Design, synthesis, crystal structure, and herbicidal activity of novel pyrrolidine-2,4-dione derivatives incorporating an alkyl ether pharmacophore with natural tetramic acids as lead compounds

In order to discover green herbicides with novel molecular scaffolds, natural tetramic acids were used as lead compounds to design and synthesize four pyrrolidine-2,4-dione derivatives incorporating a chainlike alkoxyalkyl moiety (4a-4d) and nineteen pyrrolidine-2,4-dione derivatives incorporating a substituted phenoxyethyl moiety (10a-10s)viasubstitution, acylation, cyclization, and acidification reactions. The synthesized target compounds were confirmed by FT-IR,1H NMR,13C NMR and HRMS spectral analyses. The single-crystal structure of compound10awas analyzed by X-ray diffraction, which revealed that the 1-hydroxyethylidene group links the third position of the pyrrolidine heterocycle through a double bond with theZ-configuration. The herbicidal activity was evaluated using barnyard grass (Echinochloa crus-galli) and rape (Brassica campestris) as model plants by a Petri dish culture method. Most target compounds were found to possess moderate to good inhibitory activities against the plant growth at 100 μg mL?1. Among them, the compounds10qand10nshowed the highest herbicidal activities against the roots of barnyard grass and rape seedlings with the corresponding inhibition rates of 65.6% and 84.0%, respectively. This result indicated that pyrrolidine-2,4-dione derivatives incorporating a substituted phenoxyethyl moiety are worthy of further structural optimization.

Identification of N-(2-Phenoxyethyl)imidazo[1,2-a]pyridine-3-carboxamides as New Antituberculosis Agents

A series of imidazo[1,2-a]pyridine carboxamides (IPAs) bearing an N-(2-phenoxyethyl) moiety was designed and synthesized as new antitubercular agents. Seven 2,6-dimethyl IPAs demonstrated excellent in vitro activity (MIC: 0.025-0.054 μg/mL) against the drug susceptive H37Rv strain and two clinically isolated multidrug-resistant Mycobacterium tuberculosisstrains. Compound 10j displayed acceptable safety and pharmacokinetic properties, opening a new direction for further development.

Synthesis and antitumor activity of 5-(5-halogenated-2-oxo-1H-pyrrolo[2,3-b]pyridin-(3Z)-ylidenemethyl)-2,4-dimethyl-1H-pyrrole-3-carboxamides

We report herein the design and synthesis of a series of novel 5-halogenated-7-azaindolin-2-one derivatives containing a 2,4-dimethylpyrrole moiety. Nine target compounds with ≥70% inhibition against MCF-7 at 30 μM were further evaluated for their in vitro antitumor activity against seven human cancer cell lines by SRB assay. Results reveal that some compounds have potent antitumor activity, and the most active 13c7 (IC50s: 4.49-15.39 μM) was found to be more active than Sunitinib (IC50s: 4.70->30 μM) against all of the tested cancer cell lines.

Synthesis, biological evaluation of 9-N-substituted berberine derivatives as multi-functional agents of antioxidant, inhibitors of acetylcholinesterase, butyrylcholinesterase and amyloid-β aggregation

A series of 9-N-substituted berberine derivatives were synthesized and biologically evaluated as antioxidant and inhibitors of acetylcholinesterase (AChE), butyrylcholinesterase and amyloid-β aggregation. Most of these compounds exhibited very good antioxidant activities, inhibitive activities of AChE and amyloid-β aggregation. Among them, compound 8d, (o-methylphenethyl)amino linked at the 9-position of berberine, was found to be a good antioxidant (with 4.05 μM of Trolox equivalents), potent inhibitor of AChE (an IC50 value of 0.027 μM), and high active inhibitor of amyloid-β aggregation (an IC50 value of 2.73 μM).

A Synthesis of acetamidines

The condensation of primary amine with N,N-dimethylacetamide dimethyl acetal yields amixture of acetamidine and imidate ester. The product distribution in this reaction depends on the temperature, solvent, and structure of the primary amine. It is possible to suppress the formation of imidate ester by performing the reaction in the presence of excess dimethyl amine, yielding acetamidine as the exclusive product. For acetamidines that cannot be purified either by crystallization or distillation, this new method is necessary for the generation of pure acetamidines in good yields.

Anti-infective compounds

The present invention relates to small molecule compounds and their use in the treatment of bacterial infections, in particular Tuberculosis.

New N-(phenoxydecyl)phthalimide derivatives displaying potent inhibition activity towards α-glucosidase

Several members of a new family of non-sugar-type α-glucosidase inhibitors, bearing a phthalimide moiety connected to a variously substituted phenoxy ring by an alkyl chain, were synthesized and their activities were investigated. The efficacy of the inhibition activity appeared to be governed by the chain length of the substrate. Substrates possessing 10 carbons afforded the highest levels of activity, which were one to two orders of magnitude more potent than the known inhibitor 1-deoxynojirimycin (dNM). Furthermore, structure-activity relationship studies indicated a critical role of electron-withdrawing substituents at the phenoxy group for the activity. Derivatives bearing a chlorine atom along with a strong electron-withdrawing group, such as a nitro group, were the most potent of the series.

Design, synthesis, and pharmacological effects of structurally simple ligands for MT1 and MT2 melatonin receptors

A series of phenoxyalkyl and phenylthioalkyl amides were prepared as melatoninergic ligands. Modulation of affinity of the newly synthesized compound by applying SARs around the terminal amide moiety, the alkyl chain, and the methoxy group on the aromatic ring provides compounds with nanomolar affinity for both melatonin receptor subtypes. Affinity towards MT1 and MT2 receptors were modulated also exploiting chirality. The investigation of intrinsic activity revealed that all the tested compounds behave as full or partial agonists.
