Design, synthesis and evaluation of novel P450 fluorescent probes bearing α-cyanoether
摘要:
Four chi-cyano-containing ethers based on 2-alkoxy-2-naphtyhlacetonitriles have been designed as a novel Structural class of cytochrome P450 fluorescent probes. Their syntheses, fluorescence properties and evaluation in the fluorogenic assay of cytochrome P450 monooxygenase are reported. After P450 enzymatic O-dealkylation, the cyanohydrin metabolite of the four new substrates rearranges to a fluorescent aromatic aldehyde with a larger Stokes shift. and tile new substrates exhibit higher specific activities than that of the commercial substrate 7-ethoxyresorufin (ER).

Ethers and esters of cyanohydrins that contain optically detectable moieties are highly effective for detecting, monitoring, and measuring the activity of enzymes that cause the cleavage of certain types of substrates. The cyanohydrins function as proaldehydes and proketones, spontaneously converting to aldehydes and ketones, respectively, which provide a large increase in optical detectability relative to both the starting esters and ethers and the cyanohydrins.
