structural congeners of natural izenamides A, B, and C (1–3) responsible for cathepsin D (CTSD) inhibition. Structurally modified izenamides were synthesized and biologically evaluated, and their biologically important core structures were identified. We confirmed that the natural statine (Sta) unit (3S,4S)-γ-amino-β-hydroxy acid is a requisite core structure of izenamides for inhibition of CTSD, which
本研究旨在阐明负责组织蛋白酶 D (CTSD) 抑制的天然 izenamides A、B 和 C (1–3) 的结构同类物。合成了结构修饰的 izenamides 并对其进行了生物学评估,并确定了其生物学上重要的核心结构。我们证实天然的他汀 (Sta) 单元 (3S,4S)-γ-氨基-β-羟基酸是依那酰胺抑制 CTSD 所必需的核心结构,它与许多人类疾病的病理生理作用密切相关。有趣的是,掺入他汀的 izenamide C 变体 (7) 和 18-epi-izenamide B 变体 (8) 表现出比天然 izenamides 更有效的 CTSD 抑制活性。
