Zhao, Wei published the artcileRemote Stereocenter through Amide-Directed, Rhodium-Catalyzed Enantioselective Hydroboration of Unactivated Internal Alkenes, Application of cis-3,7-Dimethyl-2,6-Octadien-1-Ol, the publication is Journal of the American Chemical Society (2022), 144(29), 13071-13078, database is CAplus and MEDLINE.

Despite the frequent occurrence of γ-branched amines in bioactive mols., the direct catalytic asym. synthesis of this structural motif containing a remote stereocenter remains an important synthetic challenge. Here, authors report an amide-directed, rhodium-catalyzed highly diastereo- and enantioselective hydroboration of unactivated internal alkenes. This method provided facile access to enantioenriched amines containing β,γ-vicinal stereocenters. The application of this strategy to the synthesis of bioactive mols. was demonstrated. Computational studies indicated that migratory insertion of the alkene into rhodium hydride controls the enantioselectivity.

Prommaban, Adchara published the artcileMicroemulsion of essential oils from citrus peels and leaves with anti-aging, whitening, and irritation reducing capacity, SDS of cas: 106-25-2, the publication is Journal of Drug Delivery Science and Technology (2022), 103188, database is CAplus.

Although citrus essential oil is frequently used in cosmetics as fragrance, the biol. activities related to skin benefits have been rarely investigated. This study aimed to investigate the anti-skin aging and anti-melanogenic effects of citrus oils and develop microemulsion system to reduce the irritation capacity of citrus oils. Oils from leaves and fruit peels of Citrus aurantifolia (Christm.) Swing and Citrus reticulata Blanco cv.Shogun were from hydro-distillation Their chem. composition was analyzed using gas chromatog./mass spectrometry. Antioxidant activities were determined in terms of free radical scavenging activities, ferric reducing antioxidant power, and lipid peroxidation inhibition. Anti-aging and anti-melanogenic activities were investigated using related enzyme activity anal. Oils with the most potent biol. activities were selected for further incorporation into microemulsion. The irritation capacity of native and citrus microemulsion were investigated in human volunteers. Citrus oils comprised a range of chems., with limonene being a key component. All citrus oils demonstrated powerful antioxidative activities. C. reticulata dried peel oil significantly inhibited collagenase and tyrosinase activities, resulting in promising anti-aging and whitening properties. C. reticulata oil derived from dried peels (CR3) had a higher yield and more potent activity than the oils taken from fresh leaves and peels. Therefore, CR3 was developed into a microemulsion in which the internal droplet size was 266.5 ± 14.1 nm and the narrowest PDI of 0.396 ± 0.068. Microemulsion could significantly reduce the skin irritation property of CR3 in human volunteers. In conclusion, CR3 microemulsion was suggested as effective and safe for further cosmeceutical applications.

de Fatima Alves Nonato, Carla published the artcileComparative analysis of chemical profiles and antioxidant activities of essential oils obtained from species of Lippia L. by chemometrics, Quality Control of 106-25-2, the publication is Food Chemistry (2022), 132614, database is CAplus and MEDLINE.

Due to the importance of diseases associated with oxidative stress, the search for natural antioxidants proves to be essential. This work aimed to compare the chem. composition and antioxidant potential of essential oils from the genus Lippia L. through chemometric anal. The essential oils were characterized by gas chromatog. coupled with mass spectrometry. Antioxidant potentials were determined by DPPH, ABTS, Deoxyribose and β-carotene protection, Iron chelation and reduction methods. All data were related by multivariate analyzes. Essential oils showed low similar chem. compositions and no statistically significant relationship. These showed relevant antioxidant activity, especially for L. sidoides that obtained IC50 of 5.22 ± 0.08μg/mL in ABTS capture. Multivariate analyzes showed the effectiveness of L. alba compounds to DPPH scavenging, Fe3+ reduction and β-carotene protection, and L. gracilis components to deoxyribose protect. Thus, studies proving the antioxidant potential of Lippia compounds against oxidative stress and their use in food conservation are fundamental.

Santana, Alisson da Silva published the artcileSynergism between essential oils, promising alternative to control Sitophilus zeamais (Coleoptera: Curculionidae), Recommanded Product: cis-3,7-Dimethyl-2,6-Octadien-1-Ol, the publication is Crop Protection (2022), 105882, database is CAplus.

Combinations of essential oils (EOs) are promising alternatives for pest management in storage grains. A high diversity of compounds in EOs and EO mixtures can increase their toxicity. Addnl., EOs can be useful in insecticide resistance programs. For this reason, we evaluated the fumigant toxicity and repellent effects of six essential oils (Dysphania ambrosioides, DA; Pelargonium graveolens, PE; Piper arboreum, PA; Piper diospyrifolium, PD; Piper gaudichaudianum, PG; and Piper tuberculatum, PT) sep. and in binary combinations against adults of Sitophilus zeamais (the maize weevil). First, the insecticidal activity of all possible combinations of the six EOs were assessed. Next, the concentrations needed to cause 50% and 90% mortality (LC50 and LC90, resp.) in the S. zeamais population were determined for the most toxic EOs and mixtures After that, the synergistic effect of the mixtures was also verified. Finally, the most toxic treatments were assessed to determine the time required to cause mortality of 50% of the population and check the repellent effects on S. zeamais. The binary mixtures of DA and PE, PT, PG, PD, and PA were the most toxic against S. zeamais. The LC50 and LC90 values for these treatments ranged between 1.77 and 2.25μL L-1 and from 2.42 to 7.64μL L-1, resp. The mixtures were more toxic than the EOs tested sep., which indicates the occurrence of synergistic effects. All treatments caused mortality of 50% of the population of S. zeamais in less than 42 h of exposure. In addition, the combinations DA + PE, DA + PT, DA + PG, and DA + PA were repellent to S. zeamais. Based on these results, we conclude that the mixtures of EOs evaluated in this study are highly promising for the control of S. zeamais populations and can also be used for resistance management of this species.

