Abstract

The in vitro antifungal activity of aspirin against cryptococcal cells has been reported. However, the unwanted effects of aspirin may limit its clinical application. Conceivably, a derivative of aspirin could overcome this challenge. Toward this end, this study considered the usage of an aspirinate-metal complex, namely, copper acyl salicylate (CAS), as an anti-Cryptococcus antifungal agent. Additionally, the study examined the effects of this compound on macrophage function. The in vitro susceptibility results revealed that cryptococcal cells were vulnerable (in a dose-dependent manner) to CAS, which might have effected growth inhibition by damaging cryptococcal cell membranes. Interestingly, when CAS was used in combination with fluconazole or amphotericin B, synergism was observed. Furthermore, CAS did not negatively affect the growth or metabolic activity of macrophages; rather, it sensitized those immune cells to produce interferon gamma and interleukin 6, which, in turn, might have aided in the phagocytosis of cryptococcal cells. Compared to our aspirin data, CAS was noted to be more effective in killing cryptococcal cells (based on susceptibility results) and less toxic toward macrophages (based on growth inhibition res...Continue Reading

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
