(R)-Carvone123-triazoleClick chemistryDFT calculationMolecular dockingRegioselectivityIn the current study, natural (R)-carvone was used as starting material for the efficient synthesis of several 1,2,3-triazole derivatives. The produced products were obtained in good yields and characterized by 1H ...

2024In the present work, we describe the synthesis of new 1,3,4-thiadiazole derivatives from natural (R)-carvone in three steps including, dichloro-cyclopropanation, a condensation with thiosemicarbazide and then a 1,3-dipolar cycloaddition reaction with various nitrilimines. the targeted compounds ...
This can be easily illustrated by the different odors of the closely related monoter- penes (R)- and (S)-limonene and (R)- and (S)-carvone (9a,b and 10a,b; Figure 3), which result from the stereospecific interaction of these compounds with the olfactory G-protein- coupled receptors....
The odorants used were 3-mercapto-2-methylpentan-1-ol (#242803), 3-mercapothexyl acetate (#137912, Chemos GmbH, Regenstauf, Germany), 2-phenylethanethiol (#P1715, TCI Deutschland GmbH, Eschborn, Germany), allyl phenyl acetate (#W203904), and (R)-(-)-carvone (#124931, Sigma-Aldrich...
Diabetes is considered one of the five most severe diseases worldwide. The main symptoms of diabetes include increased blood glucose, excessive thirst, frequent urination, impaired vision, hyperphagia, weight loss, nausea, and vomiting [2,4]. Type 1 and Type 2 are the two most widespread forms...
Phytosterol extraction was conducted as previously described by [79] using 100 mg (dry weight) of tobacco BY-2 cells. Experiences were performed in triplicate, and sterols were quantified using α-cholestane as a standard and calculated as a percentage, taking the mean of total phytosterol content...
of theskin lipids(Chen et al 2013). Some components, such ascarvone, can also reverse the permeation enhancement effect so that vital skin barrier function is restored and not permanently changed after the application of dermal enhancers (Kang et al 2007; Aggarwal et al 2012). Some components...
(3H)-one each had two H-bond acceptors. In contrast, bigelovin, ethyl levulinate, and R-carvone had five, three, and one, respectively. Except for bigelovin, the LogP values of the ligands were less than 5.Table 7shows that the methyl nonanoate ester had the lowest LogS value ...
(−)-carvone-5,6-oxide, phthalic acid, and bis-7-methyloctyl ester showed a higher docking score than the standard Kojic acid. The results showed that 2-hydroxy-n-(2-phenylethyl) benzamide has the strongest binding affinity (−7.9 kcal/mol), which is two-thirds-times greater than the...
