Duocarmycin SA is an extremely potent cytotoxic agent and antitumor antibiotic that induces sequence-selective alkylation of duplex DNA, with an IC50 of 10 pM. It demonstrates synergistic cytotoxicity against glioblastoma multiforme (GBM) cells when combined with proton radiation in vitro.

NSC15520, a small-molecule inhibitor of Replication Protein A (RPA), selectively targets the N-terminal DNA binding domain (DBD) of RPA, preventing its interaction with p53 and RAD9. Additionally, NSC15520 impedes the helix destabilization of duplex DNA (dsDNA) oligonucleotides, playing a role in processes such as DNA replication, repair, recombination, and the DNA damage response signaling pathway [1].

Duocarmycin TM is a DNA alkylator. Duocarmycin TM is an exceptionally potent antitumor antibiotic.

Furamidine is also a selective and cell-permeable protein arginine methyltransferase 1 (PRMT1) inhibitor with an IC50 of 9.4 μM. Furamidine is selective for PRMT1 over PRMT5, PRMT6, and PRMT4 (CARM1) (IC50s of 166 μM, 283 μM, and >400 μM, respectively). Furamidine (DB75) is abisbenzamidine derivative and an antiparasite agent. Furamidine is a potent, reversible and competitive tyrosyl-DNA phosphodiesterase 1 (TDP-1) inhibitor. Inhibition of TDP-1 by Furamidine is effective both with single- and double-stranded DNA substrates but is slightly stronger with the duplex DNA.

Pentamidine is an antifungal and antiprotozoal agent, interacting directly with the pathogen genome by binding to AT-rich regions of duplex DNA and the minor groove of DNA, thereby interfering with DNA replication.
