Abstract: EGCG-Zn2+ molecular complexes exhibit a significantly higher affinity than the EGCG molecule alone or Zn2+ alone for binding to different SARS-CoV-2 molecular targets and show virtually complete antiviral suppressive activity (>99%) against this virus in experimental models of infection. EGCG-Zn2+ complexes have a lower toxicity than EGCG alone in transfected human cells. The combination of EGCG and Zn2+, significantly improved some key pharmacokinetic parameters of EGCG in humans. Thus, these complexes can be used as a new broad-spectrum method for chemoprophylaxis or treatment of viral diseases by using formulations containing a composition of EGCG and Zn2+ or EGCG-Zn2+ complexes in sufficient amount to reach a blood concentration with antiviral effect, minimizing safety issues in humans.

Abstract: Bistable devices are constructed using a polynucleotide platform for sensing molecular events such as binding or conformational changes of target molecules. Uses include measuring target concentration, measuring effects of environmental conditions on the target, or screening a library for molecules that bind the target or modulate its biological function. Devices include three regions: a top lid, bottom lid, and flexible linker or hinge between them. A device has an open configuration in which the top and bottom lid are separated, and a closed configuration in which they are bound close together. Binding domains or variations of the target molecule are fixed to a device so that when the molecular event occurs, the device switches from open to closed, or vice versa, which generates a signal. Devices may carry DNA tags to enable separation of open and closed devices and barcoding for multiplexed detection.
