Spermidine (N-(3-Aminopropyl)-1,4-diaminobutane) 属于天然多胺，存在于核糖体和活组织中，在生物体内具有各种代谢功能。Spermidine 具有炎症减轻、调节脂质代谢、调节细胞生长和死亡的功能。

Spermidine trihydrochloride (4-Azaoctamethylenediamine trihydrochloride) 能够维持细胞膜稳定性，提高抗氧化酶特性，改善光系统 II (PSII) 以及相关基因表达，也能够显著抑制 H2O2和 O2.-含量。

Tenuazonic acid is a putative nonhost-selective mycotoxin isolated from Alternaria alternate. Tenuazonic acid blocks electron transport beyond primary quinone acceptor (QA) by interacting with D1 protein and it is a broad-spectrum and effective photosyste

[1,3-Bis(2,6-Diisopropylphenyl)imidazol-2-ylidene](3-chloropyridyl)palladium(II) dichloride 是一种有用的有机化合物，可用于生命科学领域的相关研究，其产品编号为 T66162。

Amicarbazone (BAY-MKH3586; BAY314666) is a potent PSII inhibitor, disrupting photosynthetic electron transport by binding to the Qb domain of photosystem II. This broad-spectrum herbicide is effective through foliar and root application, showcasing rapid absorption and translocation. However, its effectiveness can be compromised by common PSII inhibitor resistance. With an IC50 value indicating high potency, amicarbazone leads to chlorosis, stunted growth, tissue necrosis, and death in sensitive plants. Despite these severe effects, it exhibits good selectivity and outperforms atrazine as a herbicide, allowing for its application at lower doses compared to traditional photosynthetic inhibitors.

Dimidazon (BAS 29095) 是一种针对光合系统 II (PSII) 的弱电子传递抑制剂，它能阻碍 PSII 中电子从初级电子受体 Q 向光合系统 I 的传递。Dimidazon 有潜力在光合作用调控和杂草防除研究中得到应用。

Spermidine-d8(hydrochloride)是Spermidine trihydrochloride的氘代物。Spermidine hydrochloride能维持细胞膜稳定性，增强抗氧化酶活性，改善光系统II (PSII)及相关基因表达，还显著降低H2O2和O2.-的含量。

Spermidine-13C4 (hydrochloride) 是一种13C 标记的 Spermidine (trihydrochloride)。Spermidine hydrochloride 能维持细胞膜的稳定性，增强抗氧化酶的活性，并改善光系统 II (PSII) 以及相关基因的表达。此外，Spermidine hydrochloride 还能显著降低 H2O2 和 O2.- 的含量。
