Effect of the selected phenolic and flavonoid compounds of black pepper and caraway seeds on prostate cells

In this study, the effect of selected phenolic and flavonoid compounds of black pepper and caraway seeds on prostate cells (PNT1A, 22RV1 and PC3) was observed. Synthetic standards of 3,4-dihydroxybenzaldehyde and naringenin chalcone, identified previously by HPLC-MS in black pepper seeds extracts, and neochlorogenic acid and apigenin, identified in caraway seeds extracts, were applied. For the evaluation of the potential inhibitory effect of selected compounds on PNT1A, 22RV1 and PC3 cells, the clonogenic assay and the microscopic observation of cells were done. The results of clonogenic assay showed that phenolic compounds had the strongest inhibitory effect on 22RV1 and PC3 cells, while the flavonoid compounds had the strongest inhibitory effect on PNT1A cells
