The breast cancer resistance protein (BCRP, ABCG2) is among the latest discovered ABC proteins to be involved in MDR phenotype and for which only few inhibitors are known. In continuing our program aimed at discovering efficient multidrug resistance modulators, we conceived and synthesized new
The breast cancer resistance protein ABCG2 confers cellular resistance to irinotecan (CPT-11) and its active metabolite SN-38. We utilised ABCG2-expressing xenografts as a model to evaluate the ability of a non-toxic ABCG2 inhibitor to increase intracellular drug accumulation. We assessed the
In the past decades, the tricyclic acridone ring system has become a focus of major research by medicinal chemists due to the biological significance of this moiety in drug design and discovery. Acridone has substantial bio-potential since it performs crucial functions, including antibacterial,
OBJECTIVE
To investigate the anti-tumor effect of acridone against breast cancer in vivo and provide a therapeutic agent for treatment of breast cancer.
METHODS
The nude mice xenografted tumor model was established by MCF-7 cells. The mice were randomly divided into four groups. The mice in each
The anticancer activity of acridone derivatives has attracted increasing interest, therefore, a variety of substituted analogs belonging to this family have been developed and evaluated for their anti-cancer properties. A series of N-alkyl-acridones 1-6 and
Based on the molecular modelling studies, a rational modification of the lead molecule was made to develop highly potent compounds showing anti-cancer activity against human breast cancer cell lines MCF 7, MDA-MB-468 and T-47D. The most potent compounds have Log P and total polar surface area
In a quest for finding potent cytotoxic molecules, we have designed and synthesized a new scaffold by tagging quinazolinones with an acridone moiety. The new acridone-4-carboximide derivatives were evaluated for their cytotoxic potentials against the MCF7 breast cancer cell line and three colon
Hybrid systems of acridones with substituted pyrimidines were designed with an objective of discovering next generation anticancer agents targeting multiple mechanisms in the cancer cell. Hybrid compounds were synthesized by simple and convenient methods in the lab, characterized by NMR and Mass
A series of N10-substituted-2-methyl acridone derivatives are synthesized and are examined for its ability to reverse P-glycoprotein (P-gp) mediated multidrug resistance (MDR) in breast cancer cell lines MCF-7 and MCF-7/Adr. The structural requirement of in-vitro anti-cancer and reversal of drug
Eleven novel acridone derivatives were synthesized and evaluated for their anticancer activity against 60 human cancer cell lines. Five compounds 8b, 8d, 8g, 8h, and 8k displayed very good in vitro antiproliferative activities well over 95% of the panels. The most active compound is 8k (5,
A series of 2-fluoro N(10)-substituted acridone derivatives with varying alkyl side chain length with propyl, butyl substitution, and a tertiary amine group at the terminal end of the alkyl side chain were synthesized and screened against cancer cell lines SW 1573, SW 1573 2R 160 (P-gp substrate)
Overexpression of P-glycoprotein (P-gp) leads to the emergence of multidrug resistance (MDR) in cancer treatment. Acridones have the potential to reverse MDR and sensitize cells. In the present study, we aimed to elucidate the chemosensitization potential of acridones by employing various molecular
A new series of 9(10H)-acridinone-1,2,3-triazole derivatives were designed, synthesized and evaluated for their cytotoxic activity against human breast cancer cell lines. The acridone skeleton was prepared through the Ullman condensation of 2-bromobenzoic acid and anilines. Subsequently, it was
This review describes the breast cancer resistance protein ABCG2 through its structure, functional roles and involvement in cell multidrug resistance, especially in cancer cells resistance to chemotherapeutics. The different types of known inhibitors are described, some being non-selective, since
Drug resistance in cancer is an unmet medical challenge and a major drawback for the failure of many chemotherapeutic drugs. Search for targeted, effective drug with minimum toxicity is an urgent need. Acridone which is an alkaloid derivative has been attributed as molecule in reversing drug
