Abstract
INTRODUCTION The incidence of Aspergillus infections has recently increased remarkably in certain tropical and sub-tropical countries, with Aspergillus flavus being identified as the leading cause of infections after A. fumigatus. Lanoconazole (LAN) and luliconazole (LUL) are currently approved for topical treatment of cutaneous fungal infections. We aimed the in-vitro antifungal susceptibility testing of two imidazole, LAN and LUL against A. flavus. METHODS One hundred and eighty-seven clinical and environmental A. flavus were tested originating from different climate zones of Iran between 2008 and 2015. The identification of all isolates was confirmed by using PCR-sequencing of β-tubuline ribosomal DNA gene. In-vitro antifungal susceptibility test was performed using CLSI guidelines against LAN, LUL, itraconazole (ITC), voriconazole (VRC), posaconazole (POS), Isavuconazole (ISA), amphotericin B (AMB), 5-flucytosine (5FC), caspofungin (CAS) and anidulafungin (AFG). The minimum inhibitory concentration (MIC) and minimum effect concentration (MEC) values were evaluated according to CLSI M38-A2 guidelines. RESULTS The geometric mean MICs for tested antifungals, in increasing order, were: 0.009 μg/mL for LUL (ranging from 0.004 to 0.062), 0.02 μg/mL for LAN (ranging from 0.004 to 0.125), POS (0.10), ISA (0.16), ITC (0.24), VRC (0.27), AMB (1.8) and 5FC (63.06) μg/mL. The mean value of MECs for AFG and CAS were 0.06 and 0.07, respectively. CONCLUSION Overall, LUL and LAN showed the lowest MIC against all isolates of A. flavus. Further studies are required to evaluate the in-vivo efficacy of these agents, and the possibility of using these agents in systemic infections.

Abstract
Topical antifungal agents which have anti-inflammatory effects have the potential to provide additional clinical benefits. Therefore, an anti-inflammatory activity of lanoconazole (LCZ), a topical antifungal agent, was investigated against in vitro and in vivo models of inflammation. The release of interleukin-8 (IL-8) from human epidermal keratinocytes stimulated by the addition of 100 μg ml(-1) β-glucan of Saccharomyces cerevisiae was significantly inhibited by LCZ at the concentration of 10(-5) mol l(-1). The release of interferon-γ and IL-2 from human peripheral blood mononuclear cells stimulated by the addition of 30 and 100 μg ml(-1) phytohemagglutinin was significantly inhibited by LCZ at the concentrations of 10(-7) and 10(-6) mol l(-1), respectively. The increase in the ear thickness induced by topical application of 0.01% 12-O-tetradecanoyl phorbol-13-acetate and 1% 2,4,6-trinitrochlorobenzene (TNCB) after sensitisation with 3% TNCB were established as the mouse models of irritant and contact dermatitis, respectively. Application of 1% and 3% LCZ showed a significant anti-inflammatory activity against both the irritant and contact dermatitis models. These findings suggest that LCZ possesses an anti-inflammatory activity, which may be partially helpful in the treatment of dermatomycoses.
