Drug discovery from marine natural products has enjoyed a renaissance in the past few years. Ziconotide (Prialt; Elan Pharmaceuticals), a peptide originally discovered in a tropical cone snail, was the first marine-derived compound to be approved in the United States in December 2004 for the trea...
The modification efforts are mainly in three categories: coating, reacting and heating. The coating process modifies the raw material by adding hydrophobic reagents or polymers to get a hydrophobic surface. Examples are shown in U.S. Pat. No. 4,519,918, U.S. Pat. No. 4,925,343, U.S...
3.1.2Semisynthetic polymers Semisynthetic polymers are obtained by the simple chemical or physical treatment ofnatural polymersto improve their physical properties such as lustrous nature andtensile strength. For example,cellulose acetate(rayon),cellulose nitrate, and vulcanized rubber are used in making ti...
