生物活性

CDD-1274 is an ERα (Estrogen receptor α) variant inhibitor. CDD-1274 induces proteasomal degradation of ERα variants in breast cancer cell lines and causes Y537S ERα degradation. CDD-1274 potently blocks ligand-dependent and ligand-independent ER signaling in endocrine-resistant breast cancer cells. CDD-1274 can be used for the study of breast cancer[1].

体外研究
(In Vitro)

CDD-1274 (10 μM) 可有效阻断 SRC3 共激活肽向 Y537S 和 D538G 突变型 ERα LBD 的募集[1]
CDD-1274 (0-10 μM,0-48 h) 可降低 T47D 亲代细胞和 T47D Y537S 突变体中野生型和 Y537S ERα 蛋白的水平,并伴有细胞周期蛋白 D1、survivin 和孕激素受体 (PR) 表达的降低[1]
CDD-1274 (10 μM,24 h) 可降低 MCF-7 亲代细胞和 MCF-7 Y537S 及 D538G 突变体中 ERα 蛋白的水平;降低细胞增殖标志物 (细胞周期蛋白 D1、survivin、E2F1) 和 ER 靶基因 (TFF1、GREB1、PR) 的表达;并增加凋亡标志物 c-PARP 的表达[1]
CDD-1274 (10 μM,24 小时) 可降解帕博西尼耐药的 MCF-7 WT 和 Y537S 细胞中的 WT 和 Y537S ERα,并抑制细胞周期蛋白 D1、survivin 和 TFF1 的表达[1]
CDD-1274 (10 μM,24 小时) 可降低 ER 阳性细胞 (如 T47D 和 MCF-7) 中的 ERα 和增殖标志物;在 ER 阴性细胞 (MCF-10A、HCC1954、MDA-MB-231 和 VCaP) 中,它是一种纯粹的拮抗剂 (Ishikawa 等人)[1]
CDD-1274 (10 μM,24 小时) 可诱导 T47D 亲代细胞和 T47D Y537S 细胞中 ERα 的持续降解[1]

Cell Viability Assay[1]

Cell Line: T47D parental, T47D Y537S
Concentration: 0 μM, 0.1 μM, 0.5 μM, 1 μM, 5 μM, 10 μM
Incubation Time: 0 h, 6 h, 24 h, 48 h
Result: Decreased levels of ERa protein in WT and Y537S were accompanied by decreased expression of cyclin D1, survivin, and progesterone receptor (PR).
ERA degradation began within 6 hours and disappeared completely within 48 hours; downstream markers (such as cyclin D1) also decreased in a time-dependent manner.

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.
