  Synthesis and Pharmacological Evaluation of N-(2,5-Disubstituted phenyl)-N‘-(3-substituted phenyl)-N‘-methylguanidines As N-Methyl-d-aspartate Receptor Ion-Channel Blockers

  摘要：

  In the mammalian central nervous system, the N-methyl-D-aspartate (NMDA) subclass of glutamate receptors may play an important role in brain diseases such as stroke, brain or spinal cord trauma, epilepsy, and certain neurodegenerative diseases. Compounds which specifically antagonize the actions of the neurotransmitter glutamate at the NMDA receptor ion-channel site offer a novel approach to treating these disorders. CERESTAT (4, aptiganel CNS 1102) is currently undergoing clinical trial for the treatment of traumatic brain injury and stroke. Previously, we reported that analogues of N-1-naphthyl-N'-(3-ethylphenyl)-N'-methylguanidine (4) bound to the NMDA receptor ion-channel site with high potency and selectivity. Recently, molecules active at both a receptors and NMDA receptor sites were investigated. A series of substituted diphenylguanidines 6 which are structurally related to N-1-naphthyl-N'-(3-ethylphenyl)-N'-methylguanidine was prepared. Compounds containing appropriate substitution pattern in one of the phenyl rings of diphenylguanidines displayed high affinity. For example, N-(2,5-dibromophenyl)-N'-(3-ethylphenyl)-N'-methylguanidine (27b, R-2 = R-5 = Br, R-3 = C2H5) exhibited potency at both a receptors and NMDA receptor sites; 27b also showed high efficacy in vivo in a neonatal rat excitotoxicity model. Further studies indicated that substituent effects were important in this compound series, and 2,5-disubstituted phenyl was the preferred substitution pattern for high-affinity binding at NMDA receptor sites. Bromo and methylthio were the optimal substituents for the R-2 and R-5 positions of the 2,5-disubstituted phenyl group, respectively. N-(2-Bromo-5-(methylthio)phenyl)-N'-(3-ethylphenyl)- N'-methylguanidine (34b, R-2 = Br, R-5 = SMe, R-3 = C2H5) was highly active at NMDA receptor sites. We found that the binding affinity of guanidines of type 6 could be further enhanced with the appropriate substitution at R-3. Optimal activity in this series are afforded by 43b and 44b (R-2 = Cl or Br, R-5 = R-3 = SCH3). Both 43b and 44b bound to NMDA receptor sites with high potency and selectivity (K-i vs [H-3]MK-801: 1.87 and 1.65 nM, respectively); these compounds are active in vivo in various animal models of neuroprotection. The structure-activity relationships for-these compounds at the NMDA receptor ion-channel site are discussed.

The degradation rates of these chlorsulfuron derivatives were accelerated by 1.84–77.22-fold, compared to chlorsulfuron, and exhibited excellent crop safety in wheat and corn (through pre-emergence treatment). In combination with bioassay activities, acidic and alkaline soil degradation

  磺酰脲类除草剂由于其降解时间长和大规模应用可导致严重的杂草抗性。氯磺隆尤其如此，它是一种在世界范围内广泛使用的乙酰乳酸合酶抑制剂。其在土壤中的持久性往往会影响随后轮作中作物幼苗的生长，并在世界范围内造成严重的环境污染。我们的研究目标是获得具有高除草活性、快速降解时间以及良好作物安全性的氯磺隆衍生除草剂。由于氯磺隆在碱性土壤中的自然降解缓慢，基于先前报道的酸性土壤中的结果，5-取代氯磺隆类似物的降解行为（L101 - L107) 在 pH 值为 8.39 的土壤中进行了研究。实验数据表明，5-取代氯磺隆化合物可加速碱性土壤的降解速率，凸显了土壤合理可控降解的潜力。与氯磺隆相比，这些氯磺隆衍生物的降解速度加快了 1.84-77.22 倍，并且在小麦和玉米中表现出优异的作物安全性（通过芽前处理）。结合生物测定活性、酸性和碱性土壤降解以及作物安全性，得出的结论是化合物L104和L107具有乙基或甲
