Clinical monograph: salacia

Salacia is a genus of flowering plants in the family Celastraceae, commonly known for its use in traditional medicine, particularly in Ayurvedic practices. Various species of Salacia have been studied for their potential anti-diabetic effects, primarily attributed to their ability to inhibit carbohydrate digestion and absorption. Salacia extracts are often utilized for their purported health benefits, including blood sugar regulation and weight management.

Indications

  • Type 2 diabetes mellitus
  • Impaired glucose tolerance
  • Weight management
  • Dyslipidemia

Dosage

Children: Refer to specific product guidelines or consult a healthcare professional for appropriate dosing.

Adults: Refer to specific product guidelines or consult a healthcare professional for appropriate dosing.

Mechanism of action

The primary mechanism of action for Salacia involves the inhibition of enzymes such as alpha-glucosidase and pancreatic alpha-amylase. By inhibiting these enzymes, Salacia reduces the breakdown of carbohydrates into glucose, thereby decreasing postprandial blood glucose levels. Additionally, it may enhance insulin sensitivity and modulate glucose transporters, contributing to improved glycemic control.

Pharmacodynamics

Salacia exhibits pharmacodynamic properties that include the modulation of glucose metabolism and insulin sensitivity. Its active components, such as salacinol and kotalanol, have been shown to exert significant effects on carbohydrate metabolism, leading to decreased absorption of sugars in the intestine and improved overall glycemic status. Furthermore, Salacia may also support weight management through its effects on fat metabolism and appetite regulation.

Pharmacokinetics

The pharmacokinetic profile of Salacia is not extensively studied; however, its active compounds are believed to be absorbed in the gastrointestinal tract and subsequently metabolized in the liver. The elimination half-life and specific metabolic pathways have yet to be clearly defined. Given its natural origin, variability in bioavailability may occur based on individual metabolism and other factors.

Molecular reference: curcuma

PubChem CID 969516

Molecular formula: C21H20O6

Mechanism of action

Curcumin acts as a scavenger of oxygen species, such as hydroxyl radical, superoxide anion, and singlet oxygen and inhibit lipid peroxidation as well as peroxide-induced DNA damage. Curcumin mediates potent anti-inflammatory agent and anti-carcinogenic actions via modulating various signalling molecules. It suppresses a number of key elements in cellular signal transduction pathways pertinent to growth, differentiation, and malignant transformation; it was demonstrated _in vitro_ that curcumin inhibits protein kinases, c-Jun/AP-1 activation, prostaglandin biosynthesis, and the activity and expression of the enzyme cyclooxygenase (COX)-2. Curcumin, a polyphenolic natural product, exhibits therapeutic activity against a number of diseases, attributed mainly to its chemical structure and unique physical, chemical, and biological properties. It is a diferuloyl methane molecule [1,7-bis (4-hydroxy-3- methoxyphenyl)-1,6-heptadiene-3,5-dione)] containing two ferulic acid residues joined by a methylene bridge. It has three important functionalities: an aromatic o-methoxy phenolic group, alpha, beta-unsaturated beta-diketo moiety and a seven carbon linker. Extensive research in the last two decades has provided evidence for the role of these different functional groups in its crucial biological activities. A few highlights of chemical structural features associated with the biological activity of curcumin are: The o-methoxyphenol group and methylenic hydrogen are responsible for the antioxidant activity of curcumin, and curcumin donates an electron/ hydrogen atom to reactive oxygen species. Curcumin interacts with a number of biomolecules through non-covalent and covalent binding. The hydrogen bonding and hydrophobicity of curcumin, arising from the aromatic and tautomeric structures along with the flexibility of the linker group are responsible for the non-covalent interactions. The alpha, beta-unsaturated beta-diketone moiety covalently interacts with protein thiols, through Michael reaction. The beta-diketo group forms chelates with transition metals, thereby reducing the metal induced toxicity and some of the metal complexes exhibit improved antioxidant activity as enzyme mimics. New analogues with improved activity are being developed with modifications on specific functional groups of curcumin... The present study demonstrates that curcumin acts as pro-oxidant and sensitizes human lung adenocarcinoma epithelial cells (A549) to apoptosis via intracellular redox status mediated pathway. Results indicated that curcumin induced cell toxicity (light microscopy and MTT assay) and apoptosis (AnnexinV-FITC/PI labeling and caspase-3 activity) in these cells. These events seem to be mediated through generation of reactive oxygen species (ROS) and superoxide radicals (SOR) and enhanced levels of lipid peroxidation. These changes were accompanied by increase in oxidized glutathione (GSSG), reduced glutathione (GSH) and gamma-glutamylcysteine synthetase (gamma-GCS) activity, but decrease in GSH/GSSG ratio. The induction of apoptosis and decrease in GSH/GSSG ratio was also accompanied by sustained phosphorylation and activation of p38 mitogen activated protein kinase (MAPK). On the other hand, addition of N-acetyl cysteine (NAC), an antioxidant, blocked the curcumin-induced ROS production and rescued malignant cells from curcumin-induced apoptosis through caspase-3 deactivation. However, L-buthionine sulfoximine (BSO), a GSH synthesis blocking agent, further enhanced curcumin-induced ROS production and apoptosis in A549 cells. Decreased GSH/GSSG ratio seems to be a crucial factor for the activation of MAPK signaling cascade by curcumin. The study therefore, provides an insight into the molecular mechanism involved in sensitization of lung adenocarcinoma cells to apoptosis by curcumin. Curcumin has many pharmaceutical applications, many of which arise from its potent antioxidant properties. The present research examined the antioxidant activiti

Pharmacodynamics

Intravenous application of 25 mg/kg bw curcumin to rats resulted in an increase in bile flow by 80 and 120%. In the rat model of inflammation, curcumin was shown to inhibit edema formation. In nude mouse that had been injected subcutaneously with prostate cancer cells, administration of curcumin caused a marked decrease in the extent of cell proliferation, a significant increase of apoptosis and micro-vessel density. Curcumin may exert choleretic effects by increasing biliary excretion of bile salts, cholesterol, and bilirubin, as well as increasing bile solubility. Curcumin inhibited arachidonic acid-induced platelet aggregation _in vitro_.
