按照本发明的化合物还在慢病毒(lentivirus)感染的细胞培养中显示出作用。可以以HIV病毒为例来显示此作用。
在细胞培养中感染HIV
HIV试验按Pauwels等人的方法〔参见Joumal of VirologicalMethods 20,(1988),309-321〕进行,略有改动。
用Ficoll-Hypaque富集正常人血淋巴细胞(PBLs),并将其在RPMI1640和含植物凝集素(90μg/ml)和interleukin-2(40U/ml)的20%胎牛血清中刺激。为感染HIV,将PBLs制成粒状,然后将此细胞粒悬浮在1ml HIV病毒吸附溶液中,并于37℃培养1小时。
将此病毒吸附溶液离心,将感染的细胞粒吸收至生长培养基中使得其浓度达到1×105细胞/ml。将用此方法感染的细胞按1×104细胞/孔用移液管移至96孔微滴板的孔中。
该微滴板的第一纵列仅含生长培养基和未被感染的细胞,但却完全按上述方法进行了处理(细胞对照组)。微滴板的第二纵列在生长培养基中仅含有HIV感染的细胞(病毒对照组)。其它孔中含有不同浓度的本发明化合物,由微滴板的第3纵列的孔起,试验物质以2倍为一级被稀释210倍。
在未处理的病毒对照组中,将各试验组在37℃培养直至出现HIV的典型的合胞体生成(感染后3-6天之间),,然后用显微镜测定。在未处理的病毒对照组中,在这些试验条件下产生约20个合胞体,而未处理的细胞对照组未显示出合胞体。
以处理的和感染的细胞的浓度测定IC50值,在此值时,50%(约10个合胞体)的病毒诱发的合胞体被用本发明化合物处理所抑制。
现已发现,按照本发明的化合物能保护HIV感染的细胞免于病毒所致细胞破坏。
