Abstract

The present inventions provides drug-drug conjugates, drug-porphyrin conjugates, nanoparticles of the conjugates, as well as modified nanoparticles having PEGylated exteriors or encapsulated by red blood cell vesicles. The conjugates, nanoparticles and nanocarriers are useful for treating cancers and other diseases, as well as for imaging diseased tissue or organs.

Claims (42)

1. A compound having the structure of:

2. A compound having the structure of:

3. A compound having the structure of:

4. A nanoparticle comprising a plurality of conjugates of claim 3 , wherein the nanoparticle comprises an interior and an exterior.

5. A method of preparing a nanoparticle of claim 4 , comprising forming a reaction mixture comprising a plurality of conjugates of claim 3 under conditions suitable for the plurality of conjugates to self-assemble and form nanoparticles.

6. A method of treating a disease or condition, comprising administering to a subject in need thereof, a therapeutically effective amount of a conjugate of claim 3 , thereby treating the disease or condition.

7. A method of treating a disease or condition via sonodynamic therapy, comprising

administering to a subject in need thereof, a therapeutically effective amount of a conjugate of claim 3 ; and

exposing the subject to a sonic wave, thereby treating the disease via sonodynamic therapy.

8. A method of imaging a tissue or organ, comprising administering to a subject to be imaged, an effective amount of a conjugate of claim 3 ,

such that the conjugate or nanoparticle concentrates in the tissue or organ; and imaging the tissue or organ using a suitable device.

9. A method of detecting a tumor in a subject, comprising

administering to the subject an effective amount of a conjugate of claim 3 ;

exposing the subject to radiation at a first wavelength; and

detecting any emitted radiation from the conjugate or nanoparticle, thereby detecting the tumor.

10. A system comprising a conjugate of claim 3 , and a laser.

11. A nanoparticle comprising a plurality of conjugates of claim 2 , wherein the nanoparticle comprises an interior and an exterior.

12. A method of preparing a nanoparticle of claim 11 , comprising forming a reaction mixture comprising a plurality of conjugates of claim 2 under conditions suitable for the plurality of conjugates to self-assemble and form nanoparticles.

13. A method of treating a disease or condition, comprising administering to a subject in need thereof, a therapeutically effective amount of a conjugate of claim 2 , thereby treating the disease or condition.

14. A method of treating a disease or condition via sonodynamic therapy, comprising

administering to a subject in need thereof, a therapeutically effective amount of a conjugate of claim 2 ; and

exposing the subject to a sonic wave, thereby treating the disease via sonodynamic therapy.

15. A method of imaging a tissue or organ, comprising administering to a subject to be imaged, an effective amount of a conjugate of claim 2 ,

such that the conjugate or nanoparticle concentrates in the tissue or organ; and imaging the tissue or organ using a suitable device.

16. A method of detecting a tumor in a subject, comprising

administering to the subject an effective amount of a conjugate of claim 2 ;

exposing the subject to radiation at a first wavelength; and

detecting any emitted radiation from the conjugate or nanoparticle, thereby detecting the tumor.

17. A system comprising a conjugate of claim 2 , and a laser.

18. A nanoparticle comprising a plurality of conjugates of claim 1 , wherein the nanoparticle comprises an interior and an exterior.

19. A method of preparing a nanoparticle of claim 18 , comprising forming a reaction mixture comprising a plurality of conjugates of claim 1 under conditions suitable for the plurality of conjugates to self-assemble and form nanoparticles.

20. A method of treating a disease or condition, comprising administering to a subject in need thereof, a therapeutically effective amount of a conjugate of claim 1 , thereby treating the disease or condition.

21. A method of treating a disease or condition via sonodynamic therapy, comprising

administering to a subject in need thereof, a therapeutically effective amount of a conjugate of claim 1 ; and

exposing the subject to a sonic wave, thereby treating the disease via sonodynamic therapy.

22. A method of imaging a tissue or organ, comprising administering to a subject to be imaged, an effective amount of a conjugate of claim 1 ,

such that the conjugate or nanoparticle concentrates in the tissue or organ; and imaging the tissue or organ using a suitable device.

23. A method of detecting a tumor in a subject, comprising

administering to the subject an effective amount of a conjugate of claim 1 ;

exposing the subject to radiation at a first wavelength; and

detecting any emitted radiation from the conjugate or nanoparticle, thereby detecting the tumor.

24. A system comprising a conjugate of claim 1 , and a laser.
