    摘要: A novel nucleic acid derivative represented by the following general formula (I) and physiologically acceptable salt thereof which are expected to have an antiviral activity:
    wherein B represents a nucleic acid base derivative; A 1 and A 2 represent, independently of each other, OR 1 or OCOR 1 ; R 1 represents a hydrogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group; ℓ represents a number of 0 or 1; and m and n each represents an integer of 0-2; provided that when ℓ and m are 0, n is 0 or 2.

    摘要: It was found that 2-halogeno-oxetanocin A and 4'-phosphate thereof represented by the following general formula (1):

    wherein X represents a halogen atom and R represents a hydrogen atom or a phosphoric acid residue

    or salts thereof exhibit a strong antiviral activity and are useful as an active ingredient of therapeutic drug for viral diseases. Further, it was also found that the compounds of this invention are characterized in that they are not inactivated by adenosine deaminase widely present in living bodies and exhibit a high residual activity.
