Abstract
Herein, we report the synthesis of new compounds with demonstrated anticancer properties based on the 2,3,4,9-tetrahydro-1H-carbazole scaffold. The Fischer indolization method was used to close the heterocyclic motif. The synthesis method's scope and limitations were thoroughly assessed through a series of experiments. Biological assays revealed that two thioamide compounds exhibited significant anticancer activity against MCF-7, HTC116, and A596 cell lines. Comprehensive in vitro profiling included evaluation of cell cytotoxicity, morphological alterations, colony formation and cell adhesion in 3D cultures, cell cycle analysis, DNA damage induction, impact on mitochondria, and apoptosis. Ex ovo studies further demonstrated these compounds' potential to inhibit angiogenic processes. Our results indicate that the newly developed compounds activate processes leading to DNA damage and disruption of mitochondrial function.

[PMID: 39134110 DOI: 10.1016/j.phytochem.2024.114245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Revised: 08/07/2024] [Accepted: 08/08/2024] [Indexed: 08/26/2024]
Abstract
Kopsileuconines A-D (1-4), four monoterpenoid bisindole alkaloids with unprecedented skeletons, along with their biosynthetically related precursors (5-8) were isolated from the roots of Kopsia hainanensis. Compound 1 possessed an undescribed C-6-C-5' dimerization pattern of aspidofractinine-type alkaloids. Compounds 2-4 were rhazinilam-kopsine (2) and rhazinilam-aspidofractinine type (3 and 4) bisindole alkaloids with undescribed skeletons, respectively. Their structures with absolute configurations were fully accomplished by extensive spectroscopic analysis, quantum-chemical calculations, and X-ray crystallography. A plausible biosynthetic pathway for 1-4 was proposed. Compound 2 exhibited a significant inhibitory effect against human lung cancer cell lines PC9 (EGFR mutant), with an IC50 value of 15.07 ± 1.19 μM.

Abstract
An efficient approach to access chiral N-α indole substituted pyrrolidine and piperidine skeletons has been developed through a AgSbF6-catalyzed N-α aza-Friedel-Crafts alkylation of N,O-acetals 6a, 6b, 9, and 11a-11d with indoles. As a result, a series of 2,3-trans N-α indole substituted pyrrolidines 8a-8x and piperidines 10a-10j were prepared in moderate to excellent yields and with excellent diastereoselectivities (dr up to 99 : 1). Moreover, several 2,5-cis-N-α indole substituted pyrrolidine derivatives 12a-12k were synthesized according to this strategy with moderate to good yields and diastereoselectivities (dr up to 99 : 1).

Abstract
Nitrogen stereocenters are common chiral units in natural products, pharmaceuticals, and chiral catalysts. However, their research has lagged largely behind, compared with carbon stereocenters and other heteroatom stereocenters. Herein, we report an efficient method for the catalytic asymmetric synthesis of Tröger's base analogues with nitrogen stereocenters via palladium catalysis and home-developed GF-Phos. It allows rapid construction of a new rigid cleft-like structure with both a C- and a N-stereogenic center in high efficiency and selectivity. A variety of applications as a chiral organocatalyst and metallic catalyst precursors were demonstrated. Furthermore, DFT calculations suggest that the NH···O hydrogen bonding and weak interaction between the substrate and ligand are crucial for the excellent enantioselectivity control.

Abstract
Kopsia belongs to the family Apocynaceae, which was originally classified as a genus in 1823. Kopsia consists of medicinal plants that can be traditionally used to treat rheumatoid arthritis, pharyngitis, tonsillitis, and dropsy. More than one hundred and twenty-five publications have been documented relating to the phytochemical and pharmacological results, but a systematic review is not available. The goal of this study is to compile almost all of the secondary metabolites from the plants of genus Kopsia, as well as the coverage of their pharmacological research. The document findings were conducted via reliable sources, including Web of Science, Sci-Finder, Science Direct, PubMed, Google Scholar, and publishers, while four words "Kopsia", "monoterpene alkaloids", "Phytochemistry" and "Pharmacology" are key factors to search for references. Most Kopsia secondary metabolites were collected. A total of four hundred and seventy-two, including four hundred and sixty-six monoterpene alkaloids, five triterpenoids, and one sterol, were summarized, along with their resource. Kopsia monoterpene alkaloids presented in various skeletons, but aspidofractinines, eburnamines, and chanofruticosinates are the three major backbones. Mersinines and pauciflorines are new chemical classes of monoterpene alkaloids. With the rich content of monoterpene alkaloids, Kopsia constituents were also the main objects in pharmacological studies since the plant extracts and isolated compounds were proposed for anti-microbial, anti-inflammatory, anti-allergic, anti-diabetic, anti-manic, anti-nociceptive, acetylcholinesterase (AChE) inhibitory, cardiovascular, and vasorelaxant activities, especially cytotoxicity.

