The antiviral preparation 1-morpholinomethyltetrahydro-2(1H)-pyrimidinone (abbreviation DD-13) inhibiting reproduction of certain enveloped viruses belonging to groups of orthomyxoviruses and alphaviruses, influenza type A viruses among them, inhibited adsorption and insertion of influenza virus M protein into model bilayer lipid membranes. The preparation did not interact directly with lipid bilayers but, after pretreatment of M protein with it, inhibited M protein interaction with the membranes: adsorption and insertion into the bilayer DD-13 did not affect the interaction of influenza virus surface glycoproteins with the model lipid membranes. It is concluded that the DD-13 preparation, not interacting with the membranes directly, in native systems may modify the protein-lipid interactions at the stages of virus penetration into the cell, penetration of M protein-coated nucleocapsid into the cell nucleus through the nuclear membrane, as well as at the stage of virus particle assembly on the plasma membrane of the infected cell.

UI	MeSH Term	Description	Entries
D008051	Lipid Bilayers	Layers of lipid molecules which are two molecules thick. Bilayer systems are frequently studied as models of biological membranes.	Bilayers, Lipid,Bilayer, Lipid,Lipid Bilayer
D009980	Influenza A virus	The type species of the genus ALPHAINFLUENZAVIRUS that causes influenza and other diseases in humans and animals. Antigenic variation occurs frequently between strains, allowing classification into subtypes and variants. Transmission is usually by aerosol (human and most non-aquatic hosts) or waterborne (ducks). Infected birds shed the virus in their saliva, nasal secretions, and feces.

D000327	Adsorption	The adhesion of gases, liquids, or dissolved solids onto a surface. It includes adsorptive phenomena of bacteria and viruses onto surfaces as well. ABSORPTION into the substance may follow but not necessarily.	Adsorptions
D000998	Antiviral Agents	Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.

D014763	Viral Matrix Proteins	Proteins associated with the inner surface of the lipid bilayer of the viral envelope. These proteins have been implicated in control of viral transcription and may possibly serve as the "glue" that binds the nucleocapsid to the appropriate membrane site during viral budding from the host cell.
