The invention relates to the development of drugs intended for the prophylaxis and/or treatment of viral diseases caused, in particular, by herpes viruses. What are proposed are complex compounds of germanium having the general structural formula:
Ge.sub.x[AD][CA].sub.y[AA].sub.2   (1), where AD is a derivative of a nitrogenous base of the purine series that has antiviral activity and can be selected from guanine derivatives, such as acyclovir, valacyclovir, gancyclovir and pencyclovir, or from adenine derivatives, such as vidarabine; CA is a hydroxycarboxylic acid which can be selected from acids such as (but not limited to) citric acid, lactic acid and malic acid; AA is an amino acid which can be selected from various a-amino acids, such as arginine, gylcine, lysine and threonine, and where x=1-2, y=2-4 and z=0-2. Complex compounds of germanium have a high level of antiviral and immune-stimulating activity and are readily soluble in water. The above mentioned compounds are produced by producing an aqueous suspension of germanium dioxide, adding a hydroxycarboxylic acid, a derivative of a nitrogenous base of the purine series and, optionally, but preferably, an amino acid thereto, heating the mixture produced at a temperature of 40-100° C. for 3-14 hours while stirring and removing the water from the solution, thus producing a complex compound of germanium.

The present invention relates to a drug delivery system, comprising: a drug-loaded carbon nanotube formed by a carbon nanotube and a drug molecule adsorbed on the surface of the carbon nanotube, a modifying material capable of enhancing water solubility and biocompatibility of the drug delivery system, and a targeting molecule. The present invention further relates to preparation and use of the drug delivery system. The present invention provides a new strategy for selectively targeting and effectively eliminating cancer stem cells, which is conducive to fundamentally preventing recurrence and metastasis of a cancer induced by cancer stem cells.

The invention relates to ultrasmall, monodisperse nanoparticles comprising silicon dioxide to the surface of which at least one antigen is attached. The nanoparticles can be used for the immunoprophylaxis or immunotherapy of cancer. The invention also relates to a method for the targeting of antigens at antigen-presenting cells and for the activation of the immune system, where the efficiency of targeting and/or immunoactivation are set via the particle characteristics. The invention also relates to a method for the active and passive immunization of a mammal.

The present invention describes how a MAb specific to a viral or cancer antigen can be linked to a novel Zn porting peptide that is engineered to load ionic Zn absent requirement for biological catalysis, carry Zn stably through the circulation, release payload proximal to diseased cells, deliver its Zn cargo intracellularly due to ionophore activity, and release Zn intracellularly. As specifically designed for COVID-19, the payload can be released by furin cleavage, and the Zn released intracellularly by cleavage at a 3CL major COVID protease site replacing sequences naturally found in alpha defensin-5, as one example, or by many other variations encompassing this design. The peptide's entry and intracellular Zn release can be further facilitated by the insertion of an arginine-lysine rich membrane translocation sequence at its amino or carboxyl terminus. The design provides a novel unifying strategy for preventing and treating COVID-19 (SARS-CoV-2) infection, other coronaviral infections, influenza infections, and many cancers.
