摘要
化合物5,肉桂苯胺衍生物,上调脑衍生神经营养因子(BDNF)的表达,但具有低溶解性。在本研究中,5的n -氧化物衍生物PX5-9在HT22谷氨酸诱导的毒性模型中显示出明显的保护作用,在30 μM下无明显毒性。Western blot分析证实PX5-9增加BDNF水平与5相似。溶解度测试显示PX5-9与5 (<;15 ng / mL)。PX5-9的药代动力学研究显示其具有良好的特性,吸收快,并且可以转化为母体化合物5,提示其是BDNF相关疾病的潜在候选者。n -氧化物修饰可能是一个很好的前药设计,以提高溶解度,同时保持生物活性。
Design and characterization of N-oxide cinnamanilide derivative PX5–9: Improved solubility and BDNF upregulation
Compound 5, a cinnamanilide derivative, upregulates brain derivated neurotrophic factor (BDNF) expression but with low soluablity. In this study, PX5–9, a N-oxide derivative of 5, demonstrated significant protective effects in the HT22 glutamate-induced toxicity model and showed no significant toxicity at 30 μM. Western blot analysis confirmed that PX5–9 increased BDNF levels similar to 5. Solubility tests revealed a significant improvement in PX5–9 (37.10 ± 0.33 μg/mL) compared to 5 (< 15 ng/mL). Pharmacokinetic studies of PX5–9 revealed favorable properties, fast absorption and also can be transformated into parent compound 5, suggesting it is a potential candidate for these diseases involving with BDNF. The N-oxide modification might be a good prodrug design to enhance solubility while preserving biological activity.
