halomethylketone moiety to reversibleinhibitors turned them into irreversible inhibitors with IC50 values in the nanomolar range. Overall, the results point out that these compounds might be useful pharmacological tools to explore physiological and pathological processes related to signaling pathways regulated by GSK-3 opening new avenues for the discovery of novel GSK-3 inhibitors.

data showed that compound4 j was able to induce necrosis and apoptosis in trypomastigotes. Analysis by scanning electron microscopy showed that T. cruzi trypomastigote cells treated with compounds 3 h, 3 t, and 4 j at IC50 concentrations promoted changes in the shape, flagella, and surface of the parasite body similar to those observed in benznidazole‐treated cells. The compounds with the highest
恰加斯病和疟疾是两种被忽视的热带病 (NTD),在 149 个国家的热带和亚热带地区流行。由于无症状感染者的移民,恰加斯也出现在欧洲、美国和澳大利亚。在缺乏有效疫苗的情况下,两种疾病的控制都依赖于化疗。然而,寄生虫耐药性的出现正在使目前可用的药物过时。因此,开发新分子至关重要。邻苯二甲酰亚胺、缩氨基硫脲和 1,3-噻唑已被用作支架以获得抗疟原虫和抗克氏锥虫药物。在此,我们展示了 24 种邻苯二甲酰亚胺-缩氨基硫脲 ( 3 a - x ) 和 14 种邻苯二甲酰亚胺 - 噻唑 ( 4 a -n ) 和相应的针对克氏锥虫、恶性疟原虫的生物活性,以及针对哺乳动物细胞系的细胞毒性。其中一些化合物在 RAW 264.7 细胞中以低细胞毒性浓度显示出对T. cruzi 的有效抑制。活性最强的化合物3 t (IC 50 =3.60 μM)、3 h (IC 50 =3.75 μM) 和4 j (IC 50

A new type of alpha-phthalimide ketones was hydrogenated in excellent enantioselectivity by using a Ru-(C3-TunePhos) complex as the catalyst. Up to 10 000 turnovers have been achieved in more than 99% ee in the hydrogenation reaction. A dynamic kinetic resolution study for the synthesis of threonine was performed, and high anti selectivity (>97:3) was observed for the first time. An efficient method
以Ru-(C3-TunePhos)配合物为催化剂,以优异的对映选择性氢化一种新型α-邻苯二甲酰亚胺酮。在氢化反应中,超过 99% ee 的转化率达到了 10 000 次。对苏氨酸的合成进行了动态动力学拆分研究,首次观察到了高抗选择性(>97:3)。已开发出一种合成对映体纯氨基醇的有效方法。
