专利号:US-10975069-B2 优先权日:2014-04-01 标 题 :Sigma-2 receptor ligand drug conjugates as antitumor compounds, methods of synthesis and uses thereof 发明人:HAWKINS WILLIAM; MACH ROBERT; SPITZER DIRK; VANGVERAVONG SUWANNA; VAN TINE BRIAN 权利人:UNIV WASHINGTON 摘要:Methods and compositions for treating cancers such as pancreatic cancer and synovial sarcoma are disclosed. Compounds comprising a sigma-2 receptor-binding moiety and a ferroptosis-inducing moiety are described, such as the methanesulfonate salt of a compound of structural Formula IV, n n, wherein n is an integer chosen from 1, 2, 3, 4, and 5, and R 2 is H or methyl. At least one described molecular species exhibits an IC 50 value below 5 μM against human pancreatic cancer cells in vitro. Administration of this species promoted shrinkage of pancreatic cancer tumors in a murine model system in vivo. It led to a 100% survival of experimental animals over a time course in which control therapies provided only 30% or 40% survival. Methods of synthesis of molecular species are also disclosed.
专利号:WO-2013087821-A1 优先权日:2011-12-15 标题:Overproduction of jasmonates in transgenic plants 发明人:CHAMPION ANTONY 权利人:INST RECH DEVELOPPEMENT IRD 摘要:La present invention relates to the use of a nucleic sequence allowing the synthesis of Gh ERF-IIa, Gh ERF-IIb or Gh ERF-IIc in a plant in order to induce, in the plant, an overproduction or accumulation of jasmonic acid and/or OPDA. The accumulation of jasmonic acid and/or OPDA confers, in particular, to the transformed plant an improved resistance to bioagressors. The nucleic sequences, transformation methods and transformed plants according to the invention may also been used for the production of pharmaceutically important secondary metabolites whose synthesis is induced by jasmonates.
专利号:US-6890732-B1 优先权日:1998-05-08 标题 :Nucleic acid molecules which code for enzymes derived from wheat and which are involved in the synthesis of starch 发明人:LOERZ HORST; LUETTICKE STEPHANIE; BLOCK MARTINA 权利人:BAYER CROPSCIENCE GMBH 摘要:Nucleic acid molecules are described which encode wheat enzymes involved in starch synthesis in plants. These enzymes are soluble wheat starch synthases. The invention furthermore relates to vectors and host cells which contain the above-described nucleic acid molecules. In particular to transformed plant cells and plants which can be regenerated from these and which have an increased or reduced activity of the soluble starch synthases according to the invention.

The synthesis of sulfated alkylated and fluoroalkylated SAGEs is also described.
专利号:US-8487159-B2 优先权日:2008-04-28 标题:Production of polyhydroxybutyrate in switchgrass 发明人:SOMLEVA MARIYA N; SNELL KRISTI D; BEAULIEU JULIE; PEOPLES OLIVER P; GARRISON BRADLEY; PATTERSON NII 权利人:SOMLEVA MARIYA N; SNELL KRISTI D; BEAULIEU JULIE; PEOPLES OLIVER P; GARRISON BRADLEY; PATTERSON NII; METABOLIX INC 摘要:Transgenic plants, plant material, and plant cells for synthesis of polyhydroxyalkanoates, preferably poly(3-hydroxybutyrate) (also referred to a as PHB) are provided. Preferred plants that can be genetically engineered to produce PHB include plants that do not normally produce storage products such as oils and carbohydrates, and plants that have a C 4 NAD-malic enzyme photosynthetic pathway. Such plants also advantageously produce lignocellulosic biomass that can be converted into biofuels. An exemplary plant that can be genetically engineered to produce PHB and produce lignocellulosic biomass is switchgrass, Panicum virgatum L. A preferred cultivar of switchgrass is Alamo. Other suitable cultivars of switchgrass include but are not limited to Blackwell, Kanlow, Nebraska 28, Pathfinder, Cave-in-Rock, Shelter and Trailblazer.
