Efficient Utilization of 6-Aminouracil to Synthesize Fused and Related Heterocyclic Compounds and Their Evaluation as Prostate Cytotoxic Agents with Cathepsin B Inhibition

Abstract: 6-aminouracil 1 was utilized to introduce different heterocyclic rings at C-6 position through various synthetic strategies. The synthesized compounds bear rings that are either directly attached to the uracil back bone as in compounds 6, 12a-c and 15, or attached through an amino bridge as compounds 3a-c, 5a, b, 7a, b, 9 and 10, or through an imino bridge as compound 18. Also, compounds 4, 8, 11a-c, 14, 16 and 17 bearing biologically active side chains were synthesized. In addition to, compounds 13, 19, 20, 2… Show more

“…It should be mentioned that other active methylene compounds 10'' can be used instead of dialkyl malonates in order to reach other N-heterocyclic systems following the same domino pathway. [40][41][42] When nitrile functions are present on the active methylenes 10'', the formation of enamino -lactams 19, from the imine intermediate 18, can be observed. An interesting domino reaction on these lines was published by Tverdokhlebov and co-workers with the construction of 2 cycles during the process leading to 22 (Scheme 9).…”

“…Барбітурові і тіобарбітурові кислоти, 6-аміноурацил та 6-аміно-2-тіоурацил розглядаються як привілейовані структури у відкритті лікарських засобів з широким спектром біологічної активності та синтетичної доступності. Противірусна та протипухлинна дії є двома найбільш відомими видами біологічної активності аналогів урацилу, проте вони виявляють також гербіцидну, інсектицидну та бактерицидну активності [11][12][13][14]. Численні модифікації структури урацильного фрагмента ведуть до розробки конденсованих похідних, які демонструють кращі фармакологічні та фармакокінетичні властивості, включаючи підвищену біоактивність, селективність, метаболічну стабільність, абсорбцію і меншу токсичність [15][16][17].…”
