摘要:Stereoisomers of the monoterpene epoxycarvone (EC), namely (+)-cis-EC, (−)-cis-EC, (+)-trans-EC, and (−)-trans-EC, were comparatively evaluated for anticonvulsant activity in specific methodologies. In the pentylenetetrazole (PTZ)-induced anticonvulsant test, all of the stereoisomers...

摘要:... In the present study, Fuco and its stereoisomers 9'Z-Fuco, 13Z- and 13'Z-Fuco were extracted from Laminaria japonica Aresch. They were isolated and purified by silica gel column chromatography, Sephadex LH-20, and reversed-phase HPLC. The radical-scavenging activities of the ...

摘要:Using a behavioral approach, it was shown that stereoisomers and other derivatives of amino acids (Ala, Glu, Gln; 0.1–0.01 М) have different palatability to fish (three-spined stickleback Gasterosteus aculeatus ). The palatability of L-α-Ala is higher than of D-α-Ala or...

摘要:... Both stereoisomers were resolved by gas chromatography on a polar capillary column and detected in more than 60 biotic (e.g. marine mammals, birds, human milk) and abiotic samples (fat deposits in kitchen hoods) from different areas all over the world. The stereoisomer dis...

摘要:... Stereoisomers of these compounds with high optical purity were synthesized from (+)- and (−)-α-pinenes for the first time in this work. The structure of (4 S )- 4b isomer was confirmed by the XRD data. Studies of analgesic activity of the resulting products demonstrat...

摘要:Abstract(#br)Metolachlor is a chiral herbicide consisting of four stereoisomers, which is typically used as a racemic mixture or is enriched with the herbicidally active 1′ S -isomers. Because studies on the enantioselective behavior of phyto-biochemical processes and the e...

摘要:... Although attention has been paid to the development of selective G-quadruplex ligands, few studies have focused on the binding affinity of stereoisomers towards G-quadruplex, which will be conducive to support the optimal design of G-quadruplex ligands in future studies. Here...

摘要:...(#br)Because carotenoids are extremely sensitive to UV light and oxygen, they occur in nature as several Z/E stereoisomers which can differ considerably in their biological effectiveness. With particular regard to dietary supplementation we have focussed on identification and ...

摘要:Abstract(#br)During the laboratory optimization and the late phase manufacturing studies of the cholesterol absorption inhibitor Ezetimibe 1 , the formation of several stereoisomers was observed. To study the complete stereoisomer profile of Ezetimibe 1 , we have synthesized and ...

摘要:... Obviously, direct dispose of the other three undesired stereoisomers will cause significant waste and increase the unnecessary cost of production. Here, we developed an efficient, facile and scalable process for recycling the inactive stereoisomers of Bedaquiline. All these i...
