生物活性 | hnRNPK-IN-1 is aheterogeneous nuclear ribonucleoprotein K (hnRNPK)binding ligand withKdvalues of 4.6 μM and 2.6 μM measured with SPR and MST, respectively. hnRNPK-IN-1 inhibitsc-myctranscription by disrupting the binding of hnRNPK andc-mycpromoter. hnRNPK-IN-1 induces Hela cellsapoptosisand has strongly anti-tumor activities[1]. |
IC50& Target | Kd: 4.6 μM (hnRNPK; SPR assay) and 2.6 μM (hnRNPK; MST assay)[1] |
体外研究 (In Vitro) | hnRNPK-IN-1 (Compound 25; 1.25-5 μM; 24 hours) treatment induces Hela cells apoptosis could be due to its repression of cmyc transcription[1]. hnRNPK-IN-1 (1.25-5 μM; 48 hours) treatment down-regulates c-myc gene transcription and expression in Hela cells in a dose-dependent manner[1]. hnRNPK-IN-1 shows a selective anti-proliferative effect on human cancer cell lines (Siha, A549, Hela, U2OS, A375, HuH7 and HEK293 cells) with IC50 values ranged from 1.36 to 3.59 μM[1]. hnRNPK-IN-1 could selectively bind to hnRNP K without significant interaction with c-myc promoter DNA. The binding of hnRNPK-IN-1 to hnRNP K could disrupt the interaction between hnRNP K and c-myc promoter DNA in vitro and in cells[1].
Apoptosis Analysis[1] Cell Line: | Hela cells | Concentration: | 1.25 μM, 2.5 μM, 5 μM | Incubation Time: | 24 hours | Result: | Induced Hela cells apoptosis and apoptosis-related protein expressions. |
RT-PCR[1] Cell Line: | Hela cells | Concentration: | 1.25 μM, 2.5 μM, 5 μM | Incubation Time: | 48 hours | Result: | Caused a reduction of c-myc mRNA in a dose-dependent manner in Hela cells. |
Western Blot Analysis[1] Cell Line: | Hela cells | Concentration: | 1.25 μM, 2.5 μM, 5 μM | Incubation Time: | 48 hours | Result: | The expression levels of c-MYC also decreased in a dose-dependent manner. |
