And the article was included in Letters in Drug Design & Discovery in 2020.COA of Formula: C13H14BrNO2 This article mentions the following:

Due to the complex etiol. of AD, multi-target-directed ligands (MTDLs), combining two or more distinct pharmacol. moieties, have been developed in both symptomatic and disease-modifying efficiencies and are considered as an effective way for the treatment of AD. To test their biol. activities, including AChE/BChE inhibitory activity and MAOA/ MAO-B inhibitory activity. In addition, mol. modeling studies were performed to afford insight into the binding mode. The results displayed that compound 4c showed the best AChE inhibitory activity with an IC₅₀ value of 4.2 I1/4M, which was supported by the kinetic study and docking study. Compound 4c was also a selective MAO-B inhibitor (IC₅₀ = 8.2 I1/4M). Moreover, compound 4c could cross the blood-brain barrier in vitro. Compound 4c deserved to further study as a potential multifunctional agent for the treatment of Alzheimeraeuros disease. In the experiment, the researchers used many compounds, for example, N-(5-Bromopentyl)phthalimide (cas: 954-81-4COA of Formula: C13H14BrNO2).

N-(5-Bromopentyl)phthalimide (cas: 954-81-4) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon閳ユ彽romine bond is electrophilic, i.e. alkyl bromides are alkylating agents. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.COA of Formula: C13H14BrNO2

Synthesis and evaluation of the performance of a small molecule library based on diverse tropane-related scaffolds was written by Lowe, Robert A.;Taylor, Dale;Chibale, Kelly;Nelson, Adam;Marsden, Stephen P.. And the article was included in Bioorganic & Medicinal Chemistry in 2020.Application of 61150-57-0 This article mentions the following:

A unified synthetic approach was developed that enabled the synthesis of diverse tropane-related scaffolds. The key intermediates that were exploited were cycloadducts formed by reaction between 3-hydroxypyridinium salts and vinyl sulfones or sulfonamides. The diverse tropane-related scaffolds were formed by addition of substituents to, cyclization reactions of, and fusion of addnl. ring(s) to the key bicyclic intermediates. A set of 53 screening compounds was designed, synthesized and evaluated in order to determine the biol. relevance of the scaffolds accessible using the synthetic approach. Two inhibitors of Hedgehog signalling, and four compounds with weak activity against the parasite P. falciparum, were discovered. Three of the active compounds may be considered to be indotropane or pyrrotropane pseudo natural products in which a tropane is fused with a fragment from another natural product class. It was concluded that the unified synthetic approach had yielded diverse scaffolds suitable for the design of performance-diverse screening libraries.

Design, Synthesis, and Biological Activity of Substrate Competitive SMYD2 Inhibitors was written by Cowen, Scott D.;Russell, Daniel;Dakin, Leslie A.;Chen, Huawei;Larsen, Nicholas A.;Godin, Robert;Throner, Scott;Zheng, Xiaolan;Molina, Audrey;Wu, Jiaquan;Cheung, Tony;Howard, Tina;Garcia-Arenas, Renee;Keen, Nicholas;Pendleton, Christopher S.;Pietenpol, Jennifer A.;Ferguson, Andrew D.. And the article was included in Journal of Medicinal Chemistry in 2016.Application In Synthesis of 1-(2-Bromoethyl)-4-methoxybenzene This article mentions the following:

Protein lysine methyltransferases (KMTs) have emerged as important regulators of epigenetic signaling. These enzymes catalyze the transfer of donor Me groups from the cofactor S-adenosylmethionine to specific acceptor lysine residues on histones, leading to changes in chromatin structure and transcriptional regulation. These enzymes also methylate an array of non-histone proteins, suggesting addnl. mechanisms by which they influence cellular physiol. SMYD2 is reported to be an oncogenic methyltransferase that represses the functional activity of the tumor suppressor proteins p53 and RB. HTS screening led to identification of five distinct substrate-competitive chem. series, e.g., I (X = C, R¹ = H, CN, OMe; X = N, R¹ = H, OMe, NHMe). Determination of liganded crystal structures of SMYD2 contributed significantly to ‘hit-to-lead’ design efforts, culminating in the creation of potent and selective inhibitors that were used to understand the functional consequences of SMYD2 inhibition. Taken together these results have broad implications for inhibitor design against KMTs, and clearly demonstrate the potential for developing novel therapies against these enzymes. In the experiment, the researchers used many compounds, for example, 1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0Application In Synthesis of 1-(2-Bromoethyl)-4-methoxybenzene).

Novel acetylenyl-containing benzamide derivatives were synthesized and screened using an in vitro assay measuring increases in glucokinase activity stimulated by 10 mM glucose concentration and glucose uptake in rat hepatocytes. Lead optimization of an acetylenyl benzamide series led to the discovery of several active compounds via in vitro enzyme assays (EC₅₀ < 40 nM) and in vivo OGTT assays (AUC reduction > 40% at 50 mg/kg). Of the active compounds tested, 3-(3-amino-phenylethynyl)-5-(2-methoxy-1-methyl-ethoxy)-N-(1-methyl-1H-pyrazol-3-yl)-benzamide I was identified as a potent glucokinase activator exhibiting an EC₅₀ of 27 nM and eliciting a 2.16-fold increase in glucose uptake. Compound I caused a glucose AUC reduction of 47.4% (30 mg/kg) in an OGTT study in C57BL/6J mice compared to 22.6% for sitagliptin (30 mg/kg).
