On November 1, 2015, Larraufie, Marie-Helene; Yang, Wan Seok; Jiang, Elise; Thomas, Ajit G.; Slusher, Barbara S.; Stockwell, Brent R. published an article.Application In Synthesis of 5-Bromo-2-isopropoxyaniline The title of the article was Incorporation of metabolically stable ketones into a small molecule probe to increase potency and water solubility. And the article contained the following:

Introducing a reactive carbonyl to a scaffold that does not otherwise have an electrophilic functionality to create a reversible covalent inhibitor is a potentially useful strategy for enhancing compound potency. However, aldehydes are metabolically unstable, which precludes the use of this strategy for compounds to be tested in animal models or in human clin. studies. To overcome this limitation, the authors designed ketone-based functionalities capable of forming reversible covalent adducts, while displaying high metabolic stability, and imparting improved water solubility to their pendant scaffold. The authors tested this strategy on the ferroptosis inducer and exptl. therapeutic erastin, and observed substantial increases in compound potency. In particular, a new carbonyl erastin analog, termed IKE, displayed improved potency, solubility and metabolic stability, thus representing an ideal candidate for future in vivo cancer therapeutic applications. The experimental process involved the reaction of 5-Bromo-2-isopropoxyaniline(cas: 1019442-22-8).Application In Synthesis of 5-Bromo-2-isopropoxyaniline

On July 28, 2022, Grottelli, Silvia; Annunziato, Giannamaria; Pampalone, Gioena; Pieroni, Marco; Dindo, Mirco; Ferlenghi, Francesca; Costantino, Gabriele; Cellini, Barbara published an article.Recommanded Product: 4-(Bromomethyl)-1,1′-biphenyl The title of the article was Identification of Human Alanine-Glyoxylate Aminotransferase Ligands as Pharmacological Chaperones for Variants Associated with Primary Hyperoxaluria Type 1. And the article contained the following:

Primary hyperoxaluria type I (PH1) is a rare kidney disease due to the deficit of alanine:glyoxylate aminotransferase (AGT), a pyridoxal-5′-phosphate-dependent enzyme responsible for liver glyoxylate detoxification, which in turn prevents oxalate formation and precipitation as kidney stones. Many PH1-associated missense mutations cause AGT misfolding. Therefore, the use of pharmacol. chaperones (PCs), small mols. that promote correct folding, represents a useful therapeutic option. To identify ligands acting as PCs for AGT, we first performed a small screening of com. available compounds We tested each mol. by a dual approach aimed at defining the inhibition potency on purified proteins and the chaperone activity in cells expressing a misfolded variant associated with PH1. We then performed a chem. optimization campaign and tested the resulting synthetic mols. using the same approach. Overall, the results allowed us to identify a promising hit compound for AGT and draw conclusions about the requirements for optimal PC activity. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Recommanded Product: 4-(Bromomethyl)-1,1′-biphenyl

And the article contained the following:

The mitotic spindle is a microtubule-based machine that segregates a replicated set of chromosomes during cell division. Many cancer drugs alter or disrupt the microtubules that form the mitotic spindle. Microtubule-dependent mol. motors that function during mitosis are logical alternative mitotic targets for drug development. Eg5 (Kinesin-5) and Kif15 (Kinesin-12), in particular, are an attractive pair of motor proteins, as they work in concert to drive centrosome separation and promote spindle bipolarity. Furthermore, we hypothesize that the clin. failure of Eg5 inhibitors may be (in part) due to compensation by Kif15. In order to test this idea, we screened a small library of kinase inhibitors and identified GW108X, an oxindole that inhibits Kif15 in vitro. We show that GW108X has a distinct mechanism of action compared with a com. available Kif15 inhibitor, Kif15-IN-1 and may serve as a lead with which to further develop Kif15 inhibitors as clin. relevant agents. The experimental process involved the reaction of 3-Bromo-5-fluoro-4-hydroxybenzaldehyde(cas: 185345-46-4).Name: 3-Bromo-5-fluoro-4-hydroxybenzaldehyde

And the article contained the following:

Benzimidazole-based allosteric inhibitors of the hepatitis C virus (HCV) NS5B polymerase were diversified to a variety of topol. related scaffolds. Replacement of the polar benzimidazole core by lipophilic indoles led to inhibitors with improved potency in the cell-based subgenomic HCV replicon system. Transposing the indole scaffold into a previously described series of benzimidazole-tryptophan amides generated the most potent inhibitors of HCV RNA replication in cell culture reported to date in this series (EC50 ∼ 50 nM).

And the article contained the following:

Trypanosoma brucei (T. brucei) and Trypanosoma cruzi (T. cruzi) are causative agents of parasitic diseases known as human African trypanosomiasis and Chagas disease, resp. Together, these diseases affect 68 million people around the world. Current treatments are unsatisfactory, frequently associated with intolerable side-effects, and generally inadequate in treating all stages of disease. In this paper, we report the discovery of N-ethylurea pyrazoles that potently and selectively inhibit the viability of T. brucei and T. cruzi. Sharp and logical SAR led to the identification of 54 as the best compound, with an in vitro IC50 of 9 nM and 16 nM against T. b. brucei and T. cruzi, resp. Compound 54 demonstrates favorable physicochem. properties and was efficacious in a murine model of Chagas disease, leading to undetectable parasitemia within 6 days when CYP metabolism was inhibited. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Electric Literature of 574-98-1

