The growth factor receptor-bound protein 2 (Grb2) is an SH2 domain-containing docking module that represents an attractive target for anticancer therapeutic intervention. To improve the potency and bioavailability of the Grb2-SH2 inhibitors, the chiral alpha-methyl-alpha-carboxyalkyl amino acid [(alpha-Me)Aa] was designed to cover dual structural and functional features separately contributed by 1-aminocyclohexanecarboxylic acid (Ac6c) and alpha-aminoadipic acid (Adi) in position Y + 1. The enantiopure L(or D)-(alpha-Me)Aa bearing various chain length carboxylalkyl side chain was conveniently synthesized by an optimized oxazolidinone methodology. The incorporation of (S)-(alpha-Me)Aa into the non-pTyr-containing peptide framework with a 5-amino acid sequence binding motif of X-2-Leu- (3?-substituted-Tyr)0-X+1-Asn really improved the inhibitory activity, affording potent (R)-sulfoxide-bridged cyclic and an open-chain series of pentapeptide inhibitors of Grb2-SH2 domain (IC50 = 1.1-5.8 muM). More significantly, these (alpha-Me)Aa incorporated peptide inhibitors showed excellent activities in inhibiting the growth of erbB2-dependent MDA-MB-453 tumor cell lines with low micromolar IC50 values, owing to the reduced peptidic nature and absence of pTyr or pTyr mimetics.

An iridium photoredox catalyst in combination with either a stoichiometric amount of Br°nsted acid or a catalytic amount of Lewis acid is capable of catalyzing regioselective alkylation of N-heteroarenes with N-(acyloxy)phthalimides at room temperature under irradiation. A broad range of N-heteroarenes can be alkylated using a variety of secondary, tertiary, and quaternary carboxylates. Mechanistic studies suggest that an IrII/IrIIIredox catalytic cycle is responsible for the observed reactivity.

Highly enantioselective alkylation of protected glycine diphenylmethyl (Dpm) amide 1 and Weinreb amide 10 has been realized under phase-transfer conditions by the successful utilization of designer chiral quaternary ammonium salts of type 4 as catalyst. Particularly, remarkable reactivity of the chiral ammonium enolate derived from 1b and 4c allowed the reaction with less reactive simple secondary alkyl halides with high efficiency and enantioselectivity. An additional unique feature of this chiral ammonium enolate is its ability to recognize the chirality of beta-branched primary alkyl halides, which provides impressive levels of kinetic resolution and double stereodifferentiation during the alkylation, allowing for two alpha- and gamma-stereocenters to be controlled. Combined with the subsequent reduction using LiAlH4 in cyclopentyl methyl ether (CPME), this system offers a facile access to structurally diverse optically active vicinal diamines. Furthermore, the optically active alpha-amino acid Weinreb amide 11 can be efficiently converted to the corresponding amino ketone by a simple treatment with Grignard reagents. In addition, reduction and alkylation of the optically active alpha-amino ketone into both syn and anti alpha-amino alcohols with almost complete relative and absolute stereochemical control have been achieved. With (S,S)- and (R,R)-4 in hand, the present approach renders both enantiomers of alpha-amino amides including Weinreb amides readily available with enormous structural variation and also establishes a general and practical route to vicinal diamines, alpha-amino ketones, and alpha-amino alcohols with the desired stereochemistry.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 20375-65-9.Recommanded Product: 3-Phenyl-6-chloropyridazine

An efficient two-step synthesis of 3,6-diaminopyridazine from 3,6-dichloropyridazine is reported. In this synthetic procedure, 4-methoxybenzylamine was used as a nitrogen source to substitute the chloro groups of 3,6-dichloropyridazine to form N,N’-bis-(4-methoxybenzyl)-pyridazine- 3,6-diamine. The 4-methoxybenzyl groups were then removed by treatment with hydrochloric acid to provide the target 3,6-diaminopyridazine with an overall yield of 78%. Copyright Taylor & Francis Group, LLC.

