  • Publication number: 20240374763
    Abstract: A method of detecting drug-resistant cancer in a subject is described. The method includes contacting a tissue of the subject with an effective amount of a molecular probe, detecting the amount of the molecular probe present in the tissue, comparing the amount of molecular probe detected to a control value, and detecting drug-resistant cancer in the subject if the amount of the molecular probe present in the tissue is higher than the control value. The molecular probe includes the following formula: P-L-C wherein P is a EDB-FN targeting peptide, C is a contrast agent; and L is a non-peptide linker that covalently links the peptide to the contrast agent. Methods of monitoring the treatment of drug resistant cancer are also described.
