We’ll be discussing some of the latest developments in chemical about CAS: 127956-11-0, Name is Methyl 4-oxotetrahydro-2H-pyran-3-carboxylate, molecular formula is C7H10O4. In a Article，once mentioned of 127956-11-0, Synthetic Route of 127956-11-0

Valosine containing protein (VCP/p97) is a member of the AAA ATPase family involved in several essential cellular functions and plays an important role in the ubiquitin-mediated degradation of misfolded proteins. P97 has a significant role in maintaining the cellular protein homeostasis for tumor cell growth and survival and has been found overexpressed in many tumor types. No new molecule entities based on p97 target were approved in clinic. Herein, a series of novel pyrimidine structures as p97 inhibitors were designed and synthesized. After enzymatic evaluations, structure-activity relationships (SAR) were discussed in detailed. Among the screened compounds, derivative 35 showed excellent enzymatic inhibitory activity (IC50, 36 nM). The cellular inhibition results showed that compound 35 had good antiproliferative activity against the non-small cell lung cancer A549 cells (IC50, 1.61 muM). Liver microsome stability showed that the half-life of compound 35 in human liver microsome was 42.3 min, which was more stable than the control CB-5083 (25.8 min). The in vivo pharmacokinetic results showed that the elimination phase half-lives of compound 35 were 4.57 h for ig and 3.64 h for iv, respectively and the oral bioavailability was only 4.5%. These results indicated that compound 35 could be effective for intravenous treatment of non-small cell lung cancer.

Electric Literature of 2081-44-9. Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. Like 2081-44-9, Name is Tetrahydro-2H-pyran-4-ol. In a document type is Article, introducing its new discovery.

Acetyl-coA carboxylase 1 (ACC1) is the first and rate-limiting enzyme in the de novo fatty acid synthesis (FASyn) pathway. In this study, through public database analysis and clinic sample test, we for the first time verified that ACC1 mRNA is overexpressed in non-small-cell lung cancer (NSCLC), which is accompanied by reduced DNA methylation at CpG island S shore of ACC1. Our study further demonstrated that higher ACC1 levels are associated with poor prognosis in NSCLC patients. Besides, we developed a novel synthetic route for preparation of a known ACC inhibitor ND-646, synthesized a series of its derivatives and evaluated their activity against the enzyme ACC1 and the A549 cell. As results, most of the tested compounds showed potent ACC1 inhibitory activity with IC50 values 3?10 nM. Among them, compounds A2, A7 and A9 displayed strong cancer inhibitory activity with IC50 values 9?17 nM by impairing cell growth and inducing cell death. Preliminary SAR analysis clearly suggested that (R)-configuration and amide group were vital to ACC1 and A549 inhibition, since compound (S)-A1 (the enantiomer of ND-646) had poor activity of ACC1 inhibition and the carboxylic acid ND-630 almost lost anticancer effect on A549 cells. Collectively, these findings indicate that ACC1 is a potential biomarker and target for non-small-cell lung cancer, and ND-646 and its derivatives as ACC1 inhibitors deserve further study for treatment of NSCLC.
