“…Less frequently were the following PS naphthalene derivatives (Azidonaphthalene (AzNAP); 1,5-diazidonaphthalene (DAN); 1,5-Diiodonaphthalene (DINAP), 7.6% (n = 3/39) [ 37 ], oxazolidine (JL103, JL118, JL122), 7.6% (n = 3/39) [ 33 ] and to Amotosalen derivatives (Amotosalen-HCl and Amotosalen) 5% (n = 2/39) [ 52 , 53 ] respectively. The following PS were not grouped, and individually correspond to 2.6% (n = 1/39), such as 5-aminolevulinic acid (ALA) [ 36 ], Solid phase fullerene-based PS (SPFPS) [ 38 ], Ortoquin [ 32 ], Indocyanine green (ICG) [ 50 ], rhodanine derivative (LJ001) [ 33 ], Fotoditazine [ 60 ], Hypericin (Hy) [ 58 ], Diazidobiphenyl derivative (DABIPH) [ 37 ] and benzochlorine derivative (Zn-BC-AM) [ 43 ], Methylene blue (MB) [ 41 , 49 ] and curcumin (CUR) [ 51 , 57 ]. Highlight MB and CUR which were the most frequent PS in analyzed articles.…”
