Abstract: In the title molecule, C16H13BrOS, the mean planes of the 4-bromophenyl and 4-(methylsulfanyl) phenyl groups are twisted by 47.4 (2)degrees from each other. The angles between the mean plane of the prop-2-en-1-one group and those of the 4- bromophenyl and 4-(methylsulfanyl) phenyl groups are 21.1 (4) and 26.3 (2)degrees, respectively. Crystal packing is characterized by alignment of adjacent molecules syn to each other, oblique to the ac plane and stacked in parallel arrays along the c axis of the unit cell. The closest distance between 4-bromophenyl rings is 4.536 (2) angstrom; that between 4-(methylsulfanyl) phenyl groups is 4.539 (2) angstrom.

TL;DR: The synthesis and characterization of new fluorinated chalcone (FCH) is reported and the small energy difference between the conformers indicates that the conversion between them can takes place at room temperature and the β isomer is stable only in solid state.

TL;DR: A comparison of the coefficient plots for the antileishmanial effect and the lymphocyte-suppressing activity discloses significant differences which should make it possible to design chalcones having a high antileishesmanial activity without suppressing the proliferation of lymphocytes.
