生物活性

RP-1664 is a selective and orally active PLK4 inhibitor with an IC50 of 3 nM. RP-1664 demonstrates exquisite selectivity over related kinases, including AURKA/B and PLK1. RP-1664 disrupts centriole biogenesis in cancer cells and leads an accumulation of PLK4 and p21 protein. RP-1664 demonstrates increased sensitivity in TRIM37-high-expressing cells or tumors. RP-1664 exhibits anti-tumor activity in breast cancer and neuroblastoma research[1][2].

RP-1664 (1-1000 nM, 48-72 h) 可剂量依赖性地上调 RPE1-hTERT Cas9 TP53 缺失细胞中的总 PLK4 蛋白水平,并增加 RPE1-hTERT Cas9 TP53 野生型细胞中的 p21 蛋白表达[1]
RP-1664 (0.001-10 μM) 在 TRIM37 过表达/TP53 野生型细胞中显示出相比 TRIM37 正常/TP53 敲除细胞约 30 倍的敏感性增强,而在 TRIM37 高表达/TP53 敲除细胞和 TRIM37 正常/TP53 野生型细胞中表现出中等活性[1]

RP-1664 (1-1000 nM, 48-72 h) 在 25-100 nM 浓度范围内,可导致 p53 正常和缺失的 RPE1 细胞产生多余中心体[1]
RP-1664 (0-2000 nM, 48 h) 以依赖高 TRIM37 蛋白水平和功能性 p53 的方式,增强细胞对 PLK4 抑制和中心体耗竭的敏感性[1]
RP-1664 (compound 37) 降低 MCF7 细胞活力的 EC50 为 0.051 μM[2]

Animal Model: Female BALB/c Nude mice were supplemented with estradiol in drinking water (2.5 µg/mL) and gamma irradiated (1.2 Gy) 1 week and 24-72 hours prior to inoculation in the right flank using 10 million MCF7 cells[1]
Dosage: 600 ppm
Administration: p.o. on schedules of 7 days on/7 off or 14 days on/7 off or daily for 40 days
Result: Inhibited the tumor growth with maximal tumor growth inhibition (TGI) of 95% at 600 parts per million (ppm).
Animal Model: Female CB/17 SCID mice were inoculated in the right flank with 10 million cells of either parental CHP134, CHP134 TP53-KO or CHP134 TRIM37-KO[1]
Dosage: 300 ppm
Administration: p.o. on schedules of 17 days on/7 off for 40 days
Result: Suppressed tumor growth regardless of TRIM37 or TP53 inactivation.
Animal Model: Female SCID-beige mice xenografted with CAL-148 cells (5-7 weeks) (107 cells per mouse)[2]
Dosage: 6, 11, 21 mg/kg
Administration: i.g. for 35 days
Result: Showed tumor growth inhibition at 6 mg/kg.
Showed tumor growth stasis at 11 mg/kg.
Showed tumor growth regressions at 21 mg/kg.
Increased protein levels of PLK4 or p21 for 4 to 11 days.
Animal Model: Female CB-17 SCID mice bearing subcutaneous CHP-134 xenografts (5-7 weeks) (107 cells per mouse)[2]
Dosage: 300, 600 ppm
Administration: p.o. on schedules of 3 days on/4 off or 14 days on/7 off or daily for 55 days
Result: Improved the tumor regressions efficacy with longer continuous exposure.
Improved tolerability with intermittent dosing, whereas continuous dosing at 600 ppm was not tolerated beyond day 46.
Increased protein levels of PLK4 or p21 for 4 to 11 days.

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.
