Benzamide(苯甲酰胺), a derivative of benzoic acid, is an inhibitor of poly(ADP-ribose) polymerase with an IC50 of 3.3 μM.

5-methoxyflavone(5-甲氧基黄酮) is a novel DNA polymerase-beta inhibitor and neuroprotective agent against beta-amyloid toxicity.

Pixantrone(马来酸盐匹杉琼) is a novel aza-anthracenedione compound with antitumor activity. It is a weak topoisomerase II inhibitor and forms stable DNA adducts through alkylation with specificity for DNA hypermethylated sites.

Nimustine Hydrochloride(盐酸尼莫司汀) is the hydrochloride salt of nimustine, a nitrosourea with antineoplastic activity that alkylates and crosss DNA, thereby causing DNA fragmentation, inhibition of protein synthesis, and cell death.

Vidarabine monohydrate(阿糖腺苷一水合物) is a nucleoside antibiotic with antiviral acitivity that interferes with the synthesis of viral DNA. It is used to treat herpes simplex and varicella zoster viruses.

5'-Cytidylic acid(胞苷-5'磷酸) is a nucleotide that is used as a monomer in RNA.

Uridine-5'-triphosphate (UTP)(尿苷-5'-三磷酸三钠盐) is a pyrimidine nucleoside triphosphate and a substrate for the synthesis of RNA during tranion.

Rimantadine Hydrochloride(1-(1-金刚烷基)乙基胺盐酸盐) is an RNA synthesis inhibitor that is used as an antiviral agent in the prophylaxis and treatment of influenza. It works by inhibiting a viral protein called M2, which normally mediates the transport of acid ions across the influenza virion shell.
