Distinct immunosuppressive effect by Isodon serra extracts.[Pubmed:16275630]
Int Immunopharmacol. 2005 Dec;5(13-14):1957-65.
Distinct effect of ent-Kaurene Diterpenoids from Isodon serra on abnormal proliferation of murine lymphocytes was examined with MTT assay and Flow Cytometry Analyses (FCAS). After choosing the most appropriate monomer from these Diterpenoids, we introduced mouse tumescence model to investigate whether it could impact cytokine production in vivo with ELISA assay. The result of MTT assay showed that four ent-Kaurene Diterpenoids could effectively suppress the murine splenic T lymphocytes overproduction stimulated by Concanavalin A, while inhibitive effect was softer on normal sleep lymphocytes than the stimulated ones. Among four ent-Kaurene Diterpenoids, Enmein was the most sensitive one with IC50/EC50 equaling to 1.55. This inhibitive activity was due to interfering DNA replication in G1-S stage and to regulating cell cycle according to flow cytometry analyses (FCAS) result. Xylene-induced mouse tumescence model result further suggested that Enmein depressed the murine ear swelling extent and the level of Interleukin-2 in blood serum in a dose-dependent manner. In conclusion, it demonstrated that four ent-Kaurene Diterpenoids from I. serra had distinct immunosuppressive effect in vitro and in vivo systems, which primarily differentiated Enmein from the others. The experimental results provided insight into a potential immunosuppressive action of Enmein as a promising drug, though profound mechanism remained to be further studied.
Cytotoxic ent-kaurane diterpenoids from Isodon sculponeata.[Pubmed:12391557]
Planta Med. 2002 Oct;68(10):921-5.
Four new ent-kaurane diterpenoids, sculponeatins F-I (1-4), together with six known compounds, sculponeatin E (5), epi-nodosin (6), epi-nodosinol (7), Enmein (8), and macrocalyxoformins A and B (9 and 10), were isolated from the leaves of Isodon sculponeata. Also obtained were ursolic acid, 2alpha,3beta-dihydroxy-urs-12-en-28-oic acid, 2alpha,3beta,19alpha-trihydroxy-urs-12-en-28-oic acid, beta-sitosterol, daucosterol, quercetin, pedalitin, rosmarinic acid, caffeic acid and ethyl caffeic acid. Their structures were determined by spectral methods (1D-, 2D-NMR and MS). Some diterpenoids were tested for their cytotoxicity to inhibit three kinds of human tumor cells K562, A549 and T24. Compounds 3, 4, 6, 8, and 10 showed significant inhibitory effect toward K562 with IC(50) values ranging from 3.2 microg/ml to 8.2 microg/ml, while 3 and 6 exhibited potent antitumor activity against T24, but none exhibited cytotoxicity toward the cells of A549.
