AI Article Synopsis

  • The study investigated the phytochemicals in the methanol extract of Clausena lansium, identifying nine carbazole alkaloids, including two new ones called claulansiums A and B.
  • The new compounds were characterized using advanced techniques like MS, NMR, IR, and UV, while known compounds were confirmed by comparing data with existing literature.
  • The isolated compounds were tested for cytotoxic activity against A549 and Hela cancer cell lines, with compounds 2-6 showing significant cytotoxic effects at varying concentrations.

Article Abstract

The present study carried out a phytochemical investigation of the methanol extract of the branches and leaves of Clausena lansium and afforded nine carbazole alkaloids (compounds 1-9) including two new carbazole alkaloids, claulansiums A and B (compounds 1 and 2). The new compounds were elucidated on the basis of extensive spectroscopic data (MS, NMR, IR, and UV) and the known compounds were identified by comparing spectroscopic data with those reported in literature. All the isolated compounds were tested for their cytotoxic activity against A549 and Hela cancer cell lines. Our results showed that compounds 2-6 exhibited varying degrees of cytotoxicity to cancer cells, with IC values ranging from 8.67 to 98.89 μmol·L.

Owning to the versatile nature in participation of Diels-Alder (D-A) reactions, the development of efficient approaches to generate active ortho-quinodimethanes (o-QDMs) has gained much attention. However, a catalytic method involving coupling of two readily accessible components to construct o-QDMs is lacking. Herein, we describe a palladium carbene migratory insertion enabled dearomative C(sp)-H activation to form active o-QDM species through the cross-coupling of N-tosylhydrazones with aryl halides.

The plants of Rutaceae, with wide distribution in China, have a long history of medicinal use. They contain a wide variety of alkaloids, which include isoquinolines, quinolines, acridones, carbazoles, and indoles. Pharmacological studies have shown that most of these alkaloids have antitumor, anti-inflammatory, antiviral, antidiabetic and other activities.

Antisense oligonucleotides as a targeted therapeutic approach in model of acute myeloid leukemia.

Background: The genetic and epigenetic alterations observed in acute myeloid leukemia (AML) contribute to its heterogeneity, influencing disease progression response to therapy, and patient outcomes. The use of antisense oligonucleotides (ASOs) technology allows for the design of oligonucleotide inhibitors based on gene sequence information alone, enabling precise targeting of key molecular pathways or specific genes implicated in AML.

Methods And Results: Midostaurin, a FLT3 specific inhibitor and ASOs targeting particular genes, exons, or mutations was conducted using AML models.

Accumulating evidence suggests that phenotype switching of cancer cells is essential for therapeutic resistance. However, the immunological characteristics of drug-induced phenotype-switching melanoma cells (PSMCs) are unknown. We investigated PSMC elimination by host immunity using hyperdifferentiated melanoma model cells derived from murine B16F10 melanoma cells.

We report the construction of unsymmetrical dimeric carbazoles and π-extended bis carbazoles (having an aryl ring spacer) via the C-H functionalization route. Generally, oxidative coupling and traditional cross-coupling reactions have been used to construct bis- and π-extended carbazoles. Natural bis carbazole alkaloids and synthetic dimeric carbazoles are important molecules in medicinal, materials chemistry research.
