A new orbitide named ribifolin was isolated and characterized from Jatropha ribifolia using mass spectrometry, NMR spectroscopy, quantitative amino acid analysis, molecular dynamics/simulated annealing, and Raman optical activity measurements and calculations. Ribifolin (1) and its linear form (1a) were synthesized by solid-phase peptide synthesis, followed by evaluation of its antiplasmodial and cytotoxicity activities. Compound 1 was moderately effective (IC50 = 42 μM) against the Plasmodium falciparum strain 3D7.
从麻风树中分离出一种名为ribifolin的新环肽，并通过质谱、核磁共振光谱、定量氨基酸分析、分子动力学/模拟退火以及拉曼光学活性测量和计算对其进行了表征。通过固相肽合成法合成了ribifolin（1）及其线性形式（1a），随后评估了其抗疟和细胞毒性活性。化合物1对恶性疟原虫3D7株具有中等效果（IC50 = 42 μM）。
