| 摘要 |
<p>The present invention relates to novel flavilium derivatives of general formula (I) wherein X is a non-toxic anion, R1 and R2 are independently selected from hydrogen or -OY group in which Y is hydrogen, α-amino-acyl group or amino-alkyl group of 1 to 5 carbon atoms; R5 is hydrogen, α-amino-acyl group or amino-alkyl group of 1 to 5 carbon atoms; R3, R4, and R7 independently are hydrogen or alkyl group of 1 to 5 carbon atoms, R6 is hydrogen, hydroxy group or alkyl group of 1 to 5 carbon atoms. The compounds of general formula (I) possess outstanding selective anti-viral effect.</p> |
