  3. Gallium hematoporphyrin

Gallium hematoporphyrin 是一种血红素类似物,也是针对 Mycobacteroides abscessus 的选择性靶向剂。Gallium hematoporphyrin 可诱导 ROS 产生,抑制生物膜形成,同时破坏 Mycobacteroides abscessus 光滑型和粗糙型菌落形态的预成生物膜。Gallium hematoporphyrin 会干扰血红素依赖性代谢通路,抑制临床分离的 Mycobacteroides abscessus 菌株的生长,其 MIC 范围为 0.5 至 1 μg/mL。Gallium hematoporphyrin 与 Clarithromycin (HY-17508) 联用对 Mycobacteroides abscessus 具有协同抗菌活性。Gallium hematoporphyrin 可用于 Mycobacteroides abscessus 感染的相关研究。

生物活性

Gallium hematoporphyrin is a heme analogue and a selective targeting agent against Mycobacteroides abscessus. Gallium hematoporphyrin induces ROS production and inhibits biofilm formation as well as disrupts preformed biofilms in both smooth and rough colony morphotypes of Mycobacteroides abscessus. Gallium hematoporphyrin interferes with heme-dependent metabolic pathways and suppresses the growth of clinical Mycobacteroides abscessus isolatess, with MICs ranging from 0.5 to 1 μg/ml. Gallium hematoporphyrin exhibits synergistic antibacterial activity with Clarithromycin (HY-17508) against Mycobacteroides abscessus. Gallium hematoporphyrin can be used for the research of Mycobacteroides abscessus infection[1].

体外研究
(In Vitro)

Gallium hematoporphyrin (GaHP) (0.5-1 μg/mL) 可在铁限制型 7H9 培养基中抑制临床 M. abscessus 分离株 (包括光滑型和粗糙型) 的生长,其 MICs 为 0.5 和 1 μg/mL[1]
Gallium hematoporphyrin (0.0625 μg/mL; in combination with clarithromycin) 与克拉霉素协同作用于 M. abscessus,其 FICI 为 0.31,GaHP 的 FIC 为 0.0625 μg/mL[1]
Gallium hematoporphyrin (最高 32 μg/mL) 对 Vero E6 细胞无毒性[1]
Gallium hematoporphyrin (1 μg/mL (1.5 μM); 65 h) 可通过靶向血红素利用通路抑制 M. abscessus 的生长,在 1 μg/mL (1.5 μM) GaHP 作用 65 h 的条件下,血红素 (而非 FAC) 可恢复其生长[1]
Gallium hematoporphyrin (0.03-16 μg/mL; 3 h) 可在孵育 3 h 后于 0.03 至 8 μg/mL 的浓度下诱导 M. abscessus 产生浓度依赖性 ROS,而 16 μg/mL 浓度下因细胞死亡导致 ROS 生成减少[1]
Gallium hematoporphyrin (8 μg/mL) 可抑制富铁培养基中光滑型和粗糙型脓肿分枝杆菌的生物膜形成,对光滑型变异株的抑制率约为 60%,对粗糙型变异株的抑制率约为 30%[1]
Gallium hematoporphyrin (16 μg/mL) 可破坏光滑型和粗糙型脓肿分枝杆菌的预形成生物膜,对光滑型变异株生物膜的破坏率约为 50%,对粗糙型变异株生物膜的破坏率约为 40%[1]

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.
