2-Methylbutyrylcarnitine (chloride) acts as a gut microbial metabolite that targets integrin α2β1 on platelets, facilitating the activation of cytosolic phospholipase A2 (cPLA2) and enhancing platelet hyperresponsiveness. This compound further augments platelet hyperreactivity and promotes thrombus formation in mice. It is also characterized as a branched-chain acylcarnitine.

5-(3',4'-Dihydroxyphenyl)-γ-valerolactone is a gut microbial metabolite of (-)-epicatechin and possesses antioxidant activity.

Phepropeptin C is a microbial secondary metabolite that acts as a proteasome (proteasome) inhibitor, with an IC50 of 12.5 μg/mL.

Alazopeptin monohydrate is a microbial metabolite. Alazopeptin is an antibiotic, with moderate anti-trypanosomal.

Myxochelin A is a microbial metabolite found in *A. disciformis* with diverse biological activities. It exhibits activity against Gram-positive bacteria, including *B. cereus*, *S. aureus*, and *M. luteus*, but not against Gram-negative bacteria or fungi at a concentration of 80 μg/disc in an agar diffusion assay. Myxochelin A inhibits 5-lipoxygenase (5-LO) activity, with an IC50 value of 1.9 μM for the recombinant human enzyme. Additionally, it is cytotoxic to 26-L5 colon cancer cells at a concentration of 3 μg/ml.

4-Hydroxy Atorvastatin calcium salt is metabolised by cytochrome P450 CYP3A4 and has antimicrobial and anti-microbial activity.Atorvastatin is a lipid-lowering HMG-CoA reductase inhibitor.

(±)14(15)-EpETE, an eicosatetraenoic acid derivative containing an epoxy group, is an intestinal microbial lipid metabolite that attenuates cisplatin chemotherapy-induced nausea and vomiting in rats by inhibiting Substance P release through targeting GCG/PKA signaling and is commonly used to study inflammation and metabolism.