Taktak, Nehad E. M. published the artcileNanoemulsions containing some plant essential oils as promising formulations against Culex pipiens (L.) larvae and their biochemical studies, Name: cis-3,7-Dimethyl-2,6-Octadien-1-Ol, the publication is Pesticide Biochemistry and Physiology (2022), 105151, database is CAplus and MEDLINE.

The chem. composition of cypress, lavender, lemon eucalyptus, and tea tree oils has been investigated using gas chromatog./mass spectrometry (GC/MS). These oils were tested for larvicidal activity against Culex pipiens alongside their nanoemulsions (NEs) and conventional emulsifiable concentrates (ECs). Oil-in-water (O/W) NEs preparation was based on a high-energy ultra-sonication technique. The effect of independent variables of preparation on the different outputs was studied using the response surface method to obtain the optimum preparation technique. The droplet sizes of prepared NEs were significantly different (71.67, 104.55, 211.07, and 70.67 for cypress, lavender, lemon eucalyptus, and Tea tree NEs, resp.). The zeta potentials of NEs were recorded to have a high neg. charge (-28.4, -22.2, -23.6, and – 22.3 mV for cypress, lavender, lemon eucalyptus, and tea tree NEs, resp.). The results showed that the tea tree oil has the most significant effect with LC50 = 60.02 and 57.10 mg/L after 24 and 48 h of exposure, resp. In comparison, cypress oil proved the lowest toxicity with LC50 values of 202.24 and 180.70 mg/L after 24 and 48 h, resp. However, lavender oil does not show any effect against larvae at tested concentrations In addition, pure oil exhibited the lowest larvicidal activity. However, the EC of all tested insecticides slightly improved the toxic action against the larvae. While the NEs showed significantly high toxicity compared to the EO and EC. An in vivo assessment of acetylcholine esterase (AChE), ATPase (ATPase), and gamma-aminobutyric acid transaminase (GABA-T) revealed that the NEs exhibited higher activity than the pure oils and ECs. This work describes these oils with potential use against C. pipiens larvae as eco-friendly products.

Luro, Francois published the artcilePhylogenetic and taxonomic status of Citrus halimii B.C. Stone determined by genotyping complemented by chemical analysis of leaf and fruit rind essential oils, Computed Properties of 106-25-2, the publication is Scientia Horticulturae (Amsterdam, Netherlands) (2022), 111018, database is CAplus.

Citrus phylogeny is currently based on genome anal. using mol. markers and sequencing. The 7 pure genetic groups that gave rise to all cultivated citrus underlie the diversity of citrus accessions originating from Asia. However, there are wild citrus forms whose phylogenetic position is unknown, such as mountain citron (Citrus halimii B.C. Stone) that was discovered in Malaysia in the early 1970s. We sought to elucidate its status by determining its genetic profile with 30 SSR and InDel markers distributed on the 9 chromosomes of the citrus reference genome as compared to those of the 7 pure genetic groups represented by 4 or 5 varieties each. The genetic study was supplemented by a comparison of the composition of essential oils obtained by fruit peel and leaf hydrodistillation to those of the citrus fruits used for genotyping. The genetic study demonstrated that C. halimii is not an interspecific hybrid (low heterozygosity) but rather a true species that shares a common ancestor with kumquats (Fortunella sp.), which would have evolved sep. The fruit aromatic profiles confirmed this kumquat/mountain citron relationship but also highlighted the uniqueness of C. halimii due to the presence of high proportions of compounds that have never been observed in other citrus fruits, such as germacrene D-8-one (accounting for 8.7% of the leaf essential oil).

Clery, Robin A. published the artcileChemical Diversity of Citrus Leaf Essential Oils, COA of Formula: C10H18O, the publication is Chemistry & Biodiversity (2022), 19(3), e202100963, database is CAplus and MEDLINE.

The essential oils from leaves of 20 com. citrus accessions maintained by the University of California, Riverside Givaudan Citrus Variety Collection and selected on the basis of their odor profile were analyzed by GCMS/FID. The main components were quantified while the semi-quant. percentage composition data was compiled with data from other publications for sample visualization, classification and comparison with leaf oils from other citrus accessions. Some compositional clusters aligned closely with the taxonomic clades of sweet orange, bitter orange, and C. hystrix while other clades like the mandarins and lemons showed distinct chem. sub-groups. Characteristic compounds for the clusters included linalyl acetate and linalool (bitter orange leaf), sabinene (sweet orange leaf), Me N-Me anthranilate (mandarin leaf), γ-terpinene (yuzu leaf), citronellal (C. hystrix), limonene, citronellal and citral (lemons and citrons). A chemometric approach combined with t-SNE cluster plots can be more informative than taxonomic assignments when considering flavor and fragrance characteristics.
