Benzazolo[3,2-a]quinolium salts (BQS) are cationic quaternary alkaloids with similar structure to the anticancer agent ellipticine. This study describes synthesis and screen, at experimental concentration of 10 mM, utilizing 60 cell line anti-cancer screening two BQS, namely, 7-benzyl-3- aminobenzimidazo[3,2-a]quinolinium chloride (ABQ-48: NSC D-763307) corresponding nitrobenzimidazo[3,2-a]quinolinium (NBQ 48: D-763303). Compound ABQ-48: D-763307 was also screened in 5-dose NCI panel. These...
In continuation of our chemical investigation the Caribbean sea plume Pseudopterogorgia americana from Puerto Rico, six previously undescribed guaiane lactones were recently discovered. The structures metabolites 1−6, including their relative stereochemistry, established largely by NMR. constitution and configurations 1 confirmed a single-crystal X-ray diffraction study. some instances, new compounds generated NMR spectra characterized an abundance broad signals very low intensity,...

Abstract Several hitherto unknown thiazolo[3,2‐ a ]quinolinium salts derivatives were prepared and characterized. Two‐dimensional high field nmr methods employed to make complete assignments of the proton carbon spectra for these compounds.
