Enzim RNA-bergantung RNA polimerase adalah sasaran dadah yang menarik untuk mengubati jangkitan denggi. Analog
nukleosida menyerupai substrat asal enzim polimerase. Ia bertindak sebagai perencat atau substrat kepada enzim ini lalu

proses replikasi virus. Kajian dok molekul untuk mengenal pasti interaksi molekular antara enzim dan ligannya telah

RdRp yang terdiri daripada sisa asid amino Asn492, Asn405, Lys401, Thr605 dan Gly601 telah dikenal pasti setelah
