Various 6‐substituted pteridines and 5,6,7,8‐tetrahydropterins carrying photolabile functions at the side chain (see 7 , 20 – 22 , 34 – 36 , 38 , and 39 ) as well as at the 5‐position (see 27 – 29 ) were synthesized from pterin and from 6‐phenylpterin ( 1 ) and 6‐(hydroxymethyl)pterin ( 10 ). Attachment of the photoaffinity labels via ester bonds required a special protecting‐group strategy based upon acid‐labile (see 30 – 33 ) and β‐eliminating blocking groups (see 17 – 19 ). The 6‐(4‐azidophenyl)pterin ( 7 ) was obtained from 6‐phenylpterin ( 1 ) via intermediates 2 and 4 – 6 , due to the low solubility of simple pterins in general. The pteridine derivatives 21 , 22 , 25 , 26 , 28 , 29 , 32 , 33 , 35 , 36 , 38 , and 39 were screened as inhibitors of neuronal (type I) NO synthase (see Table) from porcine cerebellum, of which 22 , 35 , 36 , and 38 showed interesting inhibitory activity with similar potency and effectiveness. 相似文献

Three new diarylethenes 1 – 3 combined with quinoline derivatives have been synthesized. Through controlled chemical condition of deprotonation/protonation, they presented some new irreversible photochromic phenomenons under UV/Vis light irradiation in chloroform solution. It was found that 1 – 3 had well photoisomerization upon UV/Vis light irradiation in neutral chloroform solution. Addition of acid to the solution of the ring‐opening isomers of 1 – 3 produced 1oa – 3oa , which performed reversible photochromic behavior under UV/Vis light irradiation and reversed back to 1 – 3 under neutralizing with adding lewis base. However, addtion of base to neutral soluton of the ring‐opening isomers of 1 – 3 produced 1ob – 3ob , which could not change to the deprotonated ring‐closing isomers under UV light irradiation. 相似文献

Three new monosubstituted sucrose fatty acid esters, 1 – 3 , were isolated from Equisetum hiemale L., together with nine known compounds, 4 – 12 . Their structures were elucidated by spectroscopic analyses. Compounds 5, 6 , and 10 – 12 were isolated from the title plant for the first time. All these compounds were evaluated for their cytotoxic activity. However, none of them was cytotoxic. 相似文献
