“…a ·CH 2 OH radical, which is probably responsible for the formation of ATAM. 4 As solvent free radicals are obviously the main players in the formation of new compounds the idea arises that these radicals can be formed either by γ-irradiation or by radical forming agents such as Fenton's reagent. To verify this assumption we ascertained if Fenton's reagent is applicable to "re-combinatorial chemistry".…”

Re-combinatorial chemistry, an auspicious method for generating small-compound libraries by means of γ-irradiation of active lead compounds, disclosed the formation of new compounds with reassembled or rearranged structures mainly to be derived from radical chemistry. Therefore, Fenton's reagent was applied to a methanol/water solution of tacrine to mimic the irradiation. In fact, these preliminary studies revealed the generation of a small compound library with a product composition similar to those obtained by γ-irradiation.

“…The radiolysis of CH 3 OH and CH 3 OH/H 2 O mixtures with ionizing radiation has been reported elsewhere in the literature [20][21][22]. These studies have shown that pulse radiolysis can be used as a convenient source of e À solv and C Å H 2 OH radicals according to Eq.…”

“…Thiocyanate dosimetry was carried out at the beginning of each experimental session. The details of the dosimetry have been reported elsewhere [35] [39]. The procedure is based on the concentration of (SCN) À 2 radicals generated by the electron pulse in an N 2 Osat.…”

[16 -18], and can be even studied as biological models for metalloproteins [19]. Moreover, the structural features of the macrocycles and the unique radiophysical properties of copper radioisotopes led to their potential usefulness in diagnostic and/or therapeutic applications [20].Copper ions in different oxidation states are present in a diverse group of metalloenzymes, in which the metal is coordinated to N-, O-, and S-atoms. In type-I Cucenters (e.g., in amicyanin, plastocyanin, and pseudoazurin), the Cu II ion is coordinated in a trigonal-planar fashion by 2 histidine and 1 cysteine ligand (N 2 S coordination) with one or two weakly interacting axial ligands (S or O), whereas type-II Cu-centers (e.g., in dioxygenase, monooxygenases, nitrite reductase) exhibit a square-planar coordina-
