Inosine monophosphate dehydrogenase (IMPDH) is a key enzyme that is involved in the de novo synthesis of purine nucleotides. Novel 2-aminooxazoles were synthesized and tested for inhibition of IMPDH catalytic activity. Multiple analogues based on this chemotype were found to inhibit IMPDH with low nanomolar potency. One of the analogues (compound 23) showed excellent in vivo activity in the inhibition
肌苷单磷酸脱氢酶(IMPDH)是嘌呤核苷酸从头合成的关键酶。合成了新型的2-氨基恶唑,并测试了其对IMPDH催化活性的抑制作用。发现基于该化学型的多种类似物以低纳摩尔效能抑制IMPDH。一种类似物(化合物23)在抑制小鼠抗体产生和在大鼠佐剂诱发的关节炎模型中显示出出色的体内活性。
