三烃基锡化合物的生物活性主要取决于硅原子上的三个烃基,而且具有极高的生物选择性。混合的三烃基锡化合物是指锡原子上的三个烃基不同的化合物,往往具有多重生物活性。我们曾报道混合的环已基/丁基三烃基锡羧酸酯同时具有杀螨和杀菌活性,并由此开发出一个新型杀螨杀菌剂——双灭锡。含硅的有机锡化合物往往可以降低毒性,并延长药效,硅托尔克 The biological activity of trihydrocarbyl tin compounds depends mainly on the three hydrocarbon groups on the silicon atom and has a very high degree of bio-selectivity. Mixed trialkyltin compounds refer to three different hydrocarbon groups on a tin atom, often having multiple biological activities. We have reported that the mixed cyclohexyl / butyltrihydrocarbyl tin carboxylate has both acaricidal and bactericidal activities and that a new acaricidally effective bactericidal agent - dipivoxil has been developed. Silicone-containing organotin compounds can often reduce toxicity and extend the efficacy of Si-Tolk
