    • This invention is related to carbocyclic and heterocyclic substituted semicarbazones and thiosemicarbazones represented by Formula I: or a pharmaceutically acceptable salt or prodrug thereof, wherein: Y is oxygen or sulfur; R1, R21, R22 and R23 are independently hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, haloalkyl, aryl, aminoalkyl, hydroxyalkyl, alkoxyalkyl or carboxyalkyl-82-; or R22 and R23, together with the N, form a heterocycle; A1 and A2 are independently aryl, heteroaryl, saturated or partially unsaturated carbocycle or saturated or partially unsaturated heterocycle, any of which is optionally substituted; X is one or O, S, NR24, CR25R26, C(O), NR24C(O), C(O)NR24, SO, SO2 or a covalent bond; where R24, R25 and R26 are independently hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, haloalkyl, aryl, aminoalkyl, hydroxyalkyl, alkoxyalkyl or carboxyalkyl. The invention also is directed to the use of carbocycle and heterocycle substituted semicarbazones and thiosemicarbazones for the treatment of neuronal damage following global and focal ischemia, for the treatment or prevention of neurodegenerative conditions such as amyotrophic lateral sclerosis (ALS), for the treatment and prevention of otoneurotoxicity and eye diseases involving glutamate toxicity and for the treatment, prevention or amelioration of pain, as anticonvulsants, and as antimanic depressants, as local anesthetics, as antiarrhythmics and for the treatment or prevention of diabetic neuropathy and urinary incontinence.
    • 本发明涉及由式I表示的碳环和杂环取代的缩氨基脲和缩氨基硫脲或其药学上可接受的盐或前药,其中:Y是氧或硫; R1,R21,R22和R23独立地是氢,烷基,环烷基,烯基,炔基,卤代烷基,芳基,氨基烷基,羟基烷基,烷氧基烷基或羧基烷基-82-。 或R 22和R 23与N一起形成杂环; A1和A2独立地是芳基,杂芳基,饱和或部分不饱和的碳环或饱和或部分不饱和的杂环,其中任何一个任选被取代; X是1或O,S,NR 24,CR 25 R 26,C(O),NR 24 C(O),C(O)NR 24,SO,SO 2或共价键; 其中R 24,R 25和R 26独立地是氢,烷基,环烷基,烯基,炔基,卤代烷基,芳基,氨基烷基,羟基烷基,烷氧基烷基或羧基烷基。 本发明还涉及使用碳环和杂环取代的缩氨基脲和缩氨基硫脲来治疗全身和局部缺血后的神经元损伤,用于治疗或预防神经变性疾病如肌萎缩性侧索硬化(ALS),用于治疗和预防 涉及谷氨酸毒性和治疗,预防或改善疼痛,作为抗惊厥药,以及作为局部麻醉剂,作为抗心律失常药物和用于治疗或预防糖尿病性神经病和尿失禁的抗疟药抑制剂。
