Abstract

Invasive infections have become a global public health problem due to the increase of species resistant against antifungal therapeutics. The glucocorticoid PYED-1 (pregnadiene-11-hydroxy-16α,17α-epoxy-3,20-dione-1) has antimicrobial activity against various bacterial taxa. Consequently, it might be considered for the treatment of infections. The antifungal activity of PYED-1 was evaluated against several fungal strains that were representative of the five species that causes the majority of infections-namely, , , , and . PYED-1 exhibited a weak antifungal activity and a fungistatic effect on all five species. On the other hand, PYED-1 exhibited a good anti-biofilm activity, and was able to eradicate the preformed biofilms of all species analyzed. Moreover, PYED-1 inhibited germ tube and hyphae formation of and reduced adhesion of to abiotic surfaces by up to 30%.

摘要

由于对抗真菌治疗产生耐药性的物种增加，侵袭性感染已成为一个全球公共卫生问题。糖皮质激素PYED-1（孕二烯-11-羟基-16α,17α-环氧-3,20-二酮-1）对多种细菌类群具有抗菌活性。因此，它可能被考虑用于治疗感染。针对几种代表导致大多数感染的五个物种的真菌菌株，评估了PYED-1的抗真菌活性，这五个物种分别是、、、和。PYED-1对所有五个物种均表现出较弱的抗真菌活性和抑菌作用。另一方面，PYED-1表现出良好的抗生物膜活性，并且能够根除所分析的所有物种的预先形成的生物膜。此外，PYED-1抑制了和的芽管和菌丝形成，并使与非生物表面的粘附减少了高达30%。
