Attachment of cationic moieties to oligonucleotides (ONs) promises not only to increase the binding affinity of antisense ONs by reducing charge repulsion between the two neg. charged strands of a duplex, but also to augment their in vivo stability against nucleases. In this study, polyamine functionality was introduced into ONs by means of 2閳?amino-LNA scaffolds. The resulting ONs exhibited efficient binding towards ssDNA, ssRNA and dsDNA targets, and the 2閳?amino-LNA analog carrying a tri-aminated linker showed the most pronounced duplex- and triplex-stabilizing effect. Mol. modeling revealed that favorable conformational and electrostatic effects led to salt-bridge formation between pos. charged polyamine moieties and the Watson-Hoogsteen groove of the dsDNA targets, resulting in the observed triplex stabilization. All the investigated monomers showed increased resistance against 3閳?nucleolytic digestion relative to the non-functionalized controls. In the experiment, the researchers used many compounds, for example, N-(5-Bromopentyl)phthalimide (cas: 954-81-4Recommanded Product: 954-81-4).

N-(5-Bromopentyl)phthalimide (cas: 954-81-4) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Recommanded Product: 954-81-4

Structure-activity relationship study of hypoxia-activated prodrugs for proteoglycan-targeted chemotherapy in chondrosarcoma was written by Ghedira, Donia;Voissiere, Aurelien;Peyrode, Caroline;Kraiem, Jamil;Gerard, Yvain;Maubert, Elise;Vivier, Magali;Miot-Noirault, Elisabeth;Chezal, Jean-Michel;Farhat, Farhat;Weber, Valerie. And the article was included in European Journal of Medicinal Chemistry in 2018.SDS of cas: 954-81-4 This article mentions the following:

Due to an abundant chondrogenic, poorly vascularized and particularly hypoxic extracellular matrix, chondrosarcoma, a malignant cartilaginous tumor, is chemo- and radio-resistant. Surgical resection with wide margins remains the mainstay of treatment. To address the lack of therapy, our strategy aims to increase anticancer drugs targeting and delivery in the tumor, by leveraging specific chondrosarcoma hallmarks: an extensive cartilaginous extracellular matrix, namely the high neg. fixed charge d. and severe chronic hypoxia. A dual targeted therapy for chondrosarcoma was investigated by conjugation of a hypoxia-activated prodrug (HAP) to quaternary ammonium (QA) functions which exhibit a high affinity for polyanionic sites of proteoglycans (PGs), the major components of the chondrosarcoma extracellular matrix. Based on preclin. results, an imidazole prodrug, ICF05016, was identified and provided the basis for a lead optimization study. A series of 27 QA-phosphoramide mustard conjugates, differing by the type of QA function and the length of the alkyl linker, was yielded by a common multi-step sequence involving phosphorylation of a key 2-nitroimidazole alc. Then, a screening was realized by surface plasmon resonance technol. to assess biomol. interactions between QA derivatives and aggrecan, the most abundant PG in chondrosarcoma. Results revealed that affinity depends more on the type of QA function, than on the linker length. Moreover, the presence of a benzyl group enhanced affinity to aggrecan. Twelve compounds were shortlisted and evaluated for antiproliferative activity (i.e., growth inhibiting concentration 50), under normoxic and hypoxic conditions using the human extraskeletal myeloid chondrosarcoma cell line (HEMC-SS). For all prodrugs, hypoxic selectivity was maintained and even increased, compared with the lead. From this study, compound I emerged as the most effective PG-targeted HAPs with a dissociation constant of 2.10 娓璏 in the SPR experiment, a hypoxia cytotoxicity ratio of 24 and an efficient reductive cleavage under chem. and enzymic conditions. In the experiment, the researchers used many compounds, for example, N-(5-Bromopentyl)phthalimide (cas: 954-81-4SDS of cas: 954-81-4).

N-(5-Bromopentyl)phthalimide (cas: 954-81-4) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar.

Chemo-proteomics exploration of HDAC degradability by small molecule degraders was written by Xiong, Yuan;Donovan, Katherine A.;Eleuteri, Nicholas A.;Kirmani, Nadia;Yue, Hong;Razov, Anthony;Krupnick, Noah M.;Nowak, Radoslaw P.;Fischer, Eric S..

Targeted protein degradation refers to the use of small mols. that recruit a ubiquitin ligase to a target protein for ubiquitination and subsequent proteasome-dependent degradation While degraders have been developed for many targets, key questions regarding degrader development and the consequences of acute pharmacol. degradation remain, specifically for targets that exist in obligate multi-protein complexes. Here, we synthesize a pan-histone deacetylase (HDAC) degrader library for the chemo-proteomic exploration of acute degradation of a key class of chromatin-modifying enzymes. Using chemo-proteomics, we not only map the degradability of the zinc-dependent HDAC family identifying leads for targeting HDACs 1-8 and 10 but also explore important aspects of degrading epigenetic enzymes. We discover cell line-driven target specificity and that HDAC degradation often results in collateral loss of HDAC-containing repressive complexes. These findings potentially offer a new mechanism toward controlling chromatin structure, and our resource will facilitate accelerated degrader design and development for HDACs.

