Nitric Oxide-Releasing Hydrophobic Polymers: Preparation, Characterization, and Potential Biomedical Applications

Reynolds, Melissa M., Frost, Megan C., Meyerhoff, Mark E.·2004·Free Radical Biology and Medicine

Abstract

The synthetic methods used recently in this laboratory to prepare a variety of novel nitric oxide (NO)-releasing hydrophobic polymers are reviewed. Nitric oxide is a well known inhibitor of platelet adhesion and activation. Thus, such NO release polymers have potential applications as thromboresistant coatings for a large number of blood-contacting biomedical devices (e.g., in vivo sensors, arteriovenous grafts, stents, catheters, extracorporeal circuits). The approaches taken to prepare NO releasing poly(vinyl chloride) (PVC), silicone rubber (SR), polymethacrylate (PM), and polyurethane (PU) materials are grouped into three categories: (1) dispersion/doping of discrete diazeniumdiolated molecules within the polymeric films; (2) chemical derivatization of polymeric filler microparticles (e.g., silicon dioxide, titanium dioxide) to possess NO release chemistry and then their dispersion within the hydrophobic polymers; and (3) covalent attachment of NO release moieties to polymer backbones. Specific chemical examples of each of these approaches are summarized and the advantages and disadvantages of each are discussed. Other related work in the field of NO release polymers is also cited. It is further shown that several of the NO-releasing polymeric materials already prepared exhibit the expected improved thromboresistivity when tested in vivo using appropriate animal models.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Three main strategies for increasing NO bioavailability are exercise/diet, drugs that alter enzymatic NO production, and modified polymeric materials that deliver NO exogenously.

    “There are three main strategies for increasing NO bioavailability: 1) by participating in physical exercise and controlling certain dietary components (e.g., nitrate-rich diet);132,133 2) by administrating drugs that alter the enzymatic production of NO through nitric oxide synthases (NOSs) and increase the biosynthesis of NO endogenously;117 and 3) by using modified polymeric materials that can”
  • Meyerhoff and coworkers were among the first to link NO donors to particle fillers or to polymer backbones such as PVC, polyurethane, and silicone rubber.

    “Meyerhoff and coworkers were among the first to link these NO donors to particle fillers (such as fumed silica particles236) or to the polymer backbone of polymers such as PVC,34,237 polyurethane (PU),34,110,233 and silicone rubber (SR).238”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
