摘要

本研究通过体外试验评估了分离或半合成单端孢霉烯倍半萜防止癌症出现和增殖以及抑制信号转导和激活转录-3（STAT3）磷酸化的能力。与 C3 上缺少羟基的单端孢霉烯（TTC）相比，C3 上带有羟基的单端孢霉烯 A（TTC-A）具有更强的防癌、抗增殖和 STAT3 磷酸化抑制作用。此外，单端孢霉烯醇 B（TTC-B）是 TTC 的还原衍生物，具有类似的细胞毒性作用，但其化学保护和 STAT3 磷酸化抑制作用大大弱于 TTC。这些结果清楚地表明，C3 处的羟基和 C8 处的羰基是诱导强效化学防护和 STAT3 磷酸化抑制的关键。

Evaluation of STAT3 Inhibition by Cancer Chemopreventive Trichothecenes Derived from Metabolites of Trichothecium roseum

This study evaluated the ability of isolated or semisynthesized trichothecene sesquiterpenes to prevent cancer emergence and proliferation and inhibit signal transducer and activator of transcription-3 (STAT3) phosphorylation through in vitro assays. Trichothecinol A (TTC-A), which bears a hydroxy group at C3, exhibited greater cancer prevention, antiproliferation, and STAT3 phosphorylation inhibition effects than trichothecin (TTC), which lacks a hydroxy group at C3. Furthermore, trichothecinol B (TTC-B), which is a reduced derivative of TTC and has similar cytotoxic effect, showed substantially weaker chemoprotection and STAT3 phosphorylation inhibition effects than TTC. These results clearly indicate that the hydroxy group at C3 and carbonyl group at C8 are crucial for inducing both potent chemoprevention and STAT3 phosphorylation inhibition.
