Structure-radical scavenging activity relationships of hydroxytoluene derivatives
Research works proposed that radical scavenging activity of flavonoids is due to ring B, andthe remaining part of the molecule can be disregarded. Thus the objective of this work is toobserve whether hydroxytoluenes account the radical scavenging activity of flavonoid and toestablish structural requirements for their activity (as they showed appreciable activity) andelucidate a comprehensive me...

متن کاملStudies on the cytotoxicity of asterriquinone derivatives.
The antitumor agent, asterriquinone (ARQ) is a known metabolite isolated from the mycelium of Aspergillus terreus IFO 61231). YAMAMOTO et al. reported that ARQ analogues having a 2, 5-dimethoxy-p-benzoquinone moiety (ARQ dimethyl ether: ARQDMe)2,3) and the 2, 5-diamino-p-benzoquinone moiety (diamino ARQ: ARQDA)4) did not show any Cytotoxicity. As reported in our previous communication5), a new ...
متن کاملStructure and antiinflammatory activity relationships of wogonin derivatives.
A number of wogonin derivatives have been synthesized as congeners of wogonin and evaluated for their inhibitory activities of PGE2 production. Wogonin derivatives modified at the B ring of wogonin were obtained from 2,4-Dihydroxy-3,6-dimethoxyacetophenone (1) via several steps. Most wogonin derivatives exhibited much reduced inhibitory activities against COX-2 catalyzed PGE2 production compare...
متن کاملSynthesis and analgesic activity of novel Hydrazide and Hydrazine derivatives
The uses of non-steroidal anti-inflammatory drugs (NSAIDs) are limited by a variety of side effects. So research on preparing new analgesic agents is important. According to some reports about the analgesic activity of hydrazide and hydrazine derivatives a new series of these compounds were synthesized in order to obtain new analgesic compounds. The final compounds 10a-10e and 15a-15d were pre...
