Functionalised isocoumarins as antifungal compounds: Synthesis and biological studies
摘要:
A series of novel 3-substituted isocoumarins was prepared via Pd-catalysed coupling processes and screened in vitro for antifungal activity against Candida species. The study revealed antifungal potential of isocoumarins possessing the azole substituents, which, in some cases, showed biological properties equal to those of clinically used voriconazole. Selected compounds were also screened against voriconazole resistant Candida krusei 6258 and a clinical isolate Candida parapsilosis CA-27. Although the activity against these targets needs to be improved further, the results emphasise additional potential of this new class of antifungal compounds. (C) 2015 Elsevier Ltd.

A series of 3-hydroxy- and 3-bromobutyl-substituted isocoumarins was synthesized. The absolute configurations of three isocoumarin derivatives from Artemisia dracunculus , namely (−)-epoxyartemidin, (−)-2′-methoxydihydroartemidin, and (+)-3′-hydroxyartemidin were determined by chemical means via derivatization, kinetic racemate resolution ( Horeau method), and comparison of the circular dichroism (CD)
