专利号:US-10308588-B2 优先权日:2014-12-15 标 题 :Synthesis of amides and amines from aldehydes or ketones by heterogeneous metal catalysis 发明人:CÓRDOVA ARMANDO; PALO-NIETO CARLOS; AFEWERKI SAMSON 权利人:ORGANOFUEL SWEDEN AB 摘要:A mild and efficient synthesis of primary amines and amides from aldehydes or ketones using a heterogeneous metal catalyst and amine donor is disclosed. The initial heterogeneous metal-catalyzed reaction between the carbonyl and the amine donor components is followed by the addition of a suitable acylating agent component in one-pot, thus providing a catalytic one-pot three-component synthesis of amides. Integration of enzyme catalysis allows for eco-friendly one-pot co-catalytic synthesis of amides from aldehyde and ketone substrates, respectively. The process can be applied to asymmetric synthesis or to the co-catalytic one-pot three-component synthesis of capsaicin and its analogues from vanillin or vanillyl alcohol. A co-catalytic reductive amination/dynamic kinetic resolution (dkr) relay sequence for the asymmetric synthesis of optically active amides from ketones is disclosed. Implementation of a catalytic reductive amination/kinetic resolution (kr) relay sequence produces the corresponding optically active amide product and optical active primary amine product with the opposite stereochemistry from the starting ketones.

专利号:US-2002022022-A1 优先权日:2000-05-19 标题 :Inhibition of cell proliferation and matrix synthesis by antioxidants and NAD(P)H oxidase inhibitors 发明人:SHI YI; ZALEWSKI ANDREW 摘要:The present invention is directed to a method for the prophylactic and therapeutic treatment of diseases or disorders associated with the abnormal proliferation and extracellular matrix synthesis of smooth muscle cells (SMC) and fibroblasts due to activation of NAD(P)H and/or increased ROS generation. The method involves the administration of an NAD(P)H oxidase inhibitor(s) and/or antioxidant(s) to a mammal in an amount sufficient to treat the disease or disorder prophylactically or therapeutically. The NAD(P)H oxidase inhibitor inhibits the synthesis or translocation of NAD(P)H subunits, thereby blocking the generation of intracellular reactive oxygen species (ROS) and thus the proliferation and extracellular matrix synthesis of SMC and fibroblasts. Similarly, the administration of antioxidants blocks the generation of intracellular ROS, thereby inhibiting SMC and fibroblast proliferation and extracellular matrix synthesis. In addition to the prevention and treatment of vascular disease, such as atherosclerosis, graft disease, and restenosis, NAD(P)H oxidase inhibitors and antioxidants may be useful for the prevention and treatment of other conditions by decreasing cell proliferation and extracellular matrix synthesis associated therewith. These conditions include arthritis, keloid formation, cancer, tissue and organ fibrosis, and complications related to organ transplantation, metabolic syndrome, and radiation therapy.
