Crystal structure analysis of the title compound, C13H12CINO, reveals three crystallographically independent molecules in the asymmetric unit. The main conformational difference between these molecules is the orientation of the phenyl rings with respect to the pyrrole rings. The coplanar arrangement of the aldehyde groups attached to the pyrrole rings influences the pyrrole-ring geometry. The C2-C3 and N1-C5 bonds are noticeably longer than the C4-C5 and N1-C2 bonds. Two independent molecules of the title compound form dimers via intermolecular C-H...O hydrogen bonds [D...A = 3.400 (3) A and D-H...A = 157°]. The perpendicular orientation of the phenyl and pyrrole rings of one independent molecule and its symmetry-related molecule allows C-H...π interactions, with an H...centroid distance of 2.85 A and a C-H...π angle of 155°. The distances between the H atom and the pyrrole-ring atoms indicate that the C-H bond points towards one of the bonds in the pyrrole ring.

High affinity and selective S1P4 receptor (S1P4-R) small molecule agonists may be important proof-of-principle tools used to clarify the receptor biological function and effects to assess the therapeutic potential of the S1P4-R in diverse disease areas including treatment of viral infections and thrombocytopenia. A high-throughput screening campaign of the Molecular Libraries-Small Molecule Repository was carried out by our laboratories and identified (2Z,5Z)-5-((1-(2-fluorophenyl)-2,5-dimethyl-1H- pyrrol-3-yl)methylene)-3-methyl-2-(methylimino) thiazolidin-4-one as a promising S1P4-R agonist hit distinct from literature S1P4-R modulators. Rational chemical modifications of the hit allowed the identification of a promising lead molecule with low nanomolar S1P4-R agonist activity and exquisite selectivity over the other S1P 1-3,5-Rs family members. The lead molecule herein disclosed constitutes a valuable pharmacological tool to explore the effects of the S1P4-R signaling cascade and elucidate the molecular basis of the receptor function.
