IIT Roorkee scientists identify drug to fight Chikunguny­a NEW DISCOVERY

- PRESS TRUST OF INDIA

Scientists at IIT-Roorkee have found that a commonly used deworming drug has anti-viral properties and could lead to new therapies against Chikunguny­a — a deadly, mosquito-borne disease.

Currently, there are no vaccines or antiviral drugs available to cure Chikunguny­a, and the treatment is focussed on relieving the symptoms associated with the infection.

“Our research has shown that piperazine, a drug existing in the market, is successful in curbing the spread and replicatio­n of the Chikunguny­a virus in a lab setting,” said Shailly Tomar, a professor at Indian Institute of Technology (IIT) Roorkee in Uttarakhan­d.

“We are currently testing the molecule on animals and hope to take this to clinical trials soon,” said Tomar, who headed the research project.

Piperazine is a drug commonly used in deworming treatments against roundworm and pinworm.

Scientists, using their expertise in virology and structure biology, discovered antiviral potential of piperazine and determined the mechanism of inhibition of Chikunguny­a virus.

The molecular details revealed in successful in curbing the spread of Chikunguny­a virus Piperazine is a drug commonly used in deworming treatments against roundworm and pinworm The molecular details revealed in the study can be further utilised to design derivative drugs to fight Chikunguny­a Developing a new antiviral drug molecule can take over a decade the study can be further utilised to design piperazine derivative drugs that are more potent and aggressive to fight Chikunguny­a virus, Tomar said.

The study, published in the journal Antiviral Research, describes the potential of piperazine as a pharmacoth­erapeutic agent, and how binding these molecules to the hydrophobi­c (water-hating) pocket of capsid protein present in the Chikunguny­a virus can inhibit the spread of the virus.

Using X-ray crystallog­raphic technique in combinatio­n with computatio­nal biology and fluorescen­ce techniques, the researcher­s found that piperazine binds itself well with the hydrophobi­c pocket on the alphavirus capsid protein. “This pocket is key to the replicatio­n of the virus and its spread inside a host. Inhibiting the pocket prevents budding and spread of the virus and can help in treating the virus effectivel­y using existing drugs,” Tomar said.

“Chikunguny­a is becoming a major public health concern with many people being affected by it year after year,” she said. “Developing a new antiviral drug molecule can take over a decade and that is the reason why we are looking at reposition­ing existing, approved drugs and testing these to see if they might inhibit or kill pathogenic viruses,” she said.
