Pyrimidine: A promising scaffold for optimization to develop the inhibitors of ABC transporters

Area of Science:

• Biochemistry
• Medicinal Chemistry
• Pharmacology

Background:

• Multidrug resistance (MDR) in cancer hinders chemotherapy efficacy, leading to treatment failure and recurrence.
• ATP-binding cassette (ABC) superfamily proteins contribute to MDR by effluxing chemotherapeutic drugs from tumor cells.
• Current reversal agents for MDR are limited, and understanding ABC transporter-inhibitor interactions is crucial for developing new therapies.

Purpose of the Study:

• To review pyrimidine-based inhibitors targeting ABC transporters involved in MDR.
• To summarize structure optimizations and development strategies for these inhibitors.
• To provide insights into structure-activity relationships for designing novel MDR modulators.

Main Methods:

• Literature review of pyrimidine derivatives as ABC transporter inhibitors.
• Analysis of structure-activity relationships (SAR) for identified compounds.
• Discussion of development strategies for overcoming MDR.

Main Results:

• Pyrimidine derivatives demonstrate potential in reversing ABC-mediated MDR.
• Structure optimization and SAR studies are key to enhancing inhibitor potency and selectivity.
• Several pyrimidine-based compounds show promise for further development.

Conclusions:

• Pyrimidine derivatives represent a promising class of compounds for developing novel MDR reversal agents.
• Further research focusing on SAR and rational drug design is needed to create potent, selective, and low-toxicity inhibitors.
• This review serves as a reference for medicinal chemists in the development of next-generation MDR therapies.
