Identification of a broad-Spectrum azasordarin with improved pharmacokinetic properties
摘要:
The synthesis and antifungal activity of 5- and 5'-6'-substituted azasordarin derivatives are described. Modification of the 5'-position led to the discovery of the spirocyclopentyl analogue 7g, which is the first azasordarin to register single-digit MIC values versus Aspergillus spp. Further investigation identified the 5'-i-Pr derivative 7b, which displays superior pharmacokinetic properties compared to other azasordarins.

Synthesis of Sordaricin Analogues as Potent Antifungal Agents against Candida albicans
摘要:
Sordaricin derivatives possessing a cyclohexane ring appendage attached via an ether. thioether. amine, oxime. ester or amide linkage were synthesized and their antifungal activity was evaluated in vitro. Compounds containing a thioether bond or an oxime bond as a linkage exhibited potent MICs (less than or equal to0.125 mug/mL) against four Candida albicans strains including azole-low-susceptible strains. They were also active (MIC less than or equal to0.125 mug/mL) against Candida glabrata. Their in vivo efficacy was confirmed in a murine intravenous infection model with Candida albicans.
