Pyrrolidinohydroquinazolines – A novel class of CCR3 modulators

A novel class of CCR3 modulators is described. Starting with lead compound 4a (Ki: 110 nM), which turned out to be an antagonist of eotaxin at the CCR3 receptor, further optimization led to compound 8b (Ki: 28 nM), which surprisingly proved to be an agonist.

N,N’-DIMALEIMIDES IN THE DIELS-ALDER REACTION. I. KINETICS OF THE UNCATALYZED REACTION WITH trans,trans-1,4-DIPHENYLBUTADIENE AND 1,3-DIPHENYLISOBENZOFURAN

The kinetic behavior of a series of diimides, in which the maleimide rings are linked through various bridges, in the Diels-Alder reaction with trans,trans-1,4-diphenylbutadiene and 1,3-diphenylisobenzofuran was studied.The energies of charge transfer were determined and the electron affinities were calculated by spectrophotometry of the charge-transfer complexes between the imides and hexamethylbenzene.Although the rates of reaction of the bisimides with the investigated dienes differ by seven orders of magnitude, the general type of “diene-donor, dienophile-acceptor” reaction is preserved.

Probing selectivity in recognition-mediated dynamic covalent processes

Two simple recognition-mediated dynamic Diels-Alder systems are used to probe the role of kinetics and thermodynamics in determining the equilibrium position in exchanging libraries and the time taken to reach that equilibrium. The selectivity expressed by recognition-driven dynamic processes is demonstrated to be less than the free-energy difference between the components as a result of compensatory effects arising from the extent of conversion to products within the library.

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.

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.

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.
