用途: Sulfamethizole is a sulfathiazole antibacterial agent.Target: AntibacterialSulfamethizole is a sulfathiazole antibacterial agent. Sulfamethizole is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA), a substrate of the enzyme dihydropteroate synthetase. The inhibited reaction is necessary in these organisms for the synthesis of folic acid. Sulfamethizole, an inhibitor of dihydropteroate synthetase and the formation of folic acid, inhibited bioluminescence more than growth [1]. Treatment with sulfamethizole resulted in a significant reduction in bacterial counts in all samples from a susceptible strain (MIC, 128 micro g/ml) and a resistant strain (MIC, 512 micro g/ml). Infection with a sulII gene-positive strain (MIC, >2,048 micro g/ml) could not be treated with sulfamethizole, as no effect could be demonstrated in the urine, bladder, or kidneys [2]. 作用: 磺胺甲噻二唑是细菌对氨基苯甲酸(PABA)的竞争性抑制剂,PABA是二氢蝶酸合成酶的底物。 在这些生物体中,抑制反应是合成叶酸所必需的。 磺胺甲噻二唑是二氢蝶酸合成酶的抑制剂和叶酸的形成,抑制生物发光而不是生长。 用磺胺甲噻二唑处理导致来自敏感菌株(MIC,128微克/毫升)和抗性菌株(MIC,512微克/毫升)的所有样品中细菌计数的显着减少。 用sulⅡ基因阳性菌株(MIC,> 2,048微克/毫升)感染不能用磺胺甲噻二唑治疗,因为在尿液,膀胱或肾脏中没有效果。 物理化学性质: CAS号:144-82-1 常用中文名:磺胺甲二唑 常用英文名:Sulfamethizole 分子式:C9H10N4O2S2 分子量:270.331 密度:1.6±0.1 g/cm3 沸点:504.9±52.0 °C at 760 mmHg 熔点:210 °C 闪点:259.1±30.7 °C 储存条件:2-8°C |
