HIV with soy sauce

Specialists of a Japanese company in search of a flavor enhancer for soy sauces accidentally discovered a molecule that suppresses HIV replication. We hope that it is not added to sauces – the antiretroviral drug will certainly have a lot of side effects. And EFdA tests for efficiency and safety have already begun.
