| | Emetine dihydrochloride Usage And Synthesis |
| Description | As the principal alkaloid of ipecac, Emetine dihydrochloride is derived from Uragoga ipecacuanha ground roots, which is used in the treatment of amebiasis. It can also be used as an emetic to induce vomiting.
Emetine dihydrochloride functions by inhibiting ribosome movement along mRNA, which results in irreversibly blocking protein synthesis in eukaryotic cells instead of prokaryotic cells. Besides, it has been proved that it can induce hypotension through blocking adrenoreceptors. | | References | https://www.scbt.com/scbt/product/emetine-dihydrochloride-316-42-7

https://pubchem.ncbi.nlm.nih.gov/compound/3068143#section=Top | | Chemical Properties | white powder or crystals | | Chemical Properties | Emetine dihydrochloride is a colorless, combustible powder which turns yellow on exposure to heat or
light. | | Uses | Anti-amebic. | | Uses | Emetine, an alkaloid from ipecac, C29H40O4N2, is a white powder with a very bitter taste. The substance is soluble in alcohol and ether, slightly soluble in water. Emetine darkens upon exposure to light. The compound is derived by extraction from the root of Cephalis ipecacuanha (ipecac). It is also made synthetically. Medically, ipecac is useful as an emetic (induces vomiting) for emergency use in the treatment of drug overdosage and in certain cases of poisoning. Ipecac should not be administered to persons in an unconscious state. It should be noted that emesis is not the proper treatment in all cases of potential poisoning. It should not be induced when such substances as petroleum distillates, strong alkali, acids, or strychnine are ingested. | | Uses | Emetine dihydrochloride has been used:
- as a protein synthesis inhibitor to study its effects on human papillomavirus type 8 E2 protein half-life
- to study its effects on the stress granules assembly
- as a chain-elongation inhibitor in puromycin assay for protein synthesis
| | Definition | ChEBI: Emetine dihydrochloride is the dihydrochloride salt of emetine. It has a role as an antiprotozoal drug, an antiviral agent, an antineoplastic agent, an antimalarial, an autophagy inhibitor, an emetic, a protein synthesis inhibitor and an anticoronaviral agent. It contains an emetine(2+). | | General Description | Clusters of needles after drying at 221°F. Turns yellow on exposure to light or heat. An injectable form of emetine, an anti amebic. Emetine is the active ingredient of ipecac. | | Air & Water Reactions | Water soluble. | | Reactivity Profile | When heated to decomposition, EMETINE DIHYDROCHLORIDE emits very toxic fumes of chlorides, hydrogen chloride and oxides of nitrogen. Turns yellow on exposure to light or heat [EPA, 1998]. | | Health Hazard | EMETINE DIHYDROCHLORIDE is highly toxic orally. It is an eye irritant. (Non-Specific -- Emetine) Emetine is classified as extremely toxic. Probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and one teaspoon for a 150-lb person. | | Fire Hazard | When heated to decomposition, EMETINE DIHYDROCHLORIDE emits very toxic fumes of chlorides, hydrogen chloride and oxides of nitrogen. Turns yellow on exposure to light or heat | | Biochem/physiol Actions | Emetine dihydrochloride is a member of the ipecac alkaloids family. It can mediate inhibition of protein and nucleic acid synthesis. It exhibits antiviral activity against dengue virus infection and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Emetine dihydrochloride exhibits anti-proliferative effects against bladder cancer cells. It also possesses anti-protozoal activity. | | Mechanism of action | Epinephrine, a hormone having a benzenoid structure, C9H13O3N, also called adrenaline. It can be obtained by extraction from the adrenal glands of cattle and also prepared synthetically. Its effect on body metabolism is pronounced, causing an increase in blood pressure and rate of heartbeat. Under normal conditions, its rate of release into the system is constant, but emotional stresses, such as fear or anger rapidly increase the output and result in temporarily heightened metabolic activity. Epinephrine is used for the symptomatic treatment of bronchial asthma and reversible bronchospasm associated with chronic bronchitis and emphysema. The drug acts on both alpha and beta receptor sites. Beta stimulation provides bronchodilator action by relaxing bronchial muscle. Alpha stimulation increases vital capacity by reducing congestion of the bronchial mucosa and by constricting pulmonary vessels.
Epinephrine has numerous effects on intermediary metabolism. Among these are promotion of hepatic glycogenolysis, inhibition of hepatic gluconeognesis, and inhibition of insulin release. The drug also promotes the release of free fatty acids from triglyceride stores in adipose tissues. Epinephrine produces numerous cardiovascular effects. Epinephrine is particularly useful in treating conditions of immediate hypersensitivity— interactions between antigen and antibody. These mechanisms cause attacks of anaphylaxis, hay fever, hives and allergic asthma. Anaphylaxis can occur after bee and wasp stings, venoms, etc. Although the mechanism is not fully understood, epinephrine can play a lifesaving role in the treatment of acute systemic anaphylaxis. | | Safety Profile | A poison by ingestion,
