Related Products of 144060-98-0. The article was titled 《Application of Fragment-Based Screening to the Design of Inhibitors of Escherichia coli DsbA》. The information in the text is summarized as follows:

The thiol-disulfide oxidoreductase enzyme DsbA catalyzes the formation of disulfide bonds in the periplasm of Gram-neg. bacteria. DsbA substrates include proteins involved in bacterial virulence. In the absence of DsbA, many of these proteins do not fold correctly, which renders the bacteria avirulent. Thus DsbA is a critical mediator of virulence and inhibitors may act as antivirulence agents. Biophys. screening has been employed to identify fragments that bind to DsbA from Escherichia coli. Elaboration of one of these fragments produced compounds that inhibit DsbA activity in vitro. In cell-based assays, the compounds inhibit bacterial motility, but have no effect on growth in liquid culture, which is consistent with selective inhibition of DsbA. Crystal structures of inhibitors bound to DsbA indicate that they bind adjacent to the active site. Together, the data suggest that DsbA may be amenable to the development of novel antibacterial compounds that act by inhibiting bacterial virulence.4-Methyl-2-(pyridin-4-yl)thiazole-5-carboxylic acid(cas: 144060-98-0Related Products of 144060-98-0) was used in this study.

Most of the compounds I showed satisfactory activity compared with lead compound foretinib. Among them, the most promising compound I (R = 1-(4-chlorophenyl)-5-(trifluoromethyl)-1H-pyrazol-4-yl, R1 = Me; X = F) (II) exhibited excellent antiproliferative activities against A549, MCF-7, and Hela cancer cell lines with IC50 values of 0.98 ± 0.08, 1.05 ± 0.17, and 1.28 ± 0.25μM, resp., as well as excellent kinase inhibitory activities (c-Met IC50 = 26.00 nM and VEGFR-2 IC50 = 2.6μM). Moreover, compound II inhibited the growth of A549 cells in G0/G1 phase in a dose-dependent manner, and induced the late apoptosis of A549 cells. Its intervention on intracellular c-Met signaling of A549 was verified by the result of Western blot. Fluorescence quant. PCR showed that compound 17l inhibited the growth of A549 cells by inhibiting the expression of c-Met and VEGFR-2, and its hemolytic toxicity was low. Mol. docking and mol. dynamics simulation indicated that compound II could bind to c-Met and VEGFR-2 protein, which was similar to that of foretinib.

The title of the article was 《A comparative study of fragment screening methods on the p38α kinase: new methods, new insights》.Application In Synthesis of 6-Morpholinobenzo[d]thiazol-2-amine The author mentioned the following in the article:

The stress-activated kinase p38α was used to evaluate a fragment-based drug discovery approach using the BioFocus fragment library. Compounds were screened by surface plasmon resonance (SPR) on a Biacore T100 against p38α and two selectivity targets. A sub-set of the library was the focus of detailed follow-up analyses that included hit confirmation, affinity determination on 24 confirmed, selective hits and competition assays of these hits with respect to a known ATP binding site inhibitor. In addition, functional activity against p38α was assessed in a biochem. assay using a mobility shift platform (LC3000, Caliper LifeSciences). A selection of fragments was also evaluated using fluorescence lifetime (FLEXYTE) and microscale thermophoresis (Nanotemper) technologies. A good correlation between the data for the different assays was found. Crystal structures were solved for four of the small mols. complexed to p38α. Interestingly, as determined both by X-ray anal. and SPR competition experiments, three of the complexes involved the fragment at the ATP binding site, while the fourth compound bound in a distal site that may offer potential as a novel drug target site. A first round of optimization around the remotely bound fragment has led to the identification of a series of triazole-containing compounds This approach could form the basis for developing novel and active p38α inhibitors. More broadly, it illustrates the power of combining a range of biophys. and biochem. techniques to the discovery of fragments that facilitate the development of novel modulators of kinase and other drug targets.6-Morpholinobenzo[d]thiazol-2-amine(cas: 94641-22-2Application In Synthesis of 6-Morpholinobenzo[d]thiazol-2-amine) was used in this study.

In 2020,European Journal of Organic Chemistry included an article by Rathnayake, Manjula D.; Weaver, Jimmie D.. HPLC of Formula: 3622-40-0. The article was titled 《A General Photocatalytic Route to Prenylation》. The information in the text is summarized as follows:

Prenylation is an essential reaction on which nature relies to modify properties of mols. and build terpenoids, but remains a challenging chem. reaction. Aiming to capitalize on recent advances in photocatalysis to easily and cleanly generate a broad range of carbon-based radicals, we have developed a prenyl transfer reagent, PhSO2C(Me)2CH:CH2, that is captured by transiently generated radicals. The reagent can be made in bulk, is bench stable, and broadly applicable such that it can be used with existing photocatalytic methods with very few changes to reaction conditions. Ultimately, this provides a true drop-in solution for prenylation, expanding the scope of substrates that can be readily prenylated.
