The ongoing COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) became a globally leading public health concern over past two years. Despite development and administration of multiple vaccines, mutation newer strains challenges to universal immunity has shifted focus lack efficacious drugs for therapeutic intervention disease. As with SARS-CoV, MERS-CoV, other non-respiratory viruses, flavonoids present themselves as promising given their success in silico, vitro, vivo, more recently, clinical studies. This review focuses on data from vitro studies analyzing effects various key SARS-CoV-2 targets presents an analysis structure-activity relationships same. From 27 primary papers, 69 were investigated activities against targets, ranging 3C-like protease (3CLpro) less explored nucleocapsid (N) protein; most quercetin myricetin derivatives, baicalein, baicalin, EGCG, tannic acid. We further silico featuring list involving potential flavonoid-rich extracts combination synthetic or polyphenols suggest prospects future SARS-CoV-2.

Neoadjuvant immunotherapy has the potential to enhance clinical outcomes by increasing anti-tumor immune responses in presence of abundant tumor-derived antigen an microenvironment that not been exposed previous therapy. The current mainstay advanced head and neck squamous cell carcinoma (HNSCC) treatment remains surgery radiotherapy with/without conventional chemotherapy. Despite this multi-modality treatment, human papillomavirus (HPV)-negative HNSCC shows poor prognosis. Treatment intensification with neoadjuvant (induction) chemotherapies platinum drugs are insufficient significantly prolong overall survival. Although only 15-20% patients benefit, immunotherapies have approved widely used for recurrent metastatic HNSCC. These successes led checkpoint blockade therapies being testing earlier settings. Recent trials show promising results methodology change algorithm This overview examines history approaches HNSCC, especially focuses on recent topics
