Title: Novel Carboline Fungal Histone Deacetylase (HDAC) Inhibitors for Combinational Treatment of Azole-Resistant Candidiasis.
Authors: Li Z,Tu J,Han G,Liu N,Sheng C
Abstract: Due to the evolution and development of antifungal drug resistance, limited efficacy of existing drugs has led to high mortality in patients with serious fungal infections. To develop novel antifungal therapeutic strategies, herein a series of carboline fungal histone deacetylase (HDAC) inhibitors were designed and synthesized, which had potent synergistic effects with fluconazole against resistant Candida albicans infection. In particular, compound D12 showed excellent in vitro and in vivo synergistic antifungal efficacy with fluconazole to treat azole-resistant candidiasis. It cooperated with fluconazole in reducing the virulence of C. albicans by blocking morphological mutual transformation and inhibiting biofilm formation. Mechanism studies revealed that the reversion of drug resistance was due to downregulation of the expression of the azole target gene ERG11 and efflux gene CDR1. Taken together, fungal HDAC inhibitor D12 offered a promising lead compound for combinational treatment of azole-resistant candidiasis.
