Many viral and cellular mRNA species contain a leader sequence derived from a distant upstream site on the same gene by a process of RNA splicing. This process usually involves either nuclear functions or self-splicing of RNA molecules. Coronavirus, a cytoplasmic RNA virus, un- folds yet another mechanism of joining RNA, which involves the use of a free leader RNA molecule. This molecule is synthesized and dissociates from the template RNA, and subsequently re-associates with the template RNA at down- stream initiation sites of sub-genomic mRNAs to serve as the primer for transcription. This leader-primed transcriptional process thus generates viral mRNAs with a fused leader sequence. The purpose of the review to aggregate the anti-SARS drugs in the structural proteins from human SARS related coronavirus (SARS-CoV) while knowing little about the functional sites and possible mutations in these proteins. From a probabilistic viewpoint, we can theoretically select the amino acid pairs as potential candidates for anti-SARS drugs.