N-Phthalimidoalkyl derivatives of 2灏?carbomethoxy-3灏?(4′-iodophenyl)tropane (灏?CIT): brain monoamine transporter affinity was written by Tamagnan, Gilles;Neumeyer, John L.;Gao, Yigong;Wang, Shaoyin;Kula Nora;Baldessarini, Ross J..

A series of novel N-phthalimidoalkyl analogs I (n = 2-5, 8) for the stable phenyltropane 灏?CIT were synthesized and evaluated by selective radioligand binding assays for affinity to transporters for dopamine (DA), serotonin (5-HT) and norepinephrine (NE) in corpus striatum tissue from rat forebrain. 灏?CIT and I (n = 4, 5, 8) showed similarly greater affinity at 5-HT than DA transporters; this affinity was lost with I (n = 2, 3). These results are consistent with interference at a critical binding site for the tropane nitrogen on the transporter proteins and indicate that the tropane nitrogen atom can be substituted with large substituted alkyl moieties without loss of affinity or selectivity for amine transporters.

Design and Synthesis of [(2,3-Dichlorophenyl)piperazin-1-yl]alkylfluorenylcarboxamides as Novel Ligands Selective for the Dopamine D₃ Receptor Subtype was written by Robarge, Michael J.;Husbands, Stephen M.;Kieltyka, Andrzej;Brodbeck, Robbin;Thurkauf, Andrew;Newman, Amy Hauck. And the article was included in Journal of Medicinal Chemistry in 2001.HPLC of Formula: 954-81-4 This article mentions the following:

The dopamine D₃ receptor subtype has been recently targeted as a potential neurochem. modulator of the behavioral actions of psychomotor stimulants, such as cocaine. However, definitive behavioral investigations have been hampered by the lack of highly selective D₃ agonists and antagonists. In an attempt to design a novel class of D₃ ligands with which to study this receptor system, a series of chem. divergent compounds that possessed various structural features that exist within several classes of reputed D₃ agents was screened and compared to the recently reported NGB 2904. On the basis of these results, a novel series of compounds was designed that included functional moieties that were required for high-affinity and selective binding to D₃ receptors. All the compounds in this series included an aryl-substituted piperazine ring, a varying alkyl chain linker (C₃-C₅), and a terminal aryl amide. The compounds were synthesized and evaluated in vitro for binding in CHO cells transfected with human D₂, D₃, or D₄ receptor cDNAs. D₃ binding affinities ranged from K_i = 1.4 to 1460 nM. The most potent analog in this series, I, demonstrated a D₃/D₂ selectivity of 64 and a D₃/D₄ selectivity of 1300. Structure-activity relationships for this class of ligands at D₃ receptors will provide new leads toward the development of highly selective and potent mol. probes that will prove useful in the elucidation of the role D₃ receptors play in the psychomotor stimulant and reinforcing properties of cocaine.

5-HT₄ receptor agonists such as tegaserod have demonstrated efficacy in the treatment of constipation predominant irritable bowel syndrome (IBS-C), a highly prevalent disorder characterized by chronic constipation and impairment of intestinal propulsion, abdominal bloating, and pain. The 5-HT₄ receptor binding site can accommodate functionally and sterically diverse groups attached to the amine nitrogen atom of common ligands, occupying what may be termed a “secondary” binding site. Using a multivalent approach to lead discovery, the effects of varying the position and nature of the secondary binding group were investigated as a strategy to achieve the desired 5-HT₄ agonist pharmacol. profile. It was shown that the ability of amine-based secondary binding groups to impart exceptional gains in the binding affinity, selectivity, and functional potency of 5-HT₄ agonists. Optimization of the leads generated by this approach afforded compound I, a selective, orally efficacious 5-HT₄ agonist for the potential treatment of gastrointestinal motility-related disorders.

Due to the complex nature of Alzheimer’s disease, multi-target-directed ligand approaches are one of the most promising strategies in the search for effective treatments. Acetylcholinesterase, butyrylcholinesterase and 灏?amyloid are the predominant biol. targets in the search for new anti-Alzheimer’s agents. Our aim was to combine both anticholinesterase and 灏?amyloid anti-aggregation activities in one mol., and to determine the therapeutic potential in vivo. We designed and synthesized 28 new compounds as derivatives of donepezil that contain the N-benzylpiperidine moiety combined with the phthalimide or indole moieties. Most of these test compounds showed micromolar activities against cholinesterases and aggregation of 灏?amyloid, combined with pos. results in blood-brain barrier permeability assays. The most promising compound 23 (2-(8-(1-(3-chlorobenzyl)piperidin-4-ylamino)octyl)isoindoline-1,3-dione) is an inhibitor of butyrylcholinesterase (IC₅₀ = 0.72 娓璏) that has 灏?amyloid anti-aggregation activity (72.5% inhibition at 10 娓璏) and can cross the blood-brain barrier. Moreover, in an animal model of memory impairment induced by scopolamine, the activity of 23 was comparable to that of donepezil. The selected compound 23 is an excellent lead structure in the further search for new anti-Alzheimer’s agents.
