Study on antitumor molecular mechanism of Chelidonium majus based on network pharmacology

Objective Chelidonium majus is applied to tumor therapy with good clinical effect and weak adverse effect. To explain the molecular mechanism of antitumor effect scientifically, the network pharmacology method was used to screen effective parts and major active components of C. majus and to construct the active compounds-targets network. Methods ADME calculation method was used to filtrate the active components of C. majus, and then the targets of the main active ingredients were collected by literature mining and multiple databases, and the targets of the compound were screened using the SysDT model. Besides, the compounds-targets network was constructed by Cytoscape software and network topology analysis was carried out. Biological information annotation databases (DAVID) was used to analyze the molecular function and biological pathway of the action targets. Results Alkaloids were the major active components of C. majus, 21 alkaloid components were screened out by ADME calculation method with 168 related targets, and 60 closely cancer-related pathways. Those pathways were integrated, with which a comprehensive C. majus antitumor pathway was constructed. According to the results of network topology analysis and ingredient correction results, it was speculated that chelerythrine, berberine and sanguinarine were the main active ingredients in C. majus, acting on the targets of PTGS2, SCN5A, F10, NCOA2, CHRM3, AR, TP5, CASP1/3/9, DRD1, MAPT, MAPK1, BLM, etc. Conclusion The antitumor activities of C. majus were mainly by inducing cell apoptosis and inhibiting cell proliferation, metastasis and invasion as phenotype intervention mode in network, thereby to exert antitumor activities and a certain central analgesic effect.

Conjugation between maleimide-containing Pt(IV) prodrugs and furan or furan-containing drug delivery vectors via Diels-Alder cycloaddition

Pt(IV) complexes are considered to act as antitumor prodrugs and their in vivo activity can be improved exploiting drug targeting and delivery strategies. With a view to such applications, the maleimide-containing ligand 2-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid was used to produce the cisplatin-based Pt(IV) complexes (OC-6-44)-diamminedichlorido(ethanolato)(2-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetato)platinum(IV) and (OC-6-44)-acetatodiamminedichlorido(2-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetato)platinum(IV). These complexes underwent Diels-Alder reaction with furan, used as a model molecule to set up the experimental conditions, at ambient temperature up to 50 h, with limited decomposition. Finally, the reaction between the maleimide-containing Pt(IV) complexes and silica nanoparticles decorated with furan were successfully used as a proof-of-concept to demonstrate the clickability of functionalized vectors for drug delivery.

Synthesis, characterization and cytotoxicity appraisal of original 1, 2, 3-Triazole derivatives, against breast cancer cell lines (MDA-MB-231)

The present study established the efficient separate synthesis of four unique 1, 2, 3-triazole derivatives (M1, M2, M3, M4) via conducting 1,3-dipolar cycloaddition of N-((4-azidophenyl) sulfonyl) acetamide, with substituted N-phenylmaleimide. FTIR, 1H NMR, 13C NMR, and mass spectra were utilized for the characterization of the triazoles. The cytotoxic activities of these compounds, with regards to breast cancer cell lines (MDA-MB-231), were then evaluated. The cytotoxicity pre-screening outcomes for 100 muM portrayed a variety of actions, while the IC50 values with concentrations of 0-500 MuM for 48 hours, the results are 2.542, 2.929, 2.429, and 2.864 MuM for the compounds M1, M2, M3, and M4 respectively. Remarkably, the M2 and M4 para-substituted compounds exhibited superior IC50 values, in comparison to the M1 and M3 ortho-substituted compounds. This suggests that the M1 and M3 compounds have the potential to perform as against breast cancer.

