Anti-inflammatory agent 11 inhibits Mtb H37Rv and M299 growth, with MIC₅₀ (minimum inhibitory concentration 50%) of 1.3 and 6.9 μM, respectively. Anti-inflammatory agent 11 inhibits NO through the suppression of iNOS expression, and also inhibited the production of TNF-α and IL-1β. Anti-inflammatory agent 11 can be used for tuberculosis (TB) research.

Carbuterol (SKF 40383-A) is a selective β₂-adrenergic receptor agonist that primarily targets bronchial smooth muscle, exhibiting significant bronchodilatory and anti-allergic activity. Carbuterol can directly inhibit the immunologically induced release of histamine and slow-reacting substance of anaphylaxis (SRS-A), thereby alleviating allergic responses. Carbuterol exerts mild β₁-mediated cardiac stimulation and is applicable to studies related to respiratory and immune-related diseases such as asthma and allergic disorders.

Garcinone C (Standard) is the analytical standard of Garcinone C. This product is intended for research and analytical applications. Garcinone C, a xanthone derivative, is a natural compound extracted from Garcinia oblongifolia that is used as an anti-inflammatory, astringency and granulation-promoting medicine, and has potential cytotoxic effects on certain cancers. Garcinone C stimulates the expression levels of ATR and 4E-BP1, arrests the cell cycle, inhibits cell viability of the human Nasopharyngeal carcinoma (NPC) cell lines CNE1, CNE2, HK1 and HONE1 in a time‑ and dose‑dependent manner through inhibition of Hedgehog signaling pathway. Garcinone C is orally active.

Artepillin C (Standard) is the analytical standard of Artepillin C (HY-N10319). This product is intended for research and analytical applications. Artepillin C is an orally active CREB/CRTC2 inhibitor and TRPA1 covalent agonist (EC₅₀=1.8 μM). Artepillin C inhibits CREB/CRTC2-mediated gene transcription and downregulates BMAL1 expression to regulate glucose and lipid metabolism. Artepillin C can also activate TRPA1 channels to induce spicy taste signals. Artepillin C can inhibit tumor cell proliferation, induce apoptosis, improve insulin resistance and inhibit liver lipid synthesis. Artepillin C can be used in the study of metabolic syndrome, tumor prevention and treatment, and inflammation.
