Abstract:
The resistance of tumor cells to a broad range of anticancer agents continues to be a problem for the success of cancer chemotherapy. Multidrug resistance (MDR) is due in part to three drug transporter proteins: ABCB1/P-glycoprotein (P-gp), ABCC1/multidrug resistance protein 1 (MRP1) and ABCG2/breast cancer resistance protein (BCRP). These transporters are part of the ATP-binding cassette (ABC) superfamily, whose members function as ATP-dependent drug-efflux pumps. Their activity can be blocked by various drugs such as verapamil (calcium channel blocker) and cyclosporin A (immunosuppressive agent), etc. These compounds are called MDR modulators or reversals. This review highlights several marine natural products with reversal effect on multidrug resistance in cancer, including agosterol A, ecteinascidin 743, sipholane triterpenoids, bryostatin 1, and welwitindolinones.
Insights
Marine natural products show promise in overcoming cancer multidrug resistance (MDR). These compounds can reverse the effects of ATP-binding cassette (ABC) transporters, enhancing chemotherapy efficacy.
Area of Science:
- Biochemistry
- Pharmacology
- Marine Biology
Background:
- Tumor cell resistance to anticancer agents, known as multidrug resistance (MDR), hinders chemotherapy success.
- MDR is often mediated by ATP-binding cassette (ABC) superfamily transporters, including P-glycoprotein (P-gp), MRP1, and BCRP.
- MDR modulators, such as verapamil and cyclosporin A, can inhibit these drug-efflux pumps.
Purpose of the Study:
- To review marine natural products with the potential to reverse cancer multidrug resistance.
- To highlight specific marine compounds and their efficacy as MDR modulators.
Main Methods:
- Literature review of scientific publications on marine natural products and multidrug resistance.
- Analysis of studies investigating the reversal effects of marine compounds on cancer cell lines expressing ABC transporters.
Main Results:
- Several marine natural products exhibit MDR reversal activity.
- Examples include agosterol A, ecteinascidin 743, sipholane triterpenoids, bryostatin 1, and welwitindolinones.
- These compounds modulate the activity of key drug-efflux pumps.
Conclusions:
- Marine natural products represent a promising source of novel MDR modulators.
- Further research into these compounds could lead to improved cancer chemotherapy strategies.
- Targeting ABC transporters with marine-derived agents offers a potential avenue to overcome drug resistance.
