Microcalorimetric study on the bacteriostatic activity of isoquinoline alkaloids

The isoquinoline alkaloids were isolated from traditional Chinese drugs of Phellodendri Cortex, Radix Stephaniae Tetrandrae, Corydalis Yanhusuo and Corydalis Bungeana. The power-time curves of growth of E. coli at different concentrations of isoquinoline alkaloid at 37 degrees C were determined by a 2277 Thermal Activity Monitor. The rate constant of bacteriostastic activity was calculated. The relationship between growth rate constant and concentration was established. The optimum bacteriostastic concentration was determined. Experimental results have indicated that all the isoquinoline alkaloids isolated from the four kinds of traditional Chinese drugs have bacteriostastic activity and the order is Phellodendri Cortex > Radix Stephaniae Tetrandrae > Corydalis Yanhusuo > Corydalis Bungeana.

Integrated analysis of the transcriptome, metabolome and analgesic effect provide insight into potential applications of different parts of Lindera aggregata

Lindera aggregata (L. aggregata) is a wild shrub growing in the forests of Southeast Asia, whose main bioactive constituents are isoquinoline alkaloids. They are widely used in food and pharmaceutical industries. The studies on the metabolites and biosynthesis pathways in L. aggregata remain poorly understood. Nine isoquinoline alkaloid compounds were identified by UPLC Triple TOF-MS/MS in this study. Except for N-methyllaurotetanine, most isoquinoline alkaloid compounds were widely distributed in various parts of L. aggregata and accumulated preferentially in roots than in leaves. Transcriptome data showed that several isoquinoline alkaloid biosynthetic genes, such as TyrAT, PPO, TDC, and SOMT, were identified to play important roles in generating differential metabolites in roots and leaves of L. aggregata. Concentration-dependent analgesic effects and toxic effects of them were demonstrated in zebrafish experiments, and the overall ranking was JRAL > TRAL > LAL. The results of this study would provide useful information for the synthesis mechanisms of isoquinoline alkaloids in L. aggregata, and provide valuable information for the application of traditional non-medicinal parts of L. aggregata in food and pharmaceutical industries.

Novel calamitic liquid crystals having an electron-deficient isoquino[8,7-h]isoquinoline moiety as a core, 2,8-didecylisoquino[8,7-h]isoquinoline (10-IQIQ-10) and 2,8-didodecylisoquino[8,7-h]isoquinoline (12-IQIQ-12), were prepared, and their phase transition behaviors, HOMO and LUMO levels, and charge carrier transport properties were investigated. 12-IQIQ-12 showed a highly ordered smectic H phase at around 140 to 150 degrees C and a low-lying LUMO level of -3.33 eV. Time-of-flight measurements revealed field-independent ambipolar transport characterized by mobility on the order of 10(-4) cm(2) V-1 s(-1) at the highly ordered smectic phase.

Preparative separation of isoquinoline alkaloids from Corydalis impatiens using a middle-pressure chromatogram isolated gel column coupled with two-dimensional liquid chromatography

We established a two-dimensional strong cation exchange/reversed-phase liquid chromatography protocol to isolate and purify isoquinoline alkaloids from Corydalis impatiens. Isoquinoline alkaloids were first enriched from a C. impatiens extract in which liposoluble components were removed using a medium-pressure chromatographic tower containing middle chromatogram isolated gel. A strong cation exchange column was employed to separate and obtain 30 fractions. We chose fractions 22-29 for reversed-phase liquid chromatography purification using characteristic isoquinoline alkaloid ultraviolet absorption spectra. Several isoquinoline alkaloid fractions (22-29) were further separated, and those of low resolution were isolated via two-dimensional liquid chromatography in the orthogonal plane. A total of eight novel isoquinoline alkaloids with characteristic ultraviolet spectra were obtained from C. impatiens. We thus demonstrate the benefits of off-line two-dimensional strong cation exchange/reversed-phase liquid chromatography to isolate isoquinoline alkaloids from C. impatiens.
