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.

Acetogenic isoquinoline alkaloids. Part 117 – First total synthesis of dioncophylline B, a 7,6 ‘-coupled naphthylisoquinoline alkaloid

The total synthesis of dioncophylline B (2), a naphthyl isoquinoline alkaloid with the rare 7,6′-coupling type and high antimalarial and fungicidal activities, is described. The key step of this convergent synthesis is the regioselective intermolecular biaryl coupling of its appropriately modified naphthalene and isoquinoline moieties, with MOM-functionalized oxygen substituents next to the coupling sites: The naphthalene moiety is activated by a directed ortho-metalation –> stannylation procedure, while the isoquinoline part is metalated and then brominated ortho to the MOM-protected oxygen function, thus allowing a Stille coupling to connect the two parts. The work constitutes the first synthesis of any 7,6’-coupled naphthylisoquinoline alkaloid.

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.

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.
