INTRODUCTION Indonesia is one of the countries with a tropical climate, where the air temperature tends to be humid and causes various viruses and bacteria to multiply easily (Chen et al. , 2021. Saputra, 2. It is very important to maintain the body's immune resistance, and apart from that, it is always necessary to be aware of viruses or bacteria that might be able to attack the body. One way is to always consume foods that can be used as antibiotics, antibacterials, and antivirals (Kumar et al. , 2. These functions are not only found in supplements. Therefore, we must know what compounds are contained in supplements or food so that they can be used as antibiotics, antibacterials, or antivirals. The -farnesene compound is a compound that is often found in living things such as apples, pears, and several other fruits (Zhu et al. , 2. In addition, this compound is also found in several flowers, such as the fried plate flower and the frangipani flower. several studies, this compound was also found in beetles and some marine animals (Wang et al. Although it is still rare to know about this compound, it turns out that it has many functions that are very useful in life. This farnesene compound is usually separated from plants by steam distillation or extraction, and the result is essential oil. This essential oil, which contains farnesene compound with a pleasant smell, can be used as an antiviral, a fragrance, and so on (Lu & Qiao, 2020. Wang et al. , 2. So, it is very unfortunate if only a few people are familiar with this compound. Therefore, in this article, we will write a review of one of the functions of the -farnesene compound as an antiviral. This antivirus is always needed in life to protect the body from various viruses that may approach our bodies anytime and anywhere. With this Correspondance Address E-mail: deniainurrokhim@gmail.

RESULT AND DISCUSSION Compound Structure and Name The -farnesene, accompanied by the IUPAC name . 6E)3. 11-trimethyl-1. 10-dodecatriene (Figure Alpha forms in -farnesene compounds as four stereoisomers that differ about the geometry of two of the three internal double -farnesene compounds also belong to a class of organic compounds known as sesquiterpenoids, which are terpenes with three successive isoprene units. Figure 1 Structure of . 6E)-3. 11-trimethyl-1. 10-dodecatriene Utility Food additives . The compound -farnesene is a constituent of the natural coating of apples, pears, and several other fruits. This makes farnesene consumption of these foods (Du et al. , 2022. Ehlers et al. , 2. As we know, fruits that contain -farnesene compounds have a good So it can be concluded that besides being able to produce a fragrant smell, this compound can also be used as a food flavoring because it can create a delicious taste. Fragrance -farnesene compound is a terpene compound that has 3 isoprene. Terpene is a hydrocarbon compound that is produced by Isoprene is a compound consisting of 10 and 15 C atoms (Du et al. , 2. This isoprene compound has the characteristic of being able to give off a fragrant smell. For that reason, this - farnesene compound is widely used as an ingredient in giving fragrance to fragrances, essential oils, and several other fragrance products, such as perfume. Farnesene compounds, which are long chain hydrocarbon compounds (C15H. have many applications in lubricants, cosmetics, fragrances, and biogels (Schotte et al. , 2. Biofuel Farnesene compounds, which are longchain hydrocarbon compounds (C15H. , have many applications in lubricants, cosmetics, fragrances, and biogels (Grenz et al. , 2. optimizing its production, this farnesene compound will be chemically synthesized, then expressed in cyanobacteria so that farnesene is synthesized via the MEP pathway. Farnesene cyanobacterium, evaporated into the flask head chamber, and recovered by adsorption in the resin column. Manganite | Journal of Chemistry and Education. Vol 2 Issue . 24-29 A Ainaini Habibah et al. Pest Control In several journals, it is explained that, based on the results of research, it was found that pesticides were derived from natural ingredients and were more environmentally The pesticides come from lime, kecombrang, noni. Pontianak oranges, kaffir limes, grapefruits, and several other fruits. for its use, it utilizes the content of flavonoids, phenolic compounds, saponins, alkaloids, and terpenoids (Ningsih, et al. As already explained, the content of essential oils used as pesticides contains terpenoid compounds, one of which is an -farnesene compound. The same thing is explained in the explanation of the functions of basil and lime as insecticides. these plants, there are active compounds such as linalol, augenol, methyl cinnamate, -farnesene, yu-ocimene, and several other compounds (Islamy & Asngad. Antimicrobial In several recent reports, it was reported that -farnesene which is an acyclic sesquiterpene compound, has an antimicrobial Antimicrobials have the function of killing bacteria that can harm the body. For example, in the explanation of the essential oil of a plate of fried flowers. The essential oil of sunflower oil has the highest constituent components, namely linalool and (E,E) farnesene. This essential oil has antimicrobial activity against several bacteria, such as Escherichia coli. Candida albicans. Campylobacter jejuni. Listeria monocytogenes, and Staphylococcus aureus, and can inhibit several other pathogens. Antivirus The use of ginger as a