Bulk Inclusions of Double Pyridazine Molecular Rotors in Hexagonal Tris(o-phenylene)cyclotriphosphazene

A new generation of double pyridazine molecular rotors differing in intramolecular dipole-dipole spacing was synthesized. All rotor molecules formed bulk inclusions in a tris(o-phenylenedioxy)cyclotriphosphazene (TPP) host. Results of dielectric spectroscopy were fitted to a pair of nine-state models that accounted for interactions of neighboring dipoles at either an aligned or opposed possible orientation of the local threefold dipole rotation potentials within a channel of the TPP host. The results indicate dipole- dipole interaction strengths at the 100 to 200 K scale that lead dipoles to preferentially populate a subset of low-energy configurations. They also reveal that pyridazines with ethynyl substituents in 3- and 6-positions have slightly higher rotational barriers (3.2-3.5 kcal/mol) than those carrying one ethynyl and one tert-butyl group (1.9-3.0 kcal/mol). Upon cooling, these barriers reduce the rate of thermal transitions between the potential wells so much that the inclusions cannot achieve ordered dipolar ground states.

Development of pyridazine derivatives as potential EGFR inhibitors and apoptosis inducers: Design, synthesis, anticancer evaluation, and molecular modeling studies

Novel hybrids of pyridazine-pyrazoline were synthesized aiming to develop new antiproliferative candidates. All compounds were submitted to the National Cancer Institute (NCI), USA, and many were proved to have significant antiproliferative activity. In addition, in vitro studies of the epidermal growth factor receptor (EGFR) inhibition showed that compounds IXn, IXg, IXb and IXI exhibited excellent inhibitory effect (IC50 = 0.65, 0.75, 0.82 and 0.84 mu M, respectively) compared to Erlotinib (IC50 = 0.95 mu M). The mechanistic effectiveness in cell cycle progression, apoptotic induction and gene regulation were assessed for the promising compounds IXg and IXn due to their significant EGFR inhibition. Flow cytometeric analysis indicated that compounds IXg and IXn result in increased cell numbers in phase G2/M, suggesting cell cycle arrest in phase G2/M in UO-31cells. Furthermore, real time PCR assay illustrated that compounds IXg and IXn elevated Bax/Bcl2 ratio which confirmed the mechanistic pathway of them. Moreover, the apoptotic induction of UO-31 renal cancer cells was enhanced effectively through activation of caspase-3 by compounds IXg and IXn. On the other hand, molecular docking study was performed to investigate binding mode of interaction of compounds with EGFR-PK in the active site with the aim of rationalizing its promising inhibitory activity. Finally, based on the aforementioned findings, compounds IXg and IXn could be considered as effective apoptosis modulators and promising leads for future development of new anti-renal cancer agents.

Pyridazine as a privileged structure: An updated review on anticancer activity of pyridazine containing bioactive molecules

Identification of potent anticancer agents with high selectivity and low toxicity remains on the way to human health. Pyridazine featuring advantageous physicochemical properties and antitumor potential usually is regarded as a central core in numerous anticancer derivatives. There are several approved pyridazine-based drugs in the market and analogues currently going through different clinical phases or registration statuses, suggesting pyridazine as a promising drug-like scaffold. The current review is intended to provide a comprehensive and updated overview of pyridazine derivatives as potential anticancer agents. In particular, we focused on their structure-activity relationship (SAR) studies, design strategies, binding modes and biological activities in the hope of offering novel insights for further rational design of more active and less toxic anticancer drugs.

Tunable Optical and Photocatalytic Properties of Low-Dimensional Copper(I)-Iodide Hybrids Using Coordinating Organic Ligands

A family of copper(I)-iodide/organic hybrid compounds was investigated for the impact of coordinating organic ligands on their structures, as well as on their optical and photocatalytic properties. This included the synthesis of two new crystalline compounds, [(CuI)(2) (bpmd)] and [(CuI)(2) (bpp)] (bpmd = 2,2′-bipyrimidine, bpp = 2,3-bis(2-pyridyl)pyrazine), both of which consist of chain structures formed by (CuI)(2) rhombus-shaped dimers that are further coordinated to the Ngroups of the bridging organic ligands. To more broadly investigate structure-property relationships within this system, nine related copper(I)-iodide/organic hybrid compounds, that is, [(CuI)(2)L-n] (n = 1 or 2; L = 1,2-bis(4-pyridyl) ethylene (bpe); 2,2’bipyrimidine (bpmd); 2,3-bis(2-pyridyl) pyrazine (bpp); 4,4′-bipyridine (44bpy); pyridazine (pdz); pyrimidine (pmd); pyrazine (pz); pyrazinamide (pza); quinoxaline (quin)) were also prepared in high purity containing extended (CuI)(infinity) chains or sheets coordinated to bridging or terminating organic ligands. The optical absorption edges of all hybrid compounds were measured using UV-vis diffuse reflectance spectroscopy. Incorporation of the organic ligand functions to significantly decrease the bandgap size with respect to the parent gamma-CuI (E-g = 3.1 eV = optical band gap) into the visible-light wavelengths spanning from similar to 1.7 to , similar to 2.6 eV for the [(CuI)(2)L-n] family. Their optical bandgap sizes were found to be controlled specifically by the framework density, the number of N atoms bonded to each Cu atom, and the number of N atoms in each heterocyclic ring within the ligands. Their photocatalytic properties were investigated and found to show high activity for the light-driven degradation of methylene blue, for example, degrading as fast as within similar to 20 min for [(CuI)(pza)]. These photocatalytic activities were found to be related to the orbital energies of the Cu 3d(10) and I 5p(6) relative to that of the organic ligands, as well as to the local and extended connectivity of their crystalline structures. In contrast to the instability of other metal halide compounds, for example, lead-based halide perovskites, all copper(I)-iodide hybrids were found to be stable within aqueous solutions while under irradiation by ultraviolet and visible light. These results demonstrate the stability and photocatalytic activity copper(I)-iodide/organic hybrids in light-driven redox reactions.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 401-78-5, you can contact me at any time and look forward to more communication. Safety of 3-Bromobenzotrifluoride.

