Antitumor agent-38 is a highly effective antitumor compound that exhibits antiproliferative activity towards cancer cells. It induces cell cycle arrest specifically at the late S and G2/M phase, while not impeding microtubule formation or altering cell morphology [1].
Duocarmycin A, an antitumor antibiotic, is a DNA alkylator and efficiently alkylates adenine N3 at the 3′ end of AT-rich sequences in the DNA. Duocarmycin A, as a chemotherapeutic agent, results in HLC-2 cells typically apoptotic changes.