family medicinal plant shows that ginger has biological activities, one of which is antiviral. Where many chemical compounds were found in ginger, one of which is a terpene compound. Some of the terpene components in ginger that are considered the main constituents of essential oils are yuseskuipellandrene, -farnesene, yu-bisabolene, and -curcumene compounds. This shows that the -farnesene compound has antiviral activity. Composition of essential oils . educing symptoms of Covid-. In a research journal by Joyce Kelly R. Silva, et al in 2020. Starting from the function of essential oils as antivirals. Kelly and several of her friends hypothesized that essential oils could be used to fight the Covid-19 virus. So, they conducted a study in which they explained that the main protease of SARS-CoV-2Mpro, is a cysteine protease, which is important for processing polyproteins translated from the Covid-19 virus RNA (Grenz et al. , 2. Examined in terms of essential oil content, the compound with the best docking normalization value was the farnesene hydrocarbon Where in the first place is (E) yufarnesene, and followed by (E,E) -farnesene. Characteristic The physical properties of alphafarnesene compounds are as follows in Table 1. Table 1 Physical Properties of Alpha-Farnesene Physical Form/Smell Colorless to Pale Yellow-Green Liquid with a Fruity Odor Boiling point Solubility Polarity Density Molecular mass Refractive index -farnesene belongs to a class of organic It is a terpene with three successive isoprene units. It has the physical properties of a colorless to pale green-yellow liquid with a fruity flavor because -farnesene is a constituent of the natural coating of apples, pears, and other fruits, as well as ginger (Zhang & Tiefenbacher, 2. The boiling point of farnesene is 260AC to 262AC, the molecular mass 260AC until 262AC 01053 mg/L Non polar 35, and it has a solubility of 0. 01053 mg/L, so that -farnesene is insoluble in water, slightly soluble in ethanol, and soluble in benzene (Chuang et al. , 2. The -farnesene compound is a nonpolar compound because the structure of the -farnesene compound consists of three bonds: carbon single bonds, carbon double bonds, and carbon bonds with hydrogen. The single bond between carbon and carbon is a nonpolar bond that cancels each other's dipole The double bond between carbon and Manganite | Journal of Chemistry and Education. Vol 2 Issue . 24-29 A Ainaini Habibah et al. carbon is also a nonpolar bond that cancels each other's dipole moment, the bond between carbon and hydrogen is a nonpolar covalent Therefore, the polarity of the -farnesene compound as a whole is a nonpolar compound because it consists of polar bonds that cancel each other's dipole moments. Reaction The reaction that occurs in this compound is a biochemical reaction. If the -farnesene compound is reacted with diphosphate it will produce fernyl diphosphate. The reaction between . 6E)--farnesene and diphosphate can be seen in Figure 2. Figure 2 Reaction between . 6E)-- Farnesene and Diphosphate Fernesene pyrophosphate through a biosynthetic process. The reaction between . 6E)--farnesene and pyrophosphate can be seen in Figure 3. Figure 3 Reaction between . 6E)-- Farnesene and Pyrophosphate This sesquiterpene synthesis can catalyze the production of (E,E)--farnesene which can be used for the storage of fruits. The catalytic process produced four isomers: (E,E)-farnesene, (Z,E)--farnesene, (E,Z)--farnesene, and (Z,Z)--farnesene (Chuang et al. , 2. The mixture of isomeric forms of farnesyl diphosphate can convert geranyl diphosphate to monoterpenes (E)--ocimene, linalol, and miricen. Activity of -Farnesene as an Antiviral in Reducing the Symptoms of Covid-19 The compounds contained in essential oils have been screened for 171 components against the SARS-CoV-2 protein using a molecular docking technique. Among the 171 compounds that were filtered, one of them contained -farnesene compounds. It is said that -farnesene shows better binding with SARSCoV-2 Mpro, which indicates that this essential oil component, when administered alone or in a mixture, can inhibit viral replication (Tan et al. Non-structural protein 15 (Nsp. , the endoribonuclease of SARS-CoV, is required for successful viral infection (Bhardwaj et al. -farnesene showed the best binding with Nsp15. RNA replication is catalyzed by RNA- dependent RNA polymerase (RdR. in viral RNA and is an important step in viral Thus, it becomes a viable target for antiviral chemotherapy. The SARS-CoV-2 Spike (S) protein helps viral cells attach to human cells by interacting with the angiotensin-converting enzyme 2 (ACE. protein present on the host cell, making this interface a promising target for preventing the binding of SARS-CoV-2 to the host cell (Suenaga-Hiromori et al. , 2022. Yu et al. The best binding to human angiotensinconverting enzyme 2 (ACE. was observed with -farnesene. In the case of the SARS-CoV-2 spike protein, relatively better binding was observed with -farnesene. Overall. Alpha-Farnesene exhibits better binding potential to target These phytochemicals are found in varying amounts in the essential oils of various plants that may be used to treat Covid-19, but better data from preclinical and clinical trials is CONCLUSION The -farnesene compound, which has the IUPAC name . 6E)-3. 11-trimethyl-1. 10dodecatriene, is a terpene compound with 3 This compound has uses as a food additive Manganite | Journal of Chemistry and Education.
