Sh. Cheon et al., SYNTHESIS AND STRUCTURE-ACTIVITY RELATIONSHIP STUDIES OF SUBSTITUTED ISOQUINOLINE ANALOGS AS ANTITUMOR AGENT, Archives of pharmacal research, 21(2), 1998, pp. 193-197
A number of substituted isoquinolin-1-ones, possible bioisosteres of t
he 5-aryl substituted 2,3-dihydroimidazo[2,1 -a]isoquinolines, were sy
nthesized and tested for their antitumor activity against five differe
nt human tumor cell lines. O-(3-hydroxypropyl) substituted compound (1
5) exhibited the best antitumor activity which is 3-5 times better tha
n 5-[4'-(piperidinomethyl) phenyl]-2,3-dihydroimidazo [2,1-a]isoquinol
ine (1).
