Writingoriginal draft preparation: GZ, VT, and PS. respiratory distress syndrome has been recently exhibited in P53 knockout mice that brought on more severe inflammatory responses when challenged with LPS compared to wild type littermates (Uddin et al., 2020). In this line, both RSV-mediated cell survival and inflammatory burden resulted antagonized by Nutlin-3 treatment in cell models (Groskreutz et al., 2007). The potential of MDM2 antagonists in attenuating the association between cell-senescence and inflammatory processes has been recently investigated at preclinical level (Wiley et al., 2018). Small-molecules inhibitors of MDM2 such as Nutlin-3 and MI-63 by promoting p53 survival can be useful to reduce the so-called senescence-associated secretory phenotype and lowering in particular IL-6 secretion and the overall pro-inflammatory burden (Wiley et al., 2018). Indirect suggestions that SARS-CoV-2 may impact the MDM2/p53 regulatory loop comes from the evidence that similarly to SARS-CoV and MERS-CoV (Chen and Subbarao, 2007; Yuan et al., 2015), the new coronavirus induces low type I IFNs levels, most likely contributing to slow-down the immune response in COVID-19 patients (Li et al., 2020). Idasanutlin is usually a second-generation potent and selective small-molecule MDM2 antagonist with a pyrrolidine structure (Ding et al., 2013). Idasanutlin shows an identical cellular mechanism to other Nutlin family molecules, which our group of investigators has intensively analyzed over more than a decade both in and models as non-genotoxic activators of p53 (Tisato et al., 2017). Compared to first-generation Nutlin, second-generation Idasanutlin showed enhanced potency, selectivity, and bioavailability (Ding et al., 2013). In a multicenter clinical study of phase I/Ib, administration of Idasanutlin at doses 400C1600 mg/d for 5?d to AML patients showed acceptable security, supporting its clinical evaluation as monotherapy and in combination with anti-leukemic drugs (Montesinos et al., 2020). In another recent study on policytemia vera, patients were treated with Idasanutlin (doses: 100 and 150 mg/d respectively) following a routine of treatments of 5 consecutive days of a 28-d cycle (Mascarenhas et al., 2019), and Idasanutlin was well tolerated. Overall, the study did not show dose-limiting toxicity, although low-grade gastrointestinal toxicity was generally detected (Mascarenhas et al., 2019). Of notice, a recent review confirmed that Idasanutlin is usually well tolerated (Khurana and Shafer, 2019). With regard to common unfavorable side effects due to Idasanutlin treatment, the reported studies were restricted to diarrhea, nausea/vomiting and in some cases myelosuppression causing febrile neutropenia and thrombocytopenia (Siu et al., 2014), thought considered to be the effect of the drug on the normal cells (Tisato et al., 2017). On these bases, we believe that Idasanutlin represents an important candidate molecule to counteract SARS-CoV-2 pneumonia (Physique 1) and it should be tested in clinical trials in symptomatic COVID-19 patients. Open in a separate window Physique 1 Schematic representation the potential role of Idasanutlin to restore functional p53 antiviral activity.

Idasanutlin is certainly a second-generation powerful and selective small-molecule MDM2 antagonist using a pyrrolidine framework (Ding et al., 2013). Idasanutlin displays an identical mobile mechanism to various other Nutlin family substances, which our band of researchers has intensively researched over greater than a 10 years both in and versions as non-genotoxic activators of p53 (Tisato et al., 2017). In comparison to first-generation Nutlin, second-generation Idasanutlin demonstrated enhanced strength, selectivity, and bioavailability (Ding et al., 2013).

General, the study didn’t present dose-limiting toxicity, although low-grade gastrointestinal toxicity was frequently discovered (Mascarenhas et al., 2019). Of take note, a recently available review verified that Idasanutlin is certainly well tolerated (Khurana and Shafer, 2019). In regards to to common harmful side effects because of Idasanutlin treatment, the reported research were limited to diarrhea, nausea/throwing up and perhaps myelosuppression leading to febrile neutropenia and thrombocytopenia (Siu et al., 2014), idea regarded as the effect from the medication on the standard cells (Tisato et al., 2017).
