Conglobatin  (Synonyms: FW-04-806)

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].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
