  • Publication number: 20250129368
    Abstract: The present disclosure provides siRNA that suppresses proliferation of new coronaviruses (SARS-COV-2). The siRNA disclosed herein includes: a sense strand; and an antisense strand. The sense strand includes a target sequence comprising 19 to 23 bases in which a base at a 5? terminal is guanine (G) or cytosine (C), and an overhang comprising 2 to 4 bases added to a 3? terminal side of the target sequence. The antisense strand includes a sequence complementary to the target sequence, and an overhang comprising 2 to 4 bases added to a 3? terminal side of the complementary sequence. Here, at least a part of the target sequence contains at least a part of a base sequence encoding a signal peptide region of a spike protein (S protein) of SARS-COV-2.
