Disease relevance of BETA-IONONE

 

High impact information on BETA-IONONE

 

Biological context of BETA-IONONE

  • Together, these observations indicate that in bleach-adapted rods beta-ionone activates phototransduction in the dark [2].
  • These more polar products are presumed to result from multiple hydroxylations on the beta-ionone ring [10].
  • From this recombinant strain the enzyme was purified by immuno-affinity chromatography and its cyclization activity characterized as a two-step reaction in which both sides of the lycopene molecule are cyclized to beta-ionone rings with the monocyclic gamma-carotene as an intermediate [11].
  • The biotransformation of therapeutic retinoids containing the beta-ionone ring system is likely to involve the microsomal ATRA 4-hydroxylase P450 [12].
  • From the N-BuOH soluble fraction of an MeOH extract of DENDRANTHEMA SHIWOGIKU, two new beta-ionone glucosides and roseoside were isolated, the structures of the new compounds elucidated were 2 and 3, respectively, on the basis of spectroscopic data and the results of an enzymic hydrolysis of 2 [13].

Associations of BETA-IONONE with other chemical compounds

 

Gene context of BETA-IONONE

  • Both beta-ionone and geraniol inhibited CDK 2 activity and dose-dependently decreased the expression of cyclins D1, E, and A, and CDK 2 and 4, without changing the expression of p21cip1 or p27kip1 [3].
  • W(thereby the oxygen diffusion-concentration product) is larger in the meta II-enriched sample than in rhodopsin, indicating light-induced conformational changes of opsin around the beta-ionone binding site [20].
  • However, the levels of TIMP-1 and TIMP-2 transcripts were elevated in cells treated with beta-ionone in a dose-dependent manner [22].
  • CONCLUSION: beta-ionone can inhibit the proliferation of SGC-7901 cells, upregulate the expression of TIMP-1 and TIMP-2 expression, and may influence metastasis of cancer [22].
  • The effects of beta-ionone on MMP-2 and MMP-9 activities in SGC-7901 cells were not observed [22].
