Chelerythrine is a well-known protein kinase C inhibitor, can inhibit telomerase activity, it also can block the human P2X 7 receptor. Chelerythrine has antimanic, potential antiproliferative and antitumor effects, it has significant cytotoxic effect, independent of p53 and androgen status, on human prostate cancer cell lines. Chelerythrine chloride is a benzophenanthridine alkaloid.

(+)-Lirinidine has antioxidative activity, and it can significantly inhibit the proliferation of melanoma cells; it also shows potent inhibition of melanogenesis. Lirinidine exhibits significant inhibition of collagen, arachidonic acid and platelet activating factor-induced platelet aggregation.

Periplocymarin, a cardiac glycoside, has potential anti-cancer activity. Octreotide-conjugated periplocymarin demonstrates tumor selectivity and may be useful as a targeting agent to improve the safety profile of cardiac glycosides for cancer therapy.

Arjunetin, an insect feeding-deterrent and growth inhibitor, shows antioxidant and anti-inflammatory activities. It demonstrates significant inhibition of(Dipeptidyl peptidase-IV) DPP-IV enzyme, the DPP-IV Inhibitory activity translated into significant cardioprotective effects in the setting of diabetes.

6-Hydroxykaempferol is a competitive inhibitor of tyrosinase compared to L-DOPA, it shows also high antioxidant activities.

Glaucocalyxin A could potentially be developed as an antiplatelet and antithrombotic agent, can inhibit platelet p-selectin secretion and integrin activation by convulxin, is a GPVI selective ligand. Glaucocalyxin A has regulation of microglia activity, can attenuate lipopolysaccharide -stimulated neuroinflammation through NF-κB and p38 MAPK signaling pathways.Glaucocalyxin A may become a potential anti-fibrotic agent in Idiopathic pulmonary fibrosis (IPF) management, it can effectively ameliorate pulmonary fibrosis through the antagonism of leukocyte infiltration and proinflammatory cytokine production.

Indirubin is a potent cyclin-dependent kinases and GSK-3β inhibitor with IC50 of about 5 μM and 0.6 μM. Indirubin has anticancer, anti-inflammatory,antiviral,anti-allergic contact dermatitis effects. Each indirubin derivative acts on the DNA binding of NF-Y and represses the MDR1 gene promoter with tumor cell-type specificity.Indirubin derivatives have a potential to be used as an adjunct to antiviral therapy for the treatment of severe human H5N1 disease.

4'-demethylepipodophyllotoxin is an organic heterotetracyclic compound that is the 9- epimer of 4'-demethylpodophyllotoxin. It has a role as an antineoplastic agent. It is a member of phenols, an organic heterotetracyclic compound and a furonaphthodioxole.

Arnicolide D exerts strong cytotoxic activity on the human colon carcinoma HT-29 cell line.
