Abstract
Duguetia pycnastera Sandwith (Annonaceae) is a tropical tree that can be found in the Guyanas, Bolivia, Venezuela, and Brazil. In Brazil, it is popularly known as “ata”, “envira”, “envira-preta”, and “envira-surucucu”. In the present work, we investigated the in vitro and in vivo HepG2 cell growth inhibition capacity of D. pycnastera leaf essential oil (EO). The chemical composition of the EO was determined by GC−MS and GC−FID analyses. The alamar blue assay was used to examine the in vitro cytotoxicity of EO in cancer cell lines and non-cancerous cells. In EO-treated HepG2 cells, DNA fragmentation was measured by flow cytometry. The in vivo antitumor activity of the EO was assessed in C.B-17 SCID mice xenografted with HepG2 cells treated with the EO at a dosage of 40 mg/kg. Chemical composition analysis displayed the sesquiterpenes α-gurjunene (26.83%), bicyclogermacrene (24.90%), germacrene D (15.35%), and spathulenol (12.97%) as the main EO constituents. The EO exhibited cytotoxicity, with IC50 values ranging from 3.28 to 39.39 μg/mL in the cancer cell lines SCC4 and CAL27, respectively. The cytotoxic activity of the EO in non-cancerous cells revealed IC50 values of 16.57, 21.28, and >50 μg/mL for MRC-5, PBMC, and BJ cells, respectively. An increase of the fragmented DNA content was observed in EO-treated HepG2 cells. In vivo, EO displayed tumor mass inhibition activity by 47.76%. These findings imply that D. pycnastera leaf EO may have anti-liver cancer properties.

Chemical Composition and Immunomodulatory Activity of Essential Oils from Rhododendron albiflorum. Molecules 2021; 26:molecules26123652. [PMID: 34203809 PMCID: PMC8232766 DOI: 10.3390/molecules26123652] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Revised: 06/01/2021] [Accepted: 06/12/2021] [Indexed: 01/20/2023] Open
Abstract
Rhododendron (Ericaceae) extracts contain flavonoids, chromones, terpenoids, steroids, and essential oils and are used in traditional ethnobotanical medicine. However, little is known about the immunomodulatory activity of essential oils isolated from these plants. Thus, we isolated essential oils from the flowers and leaves of R. albiflorum (cascade azalea) and analyzed their chemical composition and innate immunomodulatory activity. Compositional analysis of flower (REOFl) versus leaf (REOLv) essential oils revealed significant differences. REOFl was comprised mainly of monoterpenes (92%), whereas sesquiterpenes were found in relatively low amounts. In contrast, REOLv was primarily composed of sesquiterpenes (90.9%), with a small number of monoterpenes. REOLv and its primary sesquiterpenes (viridiflorol, spathulenol, curzerene, and germacrone) induced intracellular Ca2+ mobilization in human neutrophils, C20 microglial cells, and HL60 cells transfected with N-formyl peptide receptor 1 (FPR1) or FPR2. On the other hand, pretreatment with these essential oils or component compounds inhibited agonist-induced Ca2+ mobilization and chemotaxis in human neutrophils and agonist-induced Ca2+ mobilization in microglial cells and FPR-transfected HL60 cells, indicating that the direct effect of these compounds on [Ca2+]i desensitized the cells to subsequent agonist activation. Reverse pharmacophore mapping suggested several potential kinase targets for these compounds; however, these targets were not supported by kinase binding assays. Our results provide a cellular and molecular basis to explain at least part of the beneficial immunotherapeutic properties of the R. albiflorum essential oils and suggest that essential oils from leaves of this plant may be effective in modulating some innate immune responses, possibly by inhibition of neutrophil migration.

Abstract
In this study, an optimal method used to extract Annona squamosa pericarp oil (ASPO) was established according to the response surface model. The yield of ASPO was 1.45%. 8 fatty acids were identified from ASPO by GC-MS. Among them, (9Z)-9-Octadecenoic acid was abundant and accounted for 49.65%. The anti-hepatoma activities of ASPO were investigated against SMMC-7721 cell line in vitro and H22 cell line in vivo. Proteins associated with apoptosis in tumour tissue were quantified by western blot assay. The result revealed that ASPO had significant anti-hepatoma activities with IC50 value of 15.96 μg/mL in vitro and tumour inhibition rate of 54.14% at 50 mg/kg dose in vivo. Protein analysis showed that ASPO activated apoptosis by down-regulating Bcl-2, up-regulating Bax, cleaving caspase 9, cleaving caspase 8 and cleaving caspase 3 proteins. The possible mechanisms of apoptosis induced by ASPO were related to Fas/FasL/caspase-8/caspase-3 and Bcl-2/bax/caspase-9/caspase-3 pathways.
