Protopine Production by Fumaria Cell Suspension Cultures: Effect of Light

Protopine biosynthesis in Fumaria rostellata and Fumaria officinalis cell suspensions was investigated. For the first time, we reported for calli and cell suspensions obtained from F. rostellata and F. officinalis. Callus induction was initiated on a Murashige and Skoog medium, supplemented with sucrose and various concentrations of plant growth regulators: 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzylaminopurine (BAP). The best morphological characteristics, growth behavior, and protopine biosynthesis were observed for two callus lines (5FRL14 and 12FOL1) cultivated under submerged conditions, at low concentration of 2,4-D (0.2 and 0.5 mg/L) and higher concentration of BAP (2.0 and 3.0 mg/L). The maximal yield of protopine was accumulated from cell suspension of F. rostellata (line 5FRL14) cultivated under illumination49.6 mg/L. Time courses of utilization of sucrose, ammonium, nitrate, and phosphate ions in cultural liquid and acetylcholinesterase inhibitory activity of alkaloid extracts of studied suspensions are also presented.

Hydroxylations microbiologiques de pyrrolidinones-2 (note de laboratoire)

Microbial hydroxylations of various pyrrolidin-2 ones, especially N-acylated, with Beauveria sulfurescens have been carried out.The regioselectivity depends on the nature of the substituent on the nitrogen atom and the hydroxylation may occur at position 3,4 or 5 of the heterocycle.Hydroxylations at position 3 or 4 occur with low enantioselectivity.

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.
