A series of C4-substituted tertiary nitrogen-bearing 2′-hydroxychalcones were designed and synthesised based on a previous mixed type acetylcholinesterase inhibitor. Majority of the 2′-hydroxychalcone analogues displayed a better inhibition against acetyl

Paragraph 0079-0082, (2016/10/10)
The present invention relates to a flavokawain derivative or a pharmaceutically acceptable salt thereof having an activity for inhibiting Hsp90 and a medical use thereof wherein the flavokawain derivative comprises good effect of inhibiting Hsp90 and accordingly leads to decomposition of Hsp 90 client protein causing diseases related to cancer or neurodegenerative diseases by inhibiting Hsp90, thereby being used in drug medicine and healthy food products for preventing or treating Hsp 90 which is a mediated disease like diseases related to cancer or neurodegenerative diseases.COPYRIGHT KIPO 2015
Antispasmodic activity of xanthoxyline derivatives: Structure-activity relationships
Filho,Miguel,Nunes,Calixto,Yunes
, p. 473 - 475 (2007/10/02)
The antispasmodic activity of several xanthoxyline derivatives against acetylcholine-induced contraction of the guinea pig ileum was evaluated in vitro. The acetophenones with two methoxyl groups, mainly in the 3,4 positions, exhibited potent antispasmodic activity. Modification of the hydroxyl group in xanthoxyline by the introduction of benzoyl, acetyl, or tosyl groups produced inactive compounds, whereas the introduction of benzyl or p-methoxybenzyl groups furnished compounds that were four- to eight-fold more potent than xanthoxyline. In marked contrast, the introduction of a methyl group gave a compound that caused contractant activity. Modification of the carbonyl group of xanthoxyline lead to inactive compounds, whereas the condensation of xanthoxyline with benzaldehydes gave chalkones that were about fivefold more potent than xanthoxyline. The introduction of benzyl and styrene groups, on the basis of the similarity with papaverine, improves the antispasmodic action of the xanthoxyline derivatives. Our results suggest that the methoxyl and carbonyl groups are critical structural points for the antispasmodic activity of xanthoxyline derivatives. The hydroxyl group improves antispasmodic activity, but is not fundamental to its manifestation.
