生物活性

PROTAC BCR-ABL Degrader-2 is a selective Bcr-AblT315 PROTAC degrader with a DC50 of 108.7 nM in Ba/F3 Bcr-AblT315I cells. PROTAC BCR-ABL Degrader-2 exhibits the most potent degradation efficacy with DR of 69.89% and 94.23% at 100 and 300 nM, respectively. PROTAC BCR-ABL Degrader-2 demonstrates high plasma exposure, and induces significant tumor regression and induces tumor cell apoptosis with a good safety profile in vivo. PROTAC BCR-ABL Degrader-2 can be used for chronic myeloid leukemia (CML) research[1][2]. (Pink: Bcr-Abl ligand (HY-15666); Blue: Cereblon ligand (HY-10984); Black: linker).

体外研究
(In Vitro)

PROTAC BCR-ABL Degrader-2 (Compound 7o) 针对 K562 及 Ba/F3 Bcr-AblWT 细胞的IC50 分别为 7.7 nM 与 4.2 nM[1]
PROTAC BCR-ABL Degrader-2 (0-300 nM) 在 Ba/F3 Bcr-AblT315I 细胞中可显著降低 Bcr-AblT315I 蛋白水平,DC50 为108.7 nM[1]
PROTAC BCR-ABL Degrader-2 (0-300 nM,0-48 小时) 在 Bcr-AbllT315I 细胞中通过 CRBN E3泛素化途径诱导 Bcr-AblT315I 蛋白降解,并呈现"钩状效应" [1]

Western Blot Analysis[1]

Cell Line: Ba/F3 Bcr-AblT315I and K562 cells
Concentration: 100 nM
Incubation Time: 0, 1, 2, 4, 6, 8, 10, 12, 24, 36 and 48 h
Result: Caused the degradation of Bcr-AblT315I protein in a time-dependent manner.
Reduced Bcr-AblT315I protein level substantially after 6h treatment while appeared a “hook” effect during 8-10h treatment.
Observed the maximum degradation after24h treatment.
Displayed a different trend for reducing Bcr-AblWT in K562cells with substantially reduction after 36h treatment (this different might be associated with the different states of E3 ligase in Ba/F3Bcr-AblT315I and K562 cells.).

Immunofluorescence[1]

Cell Line: MG132 (HY-13259) (20 ) Ba/F3 Bcr-AblT315I cells
Concentration: 100 and 300 nM
Incubation Time: 24 h
Result: Induced Bcr-AblT315I degradation rescuing by MG132.
体内研究
(In Vivo)

PROTAC BCR-ABL Degrader-2 (compound 7o) (20 mg/kg,单次腹腔注射) 在 ICR 小鼠中血浆浓度在 48 小时内维持较高水平[1]
PROTAC BCR-ABL Degrader-2 (10-20 mg/kg,腹腔注射,每两日一次、持续 14 天) 在 Ba/F3 Bcr-AblT315I 异种移植瘤小鼠模型中,展现出显著的抗肿瘤活性与良好的安全性[1]

Animal Model: Ba/F3 cells expressing Bcr-AblT315I (2 x 106 cells/0.1 mL) induced-CB17-SCID mice [1]
Dosage: 10 or 20 mg/kg
Administration: i.p., once every two days for 14 days
Result: Obviously sup pressed the growth of Ba/F3 Bcr-AblT315I xenograft tumor with a tumor growth inhibition (TGI) value of 90.8% at the dose of 20 mg/kg.
Induced the Bcr-AblT315I degradation and apoptosis.
Resulted no mortality or significant body weight loss.

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.