Antioxidative activity analyses of some pyridazine derivatives using computational methods

Pyridazine-derivative compounds have attracted considerable attention in different fields for many years due to their various biological activities such as antimicrobial and antitumoral. Simultaneously, antioxidative activity is one of the most important properties of them. With this perspective, antioxidative properties of eight different pyridazine derivatives have been investigated in accordance with three main mechanisms (HAT, SET, and SPLET). The investigation has been carried out with HF/6-31+G(d,p), B3LYP/6-31G(d,p), B3LYP/6-31+G(d,p), and MP2/6-31+G(d,p) level of theories in both gas and liquid phases. Furthermore, several molecular descriptors, bond and proton dissociation enthalpies, ionization potentials, proton affinities, and electron transfer enthalpies of investigated molecules have been calculated and antioxidative properties of the molecules have been sorted in accordance with the calculated values. Besides, effects of methods, basis sets, and solvent have been discussed. This computational study has determined the antioxidative capacity of 1A2D as the highest in each studied method and phases.

DFT study of structural and electronic properties of 1,4-diarylcyclopenta[d] pyridazines and oxazines for non-linear optical applications

Polymer and molecular-based electronic materials incorporating heterocycles like thiophenes and pyrroles are attractive possibilities as substitutes for semimetal materials. Heterocyclic materials are heavily studied in this regard due to the large variations in possible substrates. Herein we evaluated four different 5,6-fused ring heterocycles to gain a better understanding of any favorable optical and electronic properties that were due to incorporation of certain moieties. The molecules chosen would highlight the effects that the central ring (pyridazine versus oxazine), aromatic substituent, and heterocyclic side group may have on electronic and optical properties. Computational analysis of these four molecules was done using density functional theory (B3LYP and PBEPBE) with 6-31G(d,p), 6-311 ++G(d,p), and cc-pVTZ basis sets. The constituent molecules were optimized, and calculations were done for the dipole moment, polarizability, first-order hyperpolarizability (beta), HOMO and LUMO orbitals, and a natural bonding order (NBO) analysis. These calculations allow for the study of charge density via electrostatic potential mapping and bonding orbitals. The results indicated that the pyridazine molecules presented here are more favorable than the oxazines for non-linear optical (NLO) applications. It is also noted that side ring substituents (thienyl and furyl) in the two pyridazines studied showed very little calculated differences. Finally, heterocyclic rings showed more favorable properties when incorporated as substituents for NLO applications over hydrocarbon aromatics.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 19430-93-4. The above is the message from the blog manager. Computed Properties of C6H3F9.

Pyrazole[3,4-d]pyridazine derivatives: Molecular docking and explore of acetylcholinesterase and carbonic anhydrase enzymes inhibitors as anticholinergics potentials

Recently, the pyridazine nucleus has been widely studied in the field of particular and new medicinal factors as drugs acting on the cardiovascular system. Additionally, a number of thienopyridazines have been claimed to possess interacting biological macromolecules and pharmacological activities such as NAD(P)H oxidase inhibitor, anticancer, and identified as a novel allosteric modulator of the adenosine A1 receptor. The literature survey demonstrates that coumarin, 1,2-pyrazole benzothiazole, and 1,3- thiazole scaffolds are the most versatile class of molecules. In this study, a series of substituted pyrazole[3,4-d]pyridazine derivatives (2a-n) were prepared, and their structures were characterized by Mass analysis, NMR, and FT-IR. These obtained pyrazole [3,4-d]pyridazine compounds were very good inhibitors of the carbonic anhydrase (hCA I and II) isoenzymes and acetylcholinesterase (AChE) with K-i values in the range of 9.03 +/- 3.81-55.42 +/- 14.77 nM for hCA I, 18.04 +/- 4.55-66.24 +/- 19.21 nM for hCA II, and 394.77 +/- 68.13-952.93 +/- 182.72 nM for AChE, respectively. The possible inhibition mechanism of the best-posed pyrazole[3,4-d]pyridazine and pyrazole-3-carboxylic acid derivatives and their interaction with catalytic active pocket residues were determined based on the calculations.
