4-(3-Alkyl-2-oxoimidazolidin-1-yl)-N-phenylbenzenesulfonamides as new antimitotic prodrugs activated by cytochrome P450 1A1 in breast cancer cells
摘要:
The role and the importance of the sulfonate moiety in phenyl 4-(2-oxo-3-alkylimidazolidin-1-yl) benzenesulfonates (PAIB-SOs) were assessed using its bioisosteric sulfonamide equivalent leading to new cytochrome P450 1A1 (CYP1A1)-activated prodrugs designated as 4-(3-alkyl-2-oxoimidazolidin-1-yl)-N-phenylbenzenesulfonamides (PAIB-SAs). PAIB-SAs are active in the submicromolar to low micromolar range showing selectivity toward CYP1A1-expressing MCF7 cells as compared to cells devoid of CYP1A1 activity such as MDA-MB-231 and HaCaT cells. The most potent, PAIB-SA 13, bearing a trimethoxyphenyl group on ring B blocks the cell cycle progression in G2/M phase, disrupts the microtubule dynamics and is biotransformed by CYP1A1 into CEU-638, its potent antimicrotuble counterpart. Structure-activity relationships related to PAIB-SOs and PAIB-SAs evidenced that PAIB-SOs and PAIB-SAs are true bioisosteric equivalents fully and selectively activatable by CYP1A-expressing cells into potent antimitotics.
