Compound D7 does not inhibit the growth of Salmonella enterica sv. Typhimurium or C. trachomatis serovar D in HeLa cells. A: compounds D4, D5, D6 and D7 (10 μM) or DMSO (0.1%), did not prevent replication of Salmonella enterica sv. Typhimurium SL1344 in HeLa cells. Compounds were added to the media 2 hours after host cell infection, and bacteria harvested at both 2 and 16 hpi in order to plot the fold change in colony forming units. B: compound D7 did not inhibit the growth of Chlamydia trachomatis serovar D. Compound D7 (10 μM) was added to cell monolayers 1 hpi and inclusions were stained at 48 hpi. Large inclusions were seen in both D7- (bottom right panel) and DMSO-exposed (0.1%; top right panel) cells while small inclusions were seen for C. pneumoniae in D7-exposed cells. Arrows indicate representative inclusions. The monoclonal antibody contained Evan's Blue counterstain for detection of host cells.
