Phaeosphaeriaceae is a family in the order Pleosporales containing numerous plant pathogens, endophytes, lichenised fungi, and environmental saprobes. A novel genus, Tintelnotia is introduced containing two species, one of which caused an eye infection and several nail infections in humans. All species of Tintelnotia produce conidia in soft pycnidia with a wide ostiole. The generic type species is T. opuntiae causing necrotic spots on cactus plants. The isolates of the human opportunist T. destructans showed variable susceptibility pattern to a panel of common antifungal agents...

In the context of the dangerous phenomenon of fungal resistance to the available therapies, we present here the chemical synthesis of a new series of thiazolyl-triazole Schiff bases B1-B15, which were in vitro assessed for their anti-Candida potential. Compound B10 was found to be more potent against Candida spp. when compared with the reference drugs Fluconazole and Ketoconazole. A docking study of the newly synthesized Schiff bases was performed, and results showed good binding affinity in the active site of co-crystallized Itraconazole-lanosterol 14α-demethylase isolated from Saccharomyces cerevisiae...

Four antimycotic drugs (tioconazole, TCZ; sertaconazole, STZ; fenticonazole, FTZ and itraconazole, ITZ) and the fungicide imazalil (IMZ) are determined in sludge from sewage treatment plants (STPs) following a bottom-up analytical strategy. First, sludge extracts, obtained under different sample preparation conditions, were analyzed by liquid chromatography (LC) quadrupole time-of-flight (QTOF) mass spectrometry (MS). A non-target search strategy, combined with the use of the chlorine mass filter, permitted to detect several chlorinated pollutants including the above referred azoles, which either had not been previously reported (TCZ, STZ, FTZ and ITZ), or scarcely investigated (IMZ), in this environmental compartment...

BACKGROUND: Triazole antifungals are essential to the treatment and prophylaxis of fungal infections. Significant pharmacokinetic variability combined with a clinical need for faster turnaround times has increased demand for in-house therapeutic drug monitoring of these drugs, which is best performed using mass spectrometry-based platforms. However, technical and logistical obstacles to implementing these platforms in hospital laboratories have limited their widespread utilization. Here, we present the development and validation of a fast and simple ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method to measure fluconazole, voriconazole, posaconazole, itraconazole, and hydroxyitraconazole in human serum suitable for incorporation into a hospital clinical laboratory...

Peng Duan, Ping Zhao, Lei Zhang
BACKGROUND: The disposition of statins varies and involves both metabolizing enzymes and transporters, making predictions of statin drug-drug interactions (DDIs) challenging. Physiologically based pharmacokinetic (PBPK) models have, however, demonstrated ability to predict complex DDIs. OBJECTIVE: In this study, PBPK models of two statins (pitavastatin and atorvastatin) were developed and applied to predict pitavastatin and atorvastatin associated DDIs. METHOD: Pitavastatin and atorvastatin PBPK models were developed using in vitro and human pharmacokinetic data in a population-based PBPK software (SimCYP(®)) by considering the contribution of both metabolizing enzymes and transporters to their overall pharmacokinetics...

REVIEW
Alessandro Busca, Anna Maria Tortorano, Livio Pagano
There is a growing body of evidence supporting the emergence of azole resistance in Aspergillus and Candida spp. and this may be of particular concern due to the potential implications in the management of invasive fungal infections occurring in immunocompromised hosts. The aim of present review was to describe the magnitude of the problem, summarising the epidemiology and potential impact of yeast and mould antifungal resistance in patients with haematological malignancies. The first cases of triazole-resistant Aspergillus fumigatus isolates were reported in 1997 in patients receiving itraconazole...

Antifungal prophylaxis regimens vary between centres, informed by local epidemiology and antifungal stewardship practices. The advantages of itraconazole over posaconazole prophylaxis include maintaining the utility of azole therapy for suspected breakthrough invasive fungal infection (bIFI). We examined the effectiveness and tolerability of itraconazole as prophylaxis in acute myeloid leukaemia (AML) patients. We sought to determine the rate of probable and proven bIFI in the context of itraconazole prophylaxis in a real-life setting...
