Bestatin (Ubenimex) competitively inhibits many aminopeptidases, including B, N and leucine aminopeptidases. Ubenimex is a microbial metabolite and dipeptide with potential immunomodulatory and antitumor activities. Aminopeptidases has been implicated in the process of cell adhesion and invasion of tumor cells. Therefore, inhibiting aminopeptidases may partially attribute to the antitumor effect of ubenimex. This agent also activates T lymphocyte, macrophage, and bone marrow stem cell as well as stimulates the release of interleukin-1 and -2, thus further enhances its antitumor activity.

Isotretinoin (13-cis-Retinoic acid) binds to and activates nuclear retinoic acid receptors (RARs), which act as transcription factors that promote cell differentiation and apoptosis. This naturally occurring retinoic acid has potential antineoplastic activity, exhibits immunomodulatory and anti-inflammatory responses, and inhibits ornithine decarboxylase, thereby decreasing polyamine synthesis and keratinization.

Patchouli alcohol (Patchoulol) is a naturally occurring tricyclic sesquiterpenoid found in patchouli oil. It is a key bioactive component known for its immunomodulatory, anti-inflammatory, antioxidant, antitumor, antibacterial, anti-atherosclerotic, antiemetic, and sedative properties.

Notoginsenoside R1 (Sanchinoside R1) has been shown to exhibit antioxidant, antiapoptotic, anti-inflammatory, and immune-stimulatory properties.

Stigmasterol (Stigmasterin) is a phytosterol with major functions in the maintenance of cell membrane structure and physiology. Stigmasterol lowers cholesterol levels and has anti-tumor, anti-inflammatory, and immunomodulatory effects.

Tripterin (Celastrol) is a natural product, a proteasome inhibitor that inhibits the pancreatic rennet-like activity of the 20S proteasome (IC50=2.5 μM). Tripterin has anti-inflammatory, anti-infectious, and immunomodulatory properties.

Allicin exerts antioxidant, bactericidal, anti-cancer, anti-inflammatory activities, it exerts an inhibitory immunomodulatory effect on intestinal epithelial cells. Allicin could significantly inhibit vascular smooth muscle cells' proliferation and migration induced by insulin, which may be related to the inhibition of the activation of ERK signal path. Allicin is beneficial in reducing blood cholesterol, triglycerides levels and systolic blood pressure in hypercholesterolemic rats, it may beneficially affect two risk factors for atherosclerosis-hyperlipidemia and hypertension.

Zerumbone is a natural monocyclic sesquiterpene first isolated from rhizomes of the wild ginger Z. zerumbet.It has also been shown to have anti-oxidant and anti-inflammatory activities, contributing to immunomodulatory and hepatoprotective effects.
