Safety and Efficacy of Intermittent High-Dose Liposomal Amphotericin B Antifungal Prophylaxis in Haemato-Oncology: An Eight-Year Single-Centre Experience and Review of the Literature

open access: yesJournal of Fungi, 2020
Triazoles remain first-line agents for antifungal prophylaxis in high-risk haemato-oncology patients, but their use is increasingly contraindicated due to drug–drug interactions and additive toxicities with novel treatments. In this retrospective, single-

1,2,4-Triazoles. VII. Methylation of 1,2,4-triazoles.

open access: yesChemical and Pharmaceutical Bulletin, 1976
The methylations of twenty-five 1, 2, 4-triazoles with methyl iodide and diazomethane were studied and substituent effects on the product ratios are discussed. Methylation of 1, 2, 4-triazole and its symmetrically 3, 5-disubstituted derivatives occurred almost exclusively at the 1-position.