Abstract
Metal-catalyzed asymmetric allylic substitution (AAS) reaction is one of the most synthetically useful reactions catalyzed by metal complexes for the formation of carbon-carbon and carbon-heteroatom bonds. It comprises the substitution of allylic substrates with a wide range of nucleophiles or SN 2'-type allylic substitution, which results in the formation of the above-mentioned bonds with high levels of enantioselective induction. AAS reaction tolerates a broad range of functional groups, thus has been successfully applied in the asymmetric synthesis of a wide range of optically pure compounds. This reaction has been extensively used in the total synthesis of several complex molecules, especially natural products. In this review, we try to highlight the applications of metal (Pd, Ir, Mo, or Cu)-catalyzed AAS reaction in the total synthesis of the biologically active natural products, as a key step, updating the subject from 2003 till date.

Abstract
The ethanol extract of the twigs and leaves of Kopsia hainanensis afforded six new aspidofractinine alkaloids, kopsiahainanins A-F (1-6), among which alkaloids 1 and 2 possessed a lactone bridge with novel regiochemistry. The structures of the isolated compounds were established based on 1D and 2D (1H1H COSY, HMQC, and HMBC) NMR spectroscopy, in addition to high resolution mass spectrometry. The isolated compounds were tested in vitro for cytotoxic activity against seven tumor cell lines and antibacterial activities against two Gram-positive bacteria and five Gram-negative bacteria. As a result, alkaloids 1 and 2 exhibited cytotoxic activities (IC50 values <20 μM) against all tested tumor cell lines and significant antibacterial properties (MIC values from 0.12 to 0.26 mM).

Abstract
Enantioselective Pd-catalyzed allylic alkylations of dihydropyrido[1,2-a]indolone (DHPI) substrates were used to construct the C20-quaternary stereocenters of multiple monoterpene indole alkaloids. Stereodivergent Pictet-Spengler and Bischler-Napieralski cyclization/reduction cascades furnish the cis- and trans-fused azadecalin subunits present in Aspidosperma and Kopsia alkaloids, respectively, en route to highly efficient syntheses of (+)-limaspermidine and (+)-kopsihainanine A.

Abstract
Five new aspidofractinine-type alkaloids, kopsiahainins A-E (1-5), were isolated from a 80% EtOH extract of the leaves and stems of Kopsia hainanensis. Structural elucidation of all the compounds were performed by spectral methods such as 1D- and 2D-NMR, IR, UV, and HR-ESI-MS. Alkaloids 3 and 4 exhibited some cytotoxic activity against all of six tested tumor cell lines (BGC-823, HepG2, MCF-7, SGC-7901, SK-MEL-2, and SK-OV-3) with IC50 values of 7.3-9.5μM and 9.2-10.6μM, respectively.

Abstract
Three new indole alkaloids, named kopsioffines A-C (1-3), possessing relatively novel ten-membered lactam ring, and one known compound (11,12-demethoxy-16-deoxypauciflorine, 4) were isolated from the leaves and stems of Kopsia officinalis. Their structures were elucidated by means of spectroscopic methods. The absolute configuration of 1 was determined by calculated electronic circular dichroism data. The hypothetical biosynthetic pathway of 1 was postulated. All these isolates were evaluated for their inhibitory effects on α-glucosidase. None of them showed activity with IC50 far beyond 50μM.

Abstract
Perhydroquinoline 4, the product of a Raney-cobalt mediated reductive cyclization reaction, was readily converted into the cis-ring-fused perhydroquinoline 15 that could be epimerized to its trans-fused counterpart 2 on sequential treatment with iodosylbenzene then sodium borohydride. Tetracycle 2 is an advanced intermediate associated with a recently reported total synthesis of the alkaloid kopsihainanine A (1).

Abstract
The formal synthesis of (+)-kopsihainanine A has been achieved via stereoselective reduction of tetracyclic iminium ion intermediates (24). However, attempts to synthesize (+)-limaspermidine by reduction of the same tetracyclic iminium ion intermediates have failed. The synthesis features a Suzuki cross-coupling reaction, a cyclization reaction mediated by trifluoromethanesulfonic anhydride, and stereoselective reduction of an iminium ion.
