产品介绍

KRIBB11 是HSF1的抑制剂，IC₅₀值为 1.2 μM。

生物活性

KRIBB11 is an inhibitor ofHeat shock factor 1 (HSF1), withIC₅₀of 1.2 μM.

IC₅₀& Target

HSF1

1.2 μM (IC₅₀)

体外研究
(In Vitro)

KRIBB11 blocks the induction of HSF1 downstream target proteins such as HSP27 and HSP70. KRIBB11 induces growth arrest and apoptosis of HCT-116 cells. KRIBB11 inhibits HSF1-dependent recruitment of p-TEFb (positive transcription elongation factor b) to the hsp70 promoter^[1]. PARP and caspase-3 cleavage is increased in cells treated with KRIBB11. Incubating RKO with KRIBB11, shows a toxic threshold of about 10 μM, and an IC₅₀of 20-30 μM^[2].

体内研究
(In Vivo)

KRIBB11 (50 mg/kg, i.p.) results in a 47.4% inhibition of tumor growth in nude mice, without body weight loss^[1].
