A new discovery could pave the way for more effective cancer treatment by helping certain drugs work better inside the body. Scientists at Duke University School of Medicine, University of Texas Health Science Center at San Antonio, and University of Arkansas have found a way to improve the uptake of a promising class of cancer-fighting drugs called PROTACs, which have struggled to enter cells due to their large size.
The new method works by taking advantage of a protein called CD36 that helps pull substances into cells. By designing drugs to use this CD36 pathway, researchers delivered 7.7 to 22.3 times more of the drug inside cancer cells, making the treatment up to 23 times more potent than before, according to the study published April 17 in Cell.
Data from mouse studies shows this enhanced uptake led to stronger tumor suppression without making the drugs harder to dissolve or less stable.
