生物活性

MEL23 is a MDM2 E3 ligase inhibitor that blocks the E3 ligase activity of the MDM2-MDMX complex. MEL23 inhibits Mdm2 and p53 ubiquitination in cells, reduce viability of cells with wild-type p53. MEL23 stabilizes MDM2 via a mechanism independent of p53 transcription[1].

体外研究
(In Vitro)

MEL23 增加 Mdm2(wt)-荧光素酶细胞的发光,EC50 值为 2.7 μg/mL[1]
MEL23(3.16-100 μM;48 小时)导致 p53 依赖性细胞死亡[1]
MEL23(2.5-5 μg/mL;48 小时)增加了亚 G1 细胞群,并导致 HT-1080 细胞中 G2 细胞周期轻微停滞[1]
MEL23(5 μg/mL;6 小时)增加了 Mdm2、p53 和 MdmX 的水平并激活 p53[1]
MEL23(5 μg/mL;24-48 小时)增加了 p53 靶基因 Mdm2p21pumabax 的转录[1]
在亲本 HT-1080 细胞中,MEL23 抑制 Erastin (HY-15763) 诱导的细胞死亡,并显著降低铁死亡的程度[2]

Cell Viability Assay[1]

Cell Line: RKO cells
Concentration: 3.16-100 μM
Incubation Time: 48 hours
Result: Specifically decreased RKO cell viability.

Cell Cycle Analysis[1]

Cell Line: HT-1080 cells
Concentration: 2.5 μg/mL (7 μM), 5 μg/mL (14 μM)
Incubation Time: 48 hours
Result: Increased the sub-G1 population and caused a slight G2-cell cycle arrest.

Western Blot Analysis[1]

Cell Line: U2OS, RKO, and HCT116 cells (p53 wild-type)
Concentration: 5 μg/mL (14 μM)
Incubation Time: 6 hours
Result: Increased the Mdm2 and p53 levels.

RT-PCR[1]

Cell Line: RKO cells
Concentration: 5 μg/mL (14 μM)
Incubation Time: 24 hours, 48 hours
Result: Increased the transcription of p53 target genes, Mdm2, p21, puma, and bax.

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.
