| Summary: | A simple synthesis and study by UV-vis, IR, NMR, ESI-CID-MS2 and X-ray diffraction of ((2E)-2-(1-{4-[(7-chloroquinolin-4-yl)amino]phenyl}ethylidene)hydrazinecarbothioamide is reported. It was tested in vitro against chloroquine-resistant strain (W2) of Plasmodium falciparum, hemozoin (β-hematin) formation and cysteine protease falcipain-2. In general, it was found to possess a proved activity in its inhibitory power on the parasite but less active on the formation of hemozoin (β-hematin) and falcipain-2. Also, the X-ray analysis presented an unexpected electronic density that can be assigned like S(2). This electronic density can be attributed to autocondensation of thiosemicarbazide, generating H2S as a subproduct.
