Abstract

The present invention is directed to new 5-ALA derivatives, particles and formulation thereof, related methods of preparation and methods of use thereof. In particular, the invention relates to compounds of the invention, particles and formulation thereof useful in the treatment of a cancer and/or the diagnosis of a cancer cell such as in photodynamic therapy or photodynamic diagnosis.

First claim

We claim:

1. A method of treating or repressing a disease or disorder selected from hyperproliferative conditions selected from tumors and a metastatic and non-metastatic cancer selected from colon cancer, rectal cancer, breast cancer, mama carcinoma, lymphoma, brain cancer, ovarian cancer, non-small cell lung cancer, colorectal carcinoma, glioblastoma, gastric cancer, bronchus cancer, pancreatic cancer, urinary bladder cancer, hepatic cancer, skin cancer, non-melanoma skin cancer, oesophageal cancer, oral cancer, duodenal cancer, cervix cancer, uterus cancer, kidney cancer and prostate cancer, a skin disorder selected from psoriasis, skin cancer and actinic keratosis, infectious diseases, inflammatory diseases selected from Morbus Crohn, arthritis, rheumatoid arthritis, Barrett's oesophagus and arterial restenosis, said method comprising administering in a subject in need thereof a therapeutically effective amount of a compound according to Formula (I), a pharmaceutically acceptable salt thereof, a particle formed by said compound or a pharmaceutical formulation of said compound and exposing cells of said disease or disorder to light:

wherein B is a biocompatible non-peptidic moiety cleavable by ubiquitous enzymes present in mammalian cells, L is a biocompatible self-removable linker and R 1 is selected from H, optionally substituted C 1 -C 30 alkyl, optionally substituted C 2 -C 30 alkenyl, optionally substituted C 2 -C 30 alkynyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heteroaryl and optionally substituted aryl C 1 -C 6 alkyl and n is an integer selected from 0 and 1, wherein said biocompatible non-peptidic moiety cleavable by ubiquitous enzymes present in mammalian cells is not an acetyl group.

2. The method according to claim 1 , wherein the said disorder is a skin disorder selected from psoriasis, skin cancer and actinic keratosis.

3. The method according to claim 1 , wherein the said disorder is an infectious disease selected from a viral infection, a bacterial infection and a fungal infection.

4. The method according to claim 1 , wherein said compound is administered topically, orally or systemically.

5. The method according to claim 1 , wherein said method further comprises a step of administering to said subject a metal ion or a radioisotope of said metal ion before the step of light exposure.

6. The method according to claim 1 , wherein n is 1.

7. The method according to claim 1 , wherein n is 0.

8. The method according to claim 1 , wherein the biocompatible self-removable linker L is of Formula (L):

wherein R 4 is selected from H, optionally substituted C 1 -C 30 alkyl, optionally substituted C 2 -C 30 alkenyl, optionally substituted C 2 -C 30 alkynyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted aryl alkyl and optionally substituted aryl alkyl, X is absent or selected from O and S and X 1 is selected from the following groups:

and wherein m is an integer selected from 0 or 1 and p is an integer selected from 0 or 1, X 2 is selected from O, S, NH, R 12 is selected from H, optionally substituted C 1 -C 30 alkyl, optionally substituted C 2 -C 30 alkenyl, optionally substituted C 2 -C 30 alkynyl, optionally substituted alkoxy, optionally substituted aryl and optionally substituted alkyl-aryl and A is an optionally substituted aromatic ring.

9. The method according to claim 1 , wherein B is a biocompatible non-peptidic moiety cleavable by phosphatases or glycosidases.

10. The method according to claim 1 , wherein B is a phosphate group or at least one glucuronic acid group.

11. The method according to claim 1 , wherein B is a group selected from the following groups:

wherein Z is selected from O and NH and E is selected from —OR 3 and a group D2:

wherein R 2 and R 3 are independently selected from H, optionally substituted C 1 -C 30 alkyl, optionally substituted C 2 -C 30 alkenyl, optionally substituted C2-C30 alkynyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted C 3 -C 8 -cycloalkyl, optionally substituted heterocycloalkyl and a lipidic group; R1D is selected from H, optionally substituted C 1 -C 30 alkyl, optionally substituted C 2 -C 30 alkenyl, optionally substituted C 2 -C 30 alkynyl, optionally substituted alkoxy, optionally substituted aryl and optionally substituted aryl C 1 -C 6 alkyl and q is an integer selected from 0 and 1 and LD is a biocompatible self-removable linker, R is selected from —COOR 9 and CH 2 OH, R 8 , R 10 and R 11 are independently selected from H, or an appropriate protective group for hydroxyl groups and R 9 is selected from H, optionally substituted C 1 -C 30 alkyl, optionally substituted C 2 -C 30 alkenyl, optionally substituted C 2 -C 30 alkynyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted C 3 -C 8 -cycloalkyl and optionally substituted heterocycloalkyl.

12. The method according to claim 1 , wherein B is a group B1.

13. The method according to claim 1 , wherein R 3 is H.

14. The method according to claim 1 , wherein R 2 is an optionally substituted phenyl or a lipid group.

15. The method according to claim 11 , wherein R 2 is a squalene.

16. The method according to claim 1 , wherein B is a group B2.

17. The method according to claim 1 , wherein the compound is selected from the following group:

wherein:
B is a biocompatible non-peptide moiety;
R 1 is selected from H, optionally substituted C 1 -C 30 alkyl, optionally substituted C 2 -C 30 alkenyl, optionally substituted C 2 -C 30 alkynyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heteroaryl and optionally substituted aryl C 1 -C 6 alkyl;
