Pharmacological Activities of Soursop ( Annona muricata Lin.)
Molecules 2022 Feb 10;27(4):1201.PMID:35208993DOI:10.3390/molecules27041201.
Soursop (Annona muricata Lin.) is a plant belonging to the Annonaceae family that has been widely used globally as a traditional medicine for many diseases. In this review, we discuss the traditional use, chemical content, and pharmacological activities of A.muricata. From 49 research articles that were obtained from 1981 to 2021, A.muricata's activities were shown to include anticancer (25%), antiulcer (17%), antidiabetic (14%), antiprotozoal (10%), antidiarrhea (8%), antibacterial (8%), antiviral (8%), antihypertensive (6%), and wound healing (4%). Several biological activities and the general mechanisms underlying the effects of A.muricata have been tested both in vitro and in vivo. A.muricata contains chemicals such as acetogenins (annomuricins and annonacin), alkaloids (coreximine and Reticuline), flavonoids (quercetin), and vitamins, which are predicted to be responsible for the biological activity of A.muricata.
Stereochemical inversion of (S)-reticuline by a cytochrome P450 fusion in opium poppy
Nat Chem Biol 2015 Sep;11(9):728-32.PMID:26147354DOI:10.1038/nchembio.1879.
The gateway to morphine biosynthesis in opium poppy (Papaver somniferum) is the stereochemical inversion of (S)-reticuline since the enzyme yielding the first committed intermediate salutaridine is specific for (R)-reticuline. A fusion between a cytochrome P450 (CYP) and an aldo-keto reductase (AKR) catalyzes the S-to-R epimerization of Reticuline via 1,2-dehydroreticuline. The Reticuline epimerase (REPI) fusion was detected in opium poppy and in Papaver bracteatum, which accumulates thebaine. In contrast, orthologs encoding independent CYP and AKR enzymes catalyzing the respective synthesis and reduction of 1,2-dehydroreticuline were isolated from Papaver rhoeas, which does not accumulate morphinan alkaloids. An ancestral relationship between these enzymes is supported by a conservation of introns in the gene fusions and independent orthologs. Suppression of REPI transcripts using virus-induced gene silencing in opium poppy reduced levels of (R)-reticuline and morphinan alkaloids and increased the overall abundance of (S)-reticuline and its O-methylated derivatives. Discovery of REPI completes the isolation of genes responsible for known steps of morphine biosynthesis.
Anti-Inflammatory Effects of Boldine and Reticuline Isolated from Litsea cubeba through JAK2/STAT3 and NF-κB Signaling Pathways
Planta Med 2018 Jan;84(1):20-25.PMID:28651290DOI:10.1055/s-0043-113447.
The anti-inflammatory effects of boldine and Reticuline isolated from Litsea cubeba were evaluated by using xylene-induced ear edema and carrageenan-induced paw edema in mice and rats. Our results demonstrated that intragastric administration with boldine and Reticuline significantly mitigated ear weight in mice and decreased paw volume in rats. A combination administration of boldine (0.5 mg/kg) + Reticuline (0.25 mg/kg) resulted in a potentiated inhibition in these two models. In parallel, boldine or Reticuline reduce the infiltration of neutrophil leukocytes in rat paw tissue, respectively, and the combination of the two groups performed a better anti-inflammatory activity as shown in histopathologies. Boldine, Reticuline, and their combination notably inhibited mRNA expressions of TNF-α, and IL-6 and reduced the phosphorylation levels of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3). Beyond that, their combination also can reduce the phosphorylation levels of p65 and IκBα in the pathological tissues of animals, as observed by real-time PCR and western blot analyses, respectively. These findings indicate for the first time that boldine and Reticuline have not only anti-inflammatory activity but also potential synergistic effects in vivo. The underlying mechanism may relate to the inhibition on the expression of pro-inflammatory cytokines, such as TNF-α and IL-6, which may be a consequence of JAK2/STAT3 and NF-κB pathway involvements. This study provides useful data for further exploration and application of boldine and Reticuline as potential anti-inflammatory medicines.
Cardiovascular effects induced by Reticuline in normotensive rats
Planta Med 2004 Apr;70(4):328-33.PMID:15095148DOI:10.1055/s-2004-818944.
The cardiovascular effects of Reticuline, isolated in a pure form from the stem of Ocotea duckei Vattimo, were studied in rats by using a combined in vivo and in vitro approach. In normotensive rats, Reticuline (5, 10 and 20 mg/kg, i. v., randomly) injections produced an intense hypotension. This hypotensive response was attenuated after either, L-NAME (20 mg/kg, i. v.), a nitric oxide (NO) synthase inhibitor, or atropine (2 mg/kg, i. v.), a muscarinic receptor antagonist. In isolated rat aortic rings with intact endothelium, Reticuline (3 x 10 ( - 6), 3 x 10 ( - 5), 3 x 10 ( - 4), 9 x 10 ( - 4) and 1.5 x 10 ( - 3) M) inhibited in a concentration-dependent manner the contractions induced by phenylephrine (1 microM), KCl (80 mM) and KCl (30 mM), [IC (50) = (0.4 +/- 0.1, 2.4 +/- 0.4 and 3 +/- 0.4) x 10 ( - 4) M, respectively). The effect of Reticuline on phenylephrine-induced contractions was attenuated by removal of the vascular endothelium [IC (50) = (2.5 +/- 0.7) x 10 ( - 4) M]. Similar results were obtained after pretreatment of the rings with L-NAME 100 microM [IC (50) = (1.3 +/- 0.1) x 10 ( - 4) M], L-NAME 300 microM [IC (50) = (3 +/- 0.3) x 10 ( - 4) M] or atropine 1 microM [IC (50) = (1.2 +/- 0.2) x 10 ( - 4) M]. On the other hand, the effect of Reticuline on phenylephrine-induced contractions was not affected by indomethacin 1 microM [IC (50) = (0.7 +/- 0.3) x 10 ( - 4) M]. Reticuline (3 x 10 ( - 6), 3 x 10 ( - 5), 3 x 10 ( - 4), 9 x 10 ( - 4) and 1.5 x 10 ( - 3) M) antagonized CaCl (2)-induced contractions, and also inhibited the intracellular calcium dependent transient contractions induced by norepinephrine (1 microM), but not those induced by caffeine (20 mM). These results suggest that the hypotensive effect of Reticuline is probably due to a peripheral vasodilation in consequence of: 1) muscarinic stimulation and NOS activation in the vascular endothelium, 2) voltage-dependent Ca (2+) channel blockade and/or 3) inhibition of Ca (2+) release from norepinephrine-sensitive intracellular stores.
Improvement of Reticuline productivity from dopamine by using engineered Escherichia coli
Biosci Biotechnol Biochem 2013;77(10):2166-8.PMID:24096658DOI:10.1271/bbb.130552.
Benzylisoquinoline alkaloids (BIAs) are pharmaceutically important compounds. We have previously devised a Reticuline (BIA) production method from dopamine by using Escherichia coli; however, its productivity was relatively low (33 µM, 11 mg/L). We report here, by fine-tuning the method, higher Reticuline productivity of 165 µM (54 mg/L), increasing the conversion efficiency by 8-fold. These results are important for developing an efficient route to fermentative Reticuline production.
