DTHIB

产品介绍

DTHIB 是一种直接和选择性的 heat shock factor 1 (HSF1) 抑制剂，DTHIB 与 HSF1 DNA 结合域结合的 K_d 为 160 nM。DTHIB 抑制 HSF1 癌症基因标记 (HSF1 CaSig)，并选择性刺激核 HSF1 的降解。DTHIB 具有有效的抗癌活性，可用于前列腺癌的研究。

生物活性

DTHIB is a direct and selective heat shock factor 1 (HSF1) inhibitor with a K_d of 160 nM for DTHIB binding to the HSF1 DNA binding domain (DBD). DTHIB inhibits HSF1 cancer gene signature (HSF1 CaSig) and selectively stimulates degradation of nuclear HSF1. DTHIB has potently anticancer activities and can be used for prostate cancer research.

体外研究

DTHIB (5 μM; 48 hours) treatment of C4-2 cells induces cell cycle arrest, with accumulation in the G1 phase. DTHIB stimulates C4-2 PCa cell entry into senescence.
DTHIB (0.5-5 μM; 48 hours; C4-2 prostate cancer) treatment reduces steady-state protein abundance of the molecular chaperones P23, HSP27, HSP70, and HSP90-all bona fide HSF1 targets in C4-2 cells.
DTHIB dose-dependently reduces the clonal expansion of both C4-2 and PC-3 PCa cells with EC₅₀ values of 1.2 μM and 3.0 μM, respectively.
In mouse embryonic fibroblasts (MEFs), DTHIB (0.5-10 μM) attenuates the robust acute heat shock induction of the HSP70 and HSP25 molecular chaperones in a dose-dependent manner. DTHIB attenuates the heat shock response by reducing the steady-state transcript abundance of multiple molecular chaperones.

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