Synthesis, anti-convulsant activity and molecular docking study of novel thiazole pyridazinone hybrid analogues

Pyridazinone analogues have been known to be potential candidates for anticonvulsant agents. We have identified several pyridazinone-based anticonvulsant agents. As a continuation to our previous research, a series of hybrid pyridazinone-thiazole connected through amide linkage were designed and synthesized. Among these, compound SP-5F demonstrated significant anticonvulsant activity with median effective dose of 24.38 mg/kg (MES) and 88.23 mg/kg (scPTz). Results of GABA estimation showed a marked increase in the GABA level when compared with control. Molecular docking studies at the active site of GABA receptor, further confirmed the GABA modulatory effects of SP-5F.

Divergent Access to (1,1) and (1,2)-Azidolactones from Alkenes using Hypervalent Iodine Reagents

A versatile synthesis of azidolactones through azidation and cyclization of carboxylic acids onto alkenes has been developed. Based on either photoredox or palladium catalysis, (1,1) and (1,2) azido lactones can be selectively synthesized. The choice of catalyst and benziodoxol(on)e reagent serving as azide source was essential to initiate either a radical or Lewis acid mediated process with divergent outcome. These transformations were carried out under mild conditions using a low catalyst loading and gave access to a large scope of azido lactones.

Design, Synthesis, and Pharmacological Screening of Pyridazinone Hybrids as Anticonvulsant Agents

A series of new hybrid benzimidazole containing pyridazinones derivatives were designed and synthesized in accordance with the pharmacophoric requirements essential for the anticonvulsant activity. The synthesized compounds were evaluated for anticonvulsant activity on mice by the gold standard maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ)-induced seizure models. Among the compounds tested, SS-4F showed significant anticonvulsant activity in both the screens with ED50 values of 25.10 and 85.33 mg/kg in the MES and scPTZ screens, respectively. Compound SS-4F emerged as safer and effective anticonvulsant due to its several-fold higher protective indices. Further, the gamma-aminobutyric acid (GABA) estimation result showed a marked increase in the GABA level (1.7-fold) as compared to the control, which was further confirmed by good binding properties with the GABAA receptor.

One-pot synthesis of tetralin derivatives from 3-benzoylpropionic acids: Indium-catalyzed hydrosilylation of ketones and carboxylic acids and intramolecular cyclization

This reducing system was composed of a small amount (1 mol%) of In(OAc)3, Me2PhSiH, and I2 that effectively catalyzed the hydrosilylation of two different carbonyl groups, a ketone and a carboxylic acid found in 3-benzoylpropionic acids, followed by a subsequent intramolecular cyclization that led to the one-pot preparation of tetralin derivatives.

Iron-catalyzed arene alkylation reactions with unactivated secondary alcohols

A simple, iron-based catalytic system allows for the inter- and intramolecular arylation of unactivated secondary alcohols. This transformation expands the substrate scope beyond the previously required activated alcohols and proceeds under mild reaction conditions, tolerating air and moisture. Furthermore, the use of an enantioenriched secondary alcohol provides an enantioenriched product for the intramolecular reaction, thereby offering a convenient approach to nonracemic products.

An alternative route to syntheses of aryl keto acids in a chloroaluminate ionic liquid

The Lewis acidic 1-butyl-3-methylimidazolium chloroaluminate ionic liquid [bmim]Cl.AlCl3, N=0.67, is employed as a catalyst as well as the solvent for the quick and efficient syntheses of aryl keto acids by Friedel-Crafts acylation and aroylation of aromatic hydrocarbons using cyclic acid anhydrides.

Direct synthesis of γ-butyrolactones via γ-phenyl substituted butyric acids mediated benzyl radical cyclization

Synthesis of several γ-butyrolactones with aromatic substitution at carbon 5 from comparative γ-aryl acids with 25-85% yield are covered. The straight oxidation in the presence of peroxydisulphate-copper(II)chloride system in aqueous medium was applied. The reaction is highly regioselective and leads exclusively to γ-butyrolactone, through stable benzylic radical intermediate.

Syntheses and antiinflammatory activity of some 6-aryl-2,3,4,5-tetrahydro-3-pyridazinones

6-Aryl-2, 3, 4, 5-tetrahydro-3-pyridazinones (2c-22c) are obtained by dehydrocyclisation of various hydrazides formed by the reaction of appropriate methyl β-aroylpropionate and hydrazine hydrate in the presence of anhydrous sodium acetate. They show promising antiinflammatory activity during their evaluation by carrageenin induced paw edema test in rats.

Modern Friedel-Crafts chemistry XIII. Intra- and intermolecular cyclization of some carbonyl derivatives under Friedel-Crafts conditions

Carbonyl group deactivation in the cycloalkylation of aryl haloalkyl ketones was studied.Ketones 1-5 were prepared and subjected to treatment with AlCl3, AlCl3/H2SO4 and H2SO4 catalysts.Whereas AlCl3 catalyst gave no cyclization products, the use of AlCl3/H2SO4 and H2SO4 catalysts afforded the corresponding indanones and/or tetralones (6-11).The intermediate p-methylacrylophenone (12) was also obtained in the case of ketone 2.Furthermore intermolecular cyclizations of benzene, toluene and p-xylene with 3-chloropropionyl chloride (13) and 4-chlorobutyryl chloride (14) were investigated.In the presence of AlCl3/CH3NO2 catalyst, only the corresponding aryl haloalkyl ketones (1-5) were formed whereas the use of AlCl3 catalyst gave, in addition, some cyclic ketones.However, the use of AlCl3/H2SO4 catalyst gave only the corresponding cyclic ketones (6-11).Results are discussed and mechanisms are suggested.In conclusion, carbonyl group deactivation for ring closure is demonstrated in the investigated ketones and cyclization can only effected under strenuous conditions.
