Reaction of enamino pyrrolidide and piperidide of 2,2-dimethyl-1,2,3,4-tetrahydrobenz[f]isoquinoline series with ninhydrin

Interaction of (4Z)-2,2-dimethyl-4-(2-oxo-2-pyrrolidin-1-ylethylidene)-1,2,3,4-tetrahydrobenz[f]isoquinoline with ninhydrin leads to annulation of an indeno[1,2-b]pyrrole ring. An analogous product is formed by replacing of the pyrrolidine ring with the piperidine ring. Further heating of the obtained glycol in the presence of AcOH leads to rearrangement with the formation of benz[f]isochromeno-[4′,3′:4,5]pyrrolo[2,1-a]isoquinoline hexacyclic system.

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.

ATMOSPHERIC AND INDOOR CHEMISTRY OF GAS-PHASE INDOLE, QUINOLINE, AND ISOQUINOLINE

The gas-phase chemistry of the nitrogen-containing organic compounds indole, quinoline and isoquinoline, which are present in environmental tobacco smoke, has been investigated. No photolysis of these nitrogen heterocycles was observed under indoor ”white” fluorescent lighting conditions. Rate constants for the gas-phase reactions of these compounds with OH radicals, NO3 radicals, NO2, and O-3 were measured, and the rate constants obtained (in cm(3) molecule(-1) s(-1) units) were: for reaction with the OH radical: indole, (1.54+/-0.35)x10(-10); quinoline, (1.16+/-0.55)x10(-11); isoquinoline, (8.5+/-3.6)x10(-12); for reaction with the NO3 radical: indole, (1.3+/-0.5)x10(-10) for reaction with NO2: indole, < 2 x 10(-19); quinoline, < 1.6 x 10(-20) isoquinoline, < 1.1 x 10(-19) and for reaction with O-3: indole, (4.9+/-1.8)x10(-17); quinoline, < 1.0x10(-19); and isoquinoline, < 1.1x10(-19). Evidence was obtained that quinoline reacts with gas-phase nitric acid and this is also expected to be the case for isoquinoline. These data indicate that in indoor environments, quinoline and isoquinoline will be largely removed by air exchange unless gas-phase nitric acid is present, while indole will be removed by chemical reaction if NO3 radicals are present at part-per-trillion levels. Products of the O-3 and OH radical reactions with indole have been studied and the possible O-3 reaction mechanism is discussed. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 17557-76-5 help many people in the next few years. Category: isoquinoline.

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.
