Fig. 1: Structures and in vitro activities of compound BZ1 and BZ1-I.

A Structure of compound “N-(4-Ethoxyphenyl)-2,3-dihydro-1H-cyclopenta[b]quinolin-9-amine” referred as BZ1. B In vitro activity of the compound BZ1 against L. donovani DD8 intracellular amastigote promastigotes. C Structure of compound “N-(4-phenoxyphenyl)-1H,2H,3H-cyclopenta[b]quinolin-9-amine” referred to as BZ1-I. D In vitro activity of the compound BZ1-I against L. donovani DD8 intracellular amastigotes and promastigotes. The data points are means and error bars represent standard deviations of three replicates of two independent experiments. Individual data points are shown as lighter-shaded markers in the corresponding colour of each group.
