Euphohelioscopin A, an activator of protein kinase C (PKC), it inhibits proliferation and induces differentiation of the myeloid leukemia cell lines THP-1 and HL-60. Euphohelioscopin A has anti-inflammary activity, it exhibits moderate inhibitory activity
Epitaraxerol shows moderate antifungal activity against C. albicans and low antimicrobial activity against T. mentagrophytes, A. niger, S. aureus, E. coli, P. aeruginosa, and B. subtilis.
20-Deoxyingenol 3-angelate and ingenol 20-acetate 3-angelate are known as promoters of tumors of mouse skin. 20-Deoxyingenol 3-angelate can induce significant platelet aggregation accompanied by induction of phosphorylation of PKC substrates in platelets,
Pepluanin A, shows a very high activity for a jatrophane diterpene, outperforming cyclosporin A by a factor of at least 2 in the inhibition of Pgp-mediated daunomycin transport.
Jolkinol A can inhibit both MCF-7 (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer) cell lines, with GI50 values ranging between 40.9 microM and 95.3 microM.
(±)-Boehmenan shows potent protein-tyrosine phosphatase 1B (PTP1B) inhibitory activity in vitro with the IC(50) values of 43.5 uM, it inhibits PTP1B activity in a competitive manner. Boehmenan exhibits the potent cytotoxic effects against many cancer cell
ent-11alpha-Hydroxyabieta-8(14),13(15)-dien-16,12alpha-olide shows significant cytotoxic activity against ANA-1 and Jurkat cells with IC50 values 7.12 x 10(-3) and 1.79 x 10(-2) microM.
31-Norlanostenol is a triterpene isolated from the latex of Euphorbia officinarum. It can act as an efficient insect growth regulator on S. frugiperda and Tenebrio molitor.
(24R)-Cycloart-25-ene-3beta,24-diol may be an anti-tumor promoter, it exhibits inhibitory effects on both Epstein-Barr virus early antigen (EBV-EA) and (+/-)-(E)-methtyl-2-[(E)-hydroxyimino]-5-nitro-6-methoxy-3- hexemide (NOR 1) activation.
ent-16alpha,17-Dihydroxyatisan-3-one and ent-16alpha,17-dihydroxykauran-3-one have apoptosis induction activities on L5178 human MDR1 gene-transfected mouse lymphoma cells.
