Four new diterpenoids from Isodon eriocalyx var. laxiflora

Four new diterpenoids, laxiflorins S-V (1–4), bearing four different types, and one known compound, laxiflorin O (5), were isolated from Isodon eriocalyx var. laxiflora. Compound 1 was the first example of ent-kauranoids bearing a unique C24 carbon framework and compound 4 was the first example of 3,4-seco-ent-abietane diterpenoids from the Isodon genus. Their structures were...

Isorosthornins A-C, new ent-kaurane diterpenoids from Isodon rosthornii

Three new ent-kauranoids, isorosthornins A-C (1–3), and a new natural product, dihydroponicidin (4), together with five known ones were isolated from the aerial parts of Isodon rosthornii. The structures were determined by means of extensive spectroscopic analysis. All diterpenoids isolated were evaluated for their cytotoxicity against HL-60, SMMC-7721, A-549, MCF-7, and SW480...
