Baloxavir marboxil Chemical Properties,Usage,Production
Description
Baloxavir marboxil is an antiviral drug developed by Shionogi Co., a Japanese pharmaceutical company and Roche for the treatment of influenza A and influenza B infections. The drug was initially approved for use in Japan in February 2018 and approved by the FDA on October 24, 2018 for the treatment of acute uncomplicated influenza in patients 12 years of age and older who have been symptomatic for no more than 48 hours Label. Baloxavir marboxil, a cap-endonuclease inhibitor, has a unique mechanism of action when compared to the currently existing neuraminidase inhibitor drug class used to treat influenza infections.
Pharmacokinetics
Baloxavir marboxil is a selective inhibitor of influenza cap-dependent endonuclease which prevents polymerase function and therefore influenza virus mRNA replication 5, 3. It has shown therapeutic activity against influenza A and B virus infections, including strains resistant to current antiviral agents 1. This drug inhibits an enzyme required for viral replication, thus rapidly treating flu virus infection 5, Label and alleviating the symptoms associated with infection. A single dose of this agent was shown to be superior to placebo in relieving influenza symptoms and superior to both oseltamivir and placebo drug in virologic outcomes (marked by decreased viral load).
Uses
Baloxavir marboxil is an influenza medication, an antiviral,that is taken as a single dose tablet,by mouth, by individuals that are 12 years of age or older,that have presented symptoms of this infection for no more than 48 hours.The efficacy of baloxavir marboxil administered after 48 hours has not been tested.
Contraindications
Baloxavir marboxil should not be co-administered with dairy products, calcium-fortified beverages, or laxatives, antacids, or oral supplements containing calcium, iron, magnesium, selenium, aluminum or zinc.
Metabolism
Baloxavir marboxil is a prodrug that is converted by hydrolysis to baloxavir, the active form that exerts anti-influenza virus activity Label.
Uses
Baloxavir Marboxil is a prodrug of S-033447, which is an inhibitor of the cap-dependent endonuclease of influenza A and B viruses.
Preparation
The synthesis of baloxavir marboxil involved the following steps: The coupling of the 1-R and 2 fragments was carried out under dehydration conditions of 1-propanephosphonic anhydride (T3P) and methanesulfonic acid at 70 °C to obtain protected baloxavir 19. Compound 19 was then reacted with 0.6 equivalents of PhBr and K2CO3. Debenzylation was then carried out using LiCl in CH3CONMe2 to give baloxavir acid in 94% yield. In the final step for the preparation of the prodrug, baloxavir acid was reacted with chloromethyl methyl carbonate in dimethylacetamide in 93% yield to form baloxavir marboxyl.
The reaction mechanism for the final step for the synthesis of baloxavir marboxil(BXM).

Biological Activity
Baloxavir marboxil is a prodrug that is metabolised to the active form baloxavir acid also known as S-033447. S-033447 is a small molecule inhibitor of the cap-dependent endonuclease of influenza A and B viruses. It has shown nanomolar antiviral activity against influenza A and B viruses in vitro. In murine models of seasonal influenza and avian influenza A(H5N1) or A(H7N9), orally administered baloxavir showed a rapid reduction in pulmonary viral loads and decreased mortality. Baloxavir significantly reduced the time for alleviation of symptoms and reduced virus titres at 24 and 48 hours post-treatment at three different doses (10 mg, 20 mg and 40 mg) in a phase II study with patients experiencing uncomplicated influenza.
Mechanism of action
Baloxavir marboxil is an influenza therapeutic agent, specifically, an enzyme inhibitor targeting the influenza virus' cap-dependent endonuclease activity, one of the activities of the virus polymerase complex. In particular, it inhibits a process known as cap snatching, by which the virus derives short, capped primers from host cell RNA transcripts, which it then uses for polymerase-catalyzed synthesis of its needed viral mRNAs. A polymerase subunit binds to the host pre-mRNAs at their 5' caps, then the polymerase's endonuclease activity catalyzes its cleavage "after 10–13 nucleotides". As such, its mechanism is distinct from neuraminidase inhibitors such as oseltamivir and zanamivir.
Side effects
Common side effects following the single dose administration of baloxavir marboxil include diarrhea, bronchitis, common cold, headache, and nausea. Adverse events were reported in 21% of people who received baloxavir, 25% of those receiving placebo, and 25% of oseltamivir.
