Abstract

Infections by alpha viruses represent a very serious health problem especially in developingcountries where the precarious public health system is already over stressed. A leading example is infection by the Chikungunya virus which results in considerable social and economic trauma and requires urgent attention. The lack of efficacious treatments is compounded by potential coinfection by Chikungunya and Mayaro virus, which exacerbates and magnifies the problem since both trigger similar reactions and analogous clinical symptoms. The cleavage of the Chikungunyaand Mayaro nsP-polyproteins, by the virus nsP2 cysteine protease is crucial for viral replication. The identification and characterization of specific simultaneously acting inhibitors against the Chikungunya and Mayaro virus nsP2 cysteine protease is potentially relevant for the development of drugs and the aim of this project. This proposal is an extension of the ongoing post-doctoral research and aims to apply new techniques and technologies available at the excellent laboratory led by Prof. D. Willbold to develop novel inhibitors with potential clinical applications.
