  Approaches towards the stabilization of hemiaminal function at ornithine unit of mulundocandin

  摘要：

  Semisynthetic modifications at position-12 (ornithine-5-position, hemiaminal function) of mulundocandin were carried out to improve its chemical stability. New carbon-carbon (C-C) and carbon-hydrogen (C-H) linkage at hemiaminal function -12 has been achieved. Lewis acid catalyzed introduction of electron rich aryl group at position-12 of mulundocandin is developed. Synthesized mulundocandin analogues were evaluated for their chemical stability and antifungal activity against C. albicans and A. fumigatus. (C) 2004 Elsevier Ltd. All rights reserved.

  Mulundocandin (1), is an echinocandin class of lipopeptide. It has wide spectrum of antifungal activity against Candida and Aspergillus species. Semisynthetic modification at Ornithine-5-hydroxyl (hemiaminal function) of 1 was carried out to improve solution stability and hence in vivo activity. Synthesis of ether (C-OR), thioether (C-SR) and C-N linkage at hemiaminal function have been described. All synthetic analogues were evaluated for their stability in aqueous solution and found to be more stable than mulundocandin. Antifungal activity of Orn-5 analogues was evaluated both in vitro against Candida albicans and Aspergillus famigatus by agar well method and in vivo (oral and intraperitoneal) in C. albicans infected Swiss mice. Results of in vivo assays of analogues 2-9 by the oral route suggests that the introduction of either oxygen nucleophiles (-OR) or sulphur nucleophiles (-SR), at either Orn-5 or at both Orn-5 and HTyr-4 positions, results in retaining the activity of the parent compound with improved aqueous stability in most cases. Compound 9 has shown improved antifungal activity in comparison to mulundocandin by oral application in Swiss mice. (C) 2003 Elsevier Ltd. All rights reserved.
