Title:
PHOTOSENSITIZING DYE
Document Type and Number:
WIPO Patent Application WO/2021/261546
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a compound which has absorption in the near-infrared region and achieves a high efficiency of singlet oxygen generation (quantum yield), while exhibiting high tumor toxicity in combination with immunotoxin. The present invention provides a compound represented by formula (1) or a salt thereof. (In the formula, each of L1 and L2 independently represents a single bond, -O-, -CO-, an alkylene group having from 1 to 8 carbon atoms, a sugar chain or a combination thereof; each of R1 and R2 independently represents an alkyl group having from 1 to 8 carbon atoms, a carboxylic acid group, an amino group, a hydroxyl group, a thiol group or a biotin residue; each of R3, R4, R5, R6, R7 and R8 independently represents an alkyl group having from 1 to 8 carbon atoms, a phenyl group, a carboxylic acid group, an amino group, a hydroxyl group, a thiol group or a biotin residue; and M represents Mg, Zn, Fe, P, Si, Cu, Sn, Al, Ti, Mo or Ni.)
