A method of synthesis of 4,6-disubstituted 5-thioxo-1,2,4-triazin- 3-ones from benzothioformanilides and semicarbazide is described.And six new compounds were synthesized by this method.
A series of 3,6-disubstituted s-triazolo[3,4-b]-1,3,4-thiadiazoles have been synthesized,whose structures were determined by elemental and spectral analyses;all the new compounds showed significant antibacterial activ...A series of 3,6-disubstituted s-triazolo[3,4-b]-1,3,4-thiadiazoles have been synthesized,whose structures were determined by elemental and spectral analyses;all the new compounds showed significant antibacterial activity.展开更多
Sixteen new 1,6-disubstituted fulvenes have been prepared by acylation of cyclopentadienyl sodium and the result of preliminary pharmacological tests showed that several of them have antineoplastic activity.

In the present study we report a novel protocol for the rapid, high throughput synthesis of mononuclear 2-amino-5-cyano-4,6-disubstituted pyrimidines, adaptable to parallel synthesis for compound libraries. The overall reaction time in hrs has been reduced to 25 - 50 minutes with improved yields.展开更多
目的:分析二肽基肽酶样蛋白-6(dipeptidyl-peptidase-like protein 6,DPPX)抗体相关脑炎患者的临床特征。方法:对2016年1月—2025年2月南京医科大学附属脑科医院就诊的5例DPPX抗体相关脑炎患者的临床特点、脑电图、磁共振成像(magnetic ...目的:分析二肽基肽酶样蛋白-6(dipeptidyl-peptidase-like protein 6,DPPX)抗体相关脑炎患者的临床特征。方法:对2016年1月—2025年2月南京医科大学附属脑科医院就诊的5例DPPX抗体相关脑炎患者的临床特点、脑电图、磁共振成像(magnetic resonance imaging,MRI)及预后进行回顾性研究。结果:5例均为男性,年龄14~56岁。5例患者血清DPPX抗体均为阳性,滴度1∶100~1∶10,其中1例合并血清接触蛋白关联蛋白2(contactin-associated protein-like 2,CASPR2)抗体阳性,4例脑脊液DPPX抗体阴性,1例滴度1∶1。2例患者以行为异常起病,1例以癫痫发作起病,1例以记忆力减退起病,1例合并CASPR2抗体阳性患者以多部位游走性肌阵挛起病。4例患者头颅MRI正常,1例头颅MRI提示双侧颞叶异常信号。以癫痫发作起病的患者脑电图背景重度异常合并左前颞尖波、尖慢波频发。结论:DPPX抗体相关脑炎临床表现具有异质性,早期诊断与鉴别困难,免疫治疗有效,易复发。展开更多
