"Now we have identified a compound which can disrupt this essential virus-host cell interaction which in turn prevents herpesviruses replicating and producing infectious particles."
The approach the researchers used was unique as it targeted the enzyme activity of a key component of the cellular human TREX complex, known as UAP56.
Inhibiting this activity prevented the remodelling of the human TREX complex which stopped the interaction with the viral protein.
Dr Foster's team performed a virtual screen of thousands of compounds to identify potential inhibitors. These were then tested for their ability to stop herpesvirus replication without damaging the host cell.
"However, further testing showed that the compound was also effective against a range of other herpesviruses which all use the same mechanism to replicate in their host cell, which is very encouraging."
Examples include Herpes simplex virus, which causes cold sores and genital lesions as well as human cytomegalovirus, which is associated with glandular fever and a range of conditions in immunocompromised patients and congenitally infected newborns.
Dr Foster said: "We still have a lot of work to do, but bringing together a target point and a compound is a significant finding. Now our job is to improve the quality and potency of the compound before it can operate as a future antiviral drug."
The research so far has been supported in parts by Worldwide Cancer Research, Wellcome Trust, and Biotechnology and Biosciences Research Council.
The next stage of Professor Whitehouse and Dr Foster's work, which is funded by a Cancer Research UK drug discovery award, will work towards improving the effectiveness and safety of the compound.
The image above shows a molecular level model of a normal human protein and the newly discovered inhibitor compound, and where on the protein the research team anticipate the two will bind together.
