Crocatin B is found in P. crocatum Ruiz & Pav. Crocatin B exerts anti-inflammatory activity by inhibiting the expression of TNF-α and ICAM-1. Crocatin B has anti-tumor activity.

2,5-Dimethoxy-3-glucopyranosylcinnamic alcohol is found in P. crocatum and Dirca palustris. 2,5-Dimethoxy-3-glucopyranosylcinnamic alcohol is a COX-I inhibitor. 2,5-Dimethoxy-3-glucopyranosylcinnamic alcohol has anti-inflammatory activity .

N-trans-Feruloyltyramine 4′-O-β-D-glucopyranoside is a phenolic amide glycoside compound found in Suaeda japonica. N-trans-Feruloyltyramine 4′-O-β-D-glucopyranoside exhibits antioxidant activity, capable of effectively scavenging DPPH free radicals and reducing the production of ROS induced by H₂O₂ in cells, thus protecting cells from oxidative stress damage. N-trans-Feruloyltyramine 4′-O-β-D-glucopyranoside is promising for research of cardiovascular diseases and neurodegenerative diseases.

Cuneataside E is a phenylpropanoid glycoside compound found in Lespedeza cuneata. Cuneataside E exhibits hepatoprotective activity against the toxicity induced by N-acetyl-p-aminophenol (APAP) in the human hepatocellular carcinoma cell line HepG2. Cuneataside E is promising for research of liver diseases.

Phenylmethyl 6-O-α-L-arabinofuranosyl-β-D-glucopyranoside (Compound 12) is a nerve growth factor (NGF) secretion promoter, which is found in plants of the genus Piper. Phenylmethyl 6-O-α-L-arabinofuranosyl-β-D-glucopyranoside is promising for research of neurodegenerative diseases (such as Parkinson's disease and Alzheimer's disease) and diabetic polyneuropathy.

Icariside D1 (Compound 9) is a flavonoid glycoside compound with antioxidant and anti-inflammatory activities, which is found in plants such as Epimedium. Icariside D1 is also a regulator of estrogen receptors. Icariside D1 is promising for research of osteoporosis, male infertility and female reproductive dysfunction and cancers.

[(2E,4E)-Octadienoyl]-N-isobutylamide (compound 2) is an isobutylamide that can be isolated from pepper seeds.

Tetrahydropiperine (Standard) is the analytical standard of Tetrahydropiperine (HY-N4205). This product is intended for research and analytical applications. Tetrahydropiperine is an orally effective, selective inhibitor of NF-κB and MAPKs, and an activator of the PI3K/Akt/mTOR pathway. Tetrahydropiperine reduces the production of pro-inflammatory cytokines such as TNF-α, IL-6, and nitric oxide (NO) by inhibiting the nuclear translocation of NF-κB and the phosphorylation of MAPKs such as ERK, JNK, and p38. At the same time, Tetrahydropiperine inhibits excessive autophagy by activating the PI3K/Akt/mTOR pathway, protecting neurons from oxidative damage. Tetrahydropiperine has anti-inflammatory, anti-apoptotic, and neuroprotective effects, and is mainly used in the study of inflammatory diseases (such as endotoxemia, arthritis) and neurological diseases such as ischemic stroke.
