In-vivo probe for real time longitudinal monitoring of inducible nitric-oxide synthase in living cells and animals
11591476 · 2023-02-28 ·

The present disclosure relates to an in vivo fluorescent or radioactive probe represented by a compound of formula I which is capable of longitudinal imaging of inducible nitric oxide synthase (iNOS) expression in living cells and living animals on a real time basis. The probe of the present disclosure can exhibit specific and high affinity binding to the iNOS enzyme with reduced enzyme inhibitory property and also enables longitudinal monitoring of iNOS expression along with its activity or NO production in a same experimental subject throughout the progression of a physiological or disease process without employing separate subjects as controls and experimental. The present disclosure further provides a rapid and inexpensive real time method for visualizing iNOS expression and its activity in living cells and living animals precisely, conveniently and reversibly along with simultaneous in vivo imaging of its catalytic product, nitric oxide (NO) in live physiological settings.

Amadoriase having enhanced dehydrogenase activity

Provided are an amadoriase that is less likely to be influenced by oxygen concentration and a method and a reagent kit for measurement of HbA1c using such amadoriase. Provided are an amadoriase that is obtained via substitution of one or more amino acid residues at a position or positions corresponding to the position(s) selected from the group consisting of positions 280, 267, 269, 54, and 241 of the amadoriase derived from the genus Coniochaeta, a method for measurement of HbA1c, a reagent kit for measurement, and a sensor using such amadoriase. The modified amadoriase according to the invention has a lowered oxidase activity and an enhanced dehydrogenase activity, and this enables the use of an electron mediator, and this reduces the influence of oxygen concentration. Thus, HbA1c can be measured with high sensitivity.
