Development of potent serotonin-3 (5-HT3) receptor antagonists. II. Structure-activity relationships of N-(1-benzyl-4-methylhexahydro-1H-1,4- diazepin-6-yl)carboxamides

Our studies on 4-amino-5-chloro-2-ethoxybenzamides led to the discovery that the N-(1,4-dimethylhexahydro-1H-1,4-diazepin-6-yl)benzamide 9 and the 1- benzyl-4-methylhexahydro-1H-1,4-diazepine analogue 10 are potent serotonin-3 (5-HT3) receptor antagonists. Structure-activity relationship (SAR) studies on the influence of the aromatic nucleus of 9 and 10 upon inhibition of the von Bezold-Jarisch reflex in rats are described. Heteroaromatic rings such as pyrrole, thiophene, furan, pyridine, pyridaziae, 1,2-benzisoxazole, indole, quinoline, and isoquinoline rings showed weak 5-HT3 receptor antagonistic activity. Within this series, use of the 1H-indazole ring as an aromatic moiety led to a substantial increase of the activity; the 1H- indazolylcarboxamides 54, 57, 97, and 102 showed potent 5-HT3 receptor antagonistic activity. The optimal compound identified via extensive SAR studies was N-(1-benzyl-4-methylhexahydro-1H-1,4-diazepin-6-yl)-1H-indazole- 3-carboxamide (54), whose effect was superior to that of the corresponding benzamide 10 and essentially equipotent to those of ondansetron (1) and granisetron (4).

Catalyst-Free Synthesis of 2-Anilinoquinolines and 3-Hydroxyquinolines via Three-Component Reaction of Quinoline N-Oxides, Aryldiazonium Salts, and Acetonitrile

A rapid microwave-assisted, catalyst-free, three-component synthesis of various 2-anilinoquinolines from quinoline N-oxides and aryldiazonium salts in acetonitrile under microwave irradiation is reported. This reaction utilizes acetonitrile as a single nitrogen source and involves the formation of two new C-N bonds via the formal [3 + 2] cycloaddition reaction. In the case of 2-substituted quinolines, 3-hydroxyquinoline was observed as the main product via a 1,3 shift of the oxygen atom from N-oxide to the C3 position of quinolines.

Benzotriazole-containing donor-acceptor-acceptor type cyclometalated iridium(III) complex for solution-processed near-infrared polymer light emitting diodes

A novel near-infrared-emitting cyclometalated iridium(III) complex of (CH3OTPA-BTz-Iq)2Irpic containing benzotriazole unit with a donor-acceptor-acceptor (D-A-A) chromophore was synthesized and characterized. The optophysical, electrochemical and electroluminescent characteristics were primarily studied. A near-infrared emission peaked at 716 nm with a shoulder at 790 nm was exhibited in the (CH3OTPA-BTz-Iq)2Irpic dichloromethane solution at 298 K. In its optimized solution-processed polymer light-emitting diodes, a near-infrared electroluminescent emission peaked at 723 nm with a shoulder at 780 nm was observed with a maximum external quantum efficiency of 0.41% at 8.14 mA cm-2. This work indicates that introducing appropriate D and A units to develop D-A-A structure is an efficient approach to construct near-infrared-emitting iridium(III) complex in the polymer light-emitting diodes with suppressive efficiency roll-off.

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.SDS of cas: 1532-71-4, you can also check out more blogs about1532-71-4

A Garratt-Braverman cyclization route towards the synthesis of phenanthridine derivatives and their DNA-binding studies

Garratt-Braverman cyclization has been employed to synthesize a series of dihydroisofuran fused phenanthridine derivatives. The established protocol proposes a simpler synthetic alternative to have access to these therapeutically relevant cytotoxic scaffolds. Single crystal X-ray data unambiguously confirmed the structures of the synthesized phenanthridine derivatives. UV?Vis absorption titration with calf-thymus DNA followed by fluorescence-based competitive ethidium bromide displacement assay established the synthesized target compounds as potent DNA-intercalating agents with intrinsic binding constant of the range 103-105. Results obtained from the molecular docking further justified the spectroscopically obtained results.

Conformations, structure, vibrations, chemical shift and reactivity properties of isoquinoline?1?carboxylic acid and isoquinoline?3?carboxylic acid ? Comparative investigations by experimental and theoretical techniques

The most stable conformer of isoquinoline?1?carboxylic acid (IQ1CA) and isoquinoline?3?carboxylic acid (IQ3CA) are determined and the geometry has been optimised with B3LYP method using high level 6?311++G** and cc?pVTZ basis sets. The structure, electronic properties, vibrational fundamental modes, thermodynamic properties and chemical shifts of the compounds are investigated. The vibrational fundamental modes are assigned and analysed by utilising FT?IR and FT?Raman spectrum of the compounds recorded in the range of 4000?400 and 4000?100 cm?1, respectively. The LUMO?HOMO energy difference is determined to explain the charge transfer within the molecule. The molecular electrostatic potential and total electron density of the molecules are determined to explain the size, shape and the reactive sites (polar) of the molecules. The 1H and 13C NMR chemical shifts of the compounds are determined by Gauge Invariant Atomic Orbital (GIAO) method using DMSO?d6 solvent by B3LYP/cc?pVTZ method. The local and global chemical reactivity properties of the compounds have been investigated with the help of global and local reactivity descriptors.

Diastereomers of a cofacial ternaphthalene and two azaternaphthalenes. Syntheses and barriers to isomerization

The title compounds, a mixture of anti and syn diastereomers, were prepared by Pd-catalyzed coupling of areneboronic acids with hetaryl halides.

Exploring the influence of the protein environment on metal-binding pharmacophores

The binding of a series of metal-binding pharmacophores (MBPs) related to the ligand 1-hydroxypyridine-2-(1H)-thione (1,2-HOPTO) in the active site of human carbonic anhydrase II (hCAII) has been investigated. The presence and/or position of a single methyl substituent drastically alters inhibitor potency and can result in coordination modes not observed in small-molecule model complexes. It is shown that this unexpected binding mode is the result of a steric clash between the methyl group and a highly ordered water network in the active site that is further stabilized by the formation of a hydrogen bond and favorable hydrophobic contacts. The affinity of MBPs is dependent on a large number of factors including donor atom identity, orientation, electrostatics, and van der Waals interactions. These results suggest that metal coordination by metalloenzyme inhibitors is a malleable interaction and that it is thus more appropriate to consider the metal-binding motif of these inhibitors as a pharmacophore rather than a “chelator”. The rational design of inhibitors targeting metalloenzymes will benefit greatly from a deeper understanding of the interplay between the variety of forces governing the binding of MBPs to active site metal ions.
