Synthesis and biological evaluation of novel N-substituted (3-(1-aminoethylidene)-2-oxochroman-4-yl)phosphonic acid diethyl ester derivatives as anti-Alzheimer agent

Abstract: A novel scaffold of N-substituted (3-(1-aminoethylidene)-2-oxochroman-4-yl)phosphonic acid diethyl ester derivatives was designed, synthesized and evaluated as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors against Alzheimer?s disease. Compounds 2a, 2b, 2d and 2q proved to be more potent than the standard drug galantamine and rivastigmine for AChE inhibitory activity with IC50 value between 0.50 and 3.94?muM. All the synthesized compounds proved to be only weak BuChE inhibitors. The compounds showed cytotoxicity in the same range as that of standard drugs against HEK-293 cells. Molecular docking studies suggested that compound 2q is acting as a dual binding site inhibitor by occupying the enzymatic catalytic active site, mid-gorge and peripheral anionic site. The coumarin moiety showed a pi?pi stacking interaction with Trp84 and hydrogen bonds with the P=O and C=O was found with Ser122 and Tyr121 at the catalytic active site. At the peripheral anionic site, the phenyl ring and quinoline ring were stacked against the Tyr 334 and Trp279 through pi?pi stacking interaction, respectively. The predicted ADME showed a good pharmacokinetic profile. DNA cleavage studies suggested that compounds 2a, 2b, 2d and 2q can be considered as non-toxic. Thus, compound 2q could be a promising lead structure for further development as anti-Alzheimer agents. Graphic abstract: [Figure not available: see fulltext.].

Synthesis and antibacterial activity of cinnamaldehyde acylhydrazone with a 1,4-benzodioxan fragment as a novel class of potent ss-Ketoacyl-acyl carrier protein synthase III (FabH) inhibitor

Fatty acid biosynthesis is essential for bacterial survival. ss-Ketoacyl-acyl carrier protein (ACP) synthase III (FabH), is a particularly attractive antibacterial target, since it is central to the initiation of fatty acid biosynthesis. Three series of 21 cinnamaldehyde acylhydrazone derivatives, A3-9, B3-9, and C3-9, were synthesized and evaluated for FabH-inhibitory activity. Compound B6 showed the most potent biological activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus subtilis (minimum inhibitory concentrations (MICs) values: 1.56-3.13mug/mL) and was comparable with the positive control. Docking simulation by positioning compound B6 in the FabH structure active site was performed to explore the possible binding model.

Achieving High Ortho Selectivity in Aniline C-H Borylations by Modifying Boron Substituents

High ortho selectivity for Ir-catalyzed C-H borylations (CHBs) of anilines results when B2eg2 (eg = ethylene glycolate) is used as the borylating reagent in lieu of B2pin2, which is known to give isomeric mixtures with anilines lacking a blocking group at the 4-position. With this modification, high selectivities and good yields are now possible for various anilines, including those with groups at the 2- and 3-positions. Experiments indicate that ArylN(H)Beg species are generated prior to CHB and support the improved ortho selectivity relative to B2pin2 reactions arising from smaller Beg ligands on the Ir catalyst. The lowest-energy transition states (TSs) from density functional theory computational analyses have N-H¡¤¡¤¡¤O hydrogen-bonding interactions between PhN(H)Beg and O atoms in Beg ligands. Ir-catalyzed CHB of PhN(H)Me with B2eg2 is also highly ortho-selective. 1H NMR experiments show that N-borylation fully generates PhN(Me)Beg prior to CHB. The TS with the lowest Gibbs energy was the ortho TS, in which the Beg unit is oriented anti to the bipyridine ligand.

Synthesis of fused pyrroles containing 4-hydroxycoumarins by regioselective metal-free multicomponent reactions

The reaction of arylglyoxals, 4-hydroxycoumarin, and aromatic amines such as 7-amino-2-methylchromone, 6/7-aminoflavone, 7-amino-4-methylcoumarin, 1-amino-9-fluorenone, 1-aminoanthraquinone and aniline derivatives in acetic acid medium under microwave conditions provides the corresponding regioselective fused pyrroles having hydroxycoumarin and aryl substituents. Alternatively, we have developed another method using in situ arylglyoxals from acetophenone derivatives by I2/DMSO promoted C-H oxidation followed by one-pot three component cyclization reactions to provide similar fused pyrroles. Using both the methods a series of novel pyrroles fused with pharmacologically important chromone, flavone, coumarin, fluorenone, and anthraquinone moieties were synthesized under metal-free reaction conditions in good to very good yields within a short reaction time. The structures of the synthesized fused pyrroles have been unambiguously confirmed by spectroscopic techniques, mass analysis and single crystal XRD.
