بررسی بیولوژیک مشتقاتی از خانواده آمینوپیریمیدون ها به عنوان مهارکننده رشد و القاء آپوپتوز بر روی رده سلولیK562 لوسمی میلوئید مزمن انسان

Background and purpose: Chronic myeloid leukemia (CML) is the most widely recognized form of leukemia. Nowadays, trying to find new synthetic compounds is one of the basic strategies to find new drugs to treat CML. In present study the effects of some of Pyrimidone derivatives on proliferation, viability, and apoptosis of human leukemia K562 cell line as experimental model for CML have been investigated. Material and Methods: K562 cells were treated by various concentrations of 4 amino pyrimidone derivatives. Anti- proliferative effects of the compounds were studied using trypan blue exclusion test. Apoptosis was detected by fluorescent microscope and DNA fragmentation assay. Results: Our study showed that: 1) aminopyrimidone derivatives induced growth inhibition in K562 cells in concentration- and time-dependent manner, 2) The aminopyrimidone derivatives inhibited viability and induced apoptosis in these cells. 3) The apoptotic and growth inhibitory effects of these compounds were dependent on their molecular structure. Conclusion: According to growth inhibitory and apoptotic effects of new synthetic, aminopyrimidone derivatives could be proposed as new and effective compounds for more investigations in treatment of leukemia.
