title: QSAR study on phosphoramidothioate (Ace) toxicities in housefly.
abstract: The present paper describes quantitative structure-activity relationships (QSARs) formulated for a series of phosphoramidothioate (Ace II) analogs. The k(e) values for Ace II-induced inhibition of fly-acetylcholinesterase as well as LD50 for housefly exposed to Ace II analogs were governed by distance-based topological as well as information theoretic indices. In addition, we have also modeled lipophilicity of the phosphoramidothioates used. Excellent results are obtained in each case. The predictive ability of the models were discussed on the basis of cross-validated parameters.
