6 Hz active anticonvulsant fluorinated n-benzamide enaminones and their inhibitory neuronal activity
Amaye, Isis J.,Heinbockel, Thomas,Woods, Julia,Wang, Zejun,Martin-Caraballo, Miguel,Jackson-Ayotunde, Patrice
, (2018)
A small library of novel fluorinated N-benzamide enaminones were synthesized and evaluated in a battery of acute preclinical seizure models. Three compounds (GSA 62, TTA 35, and WWB 67) were found to have good anticonvulsant activity in the 6-Hz ‘psychomotor’ 44-mA rodent model. The focus of this study was to elucidate the active analogs’ mode of action on seizure-related molecular targets. Electrophysiology studies were employed to evaluate the compounds’ ability to inhibit neuronal activity in central olfactory neurons, mitral cells, and sensory-like ND7/23 cells, which express an assortment of voltage and ligand-gated ion channels. We did not find any significant effects of the three compounds on action potential generation in mitral cells. The treatment of ND7/23 cells with 50 μM of GSA 62, TTA 35, and WWB 67 generated a significant reduction in the amplitude of whole-cell sodium currents. Similar treatment of ND7/23 cells with these compounds had no effect on T-type calcium currents, indicating that fluorinated N-benzamide enaminone analogs may have a selective effect on voltage-gated sodium channels, but not calcium channels.

A highly efficient protocol for copper-catalyzed thio-alkynylation of enaminone-based thiocyanates with terminal alkynes under mild conditions has been developed. This scalable amino group-directed thio-alkynylation proceeds in the open air with a broad substrate scope and an excellent yield. The demonstrated synthetic transformation creates the opportunity for a wide variety of sulfur-containing useful materials. Gram-scale synthesis and further synthetic transformations of alkynyl sulfides highlight the potential utility of the method.

Aurora kinases as regulators of cell division have become promising therapeutic targets recently. Here we report novel, low molecular weight benzothiophene-3-carboxamide derivatives designed and optimized for inhibiting Aurora kinases. The most effective compound 36 inhibits Aurora kinases in vitro in the nanomolar range and diminishes HCT 116 cell viability blocking cytokinesis and inducing apoptosis. According to western blot analysis, the lead molecule inhibits Aurora kinases equipotently to VX-680 (Tozasertib) and similarly synergizes with other targeted drugs.

Cyclization of cyanoethylated ketones as a route to 6-substituted indole derivatives
Bergman, Jan,Stensland, Birgitta
, p. 1 - 10 (2014/02/14)
δ-Cyanoketones are quickly cyclized with KOtBu to 3-aminocyclohex-2-enone derivatives, which in turn will give substituted indoles when treated with oxalyl chloride. Thus, 3-amino-6,6-dimethylcyclohex-2-enone gave 3-chloro-6,6-dimethyl-2,5,6,7-tetrahydroindole-2,5-dione, whose structure was corroborated by X-ray crystallography, whereas the corresponding molecule without the blocking gem-dimethyl groups, 3-aminocyclohex-2-enone, gave via hydrogen shifts 6-chloro-3-hydroxyoxindole.

The facile procedure for the synthesis of the 11H-pyrido[3,2-a]carbazole structure involving the Fischer indole cyclization on tetrahydroquinolinones, available from enaminones and methyl 2-formyl-3-oxopropanoate, followed by the aromatization of the resulting 5,6-dihydro derivatives is described. This method allows for the introduction of substituents at C2, C6, and C8 to the scaffold by choice of the starting materials. In the biological testing, introduction of the phenyl group at C6 is significantly effective to improve the antiproliferative activity.

Jackson, Patrice L.,Hanson, Clive D.,Farrell, Alanna K.,Butcher, Raymond J.,Stables, James P.,Eddington, Natalie D.,Scott
experimental part, p. 42 - 51 (2012/07/28)
The x-ray crystal structure of 3-((5-methylisoxazol-3-yl)amino)-5- methylcyclohex-2-enone (12b) and 3-((5-methylisoxazolyl-3-yl)amino)-5,5- dimethylcyclohex-2-enone (12c) were determined and correlated to their anticonvulsant activity in mice and rats. A hypothesis for the toxicity of the analogs are advanced. In addition, a series of 5-methyl-N-(3-oxocyclohex-1-enyl) -isoxazole-3-carboxamides were synthesized and evaluated for anticonvulsant activity. These compounds were compared to the activity of the corresponding amino and aminomethyl enaminones. Additional investigation involved the synthesis and evaluation of a trifluoromethyl analog of the active isoxazole tert-butyl 4-(5-methisoxazol-3-yl-amino)-6-methyl-2-oxo-cyclohex-3-ene carboxylate (4f).

A comparison of enaminones from various unsubstituted and p-substituted benzamides to the analogous benzylamines has been undertaken with the aim of elucidating the essential structural parameters necessary for anticonvulsant activity. Initial studies on methyl 4-N-(benzylamino)-6-methyl-2-oxocyclohex- 3-en-1-oate, 3a, 3-N-(benzylamino)cyclohex-2-en-1-one, 3p, and 5,5-dimethyl- 3-N-(benzylamino)-cyclohex-2-en-1-one, 3r indicated that benzylamines possessed significant anti-maximal electroshock seizure (MES) activity. Evaluation of the analogous benzamides revealed significant differences in anticonvulsant activity, these differences were most probably related to the differences in their three-dimensional structures.
