Total Syntheses of Menisporphine and Daurioxoisoporphine C Enabled by Photoredox-Catalyzed Direct C-H Arylation of Isoquinoline with Aryldiazonium Salt

Isoquinoline alkaloids are attractive natural products due to their diverse chemical structures as well as remarkable bioactivities. Herein, we report the concise total syntheses of two isoquinoline alkaloids, menisporphine and daurioxoisoporphine C, through a mild and efficient photoredox-catalyzed direct C-H arylation of isoquinoline core with aryldiazonium salt. This new strategy is complementary to the conventional isoquinoline synthesis and would provide us a useful means to achieve a more convergent and flexible approach to access diverse isoquinoline structures.

Two new aminoethylstilbene isoquinoline alkaloids denoted litsine B (1) and Litsine C (2) were isolated from an ethanol extract from the root bark of Litsea glutinosa. The structures of the new chemical entities were established using 1D and 2D NMR spectroscopy in combination with high resolution mass spectrometry. Both compounds were tested for their effect on glucose consumption in HepG2 cells at different concentrations. The results showed that compound 2 significantly increased the glucose uptake.

CYP719A subfamily of cytochrome P450 oxygenases and isoquinoline alkaloid biosynthesis in Eschscholzia californica

Eschscholzia californica produces various types of isoquinoline alkaloids. The structural diversity of these chemicals is often due to cytochrome P450 ( P450) activities. Members of the CYP719A subfamily, which are found only in isoquinoline alkaloid-producing plant species, catalyze methylenedioxy bridge-forming reactions. In this study, we isolated four kinds of CYP719A genes from E. californica to characterize their functions. These four cDNAs encoded amino acid sequences that were highly homologous to Coptis japonica CYP719A1 and E. californica CYP719A2 and CYP719A3, which suggested that these gene products may be involved in isoquinoline alkaloid biosynthesis in E. californica, especially in methylenedioxy bridge-forming reactions. Expression analysis of these genes showed that two genes (CYP719A9 and CYP719A11) were preferentially expressed in plant leaf, where pavine-type alkaloids accumulate, whereas the other two showed higher expression in root than in other tissues. They were suggested to have distinct physiological functions in isoquinoline alkaloid biosynthesis. Enzyme assay analysis using recombinant proteins expressed in yeast showed that CYP719A5 had cheilanthifoline synthase activity, which was expected based on the similarity of its primary structure to that of Argemone mexicana cheilanthifoline synthase ( deposited at DDBJ/GenBank (TM)/EMBL). In addition, enzyme assay analysis of recombinant CYP719A9 suggested that it has methylenedioxy bridge-forming activity toward (R, S)-reticuline. CYP719A9 might be involved in the biosynthesis of pavine- and/or simple benzylisoquinoline-type alkaloids, which have a methylenedioxy bridge in an isoquinoline ring, in E. californica leaf.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 30433-91-1. Name: 2-(Thiophen-2-yl)ethanamine.
