The aim of this study was to investigate how the signaling pathway downstream of mTOR/S6K1 contributes to the regulation of SREBP-1c expression during lipogenesis in HepG2 cells. The model of steatosis was established using human hepatocytes HepG2 and inducting them with sodium palmitate. mTOR, S6K1 and LXRα were inhibited by rapamycin, PF-4708671 and siRNA-LXRα, resp. After a variety of different treatment, the levels of intracellular triglycerides, the accumulation of lipid droplets and the expression levels of related genes were detected. Rapamycin, PF-4708671 and siRNA-LXRα treatment could decrease the accumulation of triglycerides and lipid droplets induced by sodium palmitate in HepG2 cells, and the inhibitory effect could be enhanced by the combination of them. Sodium palmitate stimulated the expression of genes encoding mTOR, S6K1, LXRα, SREBP-1c and SREBP-1c target enzymes (FAS and ACC1) in HepG2 cells. Moreover, these genes were sensitive to rapamycin. The PF-4708671 also decreased the expression of these genes, except for the mTOR gene, and the extent of reduction could be enhanced by combination with rapamycin. Knockdown of LXRα decreased the expression of SREBP-1c, FAS and ACC1, but it had no effect on the expression of mTOR or S6K1. Furthermore, rapamycin and PF-4708671 enhanced the inhibitory effect of siRNA-LXRα. A mTOR/S6K1 regulates the SREBP-1c signaling pathway through LXRα in sodium palmitate-induced HepG2 cells, suggesting LXRα might be a potential therapeutic target for NAFLD.

S6K1 inhibits HBV replication through inhibiting AMPK-ULK1 pathway and disrupting acetylation modification of H3K27 was written by Wang, Yun;Han, Ming;Liu, Shunai;Yuan, Xiaoxue;Zhao, Jing;Lu, Hongping;Han, Kai;Liang, Pu;Cheng, Jun. And the article was included in Life Sciences in 2021.SDS of cas: 1255517-76-0 This article mentions the following:

To investigated the effect of S6K1 on the replication and transcription of HBV DNA using multiple cell models. The pgRNA, total HBV RNA and HBV DNA level were detected by Real-time PCR. The HBcAg expression by Western blot and the activity of four HBV promoters, such as preS1, preS2/S, core, and X promoters by using dual luciferase reporter assay. Moreover, we determined S6K1 interacted with HBcAg in both cytoplasm and nucleus through Immunofluorescence, co-immunoprecipitation (CoIP) and Western blot. S6K1 inhibited HBV DNA replication and cccDNA-dependent transcription in HBV-expressing stable cell lines. The mechanistic study revealed that S6K1 suppressed HBV DNA replication by inhibiting AMPK-ULK1 autophagy pathway, and the nuclear S6K1 suppressed HBV cccDNA-dependent transcription by inhibiting the acetylation modification of H3K27. In addition, HBV capsid protein (HBcAg) suppressed the phosphorylation level of S6K1Thr389 by interacting with S6K1, indicating a viral antagonism of S6K1-mediated antiviral mechanism. The p70 ribosomal S6 kinase (S6K1) is a serine/threonine protein kinase, and it plays a significant role in different cellular processes. It has been previously reported that S6K1 affects hepatitis B virus (HBV) replication but the underlying mechanism remains unclear. In this study, our data suggested that the activation of S6K1 restricts HBV replication through inhibiting AMPK-ULK1 autophagy pathway and H3K27 acetylation. These findings indicated that S6K1 might be a potential therapeutic target for HBV infection. In the experiment, the researchers used many compounds, for example, 2-((4-(5-Ethylpyrimidin-4-yl)piperazin-1-yl)methyl)-6-(trifluoromethyl)-1H-benzo[d]imidazole (cas: 1255517-76-0SDS of cas: 1255517-76-0).

The p70S6K specific inhibitor PF-4708671 impedes non-small cell lung cancer growth was written by Qiu, Zhi-Xin;Sun, Rong-Fei;Mo, Xian-Ming;Li, Wei-Min. And the article was included in PLoS One in 2016.Related Products of 1255517-76-0 This article mentions the following:

