Ethyl 4'-ethenyl-2'-oxo-4-phenyl-2-(3,4,5-trimethoxy-phen-yl)spiro-[pyrrolidine-3,3'-indoline]-5-carboxyl-ate monohydrate.

ABSTRACT: In the title compound, C(31)H(32)N(2)O(6)·H(2)O, the pyrrolidine ring adopts an envelope conformation. The ethyl C atoms of the ethoxy-cabonyl group are disordered over two positions with occupancies of ca 0.80 and 0.20. Intra-molecular N-H?O hydrogen bonds form S(5) and S(6) ring motifs. Mol-ecules are linked into a three-dimensional framework by O-H?O, N-H?O and C-H?O hydrogen bonds, and by C-H?? inter-actions.

Spiro[pyrrolidine-3,3'-oxindoles] and Their Indoline Analogues as New 5-HT6 Receptor Chemotypes.

Project description:Synthetic derivatives of spiro[pyrrolidinyl-3,3'-oxindole] alkaloids (coerulescine analogues) were investigated as new ligands for aminergic G-protein coupled receptors (GPCRs). The chemical starting point 2'-phenylspiro[indoline-3,3'-pyrrolidin]-2-one scaffold was identified by virtual fragment screening utilizing ligand- and structure based methods. As a part of the hit-to-lead optimization a structure-activity relationship analysis was performed to explore the differently substituted 2'-phenyl-derivatives, introducing the phenylsulphonyl pharmacophore and examining the corresponding reduced spiro[pyrrolidine-3,3'-indoline] scaffold. The optimization process led to ligands with submicromolar affinities towards the 5-HT? receptor that might serve as viable leads for further optimization.
