Various 1-(amino-N-arylmethanethio)-3-(1-substituted benzyl-2, 3-dioxoindolin-5-yl) urea (5a–p) were designed keeping in view the structural requirements suggested in the pharmacophore model for anticonvulsant activity. Their in vivo anticonvulsant screenings were performed by two most adopted seizure models, maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole (scPTZ). Compound 5f
考虑到抗惊厥药药效团模型中建议的结构要求,设计了各种 1-(氨基-N-芳基甲硫基)-3-(1-取代苄基-2, 3-二氧吲哚-5-基)脲 ( 5a – p )活动。他们的体内抗惊厥药筛查是通过两种最常用的癫痫发作模型进行的,即最大电休克癫痫发作 (MES) 和皮下戊四唑 (scPTZ)。发现化合物5f在MES筛选中具有活性,而化合物5h、5i、5k和5l在两种筛选中均显示出显着的抗惊厥活性并且没有任何神经毒性。化合物5h和5i在 300 mg/kg 时显示出对 MES 和 scPTZ 筛选的显着保护。化合物5i在 100 mg/kg 的剂量下也显示出对 MES 筛选的保护作用。在 6 Hz 筛选中,这两种化合物显示出显着的保护作用,并成为未来研究的先导化合物。
