7-benzyl-4-(2-methylbenzyl)-2,4,6,7,8,9-hexahydroimidazo[1,2-a]pyrido[3,4-e]pyrimidin-5(1H)-one, salts thereof and methods of using the same in combination therapy
View Patent ↗This disclosure relates, at least in part, to a method of treatment. In one embodiment, the method of treatment comprises administering to a subject in need of such treatment a first therapeutic agent including compound (1): or a pharmaceutically acceptable salt thereof in combination with a second therapeutic agent, wherein the first therapeutic agent and the second therapeutic agent are administered either simultaneously or sequentially.
1. A compound having a formula (10)
or a salt thereof; wherein, R 1 and R 2 independently represent hydrogen, alkyl, cycloalkyl, cycloalkylalkyl, carboxyl, haloalkyl, alkenyl, cycloalkenyl, alkynyl, aryl, aralkyl, hydroxyalkyl, alkoxy, aryloxy, alkoxyalkyl, alkoxycarbonyl, aralkoxy, aralkylthio, alkanoyl, mercapto, alkylthio, arylthio, alkylsulfinyl, arylsulfinyl, alkylsulfonyl, arylsulfonyl, heteroaryl, acyl, and heterocycle radicals, and wherein when R 1 represents CH 2 Ph, R 2 does not represent CH 2 -((2-CH 3 )-Ph.
2. The compound according to claim 1 , wherein R 1 is CH 2 Ph and R 2 is CH 2 -((2-Cl)-Ph).
3. The compound according to claim 1 , wherein R 1 is CH 2 Ph and R 2 is CH 2 -(2-thienyl).
4. The compound according to claim 1 , wherein R 1 is CH 2 Ph and R 2 is CH 2 CH 2 Ph.
5. The compound according to claim 1 , wherein R 1 is CH 2 Ph and R 2 is CH 2 CH 2 (4-N-benzyl-piperazine).
6. The compound according to claim 1 , wherein R 1 is CH 2 Ph and R 2 is CH 2 -(2,4-di F-Ph).
7. The compound according to claim 1 , wherein R 1 is H and R 2 is CH 2 -((2-CH 3 )-Ph.
8. The compound according to claim 1 , wherein R 1 is CH 3 and R 2 is CH 2 -((2-CH 3 )-Ph.
9. The compound according to claim 1 , wherein R 1 is CH 2 CH 2 Ph and R 2 is CH 2 -((2-CH 3 )-Ph.