Protopine protects mice against LPS-Induced acute kidney injury by inhibiting apoptosis and inflammation via the TLR4 signaling pathway

Corydalis humosa Migo is a traditional Chinese medicine that clears away damp heat, relieves sore. Protopine (PRO) is an alkaloid component isolated from C. humosa Migo. However, the role of protopine in acute kidney injury (AKI) has not yet been reported. This study aims to investigate the effect and mechanism of protopine isolated from C. humosa Migo on lipopolysaccharide (LPS)-induced AKI in mice. Inflammation accumulation was assessed by small animal living imaging. The blood urea nitrogen (BUN), and serum creatinine (Scr) were measured to assess the effects of protopine on renal function in LPS-induced AKI. The levels of tumor necrosis factor (TNF), interleukin-2 (IL-2), interferon- (IFN-), and (interleukin-10) IL-10 in serum were detected by cytometric bead array. Flow cytometry was used to detect the levels of reactive oxygen species (ROS) in primary kidney cells. The proportions of granulocytes, neutrophils, and macrophages in peripheral blood were examined to evaluate the effect of protopine on immune cells in mice with AKI. Toll-like receptor (TLR4) and apoptotic signaling pathway were detected byWestern blot analysis. The results showed that protopine markedly improved the renal function, relieve inflammation, reversed inflammatory cytokines, transformed apoptosis markers, and regulated the TLR4 signaling pathway in mice with AKI induced by LPS. The protopine isolated from C. humosa Migo protected mice against LPS-induced AKI by inhibiting apoptosis and inflammation via the TLR4 signaling pathway, thus providing a molecular basis for a novel medical treatment of AKI.

Tautomerism of the Monohydroxy Derivatives of Five-Membered O, N, and S Heterocycles

The O-deuterated enolic tautomers 3-deuteroxybenzofuran, 3-deuteroxybenzothiophene, 3-deuteroxyindole, 3-deuteroxy-1-methylindole, 3-deuteroxyfuran, 3-deuteroxythiophene, 2-deuteroxybenzothiophene, and 2-deuteroxythiophene have been generated in solution in mixtures of CD3COCD3, CD3CN, or CD3SOCD3 with D2O by hydrolysis of their trimethylsilyl derivatives in the presence of DCl (1E-3 – 1E-4 M) and characterized by 1H NMR spectroscopy.Solutions of 3-hydroxypyrrole and of 3-hydroxy-1-methylpyrrole were obtained by methanolysis of their trimethylsilyl derivatives,evaporation of the methanol, and immediate dissolution in DMSO-d6.The carbocyclic analogues of the bicyclic heterocyclic enols 3-deuteroxyindene and 2-deuteroxyindene were also generated in solution.Attempts to prepare solutions of 2-deuteroxyfuran, 2-deuteroxypyrrole, and 2-deuteroxy-1-methylpyrrole were unsuccessful.The kinetics of ketonization of the OH forms of these enols have been investigated in water or aqueous acetonitrile solution.The equilibrium constants for the keto-enol tautomerism were also determined either by direct measurement when sufficient enol was present at equilibrium or as the ratio of the rate constant for enolization of the keto form to that for ketonization of the enol form, the former being determined by the iodine-trapping technique.The effect of solvent on the equilibrium constants was also studied.Sufficient data were available for the equilibrium between 3-hydroxyindole and 3-ketoindole for them to be analyzed by the four-parameter equation of Mills and Beak to yield an a value of 2.4 and a b value of -3.0.The pKas of the bicyclic enols were measured. 3-Hydroxybenzofuran and3-hydroxybenzothiophene are stronger acids than 3-hydroxyindole and 3-hydroxy-1-methylindole.The ketonization reactions are general acid and general base catalyzed and their mechanisms are discussed.

Development of a novel affinity labeling method for target identification of bioactive small molecules

Target identification (target-ID) is an important step in elucidating the mechanisms of action of bioactive small molecules. In the past few decades, a number of target-ID methods have been developed. Among these, affinity labeling has been reliably used for specific modifications, as well as for the identification of weakly interacting protein targets, membrane-associated protein targets, and target-interacting proteins under native cellular conditions, which are generally difficult to achieve by conventional pull-down methods. In general, affinity labeling utilizes chemical probes composed of a bioactive small molecule, a reactive group, and a detection unit. However, the design and synthesis of highly functionalized chemical probes is often time-consuming. To address this issue, we have recently developed some simple affinity labeling methods using small fluorogenic tags, such as 4-alkoxy-7-nitro-2,1,3-benzoxadiazole (O-NBD), 2,3-dichloromaleimide (diCMI), and 4-azidophthalimide (AzPI), and successfully achieved the specific fluorescent labeling of target proteins, even in living cells. These methods should be useful for target-ID in phenotypic drug discovery.
