产品使用指南

Conglobatin (FW-04-806) 是一种从 Streptomyces conglobatus 培养物中分离得到的大环内酯双内酯。Conglobatin 是一种具有口服活性的 Hsp90 抑制剂,可以与 Hsp90 的 N 末端域结合,并破坏 Hsp90-Cdc37 复合物的形成。Conglobatin 可诱导人乳腺癌细胞和食道鳞状细胞癌细胞凋亡,并在体内表现出抗肿瘤活性。

生物活性

Conglobatin (FW-04-806), a macrolide dilactone, is isolated from the culture of Streptomyces conglobatus. Conglobatin is an orally active Hsp90 inhibitor. Conglobatin can bind to the N-terminal domain of Hsp90 and disrupt Hsp90-Cdc37 complex formation. Conglobatin induces apoptosis in human breast cancer cells and esophageal squamous cell carcinoma cells, and exhibits antitumor activity in vivo[1][2][3].

IC50 & Target[2]

HSP90

 

体外研究
(In Vitro)

Conglobatin (6.25-100 μM; 48 h) markedly inhibits the proliferation of SKBR3 and MCF-7 cells, with IC50s of 12.11 and 39.44 μM, respectively[2].
Conglobatin inhibits cell proliferation in EC109, KYSE70, KYSE450, KYSE150, KYSE180, and KYSE510 cells, with IC50s of 16.43, 15.89, 10.94, 10.50, 10.28, and 9.31 μM, respectively[3].
Conglobatin (10-40 μM; 24 h) displays obvious arrest of SKBR3 and MCF-7 cells in the G2/M phase. Conglobatin induces apoptosis through caspase-dependent pathways in SKBR3 and MCF-7 cells[2].
Conglobatin (10-40 μM; 3-24 h) reduces Hsp90 client protein levels and induces proteasome-dependent degradation[2].
Conglobatin binds to the N-terminal of Hsp90, does not affect ATP-binding capability of Hsp90, but inhibits Hsp90/Cdc37 chaperone/co-chaperone interactions[2].

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

Cell Proliferation Assay[2]

Cell Line: SKBR3 and MCF-7 cells
Concentration: 6.25, 12.5, 25, 50, 100 μM
Incubation Time: 48 hours
Result: Inhibited the proliferation of SKBR3 and MCF-7 cells in a dose-dependent manner.

Cell Cycle Analysis[2]

Cell Line: SKBR3 and MCF-7 cells
Concentration: 10, 20, 40 μM
Incubation Time: 24 hours
Result: Increased the G2/M cell population and decreased the population in the S and G0/G1 phases.

Western Blot Analysis[2]

Cell Line: SKBR3 and MCF-7 cells
Concentration: 10, 20, 40 μM
Incubation Time: 3, 6, 12, 24 hours
Result: Decreased the levels of the client proteins HER2, p-HER2, Raf-1, Akt, and p-Akt in a dose and time-dependent manner in SKBR3 cells.
Reduced the the levels of the client proteins Raf-1, Akt, and p-Akt in a dose and time-dependent manner in MCF-7 cells.
体内研究
(In Vivo)

Conglobatin (50-200 mg/kg; i.g. q3d for 24 d) inhibits the tumor growth of SKBR3 and MCF-7 human breast cancer xenograft models in a dose-dependent manner[2].
Conglobatin (4-8 mg/kg; i.p. daily for 21 days) inhibits tumor growth in EC109 and KYSE510 tumor xenograft models with low toxicity[3]

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

Animal Model: BALB/c (nu/nu) athymic mice with SKBR3 and MCF-7 tumor xenograft[2]
Dosage: 50, 100, 200 mg/kg
Administration: Oral gavage every 3 days for 24 days
Result: Showed inhibition of tumor growth at a rate of 39.1%, 52.7%, and 67.5% in the SKBR3 cell line groups and 27.3%, 39.8%, 54.3% in the MCF-7 cell line groups at the three increasing doses, respectively.
Was well tolerated.

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.
