生物活性

Anticancer peptoid 1 (Peptoid 1) is a peptoid with antitumor activity. Anticancer peptoid 1 exerts cytotoxicity primarily via plasma membrane damage. Anticancer peptoid 1 exerts cytotoxicity against a broad range of cancer cell lines, including those with multidrug resistance. Anticancer peptoid 1 inhibits tumor growth in a human breast cancer xenotransplantation mouse model without noticeable acute adverse effects. Anticancer peptoid 1 can be used for the research of cancer, such as breast cancer, and prostate cancer[1].

体外研究
(In Vitro)

Anticancer peptoid 1 (72 h) 可强效诱导 MCF-7、LNCaP、OVCAR-3、MRC-5 细胞及原代真皮成纤维细胞产生细胞毒性,处理 72 h 后的 LC50 值分别为 5、5、6、8 和 8 μM[1]
Anticancer peptoid 1 (0-50 μM; 72 h) 可强效诱导 MCF-7 细胞及多药耐药 MCF-7/TxT50 细胞产生细胞毒性,从而逆转多药耐药性[1]
Anticancer peptoid 1 (50 μM; 5-60 min) 可在 MCF-7 细胞中诱导快速的质膜损伤,50 μM 浓度在短期处理后可引发约 50% 的 LDH 泄漏[1]

Cell Cytotoxicity Assay[1]

Cell Line: MCF-7 (human breast cancer) cells
Concentration: 50 μM (for 50% LDH leakage measurement)
Incubation Time: 5, 30, 60 min
Result: Caused fast LDH release into media; 50 μM peptoid 1 induced ~50% LDH leakage.
Induced rapid plasma membrane damag.
体内研究
(In Vivo)

Anticancer peptoid 1 (1 mg/kg;乳腺脂肪垫注射;每周 3 次;共 12 周) 在人乳腺癌原位异种移植小鼠模型中可显著抑制肿瘤生长,且未观察到急性毒性[1]

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

Animal Model: NOD.Cg-Prkdcscid Il2rgtmlWjl/SzJ (NSG) (4-8 week old female, immunocompromised, orthotopic xenograft model via mammary fat pad injection of human breast cancer cells)[1]
Dosage: 1 mg/kg
Administration: Mammary fat pad injection; three times per week; 12 weeks
Result: Significantly inhibited tumor growth compared to the control peptoid, with a p-value of 0.0014.
Showed no noticeable acute adverse effects.

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.
