Near-membrane iminocoumarin-based low affinity fluorescent Ca(2+) indicators.
Two new potential near-membrane iminocoumarin-based fluorescent Ca(2+) indicators were synthesized and the spectral profiles of their free and Ca(2+) bound forms were studied. The probes incorporate in their BAPTA-related structures, the 3-(benzimidazolyl)iminocoumarin or the 3-(benzothiazolyl)iminocoumarin moiety, substituted at the imino nitrogen with an n-dodecyl lipophilic chain. The compou...
متن کاملMetal ion-based RNA cleavage as a structural probe.
It is well established that many metal ions accelerate the spontaneous degradation of RNA. This property has been exploited in several ways to garner information about RNA structure, especially in regards to the location of site-specifically bound metal ions, the presence of defined structural motifs, and the occurrence of conformational changes in structured RNAs. In this chapter, we review th...
متن کاملA New Colorimetric Azo-azomethine Probe for Fluoride Ion Detection Based on the Proton Transfer Signaling Mode: Real-life Applications
Four novel receptors were designed and synthesized for colorimetric detection of F− ions. The introduction of four electron withdrawing groups into the backbone of the receptors makes the two phenolic groups efficient hydrogen bonding sites. The binding properties of receptors with anions were examined for the first time by UV–Vis, 1H NMR and fluorescence spectroscopies. The addition of F− resu...
متن کاملHydrogen sulfide mediated cascade reaction forming an iminocoumarin: applications in fluorescent probe development and live-cell imaging.
The study on a fluorescent probe that undergoes a H2S mediated cascade reaction to form an iminocoumarin fluorophore is reported. The probe features better water solubility and fast sensing time (t1/2 = 6.1 min and response time = 24 min) as key advances compared to the reported probe that works on a similar mechanism. The sensing mechanism of the probe was demonstrated by mass spectrometric, H...
متن کاملThe Dilepton Probe in Heavy-Ion Collisions
Dileptons provide direct observables of the electromagnetic currentcurrent correlator in the hot and/or dense medium formed in heavy-ion collisions. In this article an overview is given about the status of the theoretical understanding of the dilepton phenomenology in heavy-ion collisions from studies of the in-medium properties of hadrons and partons within many-body theory and about connectio...
