Design, synthesis and cytotoxic properties of novel 1-[4-(2-alkylaminoethoxy)phenylcarbonyl]-3,5-bis(arylidene)-4-piperidones and related compounds
摘要:
The 3,5-bis(arylidene)-4-piperidones I contain the 1,5-diaryl-3-oxo-1,4-pentadienyl pharmacophore which is considered to interact at a complementary binding site in susceptible neoplasms. The hypothesis was formulated that the presence of an acyl group attached to the piperidyl nitrogen atom in series 1 may interact with an additional binding site thereby enhancing cytotoxic potencies. This concept led to the synthesis of various N-acyl-3,5-bis(arylidene)-4-pipetidones 3-7 many of which displayed significant cytotoxicity towards a variety of cancer cell lines. A comparison of the potencies between the compounds in series I and the related nonquaternary analogues 3-6 revealed that in approximately half of the comparisons made, the N-acyl analogues had increased potencies.

The 1-[4-(2-aminoethoxy) phenylcarbonyl]-3,5-bis-(benzylidene)-4-oxopiperidines 5-8 are a novel cluster of highly potent P-glycoprotein dependent multidrug resistance (MDR) revertants. Using a concentration of 4 mu g/mL, these compounds possess 11-43 times the potency of verapamil in reversing MDR in murine L-5178 lymphoma cells transfected with the human MDR1 gene. Structure-activity relationships reveal that the attachment of the N-aroyl group to various 3,5-bis(benzylidene)-4-piperidones is essential for MDR reversal to occur. In terms of potencies, the 1-piperidinyl group is the preferred terminal amine while the 4-methyl and 4-chloro substituents are the optimal groups for placement in the benzylidene aryl rings.
