Future medicinal chemistry 2020 MarAim: Design and synthesis of novel morpholinopyrimidine-5-carbonitriles as antitumor agents. Materials & methods: New series of morpholinopyrimidine-5-carbonitriles have been synthesized. 19 derivatives (3b, 4a, 5-6, 9-12, 13a-e, 14a-c and 15-17) were evaluated for their in vitro antitumor activity by the National Cancer Institute (NCI; MD, USA). Moreover, compound 13e was evaluated against PI3K (α, β and δ) and the mechanism of its cytotoxic activity on leukemia SR was studied. Results: Compound 13e possessed remarkable broad spectrum antitumor activity with GI50 (median growth inhibition) and TGI (total growth inhibition) values of 6.15 and 28.66 μM, respectively, caused cell cycle arrest at G2-M phase and significant increase in the percentage of annexin V-FITC - positive apoptotic cells, also increased the level of active caspase-3. Moreover, 13e revealed good safety profile against transformed human liver epithelial-2 (THLE2).
