Avocatin-B (Avo-B), an avocado-derived 1:1 mixture of the polyhydroxylated alcohols avocadyne (AYNE) and avocadene, eliminated leukemia cells by suppressing fatty acid oxidation (FAO) in vivo and in vitro while sparing healthy blood cells. In this study, we identified AYNE as the most potent FAO inhibitor within the Avo-B mixture capable of inducing cell death in leukemia cells lines (IC50: 3.10 ± 0.14 µM in TEX cells; 11.53 ± 3.32 µM in OCI-AML2) and patient-derived acute myeloid leukemia cells. When added individually, the two Avo-B constituents demonstrated antagonism (Combination Index values >1), highlighting the need for future studies to assess AYNE alone. Together, this work highlighted AYNE as the most potent FAO inhibitor within the Avo-B mixture.

鳄梨衍生的鳄梨素是一种有效的脂肪酸氧化抑制剂

Avocatin-B (Avo-B) 是一种源自鳄梨的多羟基化醇鳄梨 (AYNE) 和鳄梨烯的 1:1 混合物,通过在体内和体外抑制脂肪酸氧化 (FAO) 来消除白血病细胞,同时保留健康的血细胞。在这项研究中,我们将 AYNE 鉴定为 Avo-B 混合物中最有效的 FAO 抑制剂,能够在白血病细胞系中诱导细胞死亡(在 TEX 细胞中 IC 50:3.10 ± 0.14 µM;在 OCI-AML2 中为 11.53 ± 3.32 µM)和患者来源的急性髓细胞白血病细胞。当单独添加时,两种 Avo-B 成分表现出拮抗作用(组合指数值 >1),突出表明未来研究需要单独评估 AYNE。总之,这项工作突出了 AYNE 作为 Avo-B 混合物中最有效的 FAO 抑制剂。
