Synthesis, biological screening and molecular docking studies of some ethylated sulfonamides having 1,4-Benzodioxane moiety

The presented study comprises the synthesis of a new series of ethylated sulfonamides in which 1,4- benzodioxane moietyhas been incorporated. The reaction of 1,4-benzodioxane-6-amine (1) with ethane sulfonyl chloride (2) yielded N-(2,3-dihydrobenzo[1,4]dioxin-6-yl)ethanesulfonamide (3), which further on treatment with various alkyl/aralkyl halides, 4a-r, in N,N?-dimethylformamide (DMF) and in the presence of lithium hydride (LiH) acting as a weak base and catalyst;yielded derivativesofN-alkyl/aralkyl substituted N-(2,3-dihydrobenzo[1,4]dioxin-6- yl)ethanesulfonamides (5a-r). The characterization of these derivatives was carried out by different spectroscopic techniques like infra red, proton-NMR and mass spectrometry; then screened against various enzymes i.e. acetylcholinesterase, butyrylcholinesterase, lipoxygenase and alpha-glucosidase enzymes and five different bacterial strains. The synthesized compounds were found to be good inhibitors of lipoxygenase but moderate inhibitors of AChE, BChE and a-glucosidase; whereas compounds 3, 5a, 5f, 5n and 5r were found good antibacterial compounds. The interaction between inhibitors and target enzymes (cholinestrases and lipoxygenase) was computationally observed which correlated with the experimental results.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 22013-33-8, you can also check out more blogs about22013-33-8

Discovery and preclinical evaluation of a novel class of cytotoxic propynoic acid carbamoyl methyl amides (PACMAs)

Herein, we discovered a series of propynoic acid carbamoyl methyl-amides (PACMAs) with potent cytotoxicity against a panel of cancer cell lines. These compounds interrupted cell cycle progression at low micromolar concentrations and induced early and late stage apoptosis. A representative compound suppressed tumor growth without apparent toxicity in an MDA-MB-435 mouse xenograft model. We used a Kinexus 628-antibody microarray and the Ingenuity Pathway Analysis (IPA) bioinformatics tools to better understand their mechanisms. The IPA analysis revealed the initiation of Nrf2-mediated oxidative stress through modulating the expression of SOD1 and STIP1 by compound 1. The involvement of the oxidative stress pathway was further validated by measuring the levels of the PACMA-induced mitochondrial superoxide species. To our knowledge, this is the first report on the discovery and biological evaluations of PACMAs as anticancer agents. Their broad-spectrum in vitro cytotoxicity, possibly through an oxidative stress-mediated pathway, and in vivo efficacy warrant further preclinical investigations.

Synthesis and in vitro pharmacology of substituted quinoline-2,4-dicarboxylic acids as inhibitors of vesicular glutamate transport

The vesicular glutamate transport (VGLUT) system selectively mediates the uptake of L-glutamate into synaptic vesicles. Uptake is linked to an H+-ATPase that provides coupling among ATP hydrolysis, an electrochemical proton gradient, and glutamate transport. Substituted quinoline-2,4-dicarboxylic acids (QDCs), prepared by condensation of dimethyl ketoglutaconate (DKG) with substituted anilines and subsequent hydrolysis, were investigated as potential VGLUT inhibitors in synaptic vesicles. A brief panel of substituted QDCs was previously reported (Carrigan et al. Bioorg. Med. Chem. Lett. 1999, 9, 2607-2612)1 and showed that certain substituents led to more potent competitive inhibitors of VGLUT. Using these compounds as leads, an expanded series of QDC analogues were prepared either by condensation of DKG with novel anilines or via aryl-coupling (Suzuki or Heck) to dimethyl 6-bromoquinolinedicarboxylate. From the panel of almost 50 substituted QDCs tested as inhibitors of the VGLUT system, the 6-PhCH=CH-QDC (Ki = 167 muM), 6-PhCH2CH2-QDC (Ki = 143 muM), 6-(4?-phenylstyryl)-QDC (Ki = 64 muM), and 6-biphenyl-4-yl-QDC (Ki=41 muM) were found to be the most potent blockers. A preliminary assessment of the key elements needed for binding to the VGLUT protein based on the structure-activity relationships for the panel of substituted QDCs is discussed herein. The substituted QDCs represent the first synthetically derived VGLUT inhibitors and are promising templates for the development of selective transporter inhibitors.

Synthesis, molecular docking and biological evaluation of N,N-disubstituted 2-aminothiazolines as a new class of butyrylcholinesterase and carboxylesterase inhibitors

A series of 31 N,N-disubstituted 2-amino-5-halomethyl-2-thiazolines was designed, synthesized, and evaluated for inhibitory potential against acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and carboxylesterase (CaE). The compounds did not inhibit AChE; the most active compounds inhibited BChE and CaE with IC50 values of 0.22-2.3 muM. Pyridine-containing compounds were more selective toward BChE; compounds with the para-OMe substituent in one of the two dibenzyl fragments were more selective toward CaE. Iodinated derivatives were more effective BChE inhibitors than brominated ones, while there was no influence of halogen type on CaE inhibition. Inhibition kinetics for the 9 most active compounds indicated non-competitive inhibition of CaE and varied mechanisms (competitive, non-competitive, or mixed-type) for inhibition of BChE. Docking simulations predicted key binding interactions of compounds with BChE and CaE and revealed that the best docked positions in BChE were at the bottom of the gorge in close proximity to the catalytic residues in the active site. In contrast, the best binding positions for CaE were clustered rather far from the active site at the top of the gorge. Thus, the docking results provided insight into differences in kinetic mechanisms and inhibitor activities of the tested compounds. A cytotoxicity test using the MTT assay showed that within solubility limits (<30 muM), none of the tested compounds significantly affected viability of human fetal mesenchymal stem cells. The results indicate that a new series of N,N-disubstituted 2-aminothiazolines could serve as BChE and CaE inhibitors for potential medicinal applications.

Evaluation of a focused virtual library of heterobifunctional ligands for Clostridium difficile toxins

A focused library of virtual heterobifunctional ligands was generated in silico and a set of ligands with recombined fragments was synthesized and evaluated for binding to Clostridium difficile toxins. The position of the trisaccharide fragment was used as a reference for filtering docked poses during virtual screening to match the trisaccharide ligand in a crystal structure. The peptoid, a diversity fragment probing the protein surface area adjacent to a known binding site, was generated by a multi-component Ugi reaction. Our approach combines modular fragment-based design with in silico screening of synthetically feasible compounds and lays the groundwork for future efforts in development of composite bifunctional ligands for large clostridial toxins.

Iodine Catalysed Synthesis of Luminescent beta-Carboline Tethered Thiazolo[4,5-c]carbazole and Naphtho[2,1-d]thiazole Derivatives and Estimation of their Light Emitting Properties

A Simple, convenient and highly efficient I2-catalysed approach has been unfolded towards the synthesis of highly fluorescent beta-carboline C-1(3)-tethered thiazolo[4,5-c]carbazoles, naphtho[2,1-d]thiazoles and benzothiazole derivatives using Kumujian C as a template. This domino strategy proceeds through assembly of 1-formyl-9H-beta-carbolines, arylamines and elemental sulfur via formation of one C?N and two C?S bonds in a single operation. Importantly, the methodology was found applicable to beta-carboline acetals also. A diversely substituted library of 37 beta-carboline tethered arylthiazole hybrids was prepared in excellent yields. The strategy was found appropriate for gram scale synthesis also. The photophysical properties of these fluorophores were also estimated and showed excellent fluorescence properties with quantum yield (PhiF) up to 92 %.
