A method for determining one or more parameters of a beverage comprising one or more reducing agents. The method comprising the step of introducing a spin probe to a sample of the beverage, the spin probe capable of reacting with the one or more reducing agents. A plurality of electron paramagnetic resonance (EPR) spectra of the sample over a time period as the spin probe reacts with the one or more reducing agents is obtained. The plurality of obtained EPR spectra of the sample is used to determine one or more parameters of the sample.
Flexibility of small molecular CD4 mimics as HIV entry inhibitors
structural features, an aromatic ring, an oxalamide linker and a piperidine moiety. We have shown previously that introduction of a cyclohexyl group and a guanidine group into the piperidine moiety and a fluorine atom at the meta-position of the aromatic ring leads to a significant increase in the anti-HIV activity. In the current study, the effects of conformational flexibility were investigated by
