(+)-Limonene
(+)-Limonene, also known as d-limonene, is a naturally occurring monoterpene which is the major component in orange oil. Currently, (+)-limonene is widely used as a flavour and fragrance and is listed to be generally recognized as safe in food by the Food and Drug Administration (21 CFR 182.60 in the Code of Federal Regulations, U.S.A.). Recently, however, (+)-limonene has been shown to cause a male rat-specific kidney toxicity referred to as hyaline droplet nephropathy. Furthermore, chronic exposure to (+)-limonene causes a significant incidence of renal tubular tumours exclusively in male rats. Although (+)-limonene is not carcinogenic in female rats or male and female mice given much higher dosages, the male rat-specific nephrocarcinogenicity of (+)-limonene may raise some concern regarding the safety of (+)-limonene for human consumption. A considerable body of scientific data has indicated that the renal toxicity of (+)-limonene results from the accumulation of a protein, alpha 2u-globulin, in male rat kidney proximal tubule lysosomes. This protein is synthesized exclusively by adult male rats. Other species, including humans, synthesize proteins that share significant homology with alpha 2u-globulin. However, none of these proteins, including the mouse equivalent of alpha 2u-globulin, can produce this toxicity, indicating a unique specificity for alpha 2u-globulin. With chronic exposure to (+)-limonene, the hyaline droplet nephropathy progresses and the kidney shows tubular cell necrosis, granular cast formation at the corticomedullary junction, and compensatory cell proliferation. Both (+)-limonene and cis-d-limonene-1,2-oxide (the major metabolite involved in this toxicity) are negative in vitro mutagenicity screens. Therefore, the toxicity-related renal cell proliferation is believed to be integrally involved in the carcinogenicity of (+)-limonene as persistent elevations in renal cell proliferation may increase fixation of spontaneously altered DNA or serve to promote spontaneously initiated cells. The scientific data demonstrates that the tumorigenic activity of (+)-limonene in male rats is not relevant to humans. The three major lines of evidence supporting the human safety of (+)-limonene are (1) the male rat specificity of the nephrotoxicity and carcinogenicity; (2) the pivotal role that alpha 2u-globulin plays in the toxicity, as evidenced by the complete lack of toxicity in other species despite the presence of structurally similar proteins; and (3) the lack of genotoxicity of both (+)-limonene and d-limonene-1,2-oxide, supporting the concept of a nongenotoxic mechanism, namely, sustained renal cell proliferation (PMID:2024047). (4r)-limonene, also known as (+)-4-isopropenyl-1-methylcyclohexene or (R)-1-methyl-4-(1-methylethenyl)cyclohexene, is a member of the class of compounds known as menthane monoterpenoids. Menthane monoterpenoids are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Thus, (4r)-limonene is considered to be an isoprenoid lipid molecule (4r)-limonene can be found in sweet marjoram, which makes (4r)-limonene a potential biomarker for the consumption of this food product (4r)-limonene can be found primarily in saliva.
(+)-Sabinene
Sabinene (CAS: 3387-41-5) belongs to the class of organic compounds known as bicyclic monoterpenoids. These are monoterpenoids containing exactly 2 rings, which are fused to each other. Thus, sabinene is considered to be an isoprenoid lipid molecule. Sabinene is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. (+)-Sabinene, also known as (+)-4(10)-thujene, is found in common sage and Myristica fragrans (nutmeg).
Sabinene
Sabinene is a thujene that is a bicyclic monoterpene isolated from the essential oils of various plant species. It has a role as a plant metabolite. Black pepper allergenic extract is used in allergenic testing. Laurus nobilis allergenic extract is used in allergenic testing. Nutmeg allergenic extract is used in allergenic testing. Sabinene is a natural product found in Teucrium montanum, Xylopia aromatica, and other organisms with data available. Carrot Seed Oil is the oil extracted from the seeds of Daucus carota. Carrot seed oil is primarily used in skin treatment preparations. A thujene that is a bicyclic monoterpene isolated from the essential oils of various plant species. 4(10)-thujene, also known as sabinen or 1-isopropyl-4-methylenebicyclo[3.1.0]hexane, is a member of the class of compounds known as bicyclic monoterpenoids. Bicyclic monoterpenoids are monoterpenoids containing exactly 2 rings, which are fused to each other. 4(10)-thujene is a citrus, pepper, and pine tasting compound and can be found in a number of food items such as sweet orange, green bell pepper, pot marjoram, and parsley, which makes 4(10)-thujene a potential biomarker for the consumption of these food products. Sabinene is an naturally occurring bicyclic monoterpene which can be used as flavorings, perfume additives, fine chemicals, and advanced biofuels. Sabinene is also an orally active compound to attenuates skeletal muscle atrophy and regulates ROS-mediated MAPK/MuRF-1 pathways[1][2].
