  Thioesters for the in vitro evaluation of agents to image brain cholinesterases

  摘要：

  Cholinesterases are associated with pathology characteristic of conditions such as Alzheimer's disease and are therefore, considered targets for neuroimaging. Ester derivatives of N-methylpiperidinol are promising potential imaging agents; however, methodology is lacking for evaluating these compounds in vitro. Here, we report the synthesis and evaluation of a series of N-methylpiperidinyl thioesters, possessing comparable properties to their corresponding esters, which can be directly evaluated for cholinesterase kinetics and histochemical distribution in human brain tissue. N-methylpiperidinyl esters and thioesters were synthesized and they demonstrated comparable cholinesterase kinetics. Furthermore, thioesters were capable, using histochemical method, to visualize cholinesterase activity in human brain tissue. N-methylpiperidinyl thioesters can be rapidly evaluated for cholinesterase kinetics and visualization of enzyme distribution in brain tissue which may facilitate development of cholinesterase imaging agents for application to conditions such as Alzheimer's disease.

  Compounds useful for the early diagnosis of malignant tumors, multiple sclerosis, and especially Alzheimer's Disease and related dementias; especially compounds of Formula (I) wherein R 1 is selected from the group consisting of hydrogen, cyano, fluoro, iodo, alkyl, and aryl; R 2 is selected from the group consisting of hydrogen, alkyl, and aryl; X is selected from the group consisting of CH 2 , CH 2 O, oxygen, OCH 2 , CH 2 S, SCH 2 , NH, N-alkyl, and N-aryl; Y is an optional spacer group, absent or selected from the group consisting of oxygen, sulfur, NH, N-alkyl, and N-aryl; and Z is selected from the group consisting of alkyl substituted with cyano, fluoro, or iodo and aryl substituted with cyano, fluoro, or iodo. In a preferred embodiment, R 1 and R 2 are hydrogen, X is CH 2 O, Y is absent, and Z is phenyl substituted with fluoro, cyano, or iodo. In some embodiments, Z is more specifically 18 F-phenyl or 123 I-phenyl or 131 I-phenyl. Other compounds are also provided.
