    • Administration of argininosuccinate synthetase activity reducing agents, e.g., argininosuccinate synthetase induction blocking agents (e.g., antibiotics that bind to DNA sequences present in the upstream regulatory region of the argininosuccinate synthetase gene, such as mithramycin) and argininosuccinate synthetase inhibitors (e.g., L-citrulline antagonists such as methyl citrulline and L-aspartate antagonists such as D-aspartate) is useful to prevent or treat sepsis or cytokine-induced systemic hypotension, is useful in the treatment of sepsis or cytokine-induced systemic hypotension to restore vascular sensitivity to the effects of .alpha..sub.1 -adrenergic agonists, and is useful to suppress an immune response, e.g., in treating inflammation. In one embodiment, certain argininosuccinate synthetase activity reducing agents are used together with arginine antagonists to treat sepsis or cytokine induced hypotension.
    • 精氨基琥珀酸合成酶活性降低剂的施用,例如精氨基琥珀酸合成酶诱导阻断剂(例如,结合存在于精氨基琥珀酸合成酶基因的上游调节区域中的DNA序列的抗生素,例如霉素霉素)和精氨基琥珀酸合成酶抑制剂(例如L-瓜氨酸 拮抗剂如瓜氨酸甲酯和L-天冬氨酸拮抗剂如D-天冬氨酸)可用于预防或治疗败血症或细胞因子诱导的全身性低血压,可用于治疗败血症或细胞因子诱导的全身性低血压以恢复对效应的血管敏感性 的α1-肾上腺素能激动剂,并且可用于抑制免疫应答,例如治疗炎症。 在一个实施方案中,某些精氨基琥珀酸合成酶活性降低剂与精氨酸拮抗剂一起用于治疗败血症或细胞因子诱导的低血压。

    • Inhibitor of the use of tetrahydrobiopterin as a cofactor for nitric oxide synthase, e.g., substituted 4-phenyl(hydropyridines) such as 1-methyl-4-(3',4'-dihydroxyphenyl)-1,2,3,6-tetrahydropyridine or, 4-(3',4'-dihydroxyphenyl)-1,2,3,6-tetrahydropyridine) or tetrahydropterin analog which does not replace tetrahydrobiopterin as a substrate for nitric oxide synthase such as (6R,S)-6,7-dimethyl-tetrahydropterin or (6R,S)-tetrahydrofolic acid or 2,4-diamino-, 2,6-diamino, or 4,6-diamino mono- or disubstituted pyrimidines or the corresponding pyrimidine-3-oxides such as 2,4-diamino-6-(diethylamino)pyrimidine, 2,4-diamino-6-piperidino-pyrimidine-3-oxide, 2,4-diamino-6-hydroxypyrimidine, 4,6-diamino-2-hydroxypyrimidine or 2,5-diamino-4,6-dihydroxypyrimidine is administered to inhibit nitric oxide synthesis from arginine in vascular cells in a subject in need of such inhibition (e.g., for prophylaxis or treatment of cytokine- or endotoxin-induced hypotension (e.g., septic shock). The latter two types are advantageously administered with nitric oxide synthase inhibitors (concurrent therapy) or to potentiate the effect of .alpha..sub.1 -adrenergic agonists in the prophylaxis or treatment of induced hypotension.
