Synthesis and biological activities of some new fluorinated coumarins and 1-aza coumarins.
A series of new fluorinated coumarins and 1-aza coumarins have been synthesized and the presence of fluorine in these molecules and its effect on their anti-microbial, anti-inflammatory and analgesic activities are discussed. The results of bioassay showed that these newly synthesized compounds containing fluorine exhibit moderate analgesic and excellent anti-inflammatory and potential anti-bac...
متن کاملTwo new coumarins from Talaromyces flavus.
Two new coumarins, talacoumarins A (1) and B (2), were isolated from the ethyl acetate extract of the wetland soil-derived fungus Talaromyces flavus BYD07-13. Their structures were elucidated by spectroscopic data (NMR, MS) analyses. The absolute configuration of C-12 in 1 was assigned using the modified Mosher's method, whereas that of C-12 in 2 was deduced via the circular dichroism data of i...
متن کاملNew monoterpenoid coumarins from Clausena anisum-olens.
Two new monoterpenoid coumarins: anisucumarin A (1) and B (2), a pair of epimers, were isolated from Clausena anisum-olens. Their structures were established based on extensive spectroscopic analyses.
متن کاملINTRODUCTION OF SOME NEW ARBUSCULAR-MYCORRHIZAL FUNGI (AMF) FROM CITRUS RHIZOSPHERE OF IRAN
During 2001-2002, a total number of 164 soil-root samples were collected from citrus orchards of six provinces, namely, Fars, Gilan, Mazandaran, Kerman, Hormozgan and Sistan va Baloochestan. Soil samples were decanted and centrifuged and spores were collected and examined. Out of 23 identified species, five species were recognized new to Iran mycoflora. New species are as follows: Gomus albidum...
متن کاملPHOTOREACTICITY (365 nm) OF SOME COUMARINS
The Authors have studied the capacity to photoreact with native DNA and r-RNA using six coumarins and four 4',5'-dihydro-furo-coumarins. Six of these substances have shown a definite photoreactivity both with DNA and r-RNA, even if in a very much lower extent in respect to that of skin-photosensitizing furocoumarins. The low capacity to photoreact with nucleic acids of these substances is discu...
