Duocarmycin A 是众所周知的抗肿瘤抗生素之一,可有效地使 DNA 中富含 AT 的序列 3' 末端的腺嘌呤 N3 烷基化。Duocarmycin A 作为一种化学治疗剂,通常导致 HLC-2 细胞凋亡,包括染色质浓缩,DNA 直方图模式中的亚 G1 积累,以及procaspase-3 和 9 水平的降低。

Duocarmycin A, which is one of well-known antitumor antibiotics, efficiently alkylates adenine N3 at the 3′ end of AT-rich sequences in the DNA. Duocarmycin A, as a chemotherapeutic agent, results HLC-2 cells typically apoptotic changes, including chromatin condensation, sub-G1 accumulation in DNA histogram pattern, and decrease in procaspase-3 and 9 levels[1].
