with these studies, the effect of substitution on the pyridine ring of 2f was also examined. A series of small, nonaromatic C5-substituents was also explored and revealed that the K(i) follows a well-defined correlation with the Hammett sigma(p) constant (rho = 3.01, R2 = 0.91) in which electron-withdrawing substituents enhance potency, leading to inhibitors with K(i)s as low as 400 pM (20n).

针对2f(OL-135)(一种有效的脂肪酸酰胺水解酶(FAAH)抑制剂)的结构-活性关系(SAR)进行了详细研究,其目标是恶唑的5位。对一系列取代苯衍生物(12-14)的研究表明,最佳取代位置是间位,所选成员的效价接近或超过2f。与这些研究同时,还研究了取代对2f的吡啶环的影响。还研究了一系列小的非芳香族C5取代基,发现K(i)与Hammett sigma(p)常数(rho = 3.01,R2 = 0.91)具有明确定义的相关性,吸电子取代基增强效力,导致抑制剂的K(i)s低至400 pM(20n)。
