Data computed from Wong et al., 2000 and Kovarik et al., 2004. Structures of SP-cycloheptyl, 3,3-dimethylbutyl and isopropyl methylphosphonate conjugates with AChE are shown.

kr (wild type) was 122, 102 and 1330 min−1M−1 for SP-cycloheptyl, 3,3-dimethylbutyl and isopropyl methylphosphonate conjugates, respectively (Kovarik et al., 2004).

3

kr (wild type) was 0.66, 0.18 and 1080 min−1M−1 for SP-cycloheptyl, 3,3-dimethylbutyl and isopropyl methylphosphonate conjugates, respectively (Kovarik et al., 2004).
