Antibacterial mono- and sesquiterpene esters of benzoic acids from Iranian propolis
BACKGROUND Propolis (bee glue) has been used as a remedy since ancient times. Propolis from unexplored regions attracts the attention of scientists in the search for new bioactive molecules. RESULTS From Iranian propolis from the Isfahan province, five individual components were isolated: the prenylated coumarin suberosin 1, and four terpene esters: tschimgin (bornyl p-hydroxybenzoate) 2, tsc...
متن کاملAntibacterial diterpenic acids from Brazilian propolis.
Four labdane-type diterpenic acids and syringaldehyde were isolated and identified from Brazilian propolis. All the compounds exhibit antibacterial activity. The diterpenes, found for the first time in propolis, are typical for some Araucaria species and thus indicate a possible plant source of Brazilian propolis.
متن کاملGas phase measurements of mono-fluoro-benzoic acids and the dimer of 3-fluoro-benzoic acid.
The microwave spectrum of the mono-fluoro-benzoic acids, 2-fluoro-, 3-fluoro-, and 4-fluoro-benzoic acid have been measured in the frequency range of 4-14 GHz using a pulsed beam Fourier transform microwave spectrometer. Measured rotational transition lines were assigned and fit using a rigid rotor Hamiltonian. Assignments were made for 3 conformers of 2-fluorobenzoic acid, 2 conformers of 3-fl...

گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
Synthesis and Biological Evaluation of Novel Mono Acid Esters Derived from the Constituents of Urtica pilulifera
Abstract: New mono acid esters have been synthesized from the reaction of benzoic acid and mono-hydroxybenzoic acids with 2-phenoxyethanol separated from Urtica pilulifera, characterized, and screened for possible antioxidant, antifungal, antimicrobial and anticancer activities. These phenolic acid esters gave various degrees of free radical scavenging, but the values were lower than that of α-...
