3β-Hydroxylanosta-8,24-dien-21-al 是一种具有肿瘤促进抑制作用的羊毛甾烷型三萜，能有效减少小鼠乳头状瘤发生的百分比。

(22S,24E)-3β,22-Diacetoxylanosta-7,9(11),24-trien-26-oic acid (compound 15) 为具有抗结核活性的化合物，对结核分枝杆H37Ra的最小抑菌浓度（MIC）为12.5 μg mL，并展现出对Vero细胞的细胞毒性，其半数抑制浓度（IC50）值为32 μM[1]。

3beta-Hydroxylanosta-8,24-diene-21-al 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 T123844。

(S)-Pro-xylane, also known as (S)-Hydroxypropyl tetrahydropyrantriol, is the S-enantiomer of Pro-xylane. Pro-xylane is a biologically active C-glycoside that functions as an activator of glycosaminoglycans (GAGs) biosynthesis in aqueous media.

Arabinoxylan 是一种主要存在于单子叶草类作物细胞壁中的半纤维素多糖。其结构是由 β-(1→4)-连接的木吡喃糖基残基骨架构成。

Uvariol (21-Hydroxylanosterol)为一自Piptostigma fugax根部提取得到的天然化合物。

5-Hydroxy Lansoprazole Sulfide is an inhibitor of fatty acid synthase (FASN). FASN, which is responsible for de-novo synthesis of lipids, has been found to be overexpressed in cancerous tissue. 5-Hydroxy Lansoprazole Sulfide specifically inhibits enoyl reductase, and was found to more effectively inhibit FASN function than lansoprazole and was also more efficient at regulating NHEJ repair of oxidative DNA damage via PARP1.

JMN13497 is an precursor compound to for synthesis of scytonemin. Scytonemin is a biological pigment synthesized by many strains of cyanobacteria, including Calothrix sp., Lyngbya aestuarii, and others. Scytonemin is also a potent PKL1 inhibitor, which inhibits cell proliferation and arrests cell cycle through downregulating Plk1 activity in many cancel cells. Scytonemin was able to inhibit the proliferation of three myeloma cells in a dose-dependent manner, while U266 was the most sensitive one to scytonemin. Scytonemin , representing a novel Plk1 inhibitor, induced the inhibition of cell growth and cell cycle arrest in multiple myeloma cells by specifically decreasing Plk1 activity. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https: www.medkoo.com page naming).

AF53 is an kind of alpha-L-arabinofuranosidase containing a noncatalytic xylan-binding domain.

Xylotetraose 是木聚糖的水解产物，可用于酶生化分析。Xylan 是由木糖单元组成的多糖，主要包含由纤维素连接的 β-D- 木糖单位。
