|| Reticuline is a key compound in the biosynthetic pathway for isoquinoline alkaloids in plants, which include morphine, codeine and berberine. Reticuline possesses potent central nervous system depressant action, it (50-100 mg/kg i.p.) can produce alteration of behaviour pattern, prolongation of pentobarbital-induced sleep, reduction in motor coordination and D-amphetamine-induced hypermotility and suppression of the conditioned avoidance response. (S)-Reticuline can elicit vasorelaxation probably due to the blockade of the L-type voltage-dependent Ca(2+) current in rat aorta, the effect may contribute to the potential cardioprotective efficacy of (S)-reticuline. |

|Knockdown of berberine bridge enzyme by RNAi accumulates (S)-reticuline and activates a silent pathway in cultured California poppy cells.[Pubmed: 17103244 ]|
|Reticuline is a key compound in the biosynthetic pathway for isoquinoline alkaloids in plants, which include morphine, codeine and berberine. |
METHODS AND RESULTS:
We established cultured California poppy (Eschscholzia californica) cells, in which berberine bridge enzyme (BBE) was knocked down by RNA interference, to accumulate the important key intermediate Reticuline. Both BBE mRNA accumulation and enzyme activity were effectively suppressed in transgenic cells. In these transgenic cells, end-products of isoquinoline alkaloid biosynthesis, such as sanguinarine, were considerably reduced and Reticuline was accumulated at a maximum level of 310 mug/g-fresh weight. In addition, 1 g-fresh weight of these cells secreted significant amounts of Reticuline into the medium, with a maximum level of 6 mg/20 mL culture medium. These cells also produced a methylated derivative of Reticuline, laudanine, which could scarcely be detected in control cells.
We discuss the potential application of RNAi technology in metabolic modification and the flexibility of plant secondary metabolism.

|In vivo and in vitro L-DOPA and reticuline exposure increases ganglionic morphine levels.[Pubmed: 15874894]|
|Given the presence of morphine, its metabolites and precursors, i.e., Reticuline, in mammalian and invertebrate tissues, it has become imperative to determine if exposing tissues to putative opiate alkaloid and dopamine precursors would result in increasing endogenous morphine levels.
METHODS AND RESULTS:
Endogenous morphine levels were determined by high performance liquid chromatography coupled to electrochemical detection and radioimmunoassay, following incubation of Mytilus edulis pedal ganglia with Reticuline or L-DOPA. Injection of L-DOPA or Reticuline into healthy animals was via the foot.
Ganglia incubated in vitro with Reticuline or L-DOPA for 1 hour exhibited a concentration and time dependent statistically significant increase in their endogenous morphine levels (5.0 +/- 0.47, 3.6 +/- 0.45 ng/ganglion, respectively). Injection of intact, healthy animals with Reticuline or L-DOPA also results in significantly higher endogenous ganglionic morphine levels.
METHODS AND RESULTS:
Taken together, we show that L-DOPA is being converted to morphine, demonstrating that pedal ganglia can synthesize morphine from these putative precursors in vitro and in vivo. This is the first demonstration of morphine being synthesized in a normal, healthy free living animal.

|Central depressant effects of reticuline extracted from Ocotea duckei in rats and mice.[Pubmed: 9720612]|
METHODS AND RESULTS:
Neuropharmacological studies were carried out with Reticuline, a benzylisoquinoline alkaloid, isolated from Ocotea duckei Vattimo. It was found that Reticuline (50-100 mg/kg i.p.) produced alteration of behaviour pattern, prolongation of pentobarbital-induced sleep, reduction in motor coordination and D-amphetamine-induced hypermotility and suppression of the conditioned avoidance response.
These observations suggest that Reticuline possesses potent central nervous system depressant action.

||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|(S)-reticuline induces vasorelaxation through the blockade of L-type Ca(2+) channels.[Pubmed: 18825370]|
|In Brazil, various species of the genus Ocotea are used in folk medicine for treating several diseases. The chemical characterization of this plant showed the presence of alkaloids belonging to the benzyltetrahydroisoquinoline family, the major component of which is (S)-Reticuline. |
METHODS AND RESULTS:
The present study investigated whether (S)-Reticuline exerts an inhibitory effect on smooth muscle L-type Ca(2+) channels. Tension measurements and patch clamp techniques were utilized to study the effects of (S)-Reticuline. Whole-cell Ca(2+) currents were measured using the A7r5 smooth muscle cell line. (S)-Reticuline antagonized CaCl(2)- and KCl-induced contractions and elicited vasorelaxation. It also reduced the voltage-activated peak amplitude of I (Ca,L) in a concentration-dependent manner. (S)-Reticuline did not change the characteristics of current density vs. voltage relationship. (S)-Reticuline shifted leftwards the steady-state inactivation curve of I (Ca,L). The application of dibutyryl cyclic adenosine monophosphate to the cell decreased the amplitude of Ca(2+) currents. In cells pretreated with forskolin, an adenylate cyclase activator, the addition of (S)-Reticuline caused further inhibition of the Ca(2+) currents suggesting an additive effect.
The results obtained show that (S)-Reticuline elicits vasorelaxation probably due to the blockade of the L-type voltage-dependent Ca(2+) current in rat aorta. The reported effect may contribute to the potential cardioprotective efficacy of (S)-Reticuline.
