PYRROLO[2,3-C]PYRIDINES AS IMAGING AGENTS FOR NEUROFIBRILARY TANGLES

Page/Page column 114, (2016/01/01)
Pyrrolopyridine compounds of formula (I) or their pharmaceutically acceptable salts are disclosed, which may be suitable for imaging tau aggregates, b-sheet aggregates, beta-amyloid aggregates or alpha- synuclein aggregates, and hence are useful in binding and imaging tau aggregates in Alzheimer's patients. More specifically, the compounds are used as tracers in positron emission tomography (PET) imaging to study tau deposits in brain in vivo to allow diagnosis of Alzheimer's disease and other neurodegenerative diseases characterized by tau pathology. Futher, the compounds are useful for measuring clinical efficacy of therapeutic agents for Alzheimer's disease and other neurodegenerative diseases characterized by tau pathology.

4-Aminobipyridine derivatives form strong inclusion complexes with cucurbit[6]uril, exhibiting remarkably large enhancements in fluorescence intensity and quantum yields. The remarkable complexation-induced pKa shift (ΔpKa =3.3) highlights the strong charge-dipole interaction upon binding. The reversible binding phenomenon can be used for the design of switchable beacons that can be incorporated into cascades of binding networks. This concept is demonstrated herein by three different applications: 1) a switchable fluorescent beacon for chemical sensing of transition metals and other ligands; 2) direct measurement of binding constants between cucurbit[6]uril and various nonfluorescent guest molecules; and 3) quantitative monitoring of biocatalytic reactions and determination of their kinetic parameters. The latter application is illustrated by the hydrolysis of an amide catalyzed by penicillin G acylase and by the elimination reaction of a b-cabamoyloxy ketone catalyzed by aldolase antibody 38C2.
