  Design, Synthesis, and Microbiological Evaluation of New Candida albicans CYP51 Inhibitors

  摘要：

  In a program aimed at the design and synthesis of novel azole inhibitors of Candida albicans CYP51 (CA-CYP51), a series of azole 1,4-benzothiazines (BT) and 1,4-benzoxazines (BO) were recently synthesized. A morphological study of the enzyme active site highlighted a hydrophobic access channel, and a docking study pointed out that the C-2 position of the BT or BO nucleus was oriented toward the access channel. Here, we report the design, synthesis, and microbiological evaluation of C-2-alkyl BT and BO compounds. In both series, introduction of the alkyl chain maintained and in some cases improved the anti-Candida in vitro activity; however, there was not always a strict correlation between in vitro and in vivo activity for several compounds.
