Leishmanicidal Activity of Nine Novel Flavonoids from Delphinium staphisagria
OBJECTIVES To evaluate the in vitro leishmanicidal activity of nine flavonoid derivatives from Delphinium staphisagria against L. infantum and L. braziliensis. DESIGN AND METHODS The in vitro activity of compounds 1-9 was assayed on extracellular promastigote and axenic amastigote forms and on intracellular amastigote forms of the parasites. Infectivity and cytotoxicity tests were carried on ...
متن کاملToxic Alkaloid Concentrations in Delphinium nuttallianum, Delphinium andersonii, and Delphinium geyeri in the Intermountain Region
Low larkspurs (Delphinium nuttalliunum Pritz., Delphinium andersonii Gray) and plains larkspur (Delphinium geyeri Greene) often poison cattle grazing on western North American rangelands. The dominant toxic alkaloid in larkspur is methyllycaconitine (MLA); other very toxic alkaloids in low and plains larkspurs are nudicauline and geyerline. Toxic alkaloid concentrations in larkspur near or abov...
متن کاملDelphinium L. Subgen. Delphinium: origin and evolutionary trends
BLANCHE, C. (1990) Delphinium L. subgen. Delphinium: origin and evolutionary trends. Collect. Bot. (Barcelona), 19: 75-95. The advanced features of Delphinium L. subgen. Delphinium (annual taxa) are compared with those of subgen. Delphinastrum (DC.) Wang and subgen. Oligophyllon Dimitrova (perennial taxa). Flower morphology shows a functional interchange between lateral petals and upper petals,...
متن کاملDiterpenoid Alkaloids from Delphinium ajacis
Five new diterpenoid alkaloids, ajacisines A–E (1–5), were isolated from Delphinium ajacis, along with seven known alkaloids (6–12). On the basis of their spectral data (IR, UV, HR‐ESI‐MS, 1D and 2D NMR) and chemical properties, the structures of compounds 1–12 were identified. All isolated compounds were evaluated for their in vitro antiviral activities against respiratory syncytial virus, and...
متن کاملEffects of Delphinium alkaloids on neuromuscular transmission.
The Delphinium alkaloids methyllycaconitine (MLA), nudicauline, 14-deacetylnudicauline (14-DN), barbinine, and deltaline were investigated for their effects on neuromuscular transmission in lizards. The substituent at C14 provides the only structural difference among the alkaloids MLA, nudicauline, 14-DN, and barbinine. Deltaline lacks the N-(methylsuccinyl)anthranilic acid at C18 common to the...
