Design, synthesis, and testing of an isoquinoline-3-carboxylic-based novel anti-tumor lead

Compound 6, a novel isoquinoline comprising two isoquinoline-3-carboxylic acids and a benzoic acid conjugated together using tris(2-aminoethyl) amine, was synthesized and tested for anti-tumor activity. In vivo evaluations found 6 to be well tolerated, of high therapeutic efficacy and of low systemic toxicity, at effective doses. The results suggest 6 to be a promising lead for future study, and the use of multiple isoquinoline-3-carboxylic acid moieties as pharmacophores in the same molecule to be a useful strategy for the design of anti-tumor drugs.

Isoquinoline alkaloids: a N-15 NMR and x-ray study. Part 2

Continuing our systematic N-15 NMR study of isoquinoline alkaloids, we report a contribution extending our previous paper. The N-15 NMR chemical shifts and N-15,H-1 long-range coupling pathways of tertiary and quaternary isoquinoline alkaloids of several constitutional types are presented. The selected compounds belong to the protoberberine, proaporphine, pavinane, rhoeadine and phtalideisoquinoline classes of alkaloids and were investigated by gradient-selected inverse-detected multiple bond correlation experiments (GHMBC and GSQMBC). In addition, x-ray data and the principal geometric parameters of stylopine, mecambridine, norchelerythrine, isothebaine and mecambrine are reported and discussed.

DESCRIPTION OF BACTERIA ABLE TO DEGRADE ISOQUINOLINE IN PURE CULTURE

Isoquinoline is a nitrogen heterocyclic compound that is associated with coal- and oil-derived wastes. Four strains of bacteria able to degrade isoquinoline in pure culture were isolated from sites known to be contaminated with oil. Isoquinoline was used as the sole source of carbon and nitrogen by these isolates. Isoquinoline was initially transformed to 1-hydroxyisoquinoline, which accumulated in the broth culture, and then disappeared. The four strains isolated were Gram negative, aerobic, rod-shaped bacteria with polar flagella. The strains have been presumptively identified as members of the family Comamonadaceae.
