Diethyl 3,4-furandicarboxylate is a chemical compound that is used as an antiproliferative drug in cancer therapy. It is synthesized by the thermal isomerization of diethyl acetylenedicarboxylate. The product has been shown to inhibit the growth of human cancer cells and has antibacterial activity against Gram-positive bacteria. Diethyl 3,4-furandicarboxylate also inhibits the synthesis of DNA and RNA by binding to the enzyme ribonucleotide reductase. Its cytostatic effects are due to its ability to inhibit cellular proliferation by inhibiting protein synthesis.

Carbofuran is a broad-spectrum insecticide that belongs to the class of carbamates. It is used to control insects that damage crops and other plants. The mechanism of action for carbofuran involves inhibition of the sorbitol dehydrogenase enzyme, which blocks the conversion of glucose to sorbitol in insects, leading to their death. Carbofuran also has synergistic effects with nitrite ions. Carbofuran's chemical name is 3-methyl-2-(methylthio)propanal O-carbamate. It has been shown that carbofuron causes oxidative injury in mitochondria by inhibiting mitochondrial functions and energy metabolism, leading to its acute toxicities at high doses.

N-[(3S)-2,5-Dioxotetrahydro-3-furanyl]-2,2,2-trifluoroacetamide is a boronic acid that has been used to synthesize polymers. This compound is of interest for the synthesis of hydrophobic amino acids such as threonine and lysine. The high yield and functionalisation of this molecule make it deserving of further investigation.
