Design, synthesis and anticonvulsant activity of new hybrid compounds derived from N-phenyl-2-(2,5-dioxopyrrolidin-1-yl)-propanamides and -butanamides

The focused library of 21 new N-phenyl-2-(2,5-dioxopyrrolidin-1-yl)propanamide, 2-(3-methyl-2,5-dioxopyrrolidin-1-yl)propanamide, and 2-(2,5-dioxopyrrolidin-1-yl)butanamide derivatives as potential new hybrid anticonvulsant agents was synthesized. These hybrid molecules were obtained as close analogs of previously described N-benzyl derivatives and fuse the chemical fragments of clinically relevant antiepileptic drugs such as ethosuximide, levetiracetam, and lacosamide. The initial anticonvulsant screening was performed in mice (ip) using the ‘classical’ maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) tests, as well as in the six-Hertz (6 Hz) model of pharmacoresistant limbic seizures. Applying the rotarod test, the acute neurological toxicity was determined. The broad spectra of activity across the preclinical seizure models in mice (ip) displayed compounds 4, 5, 11, and 19. The most favorable anticonvulsant properties demonstrated 4 (ED50 MES = 96.9 mg/kg, ED50 scPTZ = 75.4 mg/kg, ED50 6 Hz = 44.3 mg/kg) which showed TD50 = 335.8 mg/kg in the rotarod test that yielded satisfying protective indexes (PI MES = 3.5, PI scPTZ = 4.4, PI 6 Hz = 7.6). Consequently, compound 4 revealed comparable or better safety profile than model antiepileptic drugs (AEDs): ethosuximide, lacosamide, and valproic acid. In the in vitro assays, compound 4 was observed as relatively effective binder to the neuronal voltage-sensitive sodium and diltiazem site of L-type calcium channels.

Exploiting rhizosphere microbial cooperation for developing sustainable agriculture strategies

The rhizosphere hosts a considerable microbial community. Among that community, bacteria called plant growth-promoting rhizobacteria (PGPR) can promote plant growth and defense against diseases using diverse distinct plant-beneficial functions. Crop inoculation with PGPR could allow to reduce the use of pesticides and fertilizers in agrosystems. However, microbial crop protection and growth stimulation would be more efficient if cooperation between rhizosphere bacterial populations was taken into account when developing biocontrol agents and biostimulants. Rhizospheric bacteria live in multi-species biofilms formed all along the root surface or sometimes inside the plants (i.e., endophyte). PGPR cooperate with their host plants and also with other microbial populations inside biofilms. These interactions are mediated by a large diversity of microbial metabolites and physical signals that trigger cell?cell communication and appropriate responses. A better understanding of bacterial behavior and microbial cooperation in the rhizosphere could allow for a more successful use of bacteria in sustainable agriculture. This review presents an ecological view of microbial cooperation in agrosystems and lays the emphasis on the main microbial metabolites involved in microbial cooperation, plant health protection, and plant growth stimulation. Eco-friendly inoculant consortia that will foster microbe?microbe and microbe?plant cooperation can be developed to promote crop growth and restore biodiversity and functions lost in agrosystems.

Synthesis and pharmacological evaluation of 6-arylpyridazinones as potent vasorelaxants

Preclinical Research As part of a research program to identify compounds with potent antihypertensive properties, a new series of dihydropyridazin-3(2H)- one analogs was synthesized and evaluated for vasodilator activity in rat thoracic aortic rings. Most of the newly synthesized compounds displayed good vasorelaxant activity as compared with SK&F-93741 and hydralazine, with the N2-unsubstituted 4-isobutyramidophenylpyridazinone derivative 5 being the most potent vasorelaxant, producing vasorelaxation greater than that of hydralazine and equipotent to SK&F-93741. A significant effect of the 6-phenyl substituents and substitution at N-2 position of pyridazinone nucleus on the vasodilatory activity was observed.

Autoxidation of Nonane and Decane: A Product Study

The autoxidation of nonane and decane has been shown to occur in three stages.The initial stage leads to alkyl hydroperoxide formation and in the second stage the hydroperoxide decomposes to produce alcohols and ketones as major products.These studies support the proposal that hydroperoxide decomposition in the second stage occurs by a radical-induced decomposition.In the third stage the products are oxidised in competition with the alkane.Under the conditions of the autoxidation, the alkanes produce gamma-lactones as the major ester components and carboxylic acids are formed in the latter stages of the autoxidation.Decan-2-one is shown to be the precursor of heptan-1-ol and octanal

Synthesis of N-(3-phenylpropyl)-substituted tricyclic ABE ring analogues of the alkaloid methyllycaconitine

The synthesis of several ABE tricyclic analogues 5, 31 and 32 of the alkaloid methyllycaconitine (1) is reported. The analogues contain two key pharmacophores: a tertiary N-(3-phenylpropyl) substituent attached to a 3-azabicyclo-[3.3.1]nonane ring system and a 2-(3-methyl-2,5-dioxopyrrolidin-1- yl)benzoate ester. Double Mannich reaction of the cyclic beta-keto esters 6 and 17 with the bis(aminol) ether 7 using methyltrichlorosilane as an activating agent provided an efficient method for the construction of the 3-azabicyclo[3.3.1]nonanes 8 and 18. Ring-closing metathesis of the derived dienes 11, 19, and 20 afforded the tricyclic ethers 12, 21, and 22, respectively, the C-8 ester of which was reduced to a hydroxymethyl group to form the ABE tricyclic analogues 13, 23, and 24. Conversion of the alcohol 13 to the anthranilate ester 14 using N-(trifluoroacetyl)anthranilic acid followed by fusion with methylsuccinic anhydride afforded the analogue 5 containing the key N-(methylsuccinimido) anthranilate pharmacophore. In the case of the alcohols 23 and 24 the 2-(3-methyl-2,5-dioxopyrrolidin-1-yl)benzoate ester pharmacophore was appended by direct esterification with unsaturated acid 28 followed by hydrogenation to the ABE tricyclic compounds 33 and 34.

Mechanistic study of a one-step catalytic conversion of fructose to 2,5-dimethyltetrahydrofuran

Carbohydrates, such as fructose, can be fully dehydroxylated to 2,5-dimethyltetrahydrofuran (DMTHF), a valuable chemical and potential gasoline substitute, by the use of a dual catalytic system consisting of HI and RhX 3 (X=Cl, I). A mechanistic study has been carried out to understand the roles that both acid and metal play in the reaction. HI serves a two-fold purpose: HI acts as a dehydration agent (loss of 3 H2O) in the initial step of the reaction, and as a reducing agent for the conjugated carbinol group in a subsequent step. I2 is formed in the reduction step and metal-catalyzed hydrogenation reforms HI. The rhodium catalyst, in addition to catalyzing the reaction of iodine with hydrogen, functions as a hydrogenation catalyst for C=O and C=C bonds. A general mechanistic scheme for the overall reaction is proposed based on identification of intermediates, independent reactions of the intermediates, and deuterium labeling studies. Copyright

Pyridine carboxamides: Potent palm site inhibitors of HCV NS5B polymerase

Pyridine carboxamide-based inhibitors of the hepatitis C virus (HCV) NS5B polymerase were diversified and optimized to a variety of topologically related scaffolds. In particular, the 2-methyl nicotinic acid scaffold was developed into inhibitors with improved biochemical (IC50-GT1b = 0.014 muM) and cell-based HCV replicon potency (EC50-GT1b = 0.7 muM). Biophysical and biochemical characterization identified this novel series of compounds as palm site binders to HCV polymerase.
