Arcyriaflavin A is derived from Eudistoma sp. It inhibits D1-CDK4, B-CDK1 and CaMKII with IC50 values ​​of 0.14μM, 1.13μM and 0.025μM, respectively. Arcyriaflavin A also inhibits HCT-116 and NCI-H460 cells with IC50 values ​​of 0.85μM and 0.59μM, respectively.

Cafedrine (Cafedrin) is found in tea and coffee and has a central nervous system stimulant effect.Cafedrine is often used in a 20:1 combination with a fixed dose of cortisone in the study of acute hypotension.

Enniatin C is a membrane-active antibiotic with antimalarial activity that inhibits Mycobacterium tuberculosis, used in the study of fungal infections.

Lamellarin D (Lamellarine D), a hexacyclic pyrrolizidine alkaloid isolated from marine invertebrates, is a mitochondria-targeted topoisomerase I inhibitor and a pro-apoptotic agent.

L-Clausenamide is an alkaloid extracted from the leaves of the yellow bark (Clausena lansium (Lour) skeels) and can be used to improve cognitive function. L-Clausenamide inhibits beta-amyloid (Aβ) toxicity and prevents the formation of neurofibrillary tangles by inhibiting tau phosphorylation. L-Clausenamide has neuroprotective activity and can be used to modulate stimuli triggered by Aβ25-35. L-Clausenamide can be used to study neurological disorders like Alzheimer's disease.

Thiolutin (Acetopyrrothin) is an inhibitor of endothelial cell adhesion and produced by Streptomyces. Thiolutin shows antibiotic and anti-angiogenic properties. Thiolutin induces the phosphorylation of Hsp27 rapidly.

Kukoamine B mesylate is a novel cationic alkaloid derived from dermatophytes with antioxidant activity, inhibits LPS internalization in Kupffer and RAW 264.7 cells, and can be used to study acute inflammation and diabetes.

Amakusamine is an indole alkaloid from the sponge of Psammocinia sp. It inhibits RANKL-induced isolation of multinucleated osteoclasts and inhibits RANKL-induced multinucleated osteoclasts.
