Abstract
Disclosed are novel polymers derivatized with at least one —NOx group per 1200 atomic mass unit of the polymer. X is one or two. In one embodiment, the polymer is an S-nitrosylated polymer and is prepared by reacting a polythiolated polymer with a nitrosylating agent under conditions suitable for nitrosylating free thiol groups. The polymers of the present invention can be used to coat medical devices to deliver nitric oxide in vivo to treatment sites.
Claims12
A polymer derivatized with at least one —ONO group per 1200 atomic mass units of the polymer.
An article capable of releasing NO wherein the article is coated with a polymer comprising at least one —ONO group per 1200 amu of the polymer.
A method of delivering nitric oxide to a treatment site in a subject or to a bodily fluid comprising the steps of:
- a) providing a medical device coated with a polymer having at least one —ONO group per 1200 amu of the polymer;
- and
- b) implanting the medical device at the treatment site or contacting the bodily fluid with the medical device.
A method of preparing an article capable of releasing NO comprising coating an article with at least one —ONO group per 1200 amu of the polymer.
A method of replacing a loss of NO groups from an O-nitrosylated polymer at a treatment in an individual, said method comprising the step of administering to the individual a regenerating effective amount of a nitrosylating agent.
