neurodegeneration, and is the only approved treatment of amyotrophic lateral sclerosis (ALS), the progression of which proved to significantly slow, thus increasing somewhat average survival. Here we report the synthesis of differently functionalized 4H-3,1-benzothiazine (5–6) and 2H-1,4-benzothiazine (7) series as superior homologues of 1. Biological evaluation demonstrated that amidine 4H-3,1-benzothiazine derivatives
神经退行性疾病是与中枢神经元变性有关的疾病,其逐渐导致认知和/或运动功能的各种严重改变。目前,对于没有这样的疾病,没有任何能够阻止其进展的药物治疗。利鲁唑(1)是一种小分子,能够干扰神经退行性的多种细胞和分子机制,并且是唯一批准的肌萎缩性侧索硬化症(ALS)的治疗方法,其进展被证明显着减慢了速度,从而提高了平均存活率。这里,我们报告的不同官能化合成4 ħ苯并噻嗪-3,1(5 - 6)和2- ħ -1,4-苯并噻嗪(7)系列作为1的上等同源物。生物学评估表明,在应用于脑片的氧/葡萄糖剥夺和再灌注模型(OGD / R)中,am 4 H -3,1-苯并噻嗪衍生物5b - d可以降低谷氨酸和LDH的释放,其效价高于1。此外,提到的化合物显着降低了谷氨酸和6-羟基多巴胺(6-OHDA)诱导的神经母细胞瘤细胞的细胞毒性。另外,相同的化合物限制了两种神经元制剂中ROS的形成。最后,事实证明5c可有效抑制神经元电压依赖性Na
