According to active groups synergetic catalysis principle, a novel phosphodiester receptor 1-(N-guanidinoethyl)-4-(N-hydroxyethyl)-piperazidine hydrochloride was firstly synthesized and the preliminary studies of its DNA cleavage activity. It is characterized and confirmed by methods as 1H NMR and 13C NMR. A couple hardness with softness piperazidine is designed to connect guanidinium group and hydroxyl group; The reserch was showed that the best cleaving conditions was 7.2 in pH; Cleaving DNA by the compound reaction was oxidation process that were proved through the free radicals quenches experiments; The compound can cleaved the pUC 19 DNA by phospholipid transferance was proved by BDNPP. A novel DNA cleavage activity of artificial small organic molecule receptor 1-(N-guanidinoethyl)-4-(N- hydroxyethyl)piperazine hydrochloride containing the electrophilic activation guanidinoethyl and the nucleophilic hydroxyl group side arms was synthesized. The results of pH-dependence indicate pH 7.2 is the optimal pH for DNA cleavage in the presence of 3. Transphosphorylation pathway is the mechanism for the DNA cleavage was proved by BDNPP which is used as the DNA mimics successfully. Copyright

A series of substituted benzothiopyrans was synthesized and examined for antimalarial activity. Some were found to be active and curative at dose levels of 160 - 360 mg/kg against Plasmodium berghei in mice. A few observations concerning structure-activity relationships were made. The benzothiopyrans were prepared by treatment of either the gem-dichloro- or the thionothioflavone intermediate with various primary amines. The thionothioflavone intermediates were made from thioflavones. Condensation of thiophenols with benzoyl acetates gave the thioflavones.
