The synthesis and preliminary biological testing for in vitro cholesterol biosynthesis inhibitory activity of 2-indeneacetic acid, 2-methyl-1,2-dihydro-2-naphthoic acid, and their 5- and 7-chloro derivatives, respectively are described. These compounds were prepared as trans- and cis-analogs of the known antilipemic agent 3-methyl-4-phenyl-3-butenoic acid. Although both series of compounds showed cholesterol biosynthesis inhibitory properties, chloro substitution enhanced potency only in the cis-system. These findings are discussed in terms of a possible relationship between the cis-compounds and clofibrate-type antilipemic agents.
