| In vitro | Cytotoxic and Antimicrobial Diterpenes Isolated from Hyptis Dilatata.[Reference: WebLink]Current Bioactive Compounds, 2015, 11(3):-.Diterpenes 7-Ethoxyrosmanol (1) and carnosol (2) were isolated and identified from the extracts of Hyptis dilatata collected in the Orinoco region, Colombia, used traditionally in this region for the treatment of wound infections of cattle. Their stereostructures were elucidated by ID and 2D NMR experiments including 1H, 13C, COSY, HSQC, HMBC and NOESY. Although compound 1 has been reported previously, its NMR assignments were revised, completed and corrected. These compounds showed a specific antimicrobial activity against Gram (+) strains. |

Investigation of In-Vitro Antioxidant and Electrochemical Activities of Isolated Compounds from Salvia chamelaeagnea P.J.Bergius Extract.[Pubmed:31013747]
Antioxidants (Basel). 2019 Apr 12;8(4). pii: antiox8040098.
We have investigated the in-vitro antioxidant activity and electrochemical redox properties of a number of natural compounds (carnosol, carnosic acid, 7-Ethoxyrosmanol, ursolic acid, rosmanol and ladanein) isolated from the methanolic extract of Salvia chamelaeagnea collected from the Cape floristic region, South Africa. The results from trolox equivalent antioxidant capacity (TEAC), ferric-ion reducing antioxidant parameter (FRAP) oxygen radical absorbance capacity (ORAC), as well as the inhibition of Fe(2+)-induced lipid peroxidation showed strong antioxidant capacities for carnosol and rosmanol. A structural analysis of the compounds suggests that multiple OH substitution, conjugation and lactone ring in carnosol and rosmanol are important determinants of the free radical scavenging activity and electrochemical behavior. Pharmacophore generated demonstrates H-donor/acceptor capabilities of the most active compounds. Rosmanol, when compared to other compounds, exhibits the lowest oxidation potential value with an anodic peak potential (Epa) value of 0.11 V, indicating that rosmanol has the highest antioxidant power, which is in good agreement with ORAC and lipid peroxidation experiments. The lipophilic nature of carnosol, carnosic acid and rosmanol enhanced their absorption and activity against oxidative stress related to the treatment of age-related diseases. These results confirm the first report on the in-vitro antioxidant and electrochemical activities of S. chamelaeagnea constituents and underline the medicinal uses of this plant as natural preservatives for skin ageing or in pharmaceutical applications.
Phenolic diterpenes derived from Hyptis incana induce apoptosis and G(2)/M arrest of neuroblastoma cells.[Pubmed:23155243]
Anticancer Res. 2012 Nov;32(11):4781-9.
BACKGROUND: Neuroblastoma is one of the most commonly encountered solid tumors in the pediatric age group, and the prognosis of patients with advanced neuroblastoma is very poor. In this study, the antitumor effects of five phenolic diterpenes derived from Hyptis incana (Lamiaceae), a Brazilian medicinal plant, were examined on neuroblastoma cells. MATERIALS AND METHODS: Cytotoxicity was assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptotic nuclear shrinkage was monitored by Hoechst 33342 staining. The cell-cycle status was evaluated by flow cytometry and protein alterations were monitored by western blotting. Differentiated cells were photographed and counted in a randomized fashion. RESULTS: All of the examined compounds exhibited significant cytotoxicity towards the neuroblastoma cells. In particular, 7-Ethoxyrosmanol had a high degree of efficacy. Nuclear condensation and degradation of procaspase-3 and -9 were observed after treatment of the cells with these compounds. Moreover, phenolic diterpenes induced cell-cycle arrest in the G(2)/M phase. Rosmanol and epirosmanol tended to induce differentiation. CONCLUSION: Phenolic diterpenes isolated from H. incana have multiple antitumor effects on neuroblastoma cells.
Semisynthesis of rosmanol and its derivatives. Easy access to abietatriene diterpenes isolated from the genus Salvia with biological activities.[Pubmed:12141857]
J Nat Prod. 2002 Jul;65(7):986-9.
The known diterpenes rosmanol (3), rosmaquinone (4), 7-methoxyrosmanol (5), 7-Ethoxyrosmanol (6), galdosol (7), and epirosmanol (8) have been obtained by partial synthesis from carnosol (2), an abundant natural product present in Salvia species. The physical and spectroscopic data of these semisynthetic diterpenes were identical to those of authentic natural samples and with data reported in the literature. These abietane diterpenes have very interesting biological activities and are present in the genus Salviain low quantities; thus, the semisynthetic approach described here represents an efficient alternative method to obtain these compounds. Additionally, the known diterpene 16-hydroxyrosmanol (10) and a new aromatic diterpene 11 were obtained from 16-hydroxycarnosol (9) by reaction with Ph3P/NBS in CH2Cl2. The structure of the new compound 11 was established from its spectroscopic data as 12,16-epoxycarnosol.
