title: Synthesis and antimicrobial activity of azasteroid-type compounds and related systems. Effect of hydrophilic and lipophilic groups on activity.
abstract: Pyrazole-, pyrazolone- and isoxazole-containing systems were prepared from 3,4-dihydro-6-(hexyloxy)-1(2H)-naphthalenone, 3,4-dihydro-6-(hexadecyloxy)-1(2H)-naphthalenone,3,4-dihydro-6(2-dimethylaminoethyloxy)-1-(2H)-naphthalenone, 3,4-dihydro-7-hexyloxy-1(2H)-phenanthrone, and 3,4-dihydro-7-(2-dimethylaminoethyloxy)-1(2H)-phenanthrone. A number of compounds derived from 7, 8-dihydro-5(6H)-quinolinone were also synthesized and characterized. Both hydrophilic and lipophilic groups were incorporated into certain systems as well as cidal groups. The compounds were screened for their in vitro inhibitory activity against Bacillus subtilis and Pseudomonas fluorescens. Structure-acitivity relationships among the molecular systems are discussed.
