Analysis of the Impact of Isoquinoline Alkaloids, Derived from Macleaya cordata Extract, on the Development and Innate Immune Response in Swine and Poultry

Medicinal extract has been chronicled extensively in traditional Chinese medicine. Isoquinoline alkaloids, extract of Macleaya cordata (Willd.) R. Br., have been used as feed additive in both swine and poultry. Dietary supplementation with isoquinoline alkaloids increases feed intake and weight gain. In addition, recent researches have demonstrated that isoquinoline alkaloids can regulate metabolic processes, innate immune system, and digestive functioning in animals. This review summarizes the latest scientific researches on isoquinoline alkaloids which are extracted from Macleaya cordata (Willd.) R. Br. This review specifically focuses on its role as a feed supplement and its associated impact on growth performance and innate immune system, as well as its capacity to act as a substitute for oral antibiotics.

Force field and assignment of the vibrational spectra of quinoline and isoquinoline – An ab initio study

The force field and vibrational spectra of quinoline and isoquinoline with Cs symmetry are studied at Hartree Fock level of theory using 6-31G** basis set. The scaled non-redundant local force constants and the corresponding scale factors obtained after fitting the ab initio vibrational frequencies of quinoline to the experimental ones are presented. The scale factors are transferred to predict the fundamentals of isoquinoline. The predicted numbers agree well with the experimental numbers. The force fields and vibrational spectra of naphthalene, quinoline and isoquinoline reveal that they are structurally similar.

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.

Antimicrobially Active Isoquinoline Alkaloids from Litsea cubeba

Bioassay-guided fractionation of the alkaloidal extract of the aerial part of Litsea cubeba led to the isolation of two new isoquinoline alkaloids, (+)-N-(methoxycarbonyl)-N-norboldine (1) and (+)-isoboldine beta-N-oxide (2), together with 11 known analogues (3-13). Their structures were established by extensive spectroscopic techniques and by comparing spectroscopic data with those in the literature. Compounds 1 and 4 showed antimicrobial activities. This is the first report on the presence of compounds 1, 2, 6, 8, 9, 11, and 12 in this plant and on the antimicrobial activities of 1 and 4. The bioactivities of isoquinoline alkaloids are also at least partly responsible for the pharmacological function of the folk medicinal plant Litsea cubeba.
