生物活性

Striatisporolide A is an antibacterial agent. Striatisporolide A exhibits antibacterial activity against Escherichia coli in vitro. Striatisporolide A damages the cell wall and cell membrane of Escherichia coli, and induces changes in protein levels and morphology. Striatisporolide A reduces the level of apoptosis (apoptosis) in HUVECs, inhibits excessive production of ROS, and possesses pro-proliferative and mild cytoprotective effects. Striatisporolide A can be used in studies related to bacterial infections and degenerative diseases[1][2].

体外研究
(In Vitro)

Striatisporolide A (0-400 µM; 24 h) 对 Escherichia coli ATCC 8739 表现出温和的抑菌活性,孵育 24 h 后,在 200 µM 浓度下的最大生长抑制率为 32.74%,在 400 µM 浓度下为 31.24%[1]
Striatisporolide A (200-400 µM; 20 h) 在纸片扩散法中对 Escherichia coli ATCC 8739 产生较小的抑菌圈 (200 µM 时为 7.03 mm,400 µM 时为 7.08 mm)[1]
Striatisporolide A (200-400 µM; 0-24 h) 会破坏 Escherichia coli ATCC 8739 的细胞壁,提高胞外 AKP 活性[1]
Striatisporolide A (200-400 µM; 0-2 h) 可快速破坏 Escherichia coli ATCC 8739 的细胞膜,诱导 ATP 泄漏,该泄漏在 0.5 h 时达到峰值:200 µM 处理组的 ATP 水平为 0.83 µM,400 µM 处理组为 0.96 µM[1]
Striatisporolide A (200-400 µM; 24-32 h) 可改变 Escherichia coli ATCC 8739 中的蛋白质表达:在 200 或 400 µM 浓度下孵育 24 或 32 h 后,其会提高水悬浮液中 35 kDa 蛋白的水平,并降低裂解液中 10 kDa 蛋白的水平[1]
Striatisporolide A (200-400 µM; 20 h) 可诱导 Escherichia coli ATCC 8739 发生形态改变,在 200 或 400 µM 浓度下孵育 20 h 后,该菌株会出现细胞表面粗糙、大小不规则及长度缩短的现象[1]
Striatisporolide A (200-400 µM; 24 h) 会破坏 Escherichia coli ATCC 8739 的超微结构,在 200 或 400 µM 浓度下孵育 24 h 后诱导细胞形态异常[1]
Striatisporolide A (0-150 μM; 48 h) 可促进人脐静脉内皮细胞 (HUVECs) 的增殖,在 100 μM 时效果达到峰值,可将细胞活力提升至 128.72%[2]
Striatisporolide A (0-150 μM; 48 h pre-incubation prior to 40 min H2O2 exposure) 对人脐静脉内皮细胞 (HUVECs) 中 H2O2 诱导的氧化损伤具有细胞保护活性,以 50 μM 浓度预孵育可将细胞存活率提升至 56.94%[2]
Striatisporolide A (100 μM; 48 h) 可抑制 HUVECs 在基础状态下以及 H2O2 诱导氧化应激后的凋亡,在 100 μM 浓度下可分别将凋亡率降至 2.17%和 3.1%[2]
Striatisporolide A (50-150 μM; 48 h pre-incubation prior to 40 min H2O2 exposure) 可抑制 HUVECs 中由 H2O2 诱导的细胞内 ROS 过度生成,在 100 μM 浓度下可将荧光强度降至 9.47[2]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
