Efficient Synthesis of Isoquinoline and Its Derivatives: From Metal Catalysts to Catalyst-free Processes in Water

Isoquinolines constitute an important class of natural alkaloids, that demonstrate a wide range of biological activities. Therefore, development of new methods for efficient synthesis of isoquinoline and its derivatives has attracted considerable attention of chemists and pharmacologists over recent years. In this review the progress of isoquinoline synthesis that provides creative inspiration and expands novel ideas for researchers in this field is summarized.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 36476-78-5, in my other articles.

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.

A class of novel N-isoquinoline-3-carbonyl-L-amino acid benzylesters: Synthesis, anti-tumor evaluation and 3D QSAR analysis

Isoquinoline-3-carboxylic acid (2) was modified with amino acid benzylesters and 18 novel N-isoquinoline-3-carbonylamino acid benzylesters (3a-r) were provided. The IC50 values of 3a-r against the proliferation of HL-60 and Hela cells were less than 1 x 10(-8) M and 6 x 10(-7) M, respectively. On S180 mice model 100 mu mol/kg of 3a-r effectively inhibited the growth of the tumors. Using MFA based Cerius(2) QSAR module, two equations (r, 0.989 and 0.987) were established to correlate the structure with the in vitro and in vivo activities. The benefit of this modification was supported with both the in vitro membrane permeation test and the in vivo anti-tumor assay. The in vitro membrane permeability of N-isoquinoline-3-carbonyl-L-threonine benzylester (3n) and N-isoquinoline-3-carbonyl-L-leucine benzylester (3q) was 2.5 fold higher than that of 2, and the in vivo anti-tumor activity of 3n, q was 4.4-fold higher than that of 2.
