Organotin compounds: industrial applications and biological investigation.
According to Ross (1), there are three main areas in which organotin compounds have product and process utility: (1) heat stabilizers; (2) catalytic agents; (3) biocidal compounds. Organotin derivatives account for the fourth largest production of organometallics amounting to about 3-4 million pounds per year as compared with about 485 million pounds per year for organolead compounds. Originall...
متن کاملPreparation of new 7-hydroxyguanine derivatives and their biological activities.
We prepared new 7-hydroxyguanine derivatives, 7-hydroxyguanosine 5'-monophosphate and N2-tetrahydropyranyl-7-hydroxyguanine, and compared biological activities of 7-hydroxyguanine derivatives including nucleosides acquired previously. 7-Hydroxyguanine and its nucleotide inhibited the focus formation of Rous sarcoma virus. Antitumor activities of these derivatives against mouse leukemia L1210 we...
متن کاملOrganotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...
متن کاملOrganotin compounds and their use for insect and mite control.
A brief overview of biological activity of organotin compounds is given, with emphasis on activity against plant-feeding arthropods. Plictran miticide, containing cyhexatin (tricyclohexylhydroxystannane), the first product to be fully commercialized for control of plant-feeding mites on a broad range of agricultural crops, is used as a model to indicate the chemistry and potential performance, ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
