It is demonstrated during the reduction of ledakrin that a key metabolite, a compound with anadditional five-membered ring attaching to positions 1 and 9 of the acridine core and with the retained 9-aminoalkyl side chain, is formed in all the systems that are studied. It is determined that the reactive nitrogen atoms of this additional ring undergo further transformations resulting in the formation of a six-membered ring produced by the addition of a carbon atom to the dihydropyrazoloacridine ring. Furthermore, it is observed that positions 2 and 4 of ledakrin’s acridine ring are susceptible to nucleophilic substitution as revealing by the studies with dithiothreitol. Additionally, although most products from the reduction of ledakrin are extremely unstable, 1-aminoacridinone, producing enzymatically and with dithiothreitol, exhibiting persistent stability under the studied conditions[1].

Six-week-old male rats are injected with 3-methylcholanthrene (4 mg/animal) for 3 days before decapitation. Livers are removed, homogenized in a homogenizer, and centrifuged for 30 min at 10000g.The activation of ledakrin with the microsomal fraction of rat liver is carried out in 0.16 M Trizma base buffer (pH 7.4). The incubation mixture consists of 125 mM nicotinamide, 100 mM glucose 6-phosphate, 10 mM NADPH, glucose-6-phosphate dehydrogenase (40 units), rat liver microsomes (5 mg/mL), andledakrin (1 mmol)[1].
