Main Research Topics

·  Viral replication inhibitors - ligands of viral proteins: mode of action, resistance, combination effects of viral inhibitors

·  Combined action of viral replication inhibitors and biological response modifiers (immunomodulators, interferon inducers, antioxidants, etc.)

·  Search for new viral inhibitors of synthetic and natural (plant, microbial, etc.) origin

·  Antiviral microbicides

·  Viruses – diabetes

·  Human papillomaviruses

·  Viruses – Balkan endemic nephropathy

·  Cancerolytic effects of parvoviruses

·  Viral proteins

Most Important Achievements

·  Discovery of new original antiviral substances effective in the treatment of viral infections in humans and domestic animals:
- Guanidine derivative - chemotherapeutic agent, inhibiting replication of adenoviruses, effective in the treatment of epidemic keratoconjunctivitis and other adenovirus conjunctivitides (widely spread viral infections of the eye). It is the first known antiadenoviral chemotherapeutic agent.
- Cyclic urea derivatives, inhibiting selectively replication of influenza and togaviruses.
- Dipyridamole - a large spectrum antiviral agent, acting via induction of endogene interferon, used for prevention of flu and other acute viral respiratory infections.

·  Development of rational approaches for selection of synergistic combinations of antimetabolites effective against herpesviruses, based on targeting of key metabolites - dGTP (ribavirin + acyclovir, mycophenolic acid + acyclovir), dTTP (amethopterin + bromovinyldeoxyuridine) or involving a virus adsorption preventing agent (dextrane sulfate + acyclovir) and elucidation the mechanisms of antiviral synergism.

·  Clearing-up of the mode of antiviral action of mopyridone on influenza A virus replication (binding to the structural M1 protein).

·  Discovery and characterization of the antiviral effect of cycluridine towards flavivirus infections, the first chemotherapeutic agent efficacious in the mucosal disease-virus diarrhea in cattle.

·  Development of the concept for low-molecular weight interferon inducers as inhibitors of the cyclic AMP phosphodiesterase, a base for directed selection of active substances.

·  Establishment and characterization of antiviral activity of a series of pure substances of plant origin.

·  Establishment of synergistic combination effect of rimantadine and oseltamivir against influenza virus A(H3N2) infection in mice.

·  Clearing-up of the drug-resistance phenomenon in enterovirus replication inhibitors interacting with the viral capsid protein VP1 – problems of the development of highly effective anti-enteroviral chemotherapy. Phenotype and molecular genetic characteristics and disoxaril resistant and dependent mutants of Coxsackie virus B1.

·  Discovery of a series of highly efficient synergistic combinations of enteroviral replication inhibitors – a perspective approach for dissolving the drug-resistance problem.

·  Establishment of the synergistic combination effect of cidofovir and idoxuridine against vaccinia virus replication.

·  Discovery of oxoglaucine: a highly effective and large-spectrum inhibitor of enterovirus replication.

·  Elucidation of the protective effect of a plant polyphenol-rich extract in the lethal murine influenza H3N2 virus infection.

·  Establishment of the anti-influenza virus effects of novel protease inhibitors from Streptomyces.

·  Determination of the role of the oxidative stress in the pathogenesis of flu and the influence of certain antioxidants of natural and synthetic origin and antivirals on this process.

·  Determination of the antiviral spectrum of the highly effective and broad-spectrum virocidal composition of new type (Manorapid Synergy®), implemented in the clinical practice as hand disinfectant.

·  Characterization of the immune status in patients with Balkan endemic nephropathy (lymphocytes phenotyping, phagocytes activity, neopterin level).

·  Establishment of data about the role of hantavirus infections in etiopathogenesis of the Balkan endemic nephropathy,

·  New proves on the diabetogenic role of neutropic viruses.

·  Proves on the role of human papillomaviruses in etiology of CIN and cervical cancer in Bulgarian population (molecular epidemiological study).

·  Proves on the cancerolytic effect of some parvoviruses.
