    Development of chiral praziquantel analogues as potential drug candidates with activity to juvenile Schistosoma japonicum
    摘要:
    A series of chiral praziquantel analogues were synthesized and evaluated against Schistosoma japonicum both in vitro and in vivo. All compounds exhibited low to considerable good activity in vivo. Remarkably, worm reduction rate of R-3 was 60.0% at a single oral dose of 200mg/kg against juvenile stage of Schistosoma japonicum. The target compounds displayed in vivo antischistosomal activity against both Schistosoma japonicum and Schistosoma mansoni. Furthermore, all R-isomers displayed stronger antischistosomal activity than S-isomers in vivo, indicating R-isomers were the active enantiomers, while S-isomers were less active ones. This structure activity relationship (SAR) could have important implications in further drug development for schistosomiasis.

    The title compound is the main metabolite of the anthelmintic agent praziquantel. The synthesis or cis‐ and trans‐4‐OH derivatives (as well as their enantiomers) of praziquantel is described. Thus, racemic, (+)‐ and (‐)‐pyrazinoisoquinolin‐4‐one (1) was reacted either with 4‐oxocyclohexane carboxylic acid chloride or with 4‐oxocyclohexane carboxylic acid in the presence of DCC to give the racemic,
