—— | 6-butyl-5,6-dihydrobenzimidazo[2,1-a]isoquinoline-5-carboxylic acid | 436801-38-6 | C20H20N2O2 | 320.391 |
6-Butyl-5,6-dihydrobenzimidazo[2,1-a]isoquinoline, 3,9- and 3,10-dimethoxy, and 3,9- and 3,10-dihydroxy analogues, and their 12-methyl quaternary salts were prepared by a multistep route. Cytotoxicities against 55 human cancer cell lines were measured in the National Cancer Institute screen. The quaternary salts of the dimethoxy compounds (15b/c) were clearly the most active overall, with a mean graph midpoint (MGM) value of 2 m.
