Octanoic acid-13C4是具有13C标记的Octanoic acid (T3946)。Octanoic acid (Caprylic acid)是一种具有轻微腐臭味的油性液体，可用于生产酯类香料和染料。

Palmitoyl L-Carnitine-d3 Hydrochloride是棕榈酰 L-肉碱的氘代衍生物。棕榈酰 L-肉碱是一种长链酰基肉碱，由棕榈酸和肉碱缩合而成，在线粒体脂肪酸 β-氧化和能量代谢中起关键作用。在病理状态下（如心肌缺血），棕榈酰 L-肉碱会在细胞膜内积聚。研究表明，它能改变膜脂环境并调节 KATP 通路，从而影响心肌细胞的电生理特性。作为氘代标记物，该化合物主要在基于质谱（LC-MS/MS）的定量分析中用作内标，利用氘代诱导的药代动力学动力学同位素效应（KIE）来提高检测的精确度。

Enrofloxacin monohydrochloride (BAY Vp 2674 monohydrochloride) 为一种针对Mycoplasma bovis具有高效抗菌作用的抗生素，MIC90值为0.312 μg/mL。此外，Enrofloxacin monohydrochloride 亦展现出对牛痘病毒的抗病毒活性。

Urea-D4是Urea (T0738)的氘代物。Urea为强效蛋白质变性剂，通过直接和间接机制发挥作用。除此之外，它是有效的润肤剂和角质层分离剂，也被用作利尿剂。血尿素氮 (BUN)常用于评估肾功能。作为肥料中的氮源，Urea在化学工业中是重要的原料。

Lignoceric Acid (tetracosanoic acid) 是一种 24 碳饱和 (24:0) 脂肪酸，在发育中的大脑中合成，也是一种木质素生产的副产品。它能够用于研究 Zellweger 脑-肝-肾综合征和肾上腺脑白质营养不良。

ATP dipotassium (Adenosine 5'-triphosphate dipotassium) is a vital compound involved in energy storage and metabolism within living organisms. It plays a crucial role in supplying metabolic energy for driving pumps and acts as a coenzyme in cellular processes. Additionally, ATP dipotassium functions as a significant endogenous signaling molecule contributing to immunity and inflammation.

2-Phenylacetamide是一个片段分子，CAS号为103-81-1，可作为分子拼接、扩展和修饰的重要骨架，为新型候选药物的设计与筛选提供结构基础与研究工具，常用于药物发现、药物合成等相关研究。

Violacein is a bacterial metabolite originally isolated from C. violaceum that has antibacterial and antiprotozoal activities.[1] [2] It is produced by C. violaceum as a purple pigment in response to N-hexanoyl homoserine lactone , a property that has been modified to create a strain of C. violaceum used in detecting quorum-sensing molecules.[3] Violacein is active against Gram-positive bacteria, including B. subtilis and S. aureus (MICs = 0.8 and 1.6 µM, respectively). It is also active against P. falciparum, including chloroquine-susceptible and -resistant strains (IC50s = 0.85 and 0.63 µM, respectively).[2] It reduces parasitemia in a mouse model of nonlethal P. chabaudi chabaudi infection when administered at a dose of 7.5 mg/kg and increases survival in a mouse model of lethal P. chabaudi chabaudi infection. Violacein permeabilizes the cytoplasmic membrane of bacterial cells but does not affect the cell wall.[1]

Pristanic acid是由phytanic acid 经α-氧化生成的内源性支链脂肪酸，在过氧化物酶体中通过β-氧化途径进一步代谢。作为脂肪酸代谢产物，Pristanic acid 可作为配体激活PPARα，从而调控脂质代谢及能量稳态相关基因的表达。其代谢异常与多种过氧化物酶体相关疾病有关，包括齐薇格综合征、α-甲基酰基辅酶A消旋酶缺乏症以及婴儿型Refsum病等。
