چکیده
The title mol-ecule, C(26)H(22)N(4)S, is composed of three main parts, viz. a triphenyl-amine group is connected to a phenyl ring by a thio-semicarbazone moiety. The C= N double bond has an E conformation. The crystal packing is dominated by strong hydrogen bonds through the thio-semicarbazone moiety, with pairs of N-H⋯S hydrogen bonds linking the mol-ecules to form inversion dimers with an R(2) (2)(8) ring motif. An intra-molecular N-H⋯N hydrogen bond is also present, generating an S(5) ring motif. Although the structure contains four phenyl rings, π-π stacking inter-actions are not formed between them, probably due to the conformation adopted by the triphenyl-amine group. However, a weak π-π stacking inter-action is observed between the phenyl ring and the delocalized thio-semicarbazone moiety.

In the title compound, C(19)H(15)NO, the N atom adopts an approximately trigonal-planar geometry, lying 0.07 (1) Å from the plane defined by its three neighbouring C atoms. The two phenyl rings and the benzaldehyde group form dihedral angles of 53.0 (1)/47.2 (1) and 29.0 (1)°, respectively, with this central plane.

The effects of benzaldehyde, which has been found in figs as a carcinostatic element, were studied on the uptake of nucleosides, 2-deoxy-D-glucose, and amino acids into simian virus 40-transformed rat fibroblast cells (SV40-transformed cells) and into the parent normal cells (normal cells). Benzaldehyde, at the concentrations of 25 to 100 microgram/ml at which the selective growth inhibition ag...