Background: As a serine/threonine protein kinase, p70S6K plays an important role in tumor cells. Evidence has revealed overexpression of p70S6K and phosphorylated p70S6K (p-p70S6K) in various tumor tissues, with these proteins identified as independent prognostic markers in non-small cell lung cancer (NSCLC). In this study, we explored the role of the p70S6K specific inhibitor PF-4708671 in NSCLC. Methods: Three NSCLC cell lines (A549, SK-MES-1, and NCI-H460) were treated with PF-4708671 at five different concentrations, including 0.1μM, 0.3μM, 1μM, 3μM and 10μM, and protein levels were determined by Western-blot. Then, PF-4708671’s effects were assessed both in vitro (cell proliferation, apoptosis, cell cycle distribution, and invasion) and in vivo. Results: The expression levels of p-p70S6K and the downstream effector S6 were significantly reduced by PF-4708671. Diametrically opposite, the downstream protein levels of BAD, Caspase3 and ERK had increased after treatment with PF-4708671. In addition, PF-4708671 drastically inhibited cell proliferation and invasion ability in A549, SK-MES-1 and NCI-H460 cells in vitro, causing cell cycle arrest in G0-G1 phase. Limited effects of PF-4708671 were observed on apoptosis in the three NSCLC cell lines assessed. Importantly, PF-4708671 could inhibit tumorigenesis in nude mice in vivo. Conclusion: These findings demonstrated that the p70S6K specific inhibitor PF-4708671 has inhibitory effects on NSCLC tumorigenesis in vitro and in vivo. Therefore, P70S6K should be considered a new potential therapeutic target, and PF-470867 may be used as targeted drug for cancer treatment.

2-((4-(5-Ethylpyrimidin-4-yl)piperazin-1-yl)methyl)-6-(trifluoromethyl)-1H-benzo[d]imidazole (cas: 1255517-76-0) belongs to piperazine derivatives. The piperazine scaffold is often found in biologically active compounds in different therapeutic areas. These therapeutic areas include antifungals, antidepressants, antivirals, and serotonin receptor (5-HT) antagonists/agonists. Although many piperazine derivatives occur naturally, piperazine itself can be synthesized by reacting alcoholic ammonia with 1,2-dichloroethane, by the action of sodium and ethylene glycol on ethylene diamine hydrochloride, or by reduction of pyrazine with sodium in ethanol.Related Products of 1255517-76-0

Purpose: The unique metabolic profile of cancer (aerobic glycolysis) is an attractive therapeutic target for cancer. Dichloroacetate (DCA), an inhibitor of pyruvate dehydrogenase kinase, has been shown to reverse glycolytic phenotype and induce mitochondrion-dependent apoptosis. In the present study, we investigated the effects of S6 kinase 1 (S6K1) inhibition on DCA-induced cell death and the underlying mechanisms in breast cancer cells. Methods: Cell death was evaluated by annexin V and PI staining. The synergistic effects of DCA and PF4708671 were assessed by isobologram anal. Small interfering RNA (siRNA) was used for suppressing gene expression. The mRNA and protein levels were measured by RT-PCR and Western blot anal., resp. Results: PF4708671, a selective inhibitor of S6K1, and knockdown of S6K1 with specific siRNA enhanced DCA-induced cell death. Interestingly, a combination of DCA/PF4708671 markedly reduced protein expression of a glycolytic enzyme, hexokinase 2 (HK2). Suppression of HK2 activity using specific siRNA and 2-deoxyglucose (2-DG) further enhanced cell sensitivity to DCA/PF4708671. Overexpression of Myc-tagged HK2 rescued cell death induced by DCA/PF4708671. Conclusions: Based on these findings, we propose that inhibition of S6K1, in combination with the glycolytic inhibitor, DCA, provides effective cancer therapy.

Research progress of 70 kDa ribosomal protein S6 kinase (P70S6K) inhibitors as effective therapeutic tools for obesity, type II diabetes and cancer was written by Zhang, Na;Ma, Shutao. And the article was included in Current Medicinal Chemistry in 2020.Reference of 1255517-76-0 This article mentions the following:

At present, diseases such as obesity, type II diabetes and cancer have brought serious health problems, which are closely related to mTOR pathway. 70 kDa ribosomal protein S6 kinase (p70S6K), as a significant downstream effector of mTOR, mediates protein synthesis, RNA processing, glucose homeostasis, cell growth and apoptosis. Inhibiting the function of p70S6K can reduce the risk of obesity which helps to treat dyslipidemia, enhance insulin sensitivity, and extend the life span of mammals. Therefore, p70S6K has become a potential target for the treatment of these diseases. So far, except for the first p70S6K specific inhibitor PF-4708671 developed by Pfizer and LY2584702 developed by Lilai, all of them are in preclin. research. This paper briefly introduces the general situation of p70S6K and reviews their inhibitors in recent years, which are mainly classified into two categories: natural compounds and synthetic compounds In particular, their inhibitory activities, structure-activity relationships (SARs) and mechanisms are highlighted.
