| abstract |
The present invention provides a novel boron carrier compound that can be used in boron neutron capture therapy for cancer, and that can improve drug delivery system (DDS) efficiency and heighten the concentration of boron in the tumor. The present invention provides a boron cluster-modified PEG lipid derivative represented by formula (I), and a molecular assembly containing the same. (In the formula, m and n are independent and are each an integer of 1-4, q is an integer of 1-280, R 1 and R 2 are independent and are each a C8-22 hydrocarbon group.) |
