Selinexor (Xpovio, KPT330) |
T290 |
32-128 |
Sentence |
denotes |
Selinexor is bis(trifluoromethyl)phenyl-triazole-based antineoplastic small molecule (Figure 7). |
T291 |
129-170 |
Sentence |
denotes |
It was first approved in 2019 by the U.S. |
T292 |
171-262 |
Sentence |
denotes |
FDA and is being prescribed with dexamethasone for refractory or relapsed multiple myeloma. |
T293 |
263-404 |
Sentence |
denotes |
Selinexor is an orally bioavailable, selective inhibitor of chromosome region maintenance 1 (CRM1) protein (also known as exportin 1 (XPO1)). |
T294 |
405-531 |
Sentence |
denotes |
CRM1 is the main export factor that shuttles nuclear proteins to the cytoplasm and is typically overexpressed in cancer cells. |
T295 |
532-656 |
Sentence |
denotes |
Its selective inhibition can assist in restoring the endogenous tumor-suppressing processes so as to eliminate cancer cells. |
T296 |
657-940 |
Sentence |
denotes |
Specifically, selinexor selectively and irreversibly modifies the essential Cys528 residue in CRM1, and thus, it blocks CRM1-mediated nuclear export of cargo proteins such as tumor suppressor proteins (p21, p53, pRB, BRCA1/2, FOXO, and others) from the cell nucleus to the cytoplasm. |
T297 |
941-1016 |
Sentence |
denotes |
This leads to the accumulation of tumor suppressor proteins in the nucleus. |
T298 |
1017-1168 |
Sentence |
denotes |
It also results in decreased levels of oncoproteins, cell cycle arrest, and apoptosis of cancer cells without affecting the normal cells [119,120,121]. |
T299 |
1169-1419 |
Sentence |
denotes |
Considering the current viral pandemic, CRM1 has been put forward as a facilitator of the export of viral proteins from the nucleus of the host cell to the cytoplasm as well as an amplifier of the activities of pro-inflammatory transcription factors. |
T300 |
1420-1524 |
Sentence |
denotes |
Thus, the CRM1 inhibitor selinexor may exert relevant antiviral and anti-inflammatory effects [122,123]. |
T301 |
1525-1693 |
Sentence |
denotes |
In fact, CRM1 inhibitors have exhibited activity against >20 different viruses, including RNA viruses such as respiratory syncytial virus and influenza virus [122,123]. |
T302 |
1694-1821 |
Sentence |
denotes |
Furthermore, CRM1 inhibition has also been identified in in vitro assays to have a potential activity against SARS-CoV-2 [124]. |
T303 |
1822-1942 |
Sentence |
denotes |
CRM1 was found to contribute to exporting several SARS-CoV proteins, such as S, N, 9b, Orf3 and Orf6 out of the nucleus. |
T304 |
1943-2029 |
Sentence |
denotes |
Thus, CRM1 inhibition is expected to inhibit the viral assembly [125,126,127,128,129]. |
T305 |
2030-2211 |
Sentence |
denotes |
Moreover, CRM1 has also been found to contribute to the nuclear export and functional inactivation of antioxidant, anti-inflammatory, and cytoprotective transcription factors [130]. |
T306 |
2212-2354 |
Sentence |
denotes |
High levels of CRM1 are found in multiple inflammatory conditions and may magnify inflammatory responses leading to severe organ damage [131]. |
T307 |
2355-2565 |
Sentence |
denotes |
In this direction, selinexor and similar inhibitors have exhibited potent anti-inflammatory activity by suppressing the activation of NFkB and p38 signaling, leading to reduced cytokines in a variety of models. |
T308 |
2566-2673 |
Sentence |
denotes |
For example, in a mouse model of sepsis, selinexor increased survival following a lethal dose of endotoxin. |
T309 |
2674-2859 |
Sentence |
denotes |
Selinexor reduced the inflammatory cytokine secretion of IL-6, TNF-α, and HMGB1 while reducing the numbers of macrophage and polymorphonuclear neutrophils in the mice peritoneal cavity. |
T310 |
2860-2985 |
Sentence |
denotes |
Selinexor also mitigated lipopolysaccharide-induced lung injury that is similar to acute respiratory distress syndrome [132]. |
T311 |
2986-3101 |
Sentence |
denotes |
Currently, selinexor is being evaluated in at least two phase 2 randomized trials in the U.S. in COVID-19 patients. |
T312 |
3102-3534 |
Sentence |
denotes |
One is to evaluate the activity, safety and reduction in mortality of two regimens of low-dose selinexor in patients with moderate or severe COVID-19 (NCT04355676, n = 80) and the other is to evaluate the activity of low-dose selinexor and its effect on the clinical recovery, viral load, length of hospitalization, and rate of morbidity and mortality in participants with severe COVID-19 compared to placebo (NCT04349098, n = 230). |
