Abstract
The latest global cancer data statistics report shows that cancer poses a serious threat to human life and health; The number of new cancer and death cases worldwide is severe. Molecular hybridization is considered an effective strategy for developing new anti-cancer drugs. Curcumin (Cur) is a natural active compound containing Michael receptors that target thioredoxin reductase (TrxR). Fluorouracil (5-FU) is the first anti-metabolic drug synthesized based on certain assumptions for tumor treatment, acting on thymidylate synthase (TS). This study synthesized a series of novel hybrid derivatives of Cur and 5-FU, and evaluated their anti-tumor cell proliferation effects. Several compounds with good cytotoxic activity against tumor cells were discovered; and they exhibited high selectivity towards A549 cells, compared to normal THLE cells. Among them, the hybrid derivative F-4 has the best anti-proliferative activity in tumor cells. F-4 can target TrxR, increase reactive oxygen species levels in tumor cells, and lead to tumor cell apoptosis, which may be related to the Michael receptor structure in the chemical structure of F-4; F-4 can also target TS, leading to cell cycle arrest in G0/G1 phase, which may be related to the 5-FU structure in the chemical structure of F-4. Moreover, F-4 can effectively exert anti-tumor activity in mice, significantly reduce tumor volume and weight, and has low toxic side effects. These results indicate that Cur-5-FU hybrid derivative F-4 is a novel lead compound with in vivo anti-tumor activity and minimal side effects, which deserves further investigation.
期刊介绍:
Biochemical Pharmacology publishes original research findings, Commentaries and review articles related to the elucidation of cellular and tissue function(s) at the biochemical and molecular levels, the modification of cellular phenotype(s) by genetic, transcriptional/translational or drug/compound-induced modifications, as well as the pharmacodynamics and pharmacokinetics of xenobiotics and drugs, the latter including both small molecules and biologics.
The journal''s target audience includes scientists engaged in the identification and study of the mechanisms of action of xenobiotics, biologics and drugs and in the drug discovery and development process.
All areas of cellular biology and cellular, tissue/organ and whole animal pharmacology fall within the scope of the journal. Drug classes covered include anti-infectives, anti-inflammatory agents, chemotherapeutics, cardiovascular, endocrinological, immunological, metabolic, neurological and psychiatric drugs, as well as research on drug metabolism and kinetics. While medicinal chemistry is a topic of complimentary interest, manuscripts in this area must contain sufficient biological data to characterize pharmacologically the compounds reported. Submissions describing work focused predominately on chemical synthesis and molecular modeling will not be considered for review.
While particular emphasis is placed on reporting the results of molecular and biochemical studies, research involving the use of tissue and animal models of human pathophysiology and toxicology is of interest to the extent that it helps define drug mechanisms of action, safety and efficacy.
