Antischistosomal action of thioxo-imidazolidine compounds: An ultrastructural and cytotoxicity study

► LPSF/PT-5 and LPSF/PT-11 are new imidazolidine compounds. ► These compounds induced tegument damage in S. mansoni in vitro. ► LPSF/PT-5 and LPSF/PT-11 showed similar behavior than Praziquantel. ► These imidazolidines can be used as anti-Schistosome compound on in vitro assays.
