Title:
RNA ACTION INHIBITOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/039598
Kind Code:
A1
Abstract:
Provided is a target RNA action inhibitor based on RNA interference and ASO. An RNA interference agent of the present invention is provided with a guide strand and a passenger strand against the target RNA, wherein blunt ends are formed at both ends of double stranded RNA obtained through pairing of the passenger strand and the guide strand, and one or more units selected from the group consisting of units represented by formula (1) and formula (2) are provided to: (a) the 5' end side and the 3' end side of the passenger strand; and (b) the 3' end side of the guide strand. Formula (1) (wherein X represents an oxygen atom or a sulfur atom). Formula (2) (wherein X represents an oxygen atom or a sulfur atom).
