induced increases of p21 and p53 protein level as well as decrease of DNA synthesis in human umbilical venous endothelial cells (HUVEC). The aim of this study is to examine the involvement of c‐Jun NH2‐terminal kinase (JNK) in the TB‐induced increase of p21 protein level and DNA synthesis inhibition. Western blot analysis and kinase assay demonstrated that TB treatment increased both the protein level and the kinase activity of JNK1/2 in HUVEC. Transfection of HUVEC with JNK1 dominant negative (DN‐JNK1) prevented the TB‐induced increases of p21 and p53 protein level and decrease of DNA synthesis, suggesting that JNK1/2 activation is involved in the TB‐induced cell cycle arrest in HUVEC. Moreover, over‐expression of mitogen‐activated protein kinase (MEK)‐1 prevented the TB‐induced increase of JNK1/2 protein levels, suggesting that MEK‐1 is an upstream inhibitor of JNK. Transfection of HUVEC with DN‐JNK1 prevented the TB‐induced inhibition of ERK phosphorylation, suggesting that JNK1/2 might serve as a negative regulator of ERK. Taken together, our results suggest that JNK activation is involved in the TB‐induced inhibition of ERK phosphorylation, p53 and p21 up‐regulation and DNA synthesis inhibition in HUVEC. J. Cell.
