The di-aryl-aldimines 3a and 3b were synthesized using 2-hydroxy-1-naphthaldehyde 1a or 9-phenanthrenecarboxaldehyde 1b reacted with 1-aminonaphthalene 2. Analysis of molecular packing using Hirshfeld calculations showed that C-H...pi and pi-pi stacking interactions were the most important. The calculated electronic aspects and NMR chemical shifts correlated well with experimental data. Compounds 3a and 3b exhibited anticancer properties, inhibiting the growth of cancer cells and affecting DNA structure and hormone production.
The di-aryl-aldimines 3a and 3b have been synthesized, respectively, by reaction of 2-hydroxy-1-naphthaldehyde 1a or 9-phenanthrenecarboxaldehyde 1b with 1-aminonaphthalene 2. Careful analysis of molecular packing at both qualitative and quantitative levels has been performed using Hirshfeld calculations. In both compounds, the C-H...pi and pi-pi stacking interactions are the most important. In case of 3a, the H...H, H...C and C...C contacts contributed significantly by 46.2, 36.0 and 7.0%, respectively. The corresponding values in case of 3b, are 44.4-47.7, 43.8-50.1 and 3.0-6.2%, respectively. The electronic aspects and NMR chemical shifts have been calculated using DFT. In both compounds, high correlation coefficients between the calculated and experimental chemical shifts have been obtained. Compounds 3a and 3b anticancer qualities prevent the development of cancer cells in the HepG2 liver cell line and the MCF-7 breast cell line, respectively. The development of molecular docking modules used components 3a and 3b against topoisomerase in liver cancer and aromatase cytochrome P450 in breast cancer receptor protein. Compounds 3a and 3b were found to have the largest influence on DNA structural alterations and inhibit the production of estrogen and progesterone in molecular docking studies.
