A Tasquinomod-loaded dopamine-modified pH sensitive hydrogel is effective at inhibiting the proliferation of KRAS mutant lung cancer cells

Hydrogels can maintain a high local drug concentration during treatments and may be useful to local targeting diseased areas. We propose a pH sensitive hydrogel consisting of polyvinylpyrrolidone (PVP) and chitosan as a new treatment method for KRAS mutant lung cancer. Addition of dopamine improved the drug loading and release effects of this hydrogel. We demonstrate that Tasquinimod-loading of this dopamine-modified pH sensitive hydrogel is more effective than Tasquinimod alone for inhibiting the proliferation of KRAS mutant lung cancer cells. Combina-tion of conventional drugs with hydrogels may thus provide a new treatment modality for lung cancer.
