  Benzylphosphonic acid inhibitors of human prostatic acid phosphatase

  摘要：

  A series of alpha-substituted benzylphosphonic acids is described as inhibitors of human prostatic acid phosphatase, an enzyme which has been used as a model to study aryl phosphatases. The most potent inhibitors in this series are 2-trifluoromethylbenzhydrylphosphonic acid (9 mu M), and alpha-(2-phenylethyl)benzylphosphonic acid (14 mu M) The structure-activity studies suggest that bulk tolerance beyond the phosphate binding area limits the steric or hydrophobic contribution to inhibitor potency achieved through alpha-carbon substitution.

• Can One Predict Changes from S_N1 to S_N2 Mechanisms?

  lifetimes of benzhydrylium ions in the presence of amines and DMSO. The change from S(N)1 to S(N)2 mechanism occurred close to the point where the calculated rate constant for the collapse of the benzhydrylium ions with the amines just reaches the vibrational limit; that is, the concerted S(N)2 mechanism was only followed when it was enforced by the lifetime of the intermediate. The nucleophile-specific

  Y(BnBr) or Y(Br). Correlation analyses against corresponding logk of α-tert-butyl-(2-naphthyl) methyl bromide provided evidence for the importance of different extent of solvation in delocalized transition state and for nucleophilic solvent intervention in the solvolysis of benzhydryl systems.

  单取代的苯甲基溴化物的溶剂化使logk具有σ+常数，而不具有Y（BnBr）或Y（Br）的优异线性相关性。对α-叔丁基-（2-萘基）甲基溴的相应logk进行相关分析，提供了证据表明，在离域过渡态中不同程度的溶剂化非常重要，并且亲核溶剂的干预对苯甲基系统的溶剂化具有重要意义。
