Arf1-GEFs-IN-1 is a potent and orally active ADP-ribosylation factor 1- guanine nucleotide exchange factors (Arf1-GEFs) inhibitor with an IC50 value of 40.85 μM against CT26 cells. Arf1-GEFs-IN-1 primarily mediates tumor regression by triggering anti-tumor immune responses, rather than through direct cytotoxicity. Arf1-GEFs-IN-1 effectively promotes CCL5 expression, demonstrates excellent in vivo efficacy. Arf1-GEFs-IN-1 can be used for the study of colon cancer.

生物活性

Arf1-GEFs-IN-1 is a potent and orally active ADP-ribosylation factor 1- guanine nucleotide exchange factors (Arf1-GEFs) inhibitor with an IC50 value of 40.85 μM against CT26 cells. Arf1-GEFs-IN-1 primarily mediates tumor regression by triggering anti-tumor immune responses, rather than through direct cytotoxicity. Arf1-GEFs-IN-1 effectively promotes CCL5 expression, demonstrates excellent in vivo efficacy. Arf1-GEFs-IN-1 can be used for the study of colon cancer[1].

体外研究
(In Vitro)

Arf1-GEFs-IN-1 (Compound 18a) exhibits superior tumor suppression (80.7%) in CT26 cells and demonstrates a much-improved safety profile, with an IC50 of 193.6 μM on 3T3 cells[1].
Arf1-GEFs-IN-1 (2-50 μM) does not directly activate T cells, but instead exerts its effects by modulating the immune micro­environment through tumor cells, likely enhancing its immunogenicity through Arf1 inhibition in CT26 cells[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Arf1-GEFs-IN-1 (Compound 18a) 在小鼠肝脏微粒体 (MLM,半衰期 t1/2 = 31.1 min) 和人类肝脏微粒体 (HLM, t1/2 = 59.2 min) 中的半衰期均较短,并且在小鼠 (94.9%) 和人类 (94.1%) 血浆中的血浆蛋白结合率均较低[1]
Arf1-GEFs-IN-1 (5 mg/kg, p.o., 持续 2 周) 显著抑制了小鼠 CT26 结肠癌异种移植模型中的肿瘤生长[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.
