Leucoridines A-D, cytotoxic Strychnos-Strychnos bisindole alkaloids from Leuconotis.
Four new bisindole alkaloids of the Strychnos-Strychnos type, leucoridines A-D (1-4), were isolated from the stem-bark extract of Leuconotis griffithii. Alkaloids 1-4 showed moderate cytotoxicity against drug-sensitive and vincristine-resistant human KB cells.

متن کاملDevelopment and validation of a TLC-densitometric method for the simultaneous quantitation of strychnine and brucine from Strychnos spp. and its formulations.
A simple, sensitive, and specific thin-layer chromatography densitometric method has been developed for the simultaneous quantitation of strychnine and brucine. These two marker compounds are quantitated in the seeds of Strychnos nux-vomica, Strychnos ignatii, and its formulations. The method involves densitometric evaluation of strychnine and brucine after resolving it by high-performance TLC ...
متن کاملAlkaloids of Strychnos dolichothyrsa Gilg ex Onochie et Hepper.
Three alkaloids of the stem bark of Strychnos dolichothyrsa Gilg ex Onochie et Hepper (Loganiaceae) were isolated and identified as caracurine V and its mono- and di-N-oxide by comparison with synthesized compounds. 13C-NMR was used to confirm the structure of the N-oxides. The muscle relaxant activity and the toxicity of the N-oxides were less than those of caracurine V.
