Anti-viral compounds with low cytotoxicity are identified from screening of products found in Red Sea sponges, including the sponge Stylissa carteri. The identified compounds can be brominated pyrrole-2-aminoimidazole alkaloids and derivatives thereof. Specific examples of identified compounds include oroidin, hymenialdisine, and debromohymenialdisine, as well as derivatives thereof. The compounds also can be useful scaffolds or pharmacores for further chemical modification and derivatization. Selected compounds, particularly oroidin, show selective anti-viral HIV-1 activity coupled with reduced cytotoxicity. The compounds can function as HIV reverse-transcriptase inhibitors, and molecular modeling can be used to confirm inhibition.
通过对红海海绵(包括 Stylissa carteri 海绵)中发现的产品进行筛选,确定了具有低细胞毒性的抗病毒化合物。鉴定出的化合物可以是
溴化
吡咯-
2-氨基咪唑生物碱及其衍
生物。已鉴定化合物的具体例子包括oidin、hymenialdisine 和 debromohymenialdisine 及其衍
生物。这些化合物还可以作为有用的支架或药剂,用于进一步的
化学修饰和衍生化。某些化合物,特别是roidin,具有选择性抗 HIV-1 病毒活性,同时细胞毒性降低。这些化合物可作为 HIV 逆转录酶
抑制剂,分子模型可用于确认抑制作用。
