• 解毒与急救

/SRP:/ 立即急救：确保已经进行了充分的中毒物清除。如果患者停止呼吸，开始人工呼吸，最好使用需求阀复苏器、袋阀面罩装置或口袋面罩，按训练操作。根据需要执行心肺复苏。立即用缓慢流动的水冲洗受污染的眼睛。不要催吐。如果发生呕吐，让患者前倾或置于左侧卧位（如果可能的话，头部向下）以保持呼吸道畅通，防止吸入。保持患者安静，维持正常体温。寻求医疗帮助。 /苯胺及其相关化合物/

/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aniline and related compounds/

  摘要：

  Phenoxy benzyl ethers are easily and quickly deprotected in the presence of ammonium formate and microencapsulated Pd(0)EnCat with the assistance of microwave irradiation. This procedure can be applied in the presence of other functional groups as well. The described protocol is particularly convenient for the preparation in a parallel and automatic fashion of libraries of compounds possessing a phenol type moiety. (c) 2006 Elsevier Ltd.

  We report the optimisation of a series of novel amide-piperidine (piperazine) derivatives using the multiple ligand approach with dopamine and serotonin receptors. Of the derivatives, compound 11 exhibited high affinity for the D2, 5-HT1A, and 5-HT2A receptors, but low affinity for the 5-HT2C and histamine H1 receptors and human ether-a-go-go-related gene (hERG) channels. In vivo, compound 11 reduced
