Abstract
Cancer is the second leading cause of death in the world and its incidence is expected to increase with the aging of the world's population and globalization of risk factors. Natural products and their derivatives have provided a significant number of approved anticancer drugs and the development of robust and selective screening assays for the identification of lead anticancer natural products are essential in the challenge of developing personalized targeted therapies tailored to the genetic and molecular characteristics of tumors. To this end, a ligand fishing assay is a remarkable tool to rapidly and rigorously screen complex matrices, such as plant extracts, for the isolation and identification of specific ligands that bind to relevant pharmacological targets. In this paper, we review the application of ligand fishing with cancer-related targets to screen natural product extracts for the isolation and identification of selective ligands. We provide critical analysis of the system configurations, targets, and key phytochemical classes related to the field of anticancer research. Based on the data collected, ligand fishing emerges as a robust and powerful screening system for the rapid discovery of new anticancer drugs from natural resources. It is currently an underexplored strategy according to its considerable potential.

Abstract
G-quadruplex (G4) oligonucleotides are higher-order DNA and RNA secondary structures of enormous relevance due to their implication in several biological processes and pathological states in different organisms. Strategies aiming at modulating human G4 structures and their interrelated functions are first-line approaches in modern research aiming at finding new potential anticancer treatments or G4-based aptamers for various biomedical and biotechnological applications. Plants offer a cornucopia of phytocompounds that, in many cases, are effective in binding and modulating the thermal stability of G4s and, on the other hand, contain almost unexplored G4 motifs in their genome that could inspire new biotechnological strategies. Herein, we describe some G4 structures found in plants, summarizing the existing knowledge of their functions and biological role. Moreover, we review some of the most promising G4 ligands isolated from vegetal sources and report on the known relationships between such phytochemicals and G4-mediated biological processes that make them potential leads in the pharmaceutical sector.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 284:114785. [PMID: 34718104 DOI: 10.1016/j.jep.2021.114785] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Revised: 10/23/2021] [Accepted: 10/25/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saussurea obvallata (DC.) Edgew. is a traditional Tibetan medicine used for the treatment of inflammation-related diseases, but the scientific validation was very limited. AIM OF THE STUDY This study aimed to rapid screen and targeted isolate cyclooxygenase-2 (COX-2) inhibitors from S. obvallata extract. MATERIALS AND METHODS An efficient ligand-fishing method based on affinity solid phase extraction (A-SPE) combining with HPLC was developed. The identified COX-2 inhibitors were separated using preparative liquid chromatography. In vitro COX-2 inhibition assays were employed to confirm the inhibitory activities of the isolated compounds. In addition, the effect of the isolated compounds on the production of prostaglandin E2 (PGE2) and the expression of COX-2 in LPS-induced RAW 264.7 were evaluated. RESULTS A total of four phenylpropanoids, isolariciresinol, syringaresinol, pinoresinol and balanophonin were targeted isolated as COX-2 inhibitors with IC50 values of 36.4 ± 2.6 μM, 23.1 ± 1.8 μM, 3.6 ± 0.3 μM and 12.1 ± 0.9 μM, respectively. The isolated compounds significantly inhibited LPS-induced NO production in a dose-dependent manner. And, the results of the inhibitory effect on the release of PGE2 and the expression of COX-2 in LPS-induced macrophages were consistent with A-SPE analysis. CONCLUSION The present work demonstrated that the developed A-SPE-HPLC method could successfully targeted isolated COX-2 inhibitors from S. obvallata extract. And, the isolation results indicated that the therapeutic effect of S. obvallata on inflammation-related diseases was partly based on the COX-2 active ingredients.

Abstract
It is urgent to obtain targeted drugs that selectively bind to pathological targets rather than physiological targets in the early stage of drug screening. G-Quadruplex has become one of the important targets in the development of anti-tumor drugs. However, drugs that target quadruplexes may also bind to dsDNA, which may lead to adverse reactions. In this study, a new three-phase laminar flow chip was constructed to enable the multi-components of a traditional Chinese medicine extract to dynamically and competitively bind with G-quadruplex DNA (on target) and double-stranded DNA (off target), so as to select high-efficiency and low-toxicity anti-tumor drugs. The results showed that there were five compounds in the extracts of Macleaya cordata seeds that exhibited obvious differences in binding to the two targets. Furthermore, the binding constants and modes of four identified alkaloids as they bound to two DNA targets were verified by fluorescence spectra and molecular docking methods. The toxicity to HepG2 and LO2 cells from the four alkaloids was also compared. The results showed that sanguinarine and chelerythrine could be used as candidate drugs with stronger binding to HT24 than DNA26. The chip can also be used for other types of double-target screening of other traditional Chinese medicine extracts or compound libraries.

Abstract
BACKGROUND G-quadruplexes have become important drug-design targets for the treatment of various human disorders such as cancer, diabetes and cardiovascular diseases. Recently, G-quadruplex structures have been visualized in the DNA of human cells and appeared to be dynamically sensitive to the cell cycle and stabilized by small molecule ligands. A small library of isoxazolo naphthoquinones (1a-h), which exhibited a strong antiproliferative activity on different cancer cell lines, was studied as potential ligands of G-quadruplex DNA. METHODS The DNA binding properties of a series of the selected compounds have been analyzed by fluorescence assays. NMR/modeling studies were performed to describe the complexes between G-quadruplex DNA sequences and two selected compounds 1a and 1b. RESULTS 1a and 1b in the presence of G-quadruplexes, d(T(2)AG(3)T)(4), d(TAG(3)T(2)A)(4) and d(T(2)G(3)T(2))(4), showed good ability of intercalation and the formation of complexes with 2:1 stoichiometry. 1a showed an important interaction with the sequence Pu22 belonging to the promoter of oncogenes c-myc. CONCLUSIONS The ligands directly interact with the external G-tetrads of the G-quadruplexes, without alterations in the structure of the G-quadruplex core. The role of the adenine moieties over the G-tetrads in the stabilization of the complexes was discussed. GENERAL SIGNIFICANCE The results obtained suggested that the strong antiproliferative activity of isoxazolo naphthoquinones is not due to the Hsp90 inhibition, but mainly to the interaction at the level of telomeres and/or at the level of gene promoter. These findings can be used as a basis for the rational drug design of new anticancer agents.

Abstract
Eucommia ulmoides bark has long been known as tonic herb, however, the systematic biochemical fingerprint analysis and corresponding structural identification are inadequate so far. Here we describe on-line surface plasmon resonance-high performance liquid chromatography-tandem mass spectrometry (SPR-HPLC-MS/MS) to fish out and identify human serum albumin (HSA) binders from E. ulmoides bark. A total of 22 HSA binders, including 4 iridoids, 11 lignans, 3 flavonoids and 4 phenolic acids, were identified or tentatively characterized based on their retention times, UV spectra and MS/MS spectrum with references or literature data, among which, geniposidic acid, geniposide and chlorogenic acid were the predominant HSA binders. In addition, the major characteristic fragmentation pathways of iridoids and lignans were investigated. The higher reusability and stability of the immobilized HSA allow the method cost-effective and high-throughput. Compared with conventional HPLC-MS/MS for chemical fingerprint analysis, SPR-HPLC-MS/MS is simple and easy to provide biochemical fingerprint, moreover, it is easy to identify low-content HSA binders because of the sample clean-up/concentration procedure.
