由于对市售药物的抗药性的不断出现,疟疾仍然是对人类的主要威胁。合成了二十一种带有末端联苯,芳基磺酰胺或芳基砜基序的吡唑并吡喃基抑制剂,并针对叶酸循环的关键酶丝氨酸羟甲基转移酶(SHMT)进行了测试。在低纳摩尔范围(18-56 n m)的基于细胞的测定中,最佳配体可抑制靶标中的恶性疟原虫(Pf)和拟南芥(At)SHMT以及Pf NF54菌株。间日疟原虫的七个共晶体结构(Pv)SHMT的分辨率为2.2–2.6Å。我们观察到邻位取代联苯部分的扭转角对基于细胞的功效产生了前所未有的影响。在与芳基磺酰胺类似物的络合物中突出显示了磺酰基部分的特殊亲脂性,它们以它们优选的交错方向结合。在配体的构象偏好的背景下讨论了结果。

available catalyst consisting of iron dichloride in combination with 1,10‐phenanthroline catalyzes the ring‐closing C−H amination of N‐benzoyloxyurea to form imidazolidin‐2‐ones in high yields. The C−H amination reaction is very general and applicable to benzylic, allylic, propargylic, and completely non‐activated aliphatic C(sp3)−H bonds, and it also works for C(sp2)−H bonds. The surprisingly simple method

Indazole compounds for treating various diseases and pathologies are disclosed. More particularly, the present disclosure concerns the use of an indazole compound or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis, fibrotic disorders, bone or cartilage diseases, and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as genetic diseases and neurological conditions/disorders/diseases due to mutations or dysregulation of the Wnt pathway and/or of one or more of Wnt signaling components. Also provided are methods for treating Wnt-related disease states.
