A detailed phytochemical investigation of a dichloromethane extract of the resinous exudates of the cushion bush plant (Leucophyta brownii) resulted in the isolation of the new 8,12-guaianolides leucophytalins A (5) and B (6), the new 1,10-seco-eudesmane leucophytalin C (10), six rare
Dynamin-related protein 1 (Drp1) is a newly discovered therapeutic target for tumor initiation, migration, proliferation, and chemosensitivity. Thus, therapeutic strategies that focus on targeting Drp1 and its related signaling pathway pave a new way to address the ineffectiveness of traditional
An extract from the entire Ixeris denticulata f. pinnatipartita plant afforded the guaianolide sesquiterpene lactone glucoside, 8 beta,15-dihydroxy-1(10),3,11(13)-guaiatrien-12,6-olide-15-O- glucopyranoside, along with the known flavonoids luteolin-7-O-glucoside and
Chloroform extracts of the underground parts of two Balkan endemic Laserpitium species, Laserpitium zernyi Hayek and Laserpitium ochridanum Micevski, were chemically investigated. Five unknown guaianolides from the class of slovanolides, of which four were additionally 2β-esterified, as well as two
Four new (1-4) and 13 known (5-17) sesquiterpene lactones along with two known diterpenes (18, 19) were isolated from the whole plant of Carpesium faberi. The new structures were elucidated by means of spectroscopic techniques and some chemical transformations to be
