The given review provides data on the new sesquiterpene lactones with unusual structure isolated from various natural sources, e.g. fungi, plants, marine growth; about their spread, biological activity, and the presumed biogenetic pathway of their formation. An attempt was made to biologically justify a wide structural formation variety of new sesquiterpene lactones with the unique structure.

Alantolactone and isoalantolactone are two isomeric sesquiterpene lactones that were isolated from Innula recemosa. Here, we are used for the semisynthesis of novel isoxazolidine hybrids of alantolactone and isoalantolactone through a two-step process: nitrone synthesis followed by nitrone 1,3-dipolar cycloaddition. The formation of the cycloadduct was well characterized via modern spectroscopic techniques such as HRMS, H NMR, C NMR, DEPT-90, DEPT-135, and 2D NMR.

The potential sesquiterpene lactone groups from the Vernonia genus; namely vernolide-A, vernolide-B, and vernodalin, have been reported for anticancer effects by downregulating cancer promoter proteins. Nevertheless, prior investigations have failed to identify the target proteins that are associated with the compounds' actions. Subsequently, the present investigation attempts to identify the target proteins associated with cancer.

Six undescribed sesquiterpene lactones (1-6) and fifteen known compounds (7-21) were isolated from Seriphidium transiliense. The chemical structures were determined by extensive NMR spectroscopic data, HRESIMS, ECD and X-ray diffraction. Among the known compounds, twelve known compounds were isolated for the first time from this plant, including taurine (9), 11-epitaurin (10), α-santonin (11), artesin (13), 11-epiartesin (14), 1α-hydroxy-3β-acetoxyeudesm-4-en-6β, 7α, 11βH-12, 6-olide (15), 1α-hydroxy-3β-acetoxyeudesm-4-en-6β, 7α, 11αH-12, 6-olide (16), artegallin (17), 8α-hydroxytaurin (18), 8α-acetoxytaurine (19), methyl-4α-hydroxy-11(13)-eudesmen-12-oatesaniculamoid D (20), and saniculamoid D (21).

Regulated cell death (RCD) is a type of cell death modulated by specific signal transduction pathways. Currently, known RCD types include apoptosis, autophagy, ferroptosis, necroptosis, cuproptosis, pyroptosis, and NETosis. Mutations in cancer cells may prevent the RCD pathway; therefore, targeting RCD in tumors has become a promising therapeutic approach.
