Selective and irreversible inhibitors of neuronal isoform of nitric oxide synthase catalyzed production of nitric oxide are L-ornithine or L-lysine derivatives having the formula ##STR1## wherein Q is H or (CH.sub.2).sub.r CH.sub.3 where r ranges from 0 to 15, x is 1 or 2, R" is CH.sub.2 or C(H) (CH.sub.2).sub.y CH.sub.3 where y ranges from 0 to 5, R' is CH.sub.2 or C(H) (CH.sub.2).sub.z CH.sub.3 where z ranges from 0 to 5, R is H or (CH.sub.2).sub.s CH.sub.3 where s ranges from 0 to 5, with none or only one of R, R' and R" providing an alkyl substituent on ornithine or lysine moiety, R.sup.III is OH or is an alkoxy group of 1 to 6 carbon atoms or is an amino acid or peptide attached in amide linkage through its free .alpha.-amino group, and R.sup.IV is --H or an acyl group of 1 to 6 carbon atoms or is an amino acid or peptide attached in amide linkage through its free .alpha.-carboxylate group, and mixtures thereof with corresponding D-isomers. A preferred compound is N.sup.5 -(1-imino-3-butenyl)-L-ornithine. The compounds are useful for treatment of migraine headaches, stroke, pain due to stimulation of nNOS-containing neurons including chronic visceral pain, drug addiction, Parkinson's disease, schizophrenia, and epilepsy.
具有以下结构的L-鸟氨酸或L-赖氨酸衍生物是神经型一氧化氮合酶的选择性和不可逆抑制剂,催化一氧化氮的生成:其中Q为H或(CH₂)ᵣCH₃,其中r范围为0至15,x为1或2,R"为CH₂或C(H)(CH₂)ᵧCH₃,其中y范围为0至5,R'为CH₂或C(H)(CH₂)ᶻCH₃,其中z范围为0至5,R为H或(CH₂)ₛCH₃,其中s范围为0至5,其中R、R'和R"中的一个或仅一个在鸟氨酸或赖氨酸基团上提供烷基取代基,R.sup.III为OH或为1至6个碳原子的烷氧基团或通过其自由α-氨基团连接的氨基酸或肽的酰胺键连接,R.sup.IV为-H或为1至6个碳原子的酰基团或通过其自由α-羧基团连接的氨基酸或肽的酰胺键连接,以及与相应的D-异构体的混合物。一种首选化合物是N⁵-(1-亚硝基-3-丁烯基)-L-鸟氨酸。这些化合物可用于治疗偏头痛、中风、由刺激含nNOS的神经元引起的疼痛,包括慢性内脏疼痛、药物成瘾、帕金森病、精神分裂症和癫痫。
