Salicylic acid (2-Hydroxybenzoic acid), a natural compound extracted from Willow bark, is an anti-inflammatory inhibitor of activity cyclooxygenase.

Ferulic Acid (Coniferic acid) is a highly abundant phenolic phytochemical and a type of organic compound found in the Ferula assafoetida L. or Ligusticum chuanxiong.It can be absorbed by the small intestine and excreted through the urine.

Daidzein (Isoflavone) is an isoflavone extract from soy, which is an inactive analog of the tyrosine kinase inhibitor genistein. It has antioxidant and phytoestrogenic properties.

Guanidine hydrochloride (Aminoformamidine Hydrochloride) is a strong organic base existing primarily as guanidium ions at physiological pH. It is found in the urine as a normal product of protein metabolism. It is also used in laboratory research as a protein denaturant.

Naringin (Naringoside), a flavanone glycoside, exerts various of pharmacological effects such as blood lipid lowering, antioxidant activity, anticancer activity, and inhibition of cytochrome P450 enzymes.

Fumaric acid (2-Butenedioic acid) attenuates the eotaxin-1 expression in TNF-α-stimulated fibroblasts by suppressing p38 MAPK-dependent NF-κB signaling. Fumaric acid has recently been identified as an oncometabolite or an endogenous, cancer-causing metabolite. High levels of this organic acid can be found in tumors or biofluids surrounding tumors. Its oncogenic action appears due to its ability to inhibit prolyl hydroxylase-containing enzymes.

Stavudine (BMY-27857), a nucleoside reverse transcriptase inhibitor analog of thymidine, has activity against HIV.

Formamide (NSC-748) is a metabolite used for biological monitoring of workers exposed to N-N-dimethylformamide (DMF). There is a case of significant association between ever having been exposed to DMF and subsequent development of prostate cancer.
