生物活性

CBPD-268 is a potent and orally active CBP/p300 PROTAC degrader with an DC50 value of ≤ 0.03 nM. CBPD-268 induces CBP/p300 degradation and inhibits cell growth. CBPD-268 shows antitumor activity. CBPD-268 has the potential for the research of AR-positive prostate cancer (Structure Note: Red, Androgen receptor degrader (HY-W248665A); Blue, CBP/p300 ligand (HY-161483); Black, Linker)[1].

体外研究
(In Vitro)

CBPD-268 (4, 24 h) 在 22Rv1 细胞中对 CBP 和 p300 蛋白显示出高降解效率,4 小时时 DC50 值分别为 0.01、0.03 nM[1].
CBPD-268 通过与 CBP/p300 和 CRBN 蛋白结合而显示出降解作用[1]
CBPD-268 (0-1000 nM; 4 days) 抑制细胞生长,对 22Rv1、LNCaP、VCaP 细胞的 IC50 值分别为 3.7、10.3、4.6 nM [1]

体内研究
(In Vivo)

CBPD-268 (0.3, 1, 3, 10, 30 mg/kg; p.o.; once) 单次口服 0.3-3 mg/kg 可诱导肿瘤组织中 CBP 和 p300 蛋白的降解[1].
CBPD-268 (1, 3 mg/kg; p.o.; twice a week for 1 mg/kg or 3 mg/kg weekly for 4-weeks) 显示出抗肿瘤活性[1]

Animal Model: male CB17 SCID mice (VCaP xenograft tumor)[1]
Dosage: 0.3, 1, 3, 10, 30 mg/kg
Administration: P.o.; once
Result: Induced depletion of both CBP and p300 proteins in the VCaP tumor tissue in a dose-dependent manner.
Animal Model: male CB17 SCID mice (VCaP xenograft tumor model)[1]
Dosage: 1, 3 mg/kg
Administration: P.o.; twice a week for 1 mg/kg or 3 mg/kg weekly for 4-weeks
Result: Inhibited tumor growth and shows little effect on animal body weight.
Animal Model: female BALB/c mice[1]
Dosage: 3, 10, 30 mg/kg
Administration: P.o.; twice weekly for 5-6 weeks
Result: Induced no weight loss or other signs of toxicity at both 3 and 10 mg/kg dose-levels in both male and female mice.
Animal Model: Female Sprague–Dawley (SD) rats[1]
Dosage: 1-10 mg/kg
Administration: P.o.; twice a week for 5 weeks
Result: Did not cause animal body weight loss during the entire experiment and did not induce any signs of toxicity during the entire experiment.

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.
