This document discusses drug and vaccine discovery efforts for monkeypox. It outlines the workflow for drug repurposing targeting monkeypox, identifying potential existing drugs that could be effective. These include tecovirimat, brincidofovir, and others. It also describes the process for vaccine development, noting existing smallpox vaccines may prevent monkeypox. Finally, it lists the services and products available from Creative Biolabs to support anti-monkeypox drug and vaccine discovery.

4. A new zoonotic illness called monkeypox is brought on by the monkeypox virus (MPXV),
which belongs to the family Poxviridae's Orthopoxvirus genus. Monkeypox symptoms
include a rash, fever, and swelling of the lymph nodes. Additionally, patients may
experience a variety of side effects, such as secondary bacterial infections, respiratory
problems, bronchopneumonia, gastrointestinal problems, dehydration, sepsis, encephalitis,
and corneal infections with subsequent vision loss. No specific treatment for a monkeypox
virus infection currently exists.

5. Mutations have enabled the virus to grow stronger and smarter,
evading antiviral drugs and vaccines. To better identify and
control the current monkeypox outbreak, efforts to develop
drugs and vaccines are critical.

7. Drug repurposing is also known as drug repositioning or therapeutic switching. This method is used to
find novel therapeutic agents among the existing FDA-approved clinically used drug molecules. It is
considered an efficient approach to developing drug candidates with new pharmacological activities or
therapeutic properties. As drug discovery is a costly, time-consuming, laborious, and highly risky process,
the novel approach of drug repositioning is employed to increase the success rate of drug development.
Repurposing old drugs seems like a good idea against the monkeypox virus due to the emergency of the
actual situation.
