Introduction: Several viral infections cause life-threatening consequences in humans, making them the most serious public health concerns. Despite the fact that several antiviral medicines are available on the market, there is no full treatment for many important viral infections. To date, antiviral medicines have significantly reduced the spread of epidemics, but their continued use has resulted in the creation of drug-resistant variants throughout time. As a result, the development of new, safe, and efficient antiviral drugs is critical.
Areas covered: This review covered reports in the patent literature in the period 2014 to the first quarter of 2021 on the antiviral activities of thiazole derivatives. These molecules were reported to inhibit a wide range of viruses including influenza viruses, coronaviruses, herpes viruses, hepatitis B and C, bovine viral diarrhea virus, chikungunya virus and human immunodeficiency viruses.
Expert opinion: The most bioactive molecules can be used as lead structures for the development of new thiazole compounds with potent and selective antiviral activity. In addition, more efforts are needed to better understand the host-virus interactions for the discovery and development of new therapeutic agents and creative treatment strategies that are supposed to improve rates of clinical cure of the serious viruses.
Keywords: anti-HBV; anti-HCV; anti-viral; biological activity; thiazoles.
