Aphidicolin inhibits adenovirus DNA replication in HeLa cells and in a cell-free, infected, nuclear extract in which viral DNA is elongated. The compound inhibits alpha DNA polymerase, extensively purified from HeLa cells, but has little or no effect on the beta or gamma DNA polymerases similarly purified. Aphidicolin does not affect thymidine uptake by cells nor does synthesis as it also inhibits DNA replication in uninfected cells. The inhibition by aphidicolin is reversible if the drug is removed within 18 hrs after addition to HeLa or Chinese Hamster Ovary cells but the cells are irreversibly affected if the drug remains for 48 hours.
阿非科林可抑制腺病毒在HeLa细胞以及一种无细胞、受感染的核提取物中的DNA复制,在该核提取物中病毒DNA会发生延长。该化合物可抑制从HeLa细胞中大量纯化得到的α-DNA聚合酶,但对同样纯化得到的β或γ-DNA聚合酶几乎没有影响。阿非科林不影响细胞对胸苷的摄取,也不影响其合成,因为它也会抑制未感染细胞中的DNA复制。如果在向HeLa细胞或中国仓鼠卵巢细胞中添加阿非科林后的18小时内将药物去除,其抑制作用是可逆的,但如果药物作用48小时,细胞就会受到不可逆的影响。
