Discovery of Novel Antileishmanial Agents in an Attempt to Synthesize Pentamidine−Aplysinopsin Hybrid Molecule
摘要:
In an attempt to synthesize pent amidine - aplysinopsin hybrid molecule 25, a lead molecule 8 (containing Z-configured aplysinopsin moiety) was identified for antileishmanial activity. Optimization of lead 8 provided 24 (containing E-configured aplysinopsin) possessing 10 times more activity and 401-fold less toxicity than the drug pentamidine in cell based assays. Synthesis of 24 was possible, surprisingly, because of two innate reactivities of indole-3-carbaldehyde which provided it in diastereoand regio-selectively pure form without recourse to the long reaction pathway.
