Abstract
Numerous small molecules exert antitumor effects by interacting with DNA, thereby influencing processes, such as DNA replication, transcription, meiosis, and gene recombination. Benzophenanthridine and protoberberine alkaloids are known to bind DNA and exhibit many pharmacological activities. In this study, we conducted a comparative analysis of the interactions between these two classes of alkaloids with G-quadruplex (G4) DNA and double-stranded DNA (dsDNA). Protoberberine alkaloids showed a greater affinity for binding with G4s than with dsDNA, while benzophenanthridine alkaloids exhibited a significantly stronger binding capacity for dsDNA, especially in regions that are rich in AT base pairs. Benzophenanthridine alkaloids also exhibited much stronger toxicity to various cancer cells. Compared with protoberberine alkaloids, benzophenanthridine alkaloids displayed much stronger activity in inhibiting cellular DNA and RNA synthesis, arresting the cell cycle in the G2/M phase, inducing cell apoptosis, and leading to intracellular DNA damage. Given that dsDNA constitutes the predominant form of DNA within cells for the majority of the cell cycle, the significant antiproliferative activity of benzophenanthridine alkaloids could be attributed, in part, to their higher binding affinity for dsDNA, thereby exerting a more significant impact on cellular proliferation. These findings have valuable implications for understanding the biological activities of isoquinoline alkaloids and their antitumor applications.

Abstract
DNA-based logic circuits, encoding algorithms in DNA and processing information, are pushing the frontiers of molecular computers forward, owing to DNA's advantages of stability, accessibility, manipulability, and especially inherent biological significance and potential medical application. In recent years, numerous logic functions, from arithmetic to nonarithmetic, have been realized based on DNA. However, DNA can barely provide a detectable signal by itself, so that the DNA-based circuits depend on extrinsic signal actuators. The signal strategy of carrying out a response is becoming one of the design focuses in DNA-based logic circuit construction. Although work on sequence and structure design for DNA-based circuits has been well reviewed, the strategy on signal production lacks comprehensive summary. In this review, we focused on the latest designs of fluorescent output for DNA-based logic circuits. Several basic strategies are summarized and a few designs for developing multi-output systems are provided. Finally, some current difficulties and possible opportunities were also discussed.

Abstract
In the genus Macleaya, Macleaya cordata and Macleaya microcarpa have been recognized as traditional herbs that are primarily distributed in China, North America, and Europe and have a long history of medicinal usage. These herbs have been long valued and studied for detumescence, detoxification, and insecticidal effect. This review aims to provide comprehensive information on botanical, phytochemical, pharmacological, and toxicological studies on plants in the genus Macleaya. Plants from the genus of Macleaya provide a source of bioactive compounds, primarily alkaloids, with remarkable diversity and complex architectures, thereby having attracted attention from researchers. To date, 291 constituents have been identified and/or isolated from this group. These purified compounds and/or crude extract possess antitumor, anti-inflammatory, insecticidal, and antibacterial activities in addition to certain potential toxicities. Macleaya species hold potential for medicinal applications. However, despite the pharmacological studies on these plants, the mechanisms underlying the biological activities of active ingredients derived from Macleaya have not been thoroughly elucidated to date. Additionally, there is a need for research focusing on in vivo medical effects of Macleaya compounds and, eventually, for clinical trials.

Abstract
Activating KRAS mutations frequently occur in pancreatic, colorectal, and lung adenocarcinomas. While many attempts have been made to target oncogenic KRAS, no clinically useful therapies currently exist. Most efforts to target KRAS have focused on inhibiting the mutant protein; a less explored approach involves targeting KRAS at the transcriptional level. The promoter element of the KRAS gene contains a GC-rich nuclease hypersensitive site with three potential DNA secondary structure-forming regions. These are referred to as the Near-, Mid-, and Far-regions, on the basis of their proximity to the transcription start site. As a result of transcription-induced negative superhelicity, these regions can open up to form unique DNA secondary structures: G-quadruplexes on the G-rich strand and i-motifs on the C-rich strand. While the G-quadruplexes have been well characterized, the i-motifs have not been investigated as thoroughly. Here we show that the i-motif that forms in the C-rich Mid-region is the most stable and exists in a dynamic equilibrium with a hybrid i-motif/hairpin species and an unfolded hairpin species. The transcription factor heterogeneous nuclear ribonucleoprotein K (hnRNP K) was found to bind selectively to the i-motif species and to positively modulate KRAS transcription. Additionally, we identified a benzophenanthridine alkaloid that dissipates the hairpin species and destabilizes the interaction of hnRNP K with the Mid-region i-motif. This same compound stabilizes the three existing KRAS G-quadruplexes. The combined effect of the compound on the Mid-region i-motif and the G-quadruplexes leads to downregulation of KRAS gene expression. This dual i-motif/G-quadruplex-interactive compound presents a new mechanism to modulate gene expression.

Abstract
Tryptanthrin is one of the most important members of indoloquinoline alkaloids. We obtained this alkaloid from Isatis. Two novel FeII and CoII complexes of tryptanthrin were first synthesized. Single-crystal X-ray diffraction analyses show that these complexes display distorted four-coordinated tetrahedron geometry via two heterocyclic nitrogen and oxygen atoms from tryptanthrin ligand. Binding with G-quadruplex DNA properties revealed that both complexes were found to exhibit significant interaction with G-quadruplex DNA. This study may potentially serve as the basis of future rational design of metal-based drugs from natural products that target the G-quadruplex DNA.

Abstract
G-quadruplex structures can be formed at the single-stranded overhang of telomeric DNA, and ligands able to stabilize this structure have recently been identified as potential anticancer drugs. Among the potential G-quadruplex binders, we have studied the binding ability of berberine and sanguinarine, two members of the alkaloid family, an important class of natural products long known for medicinal purpose. Our spectroscopic (CD, NMR, and fluorescence) studies and molecular modeling approaches revealed binding modes at ligand-complex stoichiometries >1:1 and ligand self-association induced by DNA for the interactions of the natural alkaloids berberine and sanguinarine with the human telomeric G-quadruplex DNA.
