  • Enzymes involved in catecholamine synthesis are present in the highest concentration in the adrenal medulla, however they were found also in other, mainly nervous tissues. Increased transcription of genes for catecholamine biosynthetic enzymes is an important mechanism to increase the capacity for epineprine/norepinephrine biosynthesis with stress. Gastrodia elata(Chinese name: Tienma), are very important Chinese herbal medicines used for the medical treatment of headaches, migraine, dizziness, epilepsy, rheumatism, neuralgia, paralysis and other neuralgic and nervous disorders. Immobilize stressed rat markedly increased tyrosine hydroxylase (TH) mRNA and dopamine-${\beta}$-hydroxylase (DBH) mRNA transcriptior level more than control group. But treated Gastrodia elata extracts in immobilized stressed rat slightly increased TH mRNA and DBH mRNA transcription level more than normal group. In addition, we are obtained identical results in PC12 cell line. Decrease of transcription level of TH mRNA and DBH mRNA is indicating that Gastrodia elata have a anti-stress effects which decrease the transcription level of TH and DBH mRNA on catecholamine biosynthesis pathway.

  • The methanol extract of Albizzia julibrissin Durazz. (Leguminosae) was successively partitioned into dichloromethane, ethylacetate, butanol (BuOH) and water fractions, and the effects of the each solvent extract on catecholamine biosynthesis in PC12 cells were investigated. Among them, the BuOH fraction $(5{\mu}g/ml\;medium)$ showed 68.8% and 63.6% inhibition on dopamine and norepinephrine content in PC12 cells, respectively. Tyrosine hydroxylase (TH) activity was also reduced markedly by treatment of the BuOH fraction (41.8% inhibition at $5{\mu}g/ml$ in the medium). Each solvent fraction did not show cytotoxicity towards PC12 cells by trypan blue exclusion test. This result suggests that the BuOH fraction has an inhibitory effect on catecholamine biosynthesis by reducing TH activity in PC12 cells.

  • Extracts of Black cohosh (Cimicifugae rhizoma) have been used for the treatment of climacteric complaints for decades. A significant number of woman entering menopause exhibit the following symptoms: getting hot flushes, night sweats, irritability, depression, and anxiety, A reduction of the frequency of hot flushes equivalents and hints on the antidepressant activity of Cimcifuga extracts. In the present work, we have screened several 80% ethanol extracts from medicinal plants and found that the extracts from Cimicifugae Rhizoma(Black cohosh:승마) have inhibitory effect on catecholamine secretion in bovine chromaffin cell. Since this extract inhibited 1,1-dimethyl-4-phenylpiperazinium iodide (DMPP)-induced catecholamine secretion, but did not inhibit KCl, bradykinin, and veratridine-evoked case, this inhibitory effect is mediated by nicotinic acetylcholine receptors with noncompetitive manner.

  • As a mussel-inspired surface independent modification chemistry using catecholamine family molecule was suggested on 2007, there are tremendous efforts being done by researchers from around the world to adjust and develop diverse applications using catecholamine family. Accordingly, we will discuss about the novel method to extend catecholamine applications, which is through the functional group substitution of catecholamine molecules.
