The authors used commercially available (1S)-(+)-camphor-10-sulfonic acid 125 (Figure 32), as a precursor for targeted monoterpene-based sulphonamides molecules 126128 (Figure 32). These results show that the presence of an unsaturated double bond is the main factor that determines the antioxidant activity of the investigated compounds (Figure 11) [40]. Some synthetic esters show good to excellent antifungal activity, especially with furan, thiophene, and pyridine unit. Furthermore, cells can adhere and grow on the surface of CP-TA composite coating as a result of the appropriate hydrophobicity provided by the chiral monoterpene moiety. Their biological activities are often much superior to the parent substances (monoterpenes); furthermore, they often exceed the commonly used standards in specialized areas of research. Biological activities such as antimicrobial, analgesic and anti-inflammatory are well-established for some of these . Monoterpenes are organic compounds that dictate the distinctive fragrance and flavor of the cannabis plant. Hence, works where the compounds containing those two structural elements are broadly tested and significant biological activity are demonstrated. The preliminary research indicates that the presence of the methyl group at the C-1 position and the substituted group at C-9 in the structure of these thymol derivatives seem to be essential for the inhibition of the proliferation of four cancer cell lines [46].

Obtaining new structures based on monoterpene compounds is a dynamically developing area, and one should expect new interesting biological applications, as well as modifications to structures that will improve current results in biological research. The borneol-based polymers are hydrophobic and noncytotoxic, which can significantly improve the cell adhesion ability [121,122]; on the other hand, borneol isomers on the material surface contribute to the surface bacterial resistance properties [119,120]. This is due to ozonolysis of monoterpenes like Limonene leading to the production of atmospheric SOA. [7], Many monoterpenes have unique smell and flavor. Monoterpene. Merriam-Webster.com Dictionary, Merriam-Webster, https://www.merriam-webster.com/dictionary/monoterpene. The meaning of MONOTERPENE is any of a class of terpenes C10H16 containing two isoprene units per molecule; also : a derivative of a monoterpene. One of the works on this subject is an article studying various heterocyclic ()-borneol derivatives with benzothiazole, benzoxazole, benzimidazole, and other heterocycles moieties (Figure 38) [105]. The obtained compounds were evaluated for their antitumor in vitro activities, and the results demonstrated that most target compounds showed potent antiproliferative activities against three human cancer cell lines. presented an interesting set of homochiral quaternary ammonium sulfonamides bearing hydrophobic camphor derived moieties [101]. Nowadays, it is obtained through distillation of camphor laurel tree wood (Cinnamomum camphora (L.) J.Presl) or otherwise by chemical transformation of other natural products, among other turpentines [86]. Terms & Conditions | Contact | Privacy Statement. [30] evaluated 1,2-dihydro-6-(4-hydroxy-5-isopropyl-2-methylphenyl)-2-oxo-4-arylpyridine-3-carbonitriles for their in vitro antioxidant and antimicrobial activity.
