The SARS-CoV-2 pandemic is a worldwide public health emergency. Despite the beginning of a vaccination campaign, the search for new drugs to appropriately treat COVID-19 patients remains a priority. Drug repurposing represents a faster and cheaper method than de novo drug discovery. In this study, we examined three different network-based approaches to identify potentially repurposable drugs to treat COVID-19. We analyzed transcriptomic data from whole blood cells of patients with COVID-19 and 21 other related conditions, as compared with those of healthy subjects. In addition to conventionally used drugs (e.g., anticoagulants, antihistaminics, anti-TNFα antibodies, corticosteroids), unconventional candidate compounds, such as SCN5A inhibitors and drugs active in the central nervous system, were identified. Clinical judgment and validation through clinical trials are always mandatory before use of the identified drugs in a clinical setting.

Plant diseases caused by bacteria affect the yield of crop, greatly reduce the quality of food, and thus posing a great threat to food safety. To fill the gap that no report about ClpP inhibitor is applied in agri-food production field, engineering natural-product repurposing strategy, 55 of natural products were screened using the combination of ClpP inhibitors of Xanthomonas oryzae pv. oryzae (Xoo) screening assay and anti-Xoo activity experiment.

Ferroptosis is an iron-dependent form of regulated cell death characterized by lethal lipid peroxidation and implicated in various human diseases. Despite intensive research, clinically applicable ferroptosis inhibitors remain unavailable. In this study, we identify formoterol, a β-adrenergic agonist widely used to treat asthma and COPD, as a potent and selective ferroptosis inhibitor through scaffold-based screening of FDA-approved drugs.

Polycystic kidney disease (PKD) is characterized by the development of fluid-filled kidney cysts and relentless progression to renal failure. Current treatments have adverse effects and limited efficacy, enhancing the need for improved therapeutics. Here, we provide a proof of concept for the use of dimeric immunoglobulin A (IgA) (dIgA) monoclonal antibodies (mAbs) to target epithelial-enclosed cysts, by exploiting their ability to transcytose via the polymeric immunoglobulin receptor highly expressed on renal cyst-lining cells.

The emergence of antibiotic resistance continues to pose a significant global challenge. Drug repurposing, wherein existing therapeutics are evaluated for new applications, offers a promising strategy to address this issue. Farnesyltransferase inhibitors (FTIs), initially developed for cancer therapy, have demonstrated antimicrobial activity against several gram-positive bacteria.
