在大动物(狗和灵长目动物)中全面观察每一种新的肿瘤-活性药物的临床前毒理太慢且花费太多,所需药物数量也较多。如果合成药物的得率低或天然产物提取困难,为了上述筛选试验而勉强制备大量极有可能被淘汰的药物则很不经济。为此,作者开展适用于 To comprehensively observe each new tumor in large animals (dogs and primates) - preclinical toxicology of the active drug is too slow and costly, requiring a large amount of medication. If the yield of synthetic drugs is low or the extraction of natural products is difficult, it would be uneconomical to barely prepare a large amount of drugs that are likely to be eliminated for the above screening tests. To this end, the author carries out
