breakdown. The membrane-associated enzyme responsible for the synthesis of NAA, aspartate N-acetyltransferase (ANAT), has recently been purified and examined (Wang et al., Prot Expr Purif. 2016;119:11). With the availability, for the first time, of a stable and soluble form of ANAT we can now report the identification of initial inhibitors against this biosynthetic enzyme, obtained from the screening of
卡纳万病是一种致命的神经系统疾病,由N-乙酰-1-天冬氨酸(NAA)代谢缺陷引起。最近的工作表明,这种疾病的破坏性症状与在这些患者中观察到的NAA水平升高有关,这是由于天冬氨酸酰化酶的突变形式无法充分催化其分解而导致的。负责NAA合成的膜相关酶,天冬氨酸N-乙酰基转移酶(ANAT),最近已被纯化和检测(Wang等人,Prot Expr Purif。2016; 119:11)。有了稳定和可溶形式的ANAT,我们现在首次可以报告对这种生物合成酶的初步抑制剂的鉴定,该抑制剂是从几个重点化合物库的筛选中获得的。这些中度结合化合物的两个核心结构随后进行了优化,这些系列中最有效的抑制剂具有针对ANAT的亚微摩尔抑制常数(K i值)。通过抑制ANAT来减慢NAA的产生将降低这种代谢产物的升高水平,并有可能作为缓解Canavan疾病症状的治疗选择。
