Herbicidal Activities of Phosphoramidothionates
Journal of Weed Science and Technology, 1973 Phosphoramidothionate を多数合成し, 検討したところ, 除草剤として O-ethyl-O-(2-nitro-p-tolyl)N-isopropyl phosphoramidothionate (amiprophos) が優れた活性を有したので, 本剤の作用性について検討し, 若干の知見をえた。(1) O-alkyl-O-aryl phosphoramidothionate に高い除草活性を有する化合物が見出された。(2) 化学構造的に種々検討したところ, アミノ基は mono-alkylamino が有効であった。アルキルは炭素数3以上で有効で, 特にイソプロピルが優れていた。(3) O-アルキルはあまり活性に影響を与えないが, 低級アルキルが有効であり ...

In vitro anticryptosporidial activity of dinitroaniline herbicides [PDF]
FEMS Microbiology Letters, 1996 Despite the evaluation of over 100 antimicrobial drugs, the diarrheal disease cryptosporidiosis has remained refractory to treatment. We report the evaluation of five dinitroaniline herbicides including trifluralin, profluralin, nitralin, pendimethalin, and fluchloralin for anticryptosporidial activity in an in vitro cultivation model of ...
