The present invention features benzoxazines, benzothiazines, and related compounds that inhibit nitric oxide synthase (NOS), particularly those that selectively inhibit neuronal nitric oxide synthase (nNOS) in preference to other NOS isoforms. The NOS inhibitors of the invention, alone or in combination with other pharmaceutically active agents, can be used for treating or preventing various medical conditions.
Starting from commercially available (hetero)aromatic nitriles and (1R,2R)-cyclohexane-1,2-diamine, nine NH-imidazolines (hexahydro-1H-benzo[d]imidazoles) were synthesized in good yields. The molecular structures of three imidazolines were confirmed by X-ray analysis. N-Benzylation afforded some of the desired N-benzylimidazolines, but was incompatible with imidazolines that possessed strong electron-accepting
从市售的(杂)芳族腈和(1 R,2 R)-环己烷-1,2-二胺开始,以高收率合成了九种NH-咪唑啉(六氢-1 H-苯并[ d ]咪唑)。通过X射线分析证实了三种咪唑啉的分子结构。N-苄基化提供了一些所需的N-苄基咪唑啉,但与在C2具有强电子接受杂芳族基团的咪唑啉不相容。在后一种情况下,产物在柱色谱法中分解形成N,N'-二取代的环己烷-1,2-二胺。 杂环-咪唑啉-手性池- N的-苄基-稳定性
Synthesis and Histamine H1 Receptor Agonist Activity of a Series of 2-Phenylhistamines, 2-Heteroarylhistamines, and Analogs
2-phenylhistamines (halogen = Br (35) and I (36)) were equipotent with histamine, while 2-(3-(trifluoromethyl)phenyl)histamine (2-[2-(3-(trifluoromethyl)phenyl)-1H-imidazol-4-yl]ethanamine (39)) was significantly more potent than histamine (39: pD2 = 6.81, relative activity = 128%). The 2-substituted histamine analogues were partial H1 receptor agonists on the endothelium-denuded isolated guinea pig aorta with

solvents, and reaction conditions revealed almost exclusive C5-lithiation. This regioselectivity is in contrast to the C3-lithiation reported for the oxazolino functionality (a cyclic imidate). The syntheticutility of the C5-lithiated intermediate of methyl N-methyl-thiophene-2-carboximidate with various electrophiles is demonstrated. C3-Lithiation has been effected in the case of methyl N-methylthi
