Polycyclo Ring System Having The Hetero Ring As One Of The Cyclos Patents (Class 549/348)
  • Patent number: 11559556
    Abstract: Methods disclosed herein provide for an environmentally-friendly approach that employ citric extracts from fruits as unique reducing and stabilizing agents for making a tellurium nanomaterial. A particular method of making a tellurium nanomaterial includes combining citrus fruit extract with a tellurium salt to form a mixture of citrus fruit extract and dissolved tellurium salt; and heating the mixture of citrus fruit extract and dissolved tellurium salt, thereby making the tellurium nanomaterial. The resulting nanoparticles exhibit enhanced and desirable biomedical properties toward treatment of both infectious diseases and cancer.

  • Patent number: 8801811
    Abstract: A stabilized nano-Fe6-iron-crown ether complex is formed by preparing a solution of an iron salt and an oligomer crown compound in dialkylamine or diethylamine. Sodium tetrahydroboron (NaBH4) and dialkylamine or ethylendiamine are added at a temperature of 0-10° C. The mixture is heated to room temperature and boiled, thereby converting the formed iron (II)-borhydride complex (Fe(BH4)2) to a crown ether-iron-hydride complex [CWFe06].(2H)6. At higher temperature this last complex is converted to the Fe06-crown nanocomposite complex. The prepared nanoparticle Fe6° complex may be stabilized by inclusion into a cavity of a macrocyclic compound, and may be (1) added to diesel fuel to reduce NOx emissions upon combustion of that fuel; (2) added to lubricating oils as an anti-corrosion additive; and (3) used as an additive to secondary recovery processes within liquid hydrocarbon formations to increase the sweep efficiency and recovery factor of water-flooding operations.

  • Publication number: 20130030044
    Abstract: This invention relates to the synthesis of certain novel Baylis-Hillman adducts of artremisinin derived aldehyde 2[10??-deoxoartemisininyl]-ethanal. The capabilities of introduction of three functional groups into a molecule in one step using Baylis-Hillman reaction encouraged us to synthesize some highly functionalized derivatives of artemisinin.
