Abstract:
The present disclosure provides new salts of 5-aminolevulinic acid (5-ALA) and new salts of 5-ALA esters, their preparation, formulation and use as photosensitizing agents in photodynamic therapy, diagnosis and cosmetic cares.

Claim (Index 1):
A salt having formula (I):\n H 2 NCH 2 COCH 2 CH 2 COOR\u00b7X\u2014COOH\u2003\u2003(I) wherein R is selected from the group consisting of hydrogen, unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted carbocyclic, unsubstituted or substituted C 6-12  aryl, unsubstituted or substituted 3-12 membered heterocyclic, and unsubstituted or substituted 5-12 membered heteroaryl; and X is selected from hydrogen, \u2014CY 1 R 1 R 2 , \u2014CY 1 Y 2 R 1 , and \u2014CY 1 Y 2 Y 3 ; wherein Y 1 , Y 2 , and Y 3  are independently selected from Cl, Br, and I; and wherein R 1  and R 2  are independently selected from the group consisting of hydrogen, unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted carbocyclic, unsubstituted or substituted C 6-12  aryl, unsubstituted or substituted 3-12 membered heterocyclic, and unsubstituted or substituted 5-12 membered heteroaryl; or R 1  and R 2  may combine with an atom or atoms to which it is attached to form unsubstituted or substituted C 3-12  cycloalkyl, unsubstituted or substituted 3- to 12-membered heterocyclic, unsubstituted or substituted C 6-12  aryl, or unsubstituted or substituted 5- to 12-membered heteroaryl.
