Synthesis, antihypertensive and alpha-adrenoceptor activity of novel 2-aminoalkyl-3(2H)-pyridazinones

A number of 2-phenoxyalkylaminoalkyl- and 2-[1,4]benzodioxanylmethylaminoalkyl-3(2H)-pyridazinones were synthesized and tested for hypotensive and antihypertensive activity as well as for alpha1- and alpha2-adrenoceptor binding affinities. Some derivatives, eg 5.5, 5.9, 5.12, 6.4 and 6.10, showed strong hypotensive/antihypertensive effect and high affinity for alpha2- and alpha1-adrenoceptors. Compound 5.5 was selected for clinical study. In its mode of action a potassium channel opening activity may also be involved.

Electrophysiological and alarm behavioral responses of Solenopsis invicta Buren (Hymenoptera: Formicidae) to alkoxypyrazines

The red imported fire ant, Solenopsis invicta produces an alarm pheromone component, 2-ethyl-3,6-dimethylpyrazine, and responds to its pyrazine analogs in a similar manner but at varied detection thresholds. Herein, the responses of fire ant workers by electroantennogram (EAG) and behavior were tested with twelve structurally-related oxygen-containing pyrazines (alkoxypyrazines) and the synthetic alarm pheromone. All tested compounds elicited a dose-dependent EAG response, with S. invicta responding greatest to the synthetic alarm pheromone. Chemical structure of pyrazines influenced the EAG response but not always alarm behavioral response. Among the 13 tested compounds, 7 compounds displayed significantly greater EAG response than 2-isopropyl-3-methoxypyrazine and 2-ethoxy-3-isopropylpyrazine at the dose of 1000?mug. Four of these 7 compounds, 2-ethyl-3,6-dimethylpyrazine, 2-methoxy-3-methylpyrazine, 2-ethoxy-3(5 or 6)-methylpyrazine, and 2-chloro-3-methoxypyrazine with characteristic substituents on pyrazine ring were further subjected to bait discovery bioassay. Hotdog bait containing pyrazines attracted significantly more fire ant workers in the first 15-min period, resulting in quicker recruitment to food block than hexane control. The potential of using alkoxypyrazines in fire ant control is discussed.

Synthesis and pharmacological properties of ureidomethylcarbamoylphenylketone derivatives. A new potent and subtype-selective nonpeptide CCK-B/gastrin receptor antagonist, S-0509

A novel series of CCK-B/gastrin receptor antagonists – ureidomethylcarbamoylphenylketone derivatives – were designed, synthesized, and evaluated for activity. Structure-activity relationship studies revealed the importance of a carboxylic acid at substituent R2 and a tert-butoxycarbonyl group at R1 in structure A. Compound 7a (S-0509) showed remarkable affinity for the CCK-B/gastrin receptor and a subtype selectivity profile in vitro. Administration (id) of 7a led to excellent inhibition of gastric acid secretion induced by pentagastrin in anesthetized rats with an ED50 value of 0.014 mg/kg. Furthermore, 7a proved to have poor blood-brain permeability by its small effect on enhancement of morphine analgesia. Thus, S-0509 has an increase in selectivity for the peripheral effects of gastrin antagonism from the central effects of CCK-B antagonism.

Synthesis, herbicidal activities, and 3D-QSAR of 2-cyanoacrylates containing aromatic methylamine moieties

A series of novel 2-cyanoacrylates containing different aromatic rings were synthesized, and their structures were characterized by 1H NMR, elemental analysis, and single-crystal X-ray diffraction analysis. Their herbicidal activities against four weeds and inhibition of photosynthetic electron transport against isolated chloroplasts (the Hill reaction) were evaluated. Both in vivo and in vitro data showed that the compounds containing benzene, pyridine, and thiazole moieties gave higher activities than those containing pyrimidine, pyridazine, furan, and tetrahedronfuran moieties. To further explore the comprehensive structure-activity relationship on the basis of in vitro data, comparative molecular field analysis (CoMFA) was performed, and the results showed that a bulky and electronegative group around the para-position of the aromatic rings would have the potential for higher activity, which offered important structural insights into designing highly active compounds prior to the next synthesis.

Deprotonative metalation of substituted benzenes and heteroaromatics using amino/alkyl mixed lithium-zinc combinations

Different homoleptic and heteroleptic lithium-zinc combinations were prepared, and structural elements obtained on the basis of NMR spectroscopic experiments and DFT calculations. In light of their ability to metalate anisole, pathways were proposed to justify the synergy observed for some mixtures. The best basic mixtures were obtained either by combining ZnCl 2¡¤TMEDA (TMEDA = N,N,N’,N’tetramethylethylenediamine) with [Li(tmp)] (tmp = 2,2,6,6-tetramethylpiperidino; 3 equiv) or by replacing one of the tmp in the precedent mixture with an alkyl group. The reactivity of the aromatic lithium zincates supposedly formed was next studied, and proved to be substrate-, base-, and electrophile-dependent. The aromatic lithium zincates were finally involved in palladium-catalyzed cross-coupling reactions with aromatic chlorides and bromides.

Medium-Ring Nitrogen Heterocycles through Migratory Ring Expansion of Metalated Ureas

Simple benzo-fused nitrogen heterocycles (indolines, tetrahydroquinolines, and their homologues) undergo migratory ring expansion through deprotonation of their benzylic urea derivatives with lithium diisopropylamide (LDA) in the presence of N,N?-dimethylpropylideneurea (DMPU). The products of the reactions are benzodiazepines, benzodiazocines, and their homologues, with ring sizes of 8?12. The reactions tolerate a range of substituent patterns and types, and may exhibit enantiospecificity or diastereoselectivity. Considerable complexity is rapidly generated in an efficient synthesis of these otherwise difficult-to-obtain medium-ring nitrogen heterocycles.
