Dinaline represents a group of pharmacologically active lipophilic substances with a relatively simple structure derived from N-acyl-o-phenylenediamine. It has been found to exhibit high antineoplastic activity in a series of slowly growing tumors such as chemically induced rat mammary and colorectal carcinomas, osteosarcoma C22LR and Brown Norway myeloid leukemia. The drug was inactive against many of the typically hypersensitive signal tumors, i.e. mouse leukemias P388 and L1210, sarcoma 180 and Yoshida sarcoma. Colon carcinoma cells exposed to dinaline demonstrate distinct but reversible changes in amino acid transport, protein metabolism, DNA synthesis and cell proliferation.

Methylparaben (E number E218) is preservative in the food, cosmetic, and pharmaceutical industries. It is completely absorbed through the skin or after ingestion and and it is hydrolyzed to para-hydroxybenzoic acid, and metabolites are rapidly excreted in the urine. Methylparaben is on the FDA generally regarded as safe list.

Niridazole is used (but not officially recommended) for the treatment of schistosomiasis, dracunculiasis and tungiasis. The mode of action of niridazole is not fully understood. The major action of niridazole seems to be on the glycogen metabolism of the helminths. The drug also case structural damage to the reproductive system of female schistosomes. Another possible mechanism of action of niridazole involves the inhibition of DNA synthesis in schistosomes. It is metabolized in the liver. The most serious side effects were those connected with the nervous area (convulsion, hallucination, etc.).
