The Project

The respiratory influenza viruses A and B remain a significant global health challenge by causing annual seasonal flu, occasional epidemics and pandemics. These threats in combination with the propensity of influenza viruses to develop resistance to commonly used drugs require the continued development of new antiviral agents. This project aims at the identification of novel anti-influenza agents from natural sources targeting two influenza virus proteins, namely the neuraminidase (NA) and the nucleoprotein (NP). These two targets are highly conserved and cover various stages of viral life cycle. Novel agents against NA and NP shall help to overcome resistance and to develop multidrug strategies.

Inhibition of the influenza virus NA impedes the release of newly formed virions from infected cells and causes viral aggregation, thus halting the spread of infection. The high amount of data and information of this established drug target and its ligands will be used as starting point to apply structure-based  computational methods to cope with the flexibility of the NA binding site (Grienke et al. 2010, doi 10.1021/jm901440f), and to scrutinize its ligand-target interactions for the discovery of ligands that overcome the influence of mutational changes conferring drug resistance.

In contrast to NA, the influenza nucleoprotein (NP) only recently emerged as druggable target for potential small molecule therapies. Ligands of this abundantly expressed protein are found to impede influenza A virus replication by triggering the aggregation of NP and inhibition of its nuclear accumulation. Based on previously published compounds interacting on the NP, a ligand-based approach will be the rationale for the target-oriented identification of putative NP-ligands from the rich pool of secondary metabolites.

The selection of natural starting materials for phytochemical investigations will depend on

(i) virtually predicted hits form ligand- and structure-based approaches

(ii) previously determined anti-influenza or anti-viral activities of herbal remedies or constituents thereof (with unknown mechanism of action) and

(iii) empirical knowledge of antiviral herbal remedies form traditional medicine.

Based on these selection criteria, in depth analytical and phytochemical studies will be performed with most promising natural starting materials for each target, primarily from plant origin. Fractions enriched with virtually predicted hits and finally isolated and identified compounds will be provided for assaying on the respective anti-influenza targets and determination of their antiviral efficacy.

We aim to

(i) explain the anti-influenza molecular mechanism of traditionally approved herbal remedies,

(ii) identify naturally derived drug leads for novel NA-inhibitors with lower risk to develop drug resistance, and

(iii) enrich the pool of small molecule ligands for the innovative anti-influenza target NP in an effort to discover agents for a rapidly evolving pathogen.
