  Fatty acid amide hydrolase (FAAH) has a key role in the control of the cannabinoid signaling, through the hydrolysis of the endocannabinoids anandamide and in some tissues 2-arachidonoylglycerol. FAAH inhibition represents a promising strategy to activate the cannabinoid system, since it does not result in the psychotropic and peripheral side effects characterizing the agonists of the cannabinoid receptors

  脂肪酸酰胺水解酶（FAAH）在控制大麻素信号传导中起着关键作用，通过内源性大麻素anandamide的水解以及某些组织中的2-花生四烯酸甘油酯来进行。FAAH抑制代表了激活大麻素系统的一种有前途的策略，因为它不会导致表征大麻素受体激动剂的精神和外围副作用。在这里，我们介绍一种新型的profen衍生物N的发现。-（杂芳基）-2-（4-（（2-（三氟甲基）吡啶-4-基）氨基）苯基）丙酰胺，作为FAAH抑制剂。酶法测定显示对FAAH的效力范围从纳摩尔到微摩尔，并且大多数化合物对环加氧酶的两种同工型均缺乏活性。还介绍了广泛的结构活性研究和该系列先导化合物的结合方式的定义。在大鼠和小鼠FAAH上对该系列所选化合物进行的动力学分析表明，化学结构的轻微修饰可能会影响结合模式，并导致竞争性（TPA1）或非竞争性（TPA14）抑制模式。

• Muscarinic receptor binding profile of para-substituted caramiphen analogs

  Para-substituted analogues of the antimuscarinic agent caramiphen were synthesized and evaluated for their ability to bind to the M1 and M2 subtypes of the muscarinic receptor. The purpose of the set was to look for a possible relationship in binding affinity or receptor subtype selectivity with aromatic substituent parameters such as Hammett's-sigma or Hansch's pi-values. It is felt this could be determined initially with only four properly chosen substituents. In this approach, substituents were chosen which have an extreme value for sigma and for pi, in a positive and negative direction, in all combinations. The substituents chosen for examination were amino (-sigma, -pi); 1-pyrrolidinyl (-sigma, +pi); 1-tetrazolyl (+sigma, -pi), and iodo (+sigma, +pi). It was determined in this research that caramiphen binds with high affinity (K(i) = 1.2 nM) and is selective for the M1 over M2 muscarinic receptor subtype (26-fold). An examination of para-substitution reveals that compounds with electron-withdrawing (+sigma) substituents showed M1 selectivity, while the derivatives with electron-donating groups (-sigma) were nonselective in the binding assays. On the basis of this finding, the nitro and cyano derivatives were prepared and found to be M1 selective. The +sigma derivatives showed a decrease in M2 affinity while the p-nitro and p-iodo derivatives retained approximately equal affinity as caramiphen for the M1 site. The nitro- and iodocaramiphen derivatives were as potent (M1, K(i) = 5.52 and 2.11 nM, respectively) and showed a greater selectivity of M1 over M2 binding than the M1 prototypical agent pirenzepine (M1, K(i) = 5.21 nM).
