    着眼于新型非典型抗精神病药的开发,我们研究了氟哌啶醇敏感的sigma受体的N,N'-二-邻甲苯基胍(DTG,3)及其同类物的结构亲和力关系。合成了许多DTG类似物,并在豚鼠脑膜匀浆的体外放射性配体置换实验中使用了高sigma特异性放射性配体[3H] -3和[3H]-(+)-3-(3-羟苯基)进行了评估。 -N-(1-丙基)哌啶和苯环利定(PCP)受体特异性化合物[3H] -N- [1-(2-噻吩基)-环己基]哌啶和[3H]-(+)-5-甲基-10 ,11-二氢-5H-二苯并[a,d]环庚烯-5,10-亚胺。N,N'-二芳基胍对sigma受体的亲和力随邻位取代基的体积比C2H5大而增加。疏水取代基通常优于类似位置的亲水取代基。此外,电子中性取代基优于强电子给体或吸电子基团。只要胍的至少一侧带有优选基团(例如2-CH 3 C 6 H 5),通常就可以保持与σ受体的显着结合。用某些饱和的碳环(例

  • N,N'-disubstituted guanidines and their use as excitatory amino acid

    N,N'-disubstituted guanidines exhibiting a high binding affinity to phencyclidine (PCP) receptors are disclosed. These N,N'-disubstituted guanidine derivatives act as non-competitive inhibitors or glutamate-induced responses generated via the NMDA receptor by acting as blockers for the ion channel of the NMDA receptor-ion channel complex. These compounds thus exert a neuroprotective property and are useful in the therapeutic treatment of neuronal loss in hypoxia, brain or spinal cord ischemia, brain or spinal cord trauma, as well as being useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.

    hylguanidine (40) showed high affinity for the NMDA receptor ion channel site (IC50 = 36 nM vs [3H]-3) and low affinity for sigma receptors (IC50 = 2540 nM vs [3H]-5). Selectivity for the NMDA receptor ion channel sites over sigma receptors appears to be dependent upon the structure of the additional substituents on the guanidine nitrogen atoms bearing the aryl groups.

    The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein. In the process, the coupling function activity can be further increased and a rubber composition favorably having a low-heat-generation property and having good abrasion resistance can be obtained.
