In the title compound, C(15)H(12)INO(2)S, the sulfonyl-bound phenyl ring forms a dihedral angle 82.84 (9)° with the indole ring system. The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O hydrogen bond. The crystal structure exhibits weak inter-molecular C-H⋯π inter-actions and π-π inter-actions between the indole groups [centroid-centroid distance between the five-membered a...

In the title compounds, C12H12N2O2, (I), and C17H14N2O2, (II), respectively, the indole rings are planar and the vinyl groups lie out of the indole planes, making dihedral angles of 33.48 (5) and 41.31 (8) degrees , respectively. In (II), the dihedral angle between the phenyl and indole ring planes is 32.06 (6) degrees . In both molecules, the double bond connecting the methylnitrovinyl group a...

Apart from the methyl group of the meth-oxy fragment, the title compound, C(15)H(12)N(2)O, is almost planar (r.m.s. deviation = 0.045 Å); the C atom deviates from the mean plane by 1.216 (1) Å. In the crystal, π-π stacking [shortest centroid-centroid separation = 3.4652 (10) Å] and C-H⋯π inter-actions occur.

In the title compound, C(25)H(23)N, the indole unit makes a dihedral angles of 79.03 (5) and 61.82 (4)° with the benzene rings. No classical hydrogen bonds are found in the crystal structure.

There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(23)H(21)NO(3)S. The indole ring system is approximately perpendicular to the sulfonyl phenyl ring in both mol-ecules [dihedral angles = 85.42 (8) and 88.30 (9)°]. C-H⋯O inter-actions between mol-ecules stabilize the crystal structure.

In the title compound, C(17)H(14)N(2)O, the dihedral angle between the indole ring system and the benzene ring is 58.41 (4)°. The crystal packing features π-π stacking [shortest centroid-centroid separation = 3.8040 (9) Å] and C-H⋯π inter-actions.

The title indole derivative, C(17)H(15)NO(3)S, crystallizes with two independent mol-ecules in the asymmetric unit. The benzene ring of the tosyl group is almost perpedicular to the indole ring in both mol-ecules, with inter-planar angles of 82.60 (5)° and 81.82 (6)°. The two mol-ecules are, as a consequence, able to form an almost centrosymmetric non-bonded dimer, in which the molecules are li...

In the title compound, C(16)H(14)ClNO(2)S, the phenyl ring makes a dihedral angle of 78.1 (1)° with the indole ring system. The mol-ecular structure is stabilized by weak intra-molecular C-H⋯O inter-actions. The crystal structure exhibits weak inter-molecular C-H⋯O, C-H⋯π and π-π [centroid-centroid distances = 3.620 (1)-3.794 (1) Å] inter-actions.

In the title compound, C(16)H(11)BrN(2), the dihedral angle between the indole ring system and the phenyl ring is 58.85 (11)°.

N-Formyl peptide receptors (FPRs) are G protein-coupled receptors (GPCRs) involved in host defense and sensing cellular dysfunction. Thus, FPRs represent important therapeutic targets. In the present studies, we screened 32 ligands (agonists and antagonists) of unrelated GPCRs for their ability to induce intracellular Ca²+ mobilization in human neutrophils and HL-60 cells transfected with human...
