Preclinical and Healthy Volunteer Studies of Potential Drug–Drug Interactions Between Tenapanor and Phosphate Binders

Published: September 2016

AbstractTenapanor (RDX5791, AZD1722), a first‐in‐class small molecule with minimal systemic availability, is an inhibitor of the sodium/hydrogen exchanger isoform 3. Tenapanor acts locally in the gut, where it reduces absorption of sodium and phosphate. It is being studied in patients with chronic kidney disease requiring dialysis, who are often administered phosphate binders such as sevelamer to help control hyperphosphatemia. We investigated whether coadministration of tenapanor with phosphate binders (sevelamer or calcium‐based binders) impacts the pharmacodynamic effects of tenapanor. In vitro studies suggested a binding interaction between tenapanor and sevelamer, but this did not translate into altered pharmacodynamic effects in rats. An open‐label, 2‐way crossover study was then conducted in healthy volunteers (NCT02346890). This showed that 4 days’ treatment with tenapanor hydrochloride (15 mg twice daily) with or without sevelamer carbonate (800 mg 3 times daily) resulted in comparable 24‐hour stool and urinary sodium and phosphorus levels. Stool frequency, consistency, and weight were also comparable between the treatments. These results suggest that the binding between sevelamer and tenapanor observed in vitro does not translate into altered pharmacodynamic effects in humans.
Zinc(II) Ion Sensing in Aqueous Micellar Solution Using Modified Bipyridine‐Based “Turn‐On” Fluorescent Probes and its Application in Bioimaging
Authors: Pawar Shweta , Akula Mahesh , Labala Suman , Venuganti Venkata Vamsi Krishna , Bhattacharya Anupam , Nag Amit 
Published: September 2016

AbstractThe bipyridine‐based constructs 4‐(pyridine‐2‐yl)‐3H‐pyrrolo[2,3‐c]quinoline (PPQ) and [6‐(3H‐pyrrolo[2,3‐c]quinolin‐4‐yl)pyridin‐2‐yl]methanol (PPQ‐OH) and their assemblies with surfactants are evaluated as turn‐on fluorescent sensors for Zn2+ ions in aqueous solution. This study strives to overcome the problem of low water solubility of the hydrophobic PPQ and PPQ‐OH by using micelles. Whereas the ligands show selective sensing behavior for Zn2+ over important biological cations including Na+, K+, Ca2+, Mg2+ in anionic sodium dodecyl sulfate and non‐ionic Tween 80 micelles, no Zn2+ sensing is observed in cationic cetyltrimethylammonium bromide micelles. Unlike in DMF, Cd2+ interference is observed in aqueous conditions, which can be avoided either by performing the study at pH≥9 or by carrying out a time‐resolved fluorescence study. Analysis of the Job plot data, the fluorescence lifetimes, and experiments on varying micellar shape and pH, confirms that the coordination volume of the resulting octahedral metal complex and formation of a five‐membered chelate ring are critical factors for Cd2+ interference. The described sensing systems are capable of detecting Zn2+ ions at the micromolar level. Additionally, it is shown that PPQ and PPQ‐OH can be used to detect Zn2+ in HeLa cells under physiological conditions in bioimaging studies.
Optimal cooperative beamforming design in cognitive radio networks with multiple secondary user links
Authors: Zeraatkar Moghaddam Javad , Farrokhi Hamid , Neda Naaser 
Published: September 2016

SummaryIn this paper, a novel beamforming method is proposed for a more realistic cognitive radio system with several secondary transmitters and receivers, a number of relays, and 1 primary transmitter and receiver. When the primary user link is idle, all secondary transmitters access temporal spectrum holes to simultaneously broadcast their information to the relays each associated with an infinite buffer. In the next stage, the relays transmit the information to the secondary receivers using a cooperative beamforming method no matter whether primary user link is silent or not. The proposed method of designing the beamforming vector enables the system to maximize the power received by the secondary users while maintaining the interference plus noise power at the primary user receiver below a predefined threshold. Results of simulations confirm validity of the method and improved performance compared to the zero‐forcing beamforming. The impact of channel quality between nodes on the performance of the system is also investigated.
