Area of Science:

  • Biochemistry
  • Enzymology
  • Pharmacology

Background:

  • Carbonyl reductases (CBRs), part of the short-chain dehydrogenases/reductases (SDR) family, are NADPH-dependent enzymes.
  • These enzymes exhibit broad substrate specificity, reducing various endogenous and xenobiotic carbonyl compounds, including prostaglandins, steroids, and polycyclic aromatic hydrocarbons.
  • CBRs are known to reduce anthracycline anticancer drugs like daunorubicin and doxorubicin, altering their pharmacological properties.

Purpose of the Study:

  • To explore the emerging roles of Carbonyl Reductases (CBRs).
  • To understand the involvement of CBRs in cellular and molecular processes.
  • To investigate the connection between CBRs and drug metabolism, resistance, mutagenesis, and carcinogenesis.

Main Methods:

  • Literature review of recent data on Carbonyl Reductases (CBRs).
  • Analysis of enzyme kinetics and substrate specificity.
  • Examination of cellular and molecular pathways involving CBRs.

Main Results:

  • Carbonyl reductases (CBRs) play a significant role in the metabolism of various carbonyl compounds.
  • CBRs reduce anticancer drugs, modifying their efficacy and side effects.
  • Emerging evidence links CBRs to crucial processes including drug resistance, mutagenesis, and carcinogenesis.

Conclusions:

  • Carbonyl reductases (CBRs) are key enzymes in xenobiotic metabolism and drug inactivation.
  • The involvement of CBRs in drug resistance, mutagenesis, and carcinogenesis highlights their importance in cancer research.
  • Further investigation into CBRs could lead to novel therapeutic strategies for cancer treatment and prevention.
