The present invention relates to a process for making a biologically active substance or therapeutic agent free of a chlorotrityl chloride linker-resin. The process includes reacting an activated amino acid or activated amino acid derivative with a substituted or unsubstituted trityl alcohol resin to obtain a resin-CT-AA product; and, reacting the resin-CT-AA product with other building blocks of the biologically active substance or therapeutic agent to obtain said biologically active substance or therapeutic. A product created by this process is also provided herein. The invention is particularly useful to create T-20 and T-1249 therapeutics.
The present invention generally relates to articles of manufacture, such as medical devices, having a non-fouling surface comprising a grafted polymer material. The surface resists the adhesion of biological material.
