Design, synthesis and evaluation of N13-substituted evodiamine derivatives against human cancer cell lines was written by Song, Senchuan;Chen, Zhiyong;Li, Shaoxue;Huang, Yanmin;Wan, Yiqian;Song, Huacan. And the article was included in Molecules in 2013.Name: 1-Bromo-4-methoxybutane This article mentions the following:

Attempting to improve the anticancer activity and solubility of evodiamine in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF) solutions, thirty-eight N13-substituted evodiamine derivatives were designed, synthesized and tested for antitumor activity against six kinds of human cancer cell lines, namely prostate cancer (DU-145 and PC-3), lung cancer (H460), breast cancer (MCF-7), colon cancer (HCT-5) and glioblastoma (SF-268). The solubility of these compounds in SGF and SIF solutions was evaluated and apoptosis induced the title compounds was determined The results showed that among all compounds examined, several showed the highest antitumor activity and a broader spectrum of activity, with IC50 values ranging from 1-2 娓璏. Their solubility was obviously improved and several compounds had a significant impact inducing apoptosis in some cancer cell lines. The preliminary structure-activity relationships of these derivatives were discussed. The synthesis of the target compounds was achieved by alkylation of (13bS)-8,13,13b,14-tetrahydro-14-(methyl)indolo[2′,3′:3,4]pyrido[2,1-b]quinazolin-5(7H)-one (evodiamine) with alkylation agents, such as alkyl bromides. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4Name: 1-Bromo-4-methoxybutane).

1-Bromo-4-methoxybutane (cas: 4457-67-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Name: 1-Bromo-4-methoxybutane

Chemogenomic Profiling of Human and Microbial FK506-Binding Proteins was written by Pomplun, Sebastian;Sippel, Claudia;Haehle, Andreas;Tay, Donald;Shima, Kensuke;Klages, Alina;Uenal, Can Murat;Riess, Benedikt;Toh, Hui Ting;Hansen, Guido;Yoon, Ho Sup;Bracher, Andreas;Preiser, Peter;Rupp, Jan;Steinert, Michael;Hausch, Felix.

FK506-binding proteins (FKBPs) are evolutionarily conserved proteins that display peptidyl-prolyl isomerase activities and act as coreceptors for immunosuppressants. Microbial macrophage-infectivity-potentiator (Mip)-type FKBPs can enhance infectivity. However, developing druglike ligands for FKBPs or Mips has proven difficult, and many FKBPs and Mips still lack biol. useful ligands. To explore the scope and potential of C⁵-substituted [4.3.1]-aza-bicyclic sulfonamides as a broadly applicable class of FKBP inhibitors, we developed a new synthesis method for the bicyclic core scaffold and used it to prepare an FKBP- and Mip-focused library. This allowed us to perform a systematic structure-activity-relationship anal. across key human FKBPs and microbial Mips, yielding highly improved inhibitors for all the FKBPs studied. A cocrystal structure confirmed the mol.-binding mode of the core structure and explained the affinity gained as a result of the preferred substituents. The best FKBP and Mip ligands showed promising antimalarial, antileginonellal, and antichlamydial properties in cellular models of infectivity, suggesting that substituted [4.3.1]-aza-bicyclic sulfonamides could be a novel class of anti-infectives. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4HPLC of Formula: 4457-67-4).

Host-guest supramolecular amphiphile enhanced photodecomposition with responsive room-temperature phosphorescence signals was written by Li, Teng;Ma, Xiang. And the article was included in Dyes and Pigments in 2018.Recommanded Product: 4457-67-4 This article mentions the following:

Photolyzable matric belongs to photo-responsive system that experiences irreversible decomposition after irradiation While the self-aggregation of photosensitizers in aqueous media often results in lower photosensitizing ability. In this work, an enhanced photolyzable system is constructed through host-guest recognition between amphiphilic 6-bromoisoquinoline functionalized alkoxyanthracene (AnBq) and cucurbit[7]uril (CB[7]). In addition, a visible room-temperature phosphorescence (RTP) signal occurs along with the photolysis reaction as the suppression of intramol. photoinduced electron transfer (PET) process from the anthracene moiety to phosphorous 6-bromoisoquinoline moiety. The formation of the host-guest assembly and the photolysis of AnBq are clearly corroborated through UV-Vis, NMR and MS spectroscopy. This photo-responsive host-guest assembly provides some hints for the design of photodegradable materials.
