The DNA intercalating, ellipticine analog drug, 5,11-dimethyl-5H-indol[2,3-b]quinoline, is able to stabilize in vitro the topoisomerase II-DNA cleavable complex and to induce DNA breaks in BPV I episome in rat fibroblasts. Cytotoxicity studies with DC3F cells resistant to ellipticine strongly suggest that topoisomerase II is a cellular target involved in the mechanism of cytotoxic action of this carboline derivative.

Manzamine A, a natural compound derived from various sponge genera, features a β-carboline structure and exhibits a range of biological activities, including anti-inflammatory and antimalarial effects. Its potential as an anticancer agent has been explored in several tumor models, both in vitro and in vivo, showing effects through mechanisms such as cytotoxicity, regulation of the cell cycle, inhibition of cell migration, epithelial-to-mesenchymal transition (EMT), autophagy, and apoptosis through multi-target interactions of E2F transcriptional factors, ribosomal S6 kinases, androgen receptor (AR), SIX1, GSK-3β, V-ATPase, and p53/p21/p27 cascades. This systematic review evaluates existing literature on the potential application of this marine alkaloid as a novel cancer therapy, highlighting its promising ability to inhibit cancer cell growth while causing minimal side effects.

The construction of complex molecules under metal-free conditions multiple bond-forming steps in a cascade manner is highly desirable. Herein, we have developed an HFIP-alone promoted aminomethylation and intramolecular cyclization of allenamides, providing biologically relevant tetrahydro-β-carboline derivatives embedded with an allylic amine functionality. The metal-free protocol provided the desired tetrahydro-β-carboline derivatives under mild conditions.

β-Carbolines (βCs) are bioactive compounds present in foods and biological systems. This work describes the identification, occurrence, and mechanism of formation of 1-acetyl-β-carbolines (1-acetyl-βCs) that result from the reaction of l-tryptophan with the α-dicarbonyl compound methylglyoxal. Two β-carbolines are characterized as 1-acetyl-β-carboline (AβC) and 1-acetyl-β-carboline-3-carboxylic acid (AβC-COOH).

β-carbolines (βCs) represent a large family of bioactive alkaloids, including norharmane and normelinonine F, known for their diverse pharmacological activities. The effects of these alkaloids may depend, among other factors, on their delivery, accumulation in different subcellular compartments, and interactions with biomacromolecules such as serum albumins. In this study, we investigated the pH dependence of the interactions between bovine serum albumin (BSA) and four βCs (norharmane, normelinonine F, and their corresponding N(9)-methyl derivatives) using UV-vis and fluorescence spectroscopy, combined with multivariate analysis and molecular docking.

Harmaline as a natural compound possessed a wide range of pharmacological activities. In this study, 22 novel harmaline-based derivatives were synthesized and screened for in vitro anti-proliferation activity against three cancer cell lines, HCT116, MCF7, and MGC803. The modification site was at the position N-9 of harmaline.
