Near-infrared fluorescent pH-sensitive probes via unexpected barbituric acid mediated synthesis.
نویسندگان
چکیده
Novel near-infrared pyrimidine-fused pH fluorescent probes were prepared by an unusual barbiturate-mediated debenzoindolation and subsequent heteroannulation. A plausible mechanistic pathway is proposed, and the final structures were further elucidated by 2D-NMR. All new compounds are highly fluorescent in the near-infrared region and possess excellent spectral sensitivities to environmental pH changes.

Nitric oxide (NO) is a fundamental signaling molecule that regulates virtually every critical cellular function, and it is also a potent mediator of cellular damage in a wide range of conditions mainly via its secondary metabolite peroxynitrite (ONOO ). In this work, we present an o-phenylenediamine (OPD)-locked Sirhodamine deoxylactam, i.e. deOxy-DALSiR, as a near-infrared fluorescent probe fo...

متن کاملNear infrared fluorescence quenching properties of copper (II) ions for potential applications in biological imaging
Fluorescence quenching properties of copper(II) ions have been used for designing Cu(II) sensitive fluorescent molecular probes. In this paper, we demonstrate that static quenching plays a key role in free Cu(II)-mediated fluorescence quenching of a near infrared (NIR) fluorescent dye cypate. The Stern-Volmer quenching constant was calculated to be KSV = 970,000 M in 25 mM MES buffer, pH 6.5 at...
متن کاملStrategies for Developing pH Sensitive Fluorescent Probes
Many physiological processes function efficiently within a well-controlled pH range. Higher acidity level has been implicated with a number of systemic pathologies. The potential of pH sensitive fluorescent probes for reporting on biological environments has been widely utilized in a variety of cell studies and has been recently recognized as a powerful technique for in vivo imaging of diseases...
