Nowadays, chemotherapy is commonly used for treating cancer while multidrug resistance (MDR) remains a major problem. Dr. Chow and Prof. Chan's team has designed small molecules to reverse this process. Membrane proteins P-glycoprotein (P-gp) and Breast Cancer Resistance Protein (BCRP) pump drugs out of cancer cells and reduce chemotherapy efficacy. The team has designed, synthesized and characterized novel diet-derived flavonoid dimers which can target P-gp and BCRP's dimeric structure. Due to the unique design of dimeric structure which can specifically bind to the pseudodimeric P-gp and BCRP, these flavonoid dimers can inhibit P-gp and BCRP, and reverse cancer drug resistance with very high potency (inhibiting BCRP at < 1 nM) and low toxicity (therapeutic index of 1x105).
Let us congratulate Dr. Chow and Prof. Chan on receiving this award.
