چکیده
In the title mol-ecule, C26H17N3O2, both indole ring systems are essentially planar, with maximum deviations of 0.019 (2) and 0.033 (1) Å for the N atoms, and form dihedral angles of 34.40 (9) and 45.06 (8)° with the essentially planar pyrrole ring [maximum deviation = 0.020 (2) Å]. The dihedral angle between the two indole ring systems is 58.78 (6)°. In the crystal, mol-ecules are connected by pairs of N-H⋯O hydrogen bonds, forming inversion dimers and generating R 2 (2)(8) rings. Weak π-π stacking inter-actions, with a centroid-centroid distance of 3.983 (2) Å, are also observed.

There are four molecules in the asymmetric unit of the title compound, C(16)H(17)N(3)O(4), in which the dihedral angles between the indole ring system and maleimide ring are 4.5 (3), 8.3 (3), 8.4 (2) and 10.4 (2)°. In the crystal, mol-ecules are linked by numerous N-H⋯O and O-H⋯O hydrogen bonds, generating a three-dimensional network.
متن کامل3-(2,4-dichlorophenyl)-4-(1-methyl-1H-indol-3-yl)-1H-pyrrole-2,5-dione (SB216763), a glycogen synthase kinase-3 inhibitor, displays therapeutic properties in a mouse model of pulmonary inflammation and fibrosis.
Glycogen synthase kinase (GSK)-3 modulates the production of inflammatory cytokines. Because bleomycin (BLM) causes lung injury, which is characterized by an inflammatory response followed by a fibrotic degeneration, we postulated that blocking GSK-3 activity with a specific inhibitor could affect the inflammatory and profibrotic cytokine network generated in the BLM-induced process of pulmonar...
متن کاملThe glycogen synthase kinase inhibitor 3-(2,4-dichlorophenyl)-4-(1-methyl-1H-indol-3-yl)-1H-pyrrole-2,5-dione (SB216763) is a partial agonist of the aryl hydrocarbon receptor.
Kinase inhibitors are frequently used tools in signal transduction research. 3-(2,4-Dichlorophenyl)-4-(1-methyl-1H-indol-3-yl)-1H-pyrrole-2,5-dione (SB216763), a potent inhibitor of glycogen synthase kinase 3beta (GSK3beta), is frequently used to activate beta-catenin signaling by mimicking the action of Wnt molecules. beta-Catenin is a crucial player in the regulation of hepatic drug metabolis...
متن کاملCatalyst and Solvent-Free Microwave Assisted Expeditious Synthesis of 3-Indolyl-3-hydroxy Oxindoles and Unsymmetrical 3,3-Di(indolyl)indolin-2-ones
A simple and efficient method for the synthesis of 3-indolyl-3-hydroxy oxindoles and unsymmetrical 3,3-di(indolyl)indolin-2-ones using microwave irradiation without catalyst and solvent is described. A series of 3-indolyl-3-hydroxy oxindoles and unsymmetrical 3,3-di(indolyl)indolin-2ones have been synthesized in very short reaction times of 5 and 10 minutes and in yields ranging from 31% to 98%...
متن کاملThe activation of M1 muscarinic receptor signaling induces neuronal differentiation in pyramidal hippocampal neurons.
Muscarinic receptors have been proposed to play an important role during brain development by regulating cell survival, proliferation, and differentiation. This study investigated the effect of muscarinic receptor activation on prenatal rat hippocampal pyramidal neuron differentiation and the signal transduction pathways involved in this effect. The cholinergic agonist carbachol, after 24 h in ...
