indole‐3‐glyoxylamide series of antiprion agents have been explored further, resulting in discovery of several newcompounds demonstrating excellent activity in a cell line model of prion disease (EC50 <10 nM). After examining a range of substituents at the para‐position of the N‐phenylglyoxylamide moiety, five‐membered heterocycles containing at least two heteroatoms were found to be optimal for the antiprion effect
进一步研究了吲哚-3-乙醛酰胺系列抗pr病毒剂之间的结构活性关系,从而发现了几种在compounds病毒疾病细胞系模型中表现出优异活性的新化合物(EC 50 <10 n M)。在检查N的对位上的一系列取代基后苯乙醛基乙酰胺部分中,含有至少两个杂原子的五元杂环被认为是抗pr病毒作用的最佳选择。尽管没有很好的耐受性,但进行了许多修饰以探讨乙醛酰胺亚结构的重要性。然而,最有效的化合物确实对微粒体代谢具有很大的稳定性,并且最活跃的文库成员在单次给药后无限期地治愈了瘙痒病感染的细胞。因此,目前的结果证实了吲哚-3-乙氧基乙酰胺是有前途的铅系列,可用于继续进行体外和体内抗病毒疾病的评估。

A facilesynthesis of 1,3,4-oxadiazoles and 1,3,4-oxadiazoles-d5 via [4 + 1] cyclization of ClCF2COONa with non-amine compounds containing amino groups is developed. Of note, this is the first time that halofluorinated compounds are used as C1 synthon to construct deuterated nitrogen-heterocyclic compounds. The current protocol features simple operation, readily accessible raw materials, wide substrate
Three series of substituted1,3,4-oxadiazoles were studied by (17)O NMR spectroscopy. Chemical shifts values were correlated with empirical Hammett parameters as well as calculated bond lengths and chemical shielding values.
15N NMR chemicalshifts of 2‐aryl‐1,3,4‐oxadiazoles were assigned on the basis of the 1H–15N HMBC experiment. Chemicalshifts of the nitrogen and carbon atoms in the oxadiazole ring correlate with the Hammett σ‐constants of substituents in the aryl ring (r2 ≥ 0.966 for N atoms). 15N NMR data are a suitable and sensitive means for characterizing long‐range electronic substituenteffects.

The present invention provides novel substituted pyrimidinyl-amines that are useful as inhibitors of protein kinases, especially c-Jun N-terminal kinases (JNK) and pharmaceutical compositions thereof and methods of using the same for treating conditions responsive to the inhibition of the JNK pathway.
