Identifying cancer-related molecular targets of Nandina domestica Thunb. by network pharmacology-based analysis in combination with chemical profiling and molecular docking studies

Ethnopharmacological relevance: The fruits of Nandina domestica Thunb. have served as folk medicines in Chinese and Japanese tradition for treatment of several tumors including pharynx tumor and tooth abscess for many years, yet its exact mechanism of action is not yet known. Aim of the study: The study targets the identification of the main constituents of the fruits extracts and investigation of their mode of action in cancer therapy via pharmacology-based analysis and molecular docking. Materials and methods: The different extracts of N. domestica Thunb. were analyzed via UPLC?MS/MS for identification of their active constituents. STITCH, DAVID, KEGG and STRING database were utilized for construction of compound-target and compound-target-pathway networks using Cytoscape 3.2.1. Molecular docking analysis of the top hit compounds was performed against the identified top hit molecular targets in the constructed networks. In vitro-testing of Nandina domestica Thunb. against colorectal cancer cell lines was carried out and correlated to the chemical profile of the extract to identify important biomarkers. The ADME properties of the active compounds were also evaluated. Results: 22 compounds were identified by UPLC?MS/MS analysis and were forwarded to network pharmacology-based analysis. Results showed the enrichment of 5 compounds and 4 molecular targets in the network namely; AKT1, CASP3, MAPK1 and TP53. The pathway analysis of the identified targets revealed that 15 cancer-related pathways were enriched including colorectal cancer, endometrial cancer and small-cell lung cancer. In-vitro testing of the extracts against colo-rectal cancer cell lines revealed the fractions enriched in the identified hit compounds were indeed the most active as revealed from the HCA-heat-map. ADME results showed that all compounds were drug-like candidates showing acceptable values according to Lipinski’s rule. Conclusions: Network pharmacology analysis revealed that the compounds isoquercitrin, quercitrin, berberine, chlorogenic acid and caffeic acid showed strong synergistic interactions with the cancer-related targets and pathways. It could be concluded that N. domestica Thunb. constituents affect both apoptosis and Akt-signaling pathways during the stages of early and intermediate adenoma through interaction with the targets CASP3 and MAPK1 (ErC2) while during the stages of late adenoma and carcinoma, the compounds acts through the p53 and ErbB signaling pathways.

Transfer of stereochemical information in a minimal self-replicating system

The rational design, synthesis, and characterization of a minimal self-replicating system based on a 1,3-dipolar cycloaddition between a nitrone and a maleimide is presented. The importance of molecular recognition in this system is demonstrated using a competitive inhibitor. Doping experiments demonstrate that only one of the two diastereoisomeric products of the cycloaddition reaction is capable of acting as an efficient template for its own formation, accelerating the reaction between the nitrone and maleimide and controlling the stereochemical outcome of the reaction.

A scalable process for the synthesis of the Bcl inhibitor obatoclax

Recently we created the novel indolylprodigiosin derivative 2 (obatodax) and demonstrated its ability to antagonize multiple members of the B-cell lymphoma (Bd) family of antiapoptotic proteins. The compound has shown potent anticancer activity in several animal tumor models. Obatodax is now in Phase 1b and 2 clinical trials directed against multiple hematologic and solid tumor malignancies. To support its clinical development, a new scalable synthesis was required. Obatodax has been prepared using a three-step synthesis, starting from commercially available 4-methoxy-3-pyrrolin-2-one. The reaction sequence involves a haloformylation reaction followed by a Suzuki cross-coupling reaction with an indole-2-boronic add. The synthesis is completed by an acid-mediated condensation with 2,4-dimethyl-1H-pyrrole.

PMR SPECTRA AND cis-trans ISOMERISM OF 2-METHYLENEPYRROLIDINE AND 2-METHYLENETETRAHYDROFURAN DERIVATIVES

A number of secondary enamines and cyclic enol ethers (2-methylenetetrahydrofuran derivatives) were synthesized by the reaction of O-methylbutyrolactim and 2,2-diethoxytetrahydrofuran, respectively, with compounds that have an active methylene link.The absence of reversible cis-trans isomerization was established in a study of the PMR spectra of these compounds.The configuration of the secondary enamines is determined by the possibility of the formation of a strong intramolecular hydrogen bond between the carbonyl-containing substituent and the NH group.In the case of the cyclic enol ethers it was shown that the energy barrier to cis-trans isomerization is greater than 25 kcal/mole and that, as a consequence of this, the geometrical isomers can be separated preparatively.

Ruthenium catalyzed decarbonylative arylation at sp3 carbon centers in pyrrolidine and piperidine heterocycles

This paper describes the development of a new catalytic transformation, the ruthenium-catalyzed decarbonylative arylation of cyclic 2-amino esters, which replaces the ester group with an aryl ring at the sp3 carbon center. For example, proline ester amidine 1 is converted to 2-arylpyrrolidine 3 in the presence of arylboronic acids or esters as arene donors and Ru 3(CO)12 as the catalyst. This process provides a rapid access to a variety of 2-arylpyrrolidines and piperidines from commercially available proline, hydroxyproline, and pipecolinate esters. The examination of the substrate scope also showed that many arene boronic acids and boronate esters serve as coupling partners. The high chemoselectivity of this process was demonstrated and ascribed to the significant rate difference between the decarbonylative arylation and the C-H arylation. The decarbonylative arylation complements the C-H arylation, since the latter process lacks control over the extent of functionalization, affording a mixture of mono- and bis-arylpyrrolidines. When applied in tandem, these two processes provide 2,5-diarylpyrrolidines in two steps from the corresponding proline esters. It was also demonstrated that the required amidine or iminocarbamate directing group fulfills two major functions: first, it is essential for the ester activation step, which occurs via the coordination-assisted metal insertion into the acyl C-O bond; second, it facilitates the decarbonylation, via the stabilization of a metallacycle intermediate, assuring the formation of the 2-arylated products instead of the corresponding ketones observed before by others.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 5264-35-7, and how the biochemistry of the body works.Synthetic Route of 5264-35-7

The Pd-catalyzed C-H alkylation of ortho -methyl-substituted aromatic amides with maleimide occurs preferentially at the ortho -methyl C-H bond over the ortho -C-H bond

The reaction of ortho-methyl-substituted aromatic amides with maleimides in the presence of Pd(OAc)2 and AgOAc results in C-H alkylation at the ortho-methyl C-H bond. DFT calculations indicate that the formation of a five-membered palladacycle is a kinetically favorable step, but the insertion of the maleimide into the six-membered palladacycle is energetically favored.

Solvent dependent energy transfer of N-bridged naphthalimide- bisindolymaleimide fluorescent dyes

Double build-in chromophores, naphthalimide (NIM) and bisindolymaleimide (BIM), were synthesized and characterized. Absorption and emission properties of double chromophores dye were fully investigated in various solvents. The priority of through bond energy transfer (TBET) to NTM or BIM is solvent dependent. There appears large different emission wavelength change in CHCl 3 and DMF with alkyl attached to BIM. However, the product of cyclohexyl substitution leads to a different emission behavior, which is non-sensitivity to solvent polarity. Quantum chemical calculation for the molecular orbital reveals that intramolecular charge transfer (ICT) is the key factor for their different opto-electronic properties.
