Process are described for the delivery of a polynucleotide to a cell. The process comprises forming a salt stable complex between the polynucleotide and a cationic surfactant. Ternary complexes are also made by associating an amphipathic compound with the binary complex. The resultant complexes are suitable for delivery of the polynucleotide to cells in vitro and in vivo.
Sulfenyl groups are attracting interest as masking/protectinggroups for pyrroles. A facile one-step synthesis of sulfenyl pyrroles,involving the reaction of pyrroles with N-(aryl-and alkyl-thio)phthalimides in the presence of MgBr 2 ,is reported and the methodology extends to include sulfinyl pyrroles.The one-step procedure gives good yields and is more efficient andpractical than current multistep
A complex is described that is deliverable to a cell comprising inserting a nucleic acid or other cargo into a reverse micelle. The reverse micelle has the property to compact the nucleic acid for easier delivery.
Novel pesticidal N-hydrocarbylsulfenyl derivatives of N-alkyl-N'-aryl formamidines are disclosed with novel compositions thereof and methods of their use in controlling invertebrate pests, particularly insects and acarina. Certain of the novel compounds are particularly effective miticides.
