was not tested because it is a chemotherapy drug with side effects that make it unsuitable as a potential stroke treatment.

([s.sup.6]G) and 6-Mercaptopurine ([s.sup.6]Pu).
Generally, recommended therapies for UC patients include anti-inflammatory drugs (corticosteroids, prednisolone, aminosalicylic acid, and sulfasalazine), immunosuppressants (thiopurines, azathioprine, 6-mercaptopurine, and 6-thioguanine
), and antibiotics (metronidazole and ciprofloxacin) [3-5].
Through their metabolite 6-thioguanine
, the thiopurines azathioprine and 6-mercaptopurine can inhibit RAC-1 and the efficacy of anti-apoptotic factors in lymphocytes .

Two months later, when the transaminases were within the normal range, he received 6-thioguanine
(6-TG) 25 mg a day, that was progressively increased to 80 mg a day.
Bioisosteric replacement of carbonyl oxygen in guanine (pyridine-imidazole ring system), a nitrogenous base by S gives 6-thioguanine

Intraerythrocyte concentrations of 6-thioguanine
nucleotides (6TGNs) were low (132 pmol/8 x 108 erythrocytes; therapeutic interval, 230-400 pmol/8 x [10.sup.8] erythrocytes), and 6-methylmercaptopurine ribonucleotides (6-MMPRs) were very high (11 666 pmol/8 x [10.sup.8] erythrocytes; therapeutic interval, <5800 pmol/8 x [10.sup.8] erythrocytes).
