Pheophytin pheophorbide hydrolase (pheophytinase) is involved in chlorophyll breakdown during leaf senescence in Arabidopsis

, 2009
During leaf senescence, chlorophyll is removed from thylakoid membranes and converted in a multistep pathway to colorless breakdown products that are stored in vacuoles.

Image_1_Exploring the potential of pheophorbide A, a chlorophyll-derived compound in modulating GLUT for maintaining glucose homeostasis.pdf

IntroductionPheophorbide A, a chlorophyll-breakdown product, is primarily investigated for its anti-oxidant and anti-inflammatory activity. Recent reports on pheophorbide A have shown its potential in lowering blood glucose levels, thus leading to the ...

Pheophorbide A from Solanum diflorum interferes with NF-κB activation

, 2001
Continuing our search for biogenic NF-κB inhibitors we investigated Solanum diflorum, used by the Istmo Sierra Zapotec Indians of Mexico in the treatment of inflammatory skin conditions. It became obvious very early that the active substance seems to be

Co-delivery of doxorubicin and pheophorbide A by pluronic F127 micelles for chemo-photodynamic combination therapy of melanoma

, 2018
In this work, doxorubicin (DOX)-loaded pheophorbide A (PheoA) modified Pluronic F127 (F127) micelles (DOX/F127-PheoA micelles) were developed for combined chemo-photodynamic therapy of melanoma.

Characterization of the pheophorbide a oxygenase/phyllobilin pathway of chlorophyll breakdown in grasses [PDF]

, 2018
MAIN CONCLUSION Although the PAO/phyllobilin pathway of chlorophyll breakdown is active in grass leaf senescence, the abundance of phyllobilins is far below the amount of degraded chlorophyll.

Impact of Passive Solar Drying and Storage on Secondary Plant Metabolites and Nitrate Contents of Abyssinian Mustard, Amaranth, and Pumpkin Leaves

Journal of Food Science, Volume 91, Issue 1, January 2026.
ABSTRACT The present study compared the effect of passive direct solar dryer (PDSD) and passive indirect solar dryer (PISD), each followed by a 30‐day storage period, on the secondary plant metabolite and nitrate contents of amaranth, Abyssinian mustard, and pumpkin leaves.

Chlorophyll breakdown: Pheophorbide a oxygenase is a Rieske-type iron-sulfur protein, encoded by the accelerated cell death 1 gene

, 2003
Chlorophyll (chl) breakdown during senescence is an integral part of plant development and leads to the accumulation of colorless catabolites. The loss of green pigment is due to an oxygenolytic opening of the porphyrin macrocycle of pheophorbide (pheide)

Pheophorbide b ethyl ester from a chlorella vulgaris dietary supplement

Acta Crystallographica Section E, 2008
In the title compound, C37H38N4O6, four five-membered nitrogen-bearing rings are nearly coplanar. Two N atoms in two these five-membered rings have attached H atoms, which contribute to the formation of intramolecular N—H...N hydrogen bonds [N...N =

Histological Changes of Hypersensitized Rats by Pheophorbide

Eiyo To Shokuryo, 1977
野沢菜漬物中に含まれるヘオホーバイドによるラットの光過敏症の成立とそのメカニズム解明のため, 今回はヘオホーバイドのケイ光性を利用し, ラットの体内分布を観察した。その結果, 網内系細胞の多い大網膜, 脾臓への取り込みが顕著であった。また, 多少, 心臓, 肝臓への取り込みも見られたが, それほど大きなものではなかった。さらに, 光過敏症によってラットの臓器 (脳, 胸腺, 肺臓, 心臓, 肝臓, 副腎, 腎臓, 脾臓, 胃, 腸, 子宮, 膀胱, 筋肉, 背の皮膚) が組織学的にどのような変化を受けているのかを観察するため光学顕微鏡をつかって検討した結果, 脾臓において, とくに著しい変化が認められた。リンパ濾胞のくずれ, 細胞の崩壊が顕著であること, また, この崩壊細胞は濾胞内 (白髄 ...
