Piperazine, a six membered nitrogen containing heterocycle, is of great significance to the rational design of drugs. This moiety can be found in a plethora of well-known drugs with various therapeutic uses, such as antipsychotic, antihistamine, antianginal, antidepressant, anticancer, antiviral, cardio protectors, anti-inflammatory, and imaging agents. Slight modification to the substitution pattern on the piperazine nucleus facilitates a recognizable difference in the medicinal potential of the resultant molecules. Piperazine has been used as an antihelmintic drug. Piperazine works by paralyzing the worms. They are then passed in the stool.

2-Hexenal belongs to the aldehyde and exists in two isomeric forms: cis (Z) and greater importance form, trans (E). Trans-2-hexenal was studied as a potential antifungal compound that can inhibits Aspergillus flavus Spore Germination. The inhibition takes place by the disruption of mitochondrial energy metabolism and the induction of early apoptosis. Besides, trans-2-hexenal can be an alternative fumigation agent for controlling M. incognita on tomato crops. Botanical nematicides have recently received increasing interest because of the high risks of some traditional nematicides to human health and the environment.

CTI-01 (ethyl pyruvate) is an investigational anti-inflammatory agent for the treatment of critical inflammatory conditions. CTI-01 was developed by Critical Therapeutics as a stable prodrug of pyruvate, a potent antioxidant, and a free radical scavenger. The drug showed an anti-inflammatory and tissue protection activity in animal models of pancreatitis, ischemia-reperfusion injury, sepsis, renal injury, and endotoxemia. CTI-01 was investigated in phase 2 clinical trials on patients undergoing cardiac surgery with cardiopulmonary bypass, but despite positive results in animal models, administration of EP does not appear to confer any benefit to cardiac surgical patients undergoing cardiopulmonary bypass. Besides clinical applications, ethyl pyruvate is long used as an additive to pharmaceutical preparations and foods, including candy, beverages, and baked goods. It is generally recognized as safe by the FDA.

Maleic acid monosodium salt. Used in water soluble polymers preparation.

Malic acid is a tart-tasting organic dicarboxylic acid that contributes to the taste of many sour or tart foods such as apples. Sodium Malate is the sodium salt of Malic Acid. Malic Acid and Sodium Malate can be found in a wide range of cosmetics and personal care products. Sodium Malate functions as a skin conditioning agent-humectant. As a food additive, Sodium Malate has the E number E350. Sodium Malate has demonstrated protective effect on cisplatin-induced toxicity in mice. Sodium malate could become a useful agent for the reduction of CDDP-induced toxicity, particularly nephrotoxicity and hepatotoxicity.
