Five new ent-abietane diterpenoids, ent-abierubesins A-E (1-5), and two new ent-kauranoids, hubeirubesins A and B (6, 7), together with three known diterpenoids (8-10), were isolated from the aerial parts of Isodon rubescens. Their structures were identified by means of extensive spectroscopic analysis, and the absolute stereochemistry of 1 was determined by single-crystal X-ray diffraction experiment.

Seven compounds(1-7) were isolated from Isodon henryi through silica gel, Sephadex LH-20, ODS, MCI column chromatography and semi-preparative HPLC. Their structures were identified as isogallicacid(1), caffeic acid(2), syringic acid(3), protocatechuic acid(4), oresbiusin A(5), lophanthoside A(6), and 8-hydroxypinoresinol(7), by spectroscopic techniques including HR-MS, IR, UV, NMR, and ECD. Compound 1 was a new galloyl derivative.

Aberrant activation of the NLRP3 inflammasome contributes to the evolution of diverse inflammatory diseases. Inhibition of the NLRP3 inflammasome has been proven to be an effective treatment strategy for NLRP3-driven diseases. This study revealed that multiple natural diterpenes from Isodon plants can inhibit the NLRP3 inflammasome, among which Rosthornin B (Ros B) exhibited the best inhibitory effect, with an IC of 0.