And the article contained the following:

Many diseases are believed to be driven by pathol. levels of reactive oxygen species (ROS) and oxidative stress has long been recognized as a driver for inflammatory disorders. Apoptosis signal-regulating kinase 1 (ASK1) has been reported to be activated by intracellular ROS and its inhibition leads to a down regulation of p38-and JNK-dependent signaling. Consequently, ASK1 inhibitors may have the potential to treat clin. important inflammatory pathologies including renal, pulmonary and liver diseases. Anal. of the ASK1 ATP-binding site suggested that Gln756, an amino acid that rarely occurs at the GK+2 position, offered opportunities for achieving kinase selectivity for ASK1 which was applied to the design of a parallel medicinal chem. library that afforded inhibitors of ASK1 with nanomolar potency and excellent kinome selectivity. A focused optimization strategy utilizing structure-based design resulted in the identification of ASK1 inhibitors with low nanomolar potency in a cellular assay, high selectivity when tested against kinase and broad pharmacol. screening panels, and attractive physicochem. properties. The compounds we describe are attractive tool compounds to inform the therapeutic potential of ASK1 inhibition. The experimental process involved the reaction of Methyl 5-bromo-2-methoxy-4-methylbenzoate(cas: 39503-58-7).Computed Properties of 39503-58-7

And the article contained the following:

A 4-nitroimidazole isocyanide derivative (6) was synthesized and radiolabeled with 99mTc(CO)3 core in high yield. It was interesting to note that 99mTc(CO)3-6a and 99mTc(CO)3-6b can be prepared at 100 °C and 25 °C, resp. 99mTc(CO)3-6a had three 6 mols. while 99mTc(CO)3-6b contained two 6 mols. The corresponding rhenium complexes were prepared to confirm the structure of the 99mTc complexes. Both complexes showed good stability in vitro and hypoxic selectivity. The partition coefficient results indicated both of them were hydrophilic and 99mTc(CO)3-6a was more hydrophilic than 99mTc(CO)3-6b. From the biodistribution study results, 99mTc(CO)3-6a showed higher tumor/blood and tumor/muscle ratios at 2 h post-injection. Further, single photon emission computed tomog. (SPECT) imaging study of 99mTc(CO)3-6a showed there was an observable tumor uptake, suggesting it would be a potential tracer for imaging of tumor hypoxia.

K.; Bavo, Francesco; Loeffler, Rebekka; Damgaard, Maria; Ecker, Gerhard F.; Froelund, Bente; Wellendorph, Petrine published an article.COA of Formula: C13H11Br The title of the article was Exploring the molecular determinants for subtype-selectivity of 2-amino-1,4,5,6-tetrahydropyrimidine-5-carboxylic acid analogs as betaine/GABA transporter 1 (BGT1) substrate-inhibitors. And the article contained the following:

We have previously identified 2-amino-1,4,5,6-tetrahydropyrimidine-5-carboxylic acid (ATPCA) as the most potent substrate-inhibitor of the betaine/GABA transporter 1 (BGT1) (IC50 2.5 μM) reported to date. Herein, we characterize the binding mode of 20 novel analogs and propose the mol. determinants driving BGT1-selectivity. A series of N1-, exocyclic-N-, and C4-substituted analogs was synthesized and pharmacol. characterized in radioligand-based uptake assays at the four human GABA transporters (hGATs) recombinantly expressed in mammalian cells. Overall, the analogs retained subtype-selectivity for hBGT1, though with lower inhibitory activities (mid to high micromolar IC50 values) compared to ATPCA. Further characterization of five of these BGT1-active analogs in a fluorescence-based FMP assay revealed that the compounds are substrates for hBGT1, suggesting they interact with the orthosteric site of the transporter. In silico-guided mutagenesis experiments showed that the non-conserved residues Q299 and E52 in hBGT1 as well as the conformational flexibility of the compounds potentially contribute to the subtype-selectivity of ATPCA and its analogs. Overall, this study provides new insights into the mol. interactions governing the subtype-selectivity of BGT1 substrate-inhibitors. The findings may guide the rational design of BGT1-selective pharmacol. tool compounds for future drug discovery.

T. published an article.SDS of cas: 2567-29-5 The title of the article was Antitubercular and Antiparasitic 2-Nitroimidazopyrazinones with Improved Potency and Solubility. And the article contained the following:

Following the approval of delamanid and pretomanid as new drugs to treat drug-resistant tuberculosis, there is now a renewed interest in bicyclic nitroimidazole scaffolds as a source of therapeutics against infectious diseases. We recently described a nitroimidazopyrazinone bicyclic subclass with promising antitubercular and antiparasitic activity, prompting addnl. efforts to generate analogs with improved solubility and enhanced potency. The key pendant aryl substituent was modified by (i) introducing polar functionality to the methylene linker, (ii) replacing the terminal Ph group with less lipophilic heterocycles, or (iii) generating extended biaryl side chains. Improved antitubercular and antitrypanosomal activity was observed with the biaryl side chains, with most analogs achieved 2- to 175-fold higher activity than the monoaryl parent compounds, with encouraging improvements in solubility when pyridyl groups were incorporated. This study has contributed to understanding the existing structure-activity relationship (SAR) of the nitroimidazopyrazinone scaffold against a panel of disease-causing organisms to support future lead optimization.
