Indolinone based phosphoinositide-dependent kinase-1 (PDK1) inhibitors. Part 1: Design, synthesis and biological activity
摘要:
HTS screening identified I with micromolar inhibitory activity against PDK1. Optimization of 1 afforded 4i (BX-517) which has single-digit nanomolar activity against PDK1 and excellent selectivity against PKA. (C) 2007 Elsevier Ltd. All rights reserved.

Attempts to synthesize complexes of Fe and Mn(II) with 2-amidopyrrolyl ligands (N–O) were unsuccessful, and only small amounts of the trivalent tris complexes M(N–O)3 were detected, although unusually in the case of Fe(III) a fac structure is observed. In contrast the 2-benzoylpyrrolyl systems give M(II) complexes, and in all instances thus far where Na+ is present, a scorpionate fac-[MII(N–O)3]− unit
尝试合成具有2-酰胺基吡咯烷配体(N–O)的Fe和Mn(II)的配合物,并且仅检测到少量的三价tris配合物M(N–O)3,尽管在Fe情况下不常见(III)观察到fac结构。相反,2-苯甲酰基吡咯基系统生成M(II)配合物,并且在迄今为止存在Na +的所有情况下,蝎子的fac- [M II(N–O)3 ] -单元自组装成三明治阴离子[M II(N–O)3 Na(O–N)3 M II ] -其中中心金属通过芳基单元的互指而有效地包封。通过使用2-(4-吡啶基)吡咯基酰胺配体容易地制备延伸结构。当使用Li +时,蝎形配体不组装,而是[M(N–O)2 ]单元提供菱形2D网格。Fe系统显示120 K时的自旋交叉。

[Cp*M(μ-Cl)Cl]2 (M = Ir, Rh), firstly with AgOTf to abstract chloride ions and then with simple pyridyl-substituted ligands—pyridyldipyrromethene (HL1), pyridin-4-yl (1H-pyrrol-2-yl)methanone (HL2) and pyridine-4-carbohydrazide (HL3)—resulting in the formation of the tetranuclear 32-membered metallacycles [(Cp*Ir)(L1)]4(OTf)4 (2a) and [(Cp*Rh)(L1)]4(OTf)4 (2b), and the 28-membered metallacycles [(Cp*Ir)(L2)]4 (OTf)4
