Title: Lipid derivatives of antiviral nucleosides, liposomal incorporation and method of use
Inventor: HOSTETLER KARL Y
IPC: C07H19/10
Filed: 1989-07-06
Granted: 1995-03-21
Abstract: Compounds are disclosed for treating AIDS,  herpes, and other viral infections by means of lipid derivatives of antiviral  agents.   The  compounds consist of nucleoside analogues  having  antiviral  activity  which  are  linked, commonly through a phosphate group at the 5' position of the pentose residue, to one of a selected group of lipids. The  lipophilic  nature  of  these  compounds  provide advantages over the use of the nucleoside analogue alone. It also makes it possible to incorporate them into the lamellar structure of liposomes, either alone or combined with similar molecules.   In the form of liposomes, these antiviral agents are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target HIV virus.   Additional  site  specificity may be incorporated  into  the  liposomes  with  the  addition  of ligands, such as monoclonal antibodies or other peptides or proteins  which  bind  to  viral  proteins.    Effective nucleoside analogues are dideoxynucleosides,  azidothymine (AZT),  and  acyclovir;  lipid groups may be glycolipids, sphingolipids,  phospholipids  or  fatty  acids.    The compounds  persist,  after  intracellular  hydrolysis,  as phosphorylated  or  non-phosphorylated  antiviral nucleosides.  The compounds are effective in improving the efficacy of antiviral nucleoside analogues by prolonging the antiviral activity after the administration of the drug has ended, and in preventing retroviral replication in HIV infections which have become  resistant to therapy with conventional forms of the antiretroviral agents.

Abstract: A sheet bending machine wherein a sheet of metal is fixed between a clamping beam and a lower beam mounted with interchangeable folding rails and wherein the bending is performed by a bending beam being swung against the projecting part of the sheet metal. The interchangeable folding rails have markings, for example, protrusions or recesses on the rear edge which cooperate with a set of members for establishment of a steering code which determines the maximum permissible bending angle for the folding rail. The code may be in the nature of a series of contacts which are opened or closed, dependent on the folding rail being used, having a recess opposite them or not. The state of the contacts may, for example, be sensed by a cam disc which curves synchronically with the swing movement of the bending beam and successively opens the contacts which are connected in parallel above them, so that a current circuit is switched when both corresponding pair of contacts are opened.
