  • Patent number: 4540830
    Abstract: This invention relates to substituted isopentenyl phenyl compounds and their use as anti-juvenile hormones. The compounds have been found effective in the control of insects by inhibiting the actions of juvenile hormones. Such compounds act to induce precocious maturation of immature insects resulting in a reduction in the ecological impact of the insect. Additional effects which have been obtained include sterilization of mature insects. Based on previous research it is also believed these compounds will cause interruption of embryogenesis in insect eggs, the induction of diapause in insects and the prevention of sex pheromone secretion in insects.

  • Patent number: 4540799
    Abstract: Perfluoro(2,2-dimethyl-1,3-dioxole) forms oligomers on standing in the presence of an ether. The preferred ethers are aliphatic and cycloaliphatic, especially tetrahydrofuran. Free radical generators, especially peroxydicarbonates, may be added to the reaction medium. The oligomers have a degree of polymerization of about 2-8. They are useful as lubricants, hydraulic fluids, heat transfer agents, and plasticizers, and as intermediates to oligomeric acid fluorides and acids, which acids are useful surfactants.

  • Patent number: 4539413
    Abstract: The present invention concerns a novel process for the production of new chemical compounds of the general formula: ##STR1## in which: R.sub.1 and R.sub.2 may be identical or different and represent a hydrogen or halogen atom or else a lower alkyl, lower alkoxy, nitro or acetyl group andR represents a lower alkyl or lower aralkyl group, such as benzyl.These compounds are useful in therapy for the treatment of hypertension and cardiac arrhythmia.The novel process involves reaction of a 2-hydroxymethyl-1,4-benzodioxan with epichlorohydrin to produce an intermediate glycidyl ether, which is then reacted with a primary amine to produce the final 3-amino-1-[(1,4-benzodioxan)-2-yl-methoxy]-2-propanol or an acid addition salt thereof.

  • Patent number: 4539313
    Abstract: 3'-deoxyadenosine 5'-triphosphate is oligomerized to form (2'-5')-oligo (3'-deoxyadenylate) by incubation with adenosine triphosphate: (2'-5')-oligo adenosine adenyl transferase, in the presence of an inert support carrying a double stranded polynucleotide. The (2'-5')-oligo (3'-deoxyadenylate) is digested with a suitable phosphatase to remove the terminal phosphate groups. The thus produced corresponding 3'-deoxyadenosine compound is an anti-viral material effective against Herpes simplex infection and effective in inhibiting the transformation of cells infected with Epstein Barr virus.
