专利号:US-2023089537-A1 优先权日:2021-09-20 标题:Dietary supplement and method for synthesis of same 发明人:WYNN JASON R 权利人:StrongCell LLC 摘要:A dietary supplement and method for synthesis of the same are disclosed. In one embodiment of the method, an NADH component is provided which includes NADH from about 0.1% to about 0.5% blended with water from about 40% to about 84% both by weight of the dietary supplement. A supplement component from about 9% to about 99% by weight of the dietary supplement is also provided. The supplement component may include collagen in about 2% to about 10%, vitamins in about 0.00001% to about 3%, and minerals in about 0.000002% to about 0.5% all by weight of the dietary supplement. A mixed component is formed by mixing the NADH component with the supplement component at ambient conditions. The mixed component is a liquid at ambient conditions having a pH of less than 4.0. The mixed component is subjected to a cold fill production process.

The dietary supplements can also include an appropriate neurotransmitter, such as an amino acid. When administered through the oral mucosa, increases in levels of the deficient neurotransmitters and relief from deficiency symptoms are obtained.
专利号:US-11325888-B2 优先权日:2017-08-11 标 题:Method for the synthesis of monoprotected bifunctional prodrugs and antibody drug conjugates based thereon as well as a method for preparing antibody drug conjugates 发明人:TIETZE LUTZ F 权利人:GEORG AUGUST UNIV GOETTINGEN STIFTUNG OEFFENTLICHEN RECHTS 摘要:The present invention relates to a method for the synthesis of compounds useful in the preparation of antibody drug conjugates (ADC), namely, monoprotected dimeric bifunctional prodrugs based on duocarmycin analogs. In a further aspect, compounds obtained by the method according to the present invention are provided. The monoprotected bifunctional prodrug is used for preparing antibody drug conjugates composed of an antibody moiety and the monoprotected bifunctional prodrug. The antibody compound conjugates thus obtained are provided. Further, a method of preparing an antibody drug conjugate composed of two identical or two different antibody moieties is provided as well as the antibody compound conjugate containing two different antibody moieties accordingly. These conjugates can be used in pharmaceutical compositions, in particular, for use in treatment of tumors, e.g. for use in ADC therapy.
