but play different physiological roles in vivo. Selective inhibition toward one of these enzymes is therefore of importance to regulate the corresponding bioprocess. Here ten new NAM-thiazoline derivatives were synthesized and subsequently characterized by NMR and HRMS. A preliminary bioassay showed that most of the synthesized compounds exhibited obvious selective inhibition against human O-GlcNAcase
来自智人的人O-GlcNAcase(GH 84)和人β-N-乙酰基-D-己糖胺酶(GH 20)是两个治疗性酶标靶,它们具有相同的催化机制,但在体内起着不同的生理作用。因此,对这些酶之一的选择性抑制对于调节相应的生物过程很重要。在此合成了十种新的NAM-噻唑啉衍生物,随后通过NMR和HRMS进行了表征。初步的生物测定表明,大多数合成的化合物对人O-GlcNAcase的抑制作用均强于人β-N-乙酰基-D-己糖胺酶。在所测试的化合物中,化合物7d(IC50 = 6.4 µM,hOGA; IC50> 1 mM,hHex)和7f(IC50 = 11.9 µM,hOex; IC50> 1 mM,hHex)被证明是高度选择性和有效的抑制剂。
