标题:Enzyme-catalyzed synthesis of macromolecules in organic solvents
发明人：AKKARA JOSEPH A; BRUNO FERDINANDO F
权利人:US ARMY
摘要:A method is described for a simple, fast and efficient synthesis of homopolymers and copolymers by the enzymatic ring opening polymerization of lactones and lactides. The enzyme used is an ion paired protease. The advantage of this enzymatic system is in using small amount of enzyme per monomer and lower reaction time. Homopolymers and copolymers are synthesized with molecular weights between 1000 and 4600 daltons, and dispersity as low as 1.1. The monomer conversion after 4 days, for reactions catalyzed by protease S, has reached 100%. Different initiators are used to control the rate and degree of polymerization. Synthesis of block copolymers with defined block size and crystallinity are described in this invention. These biodegradable and bioerodable polyesters and copolyesters with controlled molecular weight, dispersity and crystallinity have applications in medical, drug, cosmetic and food industries.

摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.

摘要:The invention relates to an efficient method for synthesizing self-assembling artificial proteins (SAPs) utilizing a catalytic host-guest system. The process involves encapsulating hydrophobic probes with cyclodextrin, performing site-specific protein bioconjugation, and employing a second catalysis cycle for enhanced labeling. SAPs produced through this method are versatile and find applications in therapeutic delivery and diagnostics. The process is simplified, scalable, cost-effective, and environmentally sustainable, addressing the challenges of traditional SAP synthesis. By offering improved yield, functionality, and structural integrity, this invention advances the potential of SAPs in medical and industrial fields.
