The title of the article was 《Identification of novel drug-resistant EGFR mutant inhibitors by in silico screening using comprehensive assessments of protein structures》.Recommanded Product: 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine The author mentioned the following in the article:

EGFR is a target protein for the treatment of non small cell lung cancer (NSCLC). The mutations associated with the activation of EGFR kinase activity, such as L858R and G719S, destabilize the inactive conformation of EGFR and are closely linked with the development of NSCLC. The addnl. T790M mutation reportedly causes drug resistance against the com. available EGFR inhibitors, gefitinib and erlotinib. In this study, we searched for novel G719S/T790M EGFR inhibitors by a new in silico screening strategy, using two datasets. The results of in silico screening using protein-ligand docking are affected by the selection of 3D structure of the target protein. As the first strategy, we chose the 3D structures for in silico screening by test dockings using the G719S/T790M crystal structure, its mol. dynamics snapshots, and known inhibitors of the drug-resistant EGFR. In the second strategy, we selected the 3D structures by test dockings using all of the EGFR structures, regardless of the mutations, and all of the known EGFR inhibitors. Using each of the 3D structures selected by the strategies, 1000 compounds were chosen from the 71,588 compounds Kinase assays identified 15 G719S/T790M EGFR inhibitors, including two compounds with novel scaffolds. Analyses of their structure-activity relationships revealed that interactions with the mutated Met790 residue specifically increase the inhibitory activity against G719S/T790M EGFR.

Alvarez de Cienfuegos, Luis; Mota, Antonio J.; Rodriguez, Concepcion; Robles, Rafael published an article on January 17 ,2005. The article was titled 《Highly efficient synthesis of 2′,3′-didehydro-2′,3′-dideoxy-β-nucleosides through a sulfur-mediated reductive 2′,3′-trans-elimination. From iodomethylcyclopropanes to thiirane analogs》, and you may find the article in Tetrahedron Letters.Electric Literature of C17H16N2O5 The information in the text is summarized as follows:

Taking into account the thiophilic properties of iodine, a very simple methodol. to achieve 2′,3′-didehydro-2′,3′-dideoxy-β-nucleosides in high yield was performed, using mild, and inexpensive conditions, by means of the treatment of 2′-deoxy-3′,5′-dibenzoyl-2′-iodo-β-nucleoside derivatives with NaHS. The process has shown to be highly dependent of the relative geometry between the iodine atom and the adjacent leaving group. In this way, different essays carried out with pyranose derivatives have concluded in no reaction when the vicinal groups to eliminate do not adopt a trans-diaxial disposition. In addition, the treatment of 2-iodomethyl-cyclopropane-1,1-dicarboxylic acid di-Et ester under the same conditions softly and readily leads to the obtention of a mixture of the expected 2-allyl-malonic acid di-Et ester (as the minor product) and the thiirane derivative 2-thiiranylmethyl-malonic acid di-Et ester (as the major product). In this case, the responsible of the reaction progress are the nucleophilic properties of the sulfur atom rather than the thiophilic character of the iodine atom. The results came from multiple reactions, including the reaction of ((2S,5R)-5-(5-Methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-2,5-dihydrofuran-2-yl)methyl benzoate(cas: 122567-97-9Electric Literature of C17H16N2O5)

The article was 《7-cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d] pyrimidin-4-ylamine inhibits the proliferation and migration of vascular smooth muscle cells by suppressing ERK and Akt pathways》. The article mentions the following:

Excessive vascular smooth muscle cell (VSMC) proliferation and migration after vascular injury significantly contributes to the development of occlusive vascular disease. Therefore, inhibiting the proliferation and migration of VSMCs is a validated therapeutic modality for occlusive vascular disease such as atherosclerosis and restenosis. In the present study, we screened chem. compounds for their anti-proliferative effects on VSMCs using multiple approaches, such as MTT assays, wound healing assays, and trans-well migration assays. Our data indicate that 7-cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d] pyrimidin-4-ylamine, a lymphocyte-specific protein tyrosine kinase (Lck) inhibitor, significantly inhibited both VSMC proliferation and migration. 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine suppresses VSMC proliferation and migration via down-regulating the protein kinase B (Akt) and extracellular signal regulated kinase (ERK) pathways, and it significantly decreased the expression of proliferating cell nuclear antigen (PCNA) and cyclin D1 and, the phosphorylation of retinoblastoma protein (pRb). Addnl., 7-cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d] pyrimidin-4-ylamine suppressed the migration of VSMCs from endothelium-removed aortic rings, as well as neointima formation following rat carotid balloon injury. The present study identified 7-cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine as a potent VSMC proliferation and migration inhibitor and warrants further studies to elucidate its more detailed mol. mechanisms, such as its primary target, and to further validate its in vivo efficacy as a therapeutic agent for pathol. vascular conditions, such as restenosis and atherosclerosis. In the part of experimental materials, we found many familiar compounds, such as 7-Cyclopentyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine(cas: 213743-31-8Related Products of 213743-31-8)

M.; Cano, Celine. The article conveys some information:

The nonclassical extracellular signal-related kinase 5 (ERK5) mitogen-activated protein kinase pathway has been implicated in increased cellular proliferation, migration, survival, and angiogenesis; hence, ERK5 inhibition may be an attractive approach for cancer treatment. However, the development of selective ERK5 inhibitors has been challenging. Previously, we described the development of a pyrrole carboxamide high-throughput screening hit into a selective, submicromolar inhibitor of ERK5 kinase activity. Improvement in the ERK5 potency was necessary for the identification of a tool ERK5 inhibitor for target validation studies. Herein, we describe the optimization of this series to identify nanomolar pyrrole carboxamide inhibitors of ERK5 incorporating a basic center, which suffered from poor oral bioavailability. Parallel optimization of potency and in vitro pharmacokinetic parameters led to the identification of a nonbasic pyrazole analog with an optimal balance of ERK5 inhibition and oral exposure. In the experiment, the researchers used 2-Methoxy-5-nitropyrimidine(cas: 14001-69-5Related Products of 14001-69-5)

And the article was published in European Journal of Medicinal Chemistry in 2019. Category: pyrimidines The author mentioned the following in the article:

Constitutive activation of MAPK (RAS/RAF/MEK/ERK) pathway is frequently observed in many tumors and thus has become an interesting therapeutic target for cancer therapy. Despite the successful development of BRAF and MEK inhibitors in clinic treatment, resistance often appears to re-enhance ERK1/2 signaling. Inspired by the central role of the ERK1/2 signaling cascade in cancer, we describe the scaffold-hopping generation of a series of isoindolin-1-one ERK1/2 inhibitors. Our new compounds could inhibit proliferation of KRAS and BRAF mutant cells lines at low nanomolar concentrations Compound 22a possesses acceptable pharmacokinetic profiles and showed considerable in vivo antitumor efficacy in a HCT-116 xenograft model, providing a promising basis for further optimization towards clin.
