NSC‑631570 (Ukrain) is an aqueous extract of Chelidonium majus, a herbaceous perennial plant, one of two species in the genus Chelidonium, which has been demonstrated to selectively kill tumor cells without affecting non‑malignant cells. In the present study, the components of NSC‑631570 were examined by combined liquid chromatography/mass spectroscopy (LC‑MS) and the effects of NSC‑631570 on HNSCC cell lines, as well as primary cells, were analyzed with respect to growth, apoptosis, invasion, angiogenesis and gene expression. LC‑MS identified chelerythrine and allocryptopine as the major alkaloids of the extract.

Entering the body via surgical sites and colonizing the medical devices through formation of multi-layered biofilms leads to refractory and persistent device-related infections (DRIs). Staphylococci organized in biofilms are more tolerant to antibiotics and immune responses, and thus are difficult-to-treat.

If there is no pharmacological intervention, the parasites can cross the blood-brain barrier (BBB), inevitably leading to death of the patients. Previous investigation identified the quinolone amide GHQ168 as a promising lead compound having a nanomolar activity against T.

A bioassay-guided fractionation of a dichloromethane extract yielded the isolation of the essential anti-trypanosomal compounds of the plant. Seven sesquiterpene lactones (including Achillolide-A), two flavonoids, chrysosplenol-D and chrysosplenetine, and four alkamides (including pellitorine) were identified.
