The invention provides a compound of Formula I, an isomer, a pharmaceutically acceptable salt, or a solvate thereof, and use thereof in manufacture of a medicament for preventing and/or treating a drug-resistant tumor or disease or disorder caused by a drug-resistant bacterium, or use thereof in manufacture of a medicament for preventing and/or treating a tumor, a neurodegenerative disease, an allogeneic graft rejection, or an infection-associated disease or disorder; preferably, the tumor, neurodegenerative disease, allogeneic graft rejection, or infection-associated disease or disorder is a disease or disorder caused by Heat shock protein 70 (Hsp70). The compounds of the invention, which are a class of Hsp70 inhibitors having a novel structure and a high activity, solve the problem concerning drug resistance of tumors, enhance the effect of treating tumors, and provide a new medical strategy for treatment of tumors in clinic. ##STR00001##

Provided herein is the design and synthesis of novel molecular rotor fluorophores useful for detection of amyloid or amyloid like proteins. The fluorophores are designed to exhibit enhanced fluorescence emission upon associating with amyloid or amyloid like proteins as compared to unbound compound. Also disclosed herein are methods for treating diseases associated with amyloid or amyloid like proteins.
