cinnamate/atrophy

As an inherited disorder caused by initial death of rod photoreceptors, retinitis pigmentosa is currently untreatable and usually leads to partial or complete blindness. (2R, 3S)-Pinobanksin-3-cinnamate (PC) is a new flavonone isolated from the seed of Alpinia galanga Willd, and has been reported to

The photophysical properties of five methoxy-substituted 2-ethylhexylcinnamates were studied with experimental and theoretical methods. It was found that the fluorescence quantum yields varied strongly with the substitution pattern of the phenyl ring. A methoxy substitution at the meta position gave

The cDNAs encoding phenylalanine ammonia-lyase (PAL) and cinnamate 4-hydroxylase (C4H) were cloned from garlic (Allium sativum) using reverse transcription-polymerase chain reaction (RT-PCR) with degenerate primers and 5' and 3' rapid amplification of cDNA ends (RACE) PCR. Amino acid sequence

Phenylalanine ammonia-lyase (PAL) and cinnamate 4-hydroxylase (C4H) are important enzymes in the phenylpropanoid pathway and also in the accumulation of decursin (1) and decursinol angelate (2), which are major secondary metabolites in Angelica gigas. Using PCR with degenerate primers targeted to

Bornyl caffeate (1) was previously isolated by us from Valeriana (V.) wallichii rhizomes and identified as an anti-leishmanial substance. Here, we screened a small compound library of synthesized derivatives 1-30 for activity against schistosomula of Schistosoma (S.) mansoni. Compound 1 did not show

Flavor quality is of major importance to the consumer, but the flavor characteristics of beer appear to deteriorate greatly with time, at a rate depending on the composition of the beer and its storage conditions (notably pH). Prior to identifying the influence of pH on the development of the most

Most angiosperms encode a small family of 4-coumarate:CoA-ligases (4CLs) activating hydroxycinnamic acids for lignin and flavonoid pathways. The common rue, Ruta graveolens L., additionally produces coumarins by cyclization of the 4-coumaroyl moiety, possibly involving the CoA-ester, as well as
