产品介绍
CCT251236 是通过热休克转录因子 1 (hsf1) 表型筛选得到的有口服活性的吡啶配体,抑制 HSF1 介导的HSP72诱导的IC50值为 19 nM。
生物活性

CCT251236 is an orally available pirin ligand from a heat shock transcription factor 1 (hsf1) phenotypic screen with anIC50of 19 nM for inhibition of HSF1-mediatedHSP72induction.

IC50& Target[1]

HSP72

19 nM (IC50, SK-OV-3 cells)

体外研究
(In Vitro)

CCT251236 (0-100 nM; 24hours) displays a desired balance of in vitro properties, while maintaining excellent cellular activity with a pIC50=7.73 ± 0.07 (IC50=19 nM) for inhibition of HSF1-mediated HSP72 induction. The free GI50 is 1.1 nM in SK-OV-3 cells that calculated from the free fraction in the cell assay[1].
CCT251236 (0-100 nM; 24 hours) blocks 17-AAG induced he HSF1-mediated heat-shock proteins, HSP72 and HSP27 expression as a concentration manner in SK-OV-3 cells[1].
CCT251236 (0-100 nM; 24 hours), pre-treated with 250 nM 17-AAG for 6h, blocks the induction of HSPA1A mRNA by 17-AAG in a dosedependent manner[1].

Western Blot Analysis[1]

Cell Line:SK-OV-3 cells
Concentration:0 nM; 10 nM; 100 nM
Incubation Time:24 hours
Result:Inhibited HSP72 and HSP27 expression at the dose of 10 nM.

RT-PCR[1]

Cell Line:SK-OV-3 cells
Concentration:0 nM; 10 nM; 100 nM and 1000 nM
Incubation Time:24 hours
Result:Decreased HSPA1A mRNA level.
体内研究
(In Vivo)

CCT251236 (oral adminstation; 5 or 20 mg/kg) in nontumor bearing immunocompetent BALB/c mice exhibits free Cav0-24h value of 2.0 nM and 1.2 nM, respectively[2].
CCT251236 (oral adminstation; 20 mg/kg; 33 days) has a clear therapeutic efficacy in mice with a tumor growth inhibition (%TGI) of 70% based on final tumor volumes. After 33 days, the mean tumor weights decreases 64% when compares to control group. In addition, the compound’s basicity and high volume of distribution shows in tumor withtumor concentrations of CCT251236 as high as 940 nM[2].

Animal Model:Athymic mice with SK-OV-3 cells[2]
Dosage:20 mg/kg; 33 days
Administration:Oral adminstation
Result:Was efficacious in SK-OV-3 cell induced-tumor mice model.

    请依序添加每种溶剂: 10% DMSO    40%PEG300   5%Tween-80   45% saline

    Solubility: ≥ 2.5 mg/mL (4.52 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (4.52 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。
