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; A1 and A2 represent, independently of each other, OR1 or OCOR1; R1 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.
由以下通式(I)代表的新型核酸衍生物及其生理上可接受的盐,有望具有抗病毒活性:
其中 B 代表核酸碱基衍生物;A1 和 A2 各自代表 OR1 或 OCOR1;R1 代表氢原子、取代或未取代的烷基或取代或未取代的芳基;ℓ 代表 0 或 1 的数字;m 和 n 各自代表 0-2 的整数;但当 ℓ 和 m 为 0 时,n 为 0 或 2。
