Doxofylline (Doxophylline) is a methylxanthine derivative with the presence of a dioxolane group in position 7. As a drug used in the treatment of asthma, doxofylline has shown similar efficacy to theophylline but with significantly fewer side effects in animal and human studies.

L-Theanine is a relaxing and nondietary amino acid found pretty much exclusively in teas from Camellia sinensis and is known to promote relaxation without sedation.

Diphylline (Diprophylline) is a xanthine derivative. Diphylline exerts bronchodilator effects and to a lesser extent vasodilator and diuretic properties. Diphylline probably acts as a competitive inhibitor of phosphodiesterase which leads to an increase in intracellular cAMP. This results in relaxation of bronchial smooth muscle and other smooth muscles. Diphylline may also antagonize adenosinereceptors. Diphylline is used in the treatment of acute bronchial asthma, chronic bronchitis and emphysema.

Theaflavin is a polyphenolic flavonoid that has been found in black tea and has diverse biological activities, including antioxidant, anticancer, anti-inflammatory, and antiviral properties

5-Galloylquinic acid as an index for the baking intensity of oolong teas. It has antioxidant activity.

Plantanone C exhibited moderate antioxidant activity against DPPH radical scavenging activity,with an IC50 value of 240. 2 μmol·L~(-1).

cis-3-Hexenyl hexanoate is an active compound. cis-3-Hexenyl hexanoate ester can be isolated from yellow-flowered delphinium and is also present in some fruits, where it has a strong fruity flavor.

3-Epicabraleadiol is a natural product of Camellia, Theaceae. The catalog number is TN2925 and the CAS number is 19942-04-2. 3-Epicabraleadiol can be used as a reference standard.

1. Theaflavine-3,3'-digallate (theaflavin digallate) and lactic acid together could reduce herpes simplex virus transmission.

Theaflavin-3'-Gallate (Theaflavin 2B) usually comes from the leaves of Camellia sinensis (L.) O. Kuntze. Theaflavin-3'-gallate, act as prooxidants and induce oxidative stress, with carcinoma cells more sensitive than normal fibroblasts.

Tetramethylkaempferol is a PPARγ agonist, it can improve insulin sensitivity by increasing the levels of adiponectin, an important adipocytokine associated with insulin sensitivity in adipose tissue. Tetramethylkaempferol can concentration-dependently enh

5,7,3',4'-Tetramethoxyflavone (TMF), a prominent polymethoxyflavone (PMF) derived from M. exotica, displays a range of notable bioactivities. These include anti-malarial, anti-fungal, anti-mycobacterial, and anti-inflammatory properties. Moreover, TMF specifically targets β-catenin signaling to exhibit chondroprotective activity.

4-Galloylquinic acid shows some antioxidative activity.

Acefylline (Theophylline-7-acetic acid), a stimulant drug of the xanthine chemical class, acts as an adenosine receptor antagonist. It is combined with diphenhydramine in the pharmaceutical preparation Etanautine to help offset its stimulant effects

Camelliaside B possesses deglycosylation activity.

Aminophylline (Phyllocontin) is a competitive nonselective phosphodiesterase inhibitor giving a bronchodilatory effect.

4-(2,6,6-Trimethyl-1-cyclohexenyl)-3-buten-2-one is a natural product for research related to life sciences. The catalog number is TN2999 and the CAS number is 79-77-6.

Camelliaside A is a compound with the anti-inflammatory effect.

Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. Theophylline inhibits the 3', 5'-CYCLIC NUCLEOTIDE PHOSPHODIESTERASE that degrades CYCLIC AMP thus potentiates the actions of agents that act through ADENYLYL CYCLASES and cyclic AMP.
