-
, (2014/01/17)
Disclosed are methods, compounds, and compositions useful for increasing autophagy and promoting longevity. The methods, compounds, and compositions relate to urolithins and urolithin precursors and use thereof. Certain urolithins are represented by Formula I, while certain urolithin precursors are represented by Formula IV. The urolithin may be urolithin A, urolithin B, urolithin C, or urolithin D. The urolithin precursor may be ellagic acid or an ellagitannin. The methods include in vivo, ex vivo, and in vitro uses of the compounds and compositions.

Antioxidants have potential for the treatment of stroke and neurodegeneration, and chimeric compounds that combine a flavon-3-ol head group related to myricetin and a lipophilic decyl tail are known to protect membranes from oxidative damage at least as well as vitamin E. New flavon-3-ols that are highly hydroxylated in the B ring in ways not found in natural flavon-3-ols and bearing a lipophilic decyl tail have been prepared from trimethoxy-and tetramethoxybenzoic acids accessed by lithiation-carboxylation reactions. Direct enolate acylation was preferred over Baker-Venkataraman rearrangement when there were methoxy groups at both the 2-and the 6-position of the benzoic acid derivatives.

Phenstatin and its derivatives with the modified ring A have been synthesized, using plant allylpolyalkoxybenzenes as a starting material. The targeted molecules were evaluated in a phenotypic sea urchin embryo assay for antiproliferative activity. It was found that phenstatin ring A modifications yielded antimitotic compounds. The most effective myristicin derivative 7d (combretastatin A-2 analogue) was determined to be ca. 10 times more potent than phenstatin, displaying antimitotic tubulin-destabilizing activity at the same concentration range as combretastatins. In contrast to combretastatins, 7d featured the steric stability with potential for further design as anticancer agent.

, p. 2965 - 2968 (2007/10/02)
Besides agecorynin C, eupalestin and lucidin dimethyl ether, two new highly oxygenated flavones were isolated from Ageratum houstonianum.Their structures were established by spectroscopic and degradative evidence as 5,6,7,8,2',3',4',5'-octamethoxyflavone and 5,6,7,2',3',4',5'-heptamethoxyflavone. - Key Word Index: Ageratum houstonianum; Asteraceae; Eupatorieae; new octasubstituted and heptasubstituted flavones.
