Eupatolide is isolated from the flowers of Inula japonica with anti-inflammatory activity. Eupatolide can be used in studies about TRAIL resistance in breast cancer cells.

D-I03 is a selective RAD52 inhibitor with a Kd of 25.8 µM. D-I03 specifically inhibits RAD52-dependent single-chain annealing (SSA) and D-loop formation, with IC50 of 5 µM and 8 µM, respectively. D-I03 inhibited the growth of BRCA1 and BRCA2 deficient cells and inhibited the formation of damage-induced RAD52 foci, but does not effect on RAD51 foci induced by Cisplatin.

Communic acid has antibacterial activity, including against mycobacterial. trans-Communic acid has potential to be utilized as anti-wrinkling agents and cosmetic ingredients, as they suppress UVB-induced MMP-1 expression.

Nolatrexed dihydrochloride (Thymitaq) is the dihydrochloride salt of nolatrexed, a water-soluble lipophilic quinazoline folate analog with antineoplastic activity. Nolatrexed occupies the folate binding site of thymidylate synthase, resulting in inhibition of thymidylate synthase activity and thymine nucleotide synthesis with subsequent inhibition of DNA replication, DNA damage, S-phase cell cycle arrest, and caspase-dependent apoptosis. This agent also exhibits radiosensitizing activity.

Procarbazine hydrochloride (NSC-77213 HCl) is the hydrochloride salt of a methylhydrazine derivative with antineoplastic and mutagenic activities. Although the exact mode of cytotoxicity has not been elucidated, procarbazine, after metabolic activation, appears to inhibit the trans-methylation of methionine into transfer RNA (t-RNA), thereby preventing protein synthesis and consequently DNA and RNA synthesis. This agent may also undergo auto-oxidation, resulting in the formation of cytotoxic free radicals which damage DNA through an alkylation reaction.