Biocatalytic methods for peptide synthesis are of high value due to the rapidly increasing approval of peptide-based therapeutics and the need to develop new analogs. Guinea pig liver transglutaminase (gTG2) catalyzes the cross-linking of peptides and proteins via the formation of gamma-glutamyl-epsilon-lysyl isopeptide bonds. In this study, we investigate gTG2-catalyzed peptide bond formation between various amino acid-derived donor and acceptor substrates. Using LC-MS analysis, we demonstrate that gTG2 forms Gly-Xaa and d-Ala-Gly dipeptide products, confirming that its natural transamidation activity can be co-opted for peptide synthesis. An aromatic ester of Gly was the most efficient acyl-donor substrate tested; aromatic esters of d-Ala and l-Ala showed 50-fold lower reactivity or no reactivity, respectively. A computational strategy combining computational protein design algorithms and molecular dynamics simulations was developed to model the binding modes of donor substrates in the gTG2 active site. We show that the inability of gTG2 to efficiently catalyze peptide synthesis from donors containing alanine results from the narrow substrate binding tunnel, which prevents bulkier donors from adopting a catalytically productive binding mode. Our observations pave the way to future protein engineering efforts to expand the substrate scope of gTG2 in peptide synthesis, which may lead to useful biocatalysts for the synthesis of desirable bioactive molecules.

Safety of 5-Bromopyridazin-4-amine, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.55928-90-0, Name is 5-Bromopyridazin-4-amine, molecular formula is C4H4BrN3. In a Article，once mentioned of 55928-90-0

Synthesis and structure-activity relationship (SAR) of a series of nonsteroidal glucocorticoid receptor (GR) agonists are described. These compounds contain “diazaindole” moieties and display different transcriptional regulatory profiles in vitro and are considered “dissociated” between gene transrepression and transactivation. The lead optimization effort described in this article focused in particular on limiting the transactivation of genes which result in bone side effects and these were assessed in vitro in MG-63 osteosarcoma cells, leading to the identification of (R)-18 and (R)-21. These compounds maintained anti-inflammatory activity in vivo in collagen induced arthritis studies in mouse but had reduced effects on bone relevant parameters compared to the widely used synthetic glucocorticoid prednisolone 2 in vivo. To our knowledge, we are the first to report on selective glucocorticoid ligands with reduced bone loss in a preclinical in vivo model.

A novel diiridium complex [(N^C^N)2Ir(bis-N^C)Ir(N^C^N)2Cl]PF6 (N^C^N = 2-[3-tert-butyl-5-(pyridin-2-yl)phenyl]pyridine; bis-N^C = 3,6-bis(4-tert-butylphenyl)pyridazine) was designed, synthesised and characterised. The key feature of the complex is the bridging pyridazine ligand which brings two cyclometallated Ir(iii) metal centres close together so that Cl also acts as a bridging ligand leading to a cationic complex. The ionic nature of the complex offers a possibility of improving solubility in water. The complex displays broad emission in the red region (lambdaem = 520-720 nm, tau = 1.89 mus, Phiem = 62% in degassed acetonitrile). Cellular assays by multiphoton (lambdaex = 800 nm) and confocal (lambdaex = 405 nm) microscopy demonstrate that the complex enters cells and localises to the mitochondria, demonstrating cell permeability. Further, an appreciable yield of singlet oxygen generation (PhiDelta = 0.45, direct method, by 1O2 NIR emission in air equilibrated acetonitrile) suggests a possible future use in photodynamic therapy. However, the complex has relatively high dark toxicity (LD50 = 4.46 muM), which will likely hinder its clinical application. Despite this toxicity, the broad emission spectrum of the complex and high emission yield observed suggest a possible future use of this class of compound in emission bioimaging. The presence of two heavy atoms also increases the scattering of electrons, supporting potential future applications as a dual fluorescence and electron microscopy probe.
