PHOTOREACTICITY (365 nm) OF SOME COUMARINS
نویسنده
چکیده
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 discussed, also in connection with the absence of skin-photosensitizing activity.

Simultaneous determination of five active compounds in chimonanthus nitens by double-development HPTLC and scanning densitometry
BACKGROUND Chimonanthus nitens (family Calycanthaceae), Shanlamei in Chinese, is an unique species in China. The extract of dried leaves of Chimonanthus nitens has anti-inflammatory, antipyretic and antitussive effects. Terpenes, coumarins, and flavonoids are usually regarded as the main active components. Therefore, simultaneous determination of these compounds is very important to control the...
متن کاملSpectroscopic parameters of the cuticle and ethanol extracts of the fluorescent cave isopod Mesoniscus graniger (Isopoda, Oniscidea)
The body surface of the terrestrial isopod Mesoniscusgraniger (Frivaldsky, 1863) showed blue autofluorescence under UV light (330-385 nm), using epifluorescence microscopy and also in living individuals under a UV lamp with excitation light of 365 nm. Some morphological cuticular structures expressed a more intense autofluorescence than other body parts. For this reason, only the cuticle was an...
متن کاملNew caged coumarin fluorophores with extraordinary uncaging cross sections suitable for biological imaging applications.
Photocaged fluorescent molecules are important research tools for tracking molecular dynamics with high spatiotemporal resolution in biological systems. We have designed and synthesized a new class of caged coumarin fluorophores. These coumarin cages displayed more than 200-fold fluorescence enhancement after UV photolysis. Remarkably, the uncaging cross section of a 1-(2-nitrophenyl)ethyl (NPE...
متن کاملFluorescence of coumarins and xanthenes after two-photon absorption with a pulsed titanium-sapphire laser.
Fluorescence emission after two-photon absorption of coumarins and xanthenes in an alcoholic solution was measured in the tuning range of a femtosecond-pulsed titanium-sapphire laser (750-840 nm). Xanthenes, which have a low one-photon absorption in the near UV, show a higher fluorescence signal after two-photon absorption than the UV-excitable coumarins. When fluxes of 10(28) photons/(cm(2) s)...
متن کاملA comparison of the photosensitizing potential of trovafloxacin with that of other quinolones in healthy subjects.
Treatment with some quinolones is associated with an abnormal skin reaction following exposure to sunlight (photosensitivity). The objective of the current study was to compare the photosensitizing potential of a new quinolone, trovafloxacin, with that of ciprofloxacin, lomefloxacin and placebo. Forty-eight healthy males (age range 19-45 years) were randomized to receive a 7 day course of treat...
