两种多羟基富勒烯,它们在体外降低有机磷(OP)诱导的乙酰胆碱酯酶(AChE)抑制,通过腹膜内(ip)途径给药或以0.9-24 mg/kg的剂量局部施用,以保护成年雄性小鼠免受指示OP毒性的酶抑制和行为作用,所述OP毒性是由于暴露于1.7 - 2 mg/kg二氟磷酸盐(DFP)ip或2.3 - 2.0 mg/kg二氟磷酸盐(DFP)ip引起的。2.7 mg对氧磷外用。给药模式包括通过ip途径同时给予OP-富勒烯,以及OP后20分钟局部给予多羟基富勒烯。OP螯合的聚羟基富勒烯的好处被指出,并依赖于OP化合物以及聚羟基富勒烯处理的时间和路线。
Two polyhydroxyfullerenes, which decrease organophosphate (OP)-induced acetylcholinesterase (AChE) inhibition in vitro, were administered by the intraperitoneal (ip) route or applied topically at doses of 0.9–24 mg/kg to protect adult male mice from enzyme-inhibiting and behavioral effects indicative of OP toxicity resulting from exposure to 1.7 – 2 mg/kg diphosphorofluoridate (DFP) ip or 2.3 – 2.7 mg paraoxon topical. Dosing paradigms included OP-fullerene simultaneous administration by the ip route, and 20 min post-OP polyhydroxyfullerene treatment topically. Benefits of OP sequestration by the polyhydroxyfullerene were noted and were dependent on the OP compound as well as timing and route of the polyhydroxyfullerene treatment.
