Synthesis of bis-Isoxazole-bis-Ethylene Dinitrate and bis-Isoxazole-tetra-Ethylene Tetranitrate: Potential Energetic Plasticizers

The syntheses and characterizations of two new energetic compounds based on a bis-isoxazole scaffold are presented. The syntheses employ a metal-free [3+2] cycloaddition of an alkyne and a nitrile oxide. In addition, we report the molecular structure of these compounds as determined by single crystal x-ray diffractometry. Both materials have favourable sensitivity properties and low melting points. Their energetic properties indicate potential use as propellant plasticizers.

Sterically induced conformational restriction: Discovery and preclinical evaluation of novel pyrrolo[3,2-d]pyrimidines as microtubule targeting agents

The discovery, synthesis and biological evaluations of a series of nine N5-substituted-pyrrolo[3,2-d]pyrimidin-4-amines are reported. Novel compounds with microtubule depolymerizing activity were identified. Some of these compounds also circumvent clinically relevant drug resistance mechanisms (expression of P-glycoprotein and betaIII tubulin). Compounds 4, 5, and 8?13 were one to two-digit nanomolar (IC50) inhibitors of cancer cells in culture. Contrary to recent reports (Banerjee et al. J. Med. Chem. 2018, 61, 1704?1718), the conformation of the most active compounds determined by 1H NMR and molecular modeling are similar to that reported previously and in keeping with recently reported X-ray crystal structures. Compound 11, freely water soluble as the HCl salt, afforded statistically significant inhibition of tumor growth in three xenograft models [MDA-MB-435, MDA-MB-231 and NCI/ADR-RES] compared with controls. Compound 11 did not display indications of animal toxicity and is currently slated for further preclinical development.

Atom-economic generation of gold carbenes: Gold-catalyzed formal [3+2] cycloaddition between ynamides and isoxazoles

The generation of gold carbenes via the gold-catalyzed intermolecular reaction of nucleophiles containing relatively labile N-O or N-N bonds with alkynes has received considerable attention during recent years. However, this protocol is not atom-economic as the reaction produces a stoichiometric amount of pyridine or quinoline waste, the cleaved part of the N-O or N-N bonds. In this article, we disclose an unprecedented gold-catalyzed formal [3+2] cycloaddition between ynamides and isoxazoles, allowing rapid and practical access to a wide range of synthetically-useful 2-aminopyrroles. Most importantly, mechanistic studies and theoretical calculations revealed that this reaction presumably proceeds via an alpha-imino gold carbene pathway, thus providing a strategically novel, atom-economic route to the generation of gold carbenes. Other significant features of this approach include the use of readily-available starting materials, high flexibility, simple procedure, mild reaction conditions, and in particular, no need to exclude moisture or air (“open flask”).

Accelerated catalysis of olefinic epoxidations

Rhenium-catalyzed epoxidation of olefinic substrates is accelerated by the use of acclerants having a nitrogenous aromatic heterocyclic structure. Use of the accelerants also enables the use of aqueous hydrogen peroxide as an oxidant. To achieve optimum acceleration, the accelerant should have a concentration within a range from 2.0 mole percent to 100 mole percent of the acclerant with respect to 1 mole of the olefinic substrate. Use of the accelerant also results in an increased yield with respect to the conversion of the olefinic substrate to epoxide product.

High-Pressure Characterization of Melt-Castable Biisoxazole Energetics: 3,3?-Biisoxazole-5,5?-bis-(Methylene) Dinitrate and 3,3?-Biisoxazole-4,4?,5,5?-Tetrakis-(Methylene Nitrate)

The high-pressure behavior of 3,3?-biisoxazole-5,5?-bis-(methylene) dinitrate (BIDN) and 3,3?-biisoxazole-4,4?,5,5?-tetrakis-(methylene nitrate) (BITN) have been studied at room temperature to 25 GPa by Raman spectroscopy and powder X-ray diffraction. The Raman spectra, powder patterns, and calculated unit-cell volumes at select pressures show qualitative agreement with first-principles density function theory calculations. Over this pressure range, no evidence of polymorphism was observed. The lack of observed phase changes can be partially attributed to the strengthening of hydrogen bonding observed with pressure increase. These insights point to the potential importance of hydrogen bonding in potential melt-castable materials.

Probing the adsorption behavior of oxazole and isoxazole heterocyclic compounds onto B12N12 nanocluster surface in gas and aqueous mediums through DFT calculations

The adsorption of oxazole and isoxazole molecules over the pristine B12N12 nanocluster is investigated in terms of its geometric, the adsorption energies and the electronic properties using density functional theory calculations. The results indicate that the pristine cluster effectively chemisorbs with the oxazole and isoxazole molecules through their nitrogen atoms; whereas the interaction through the oxygen atoms is not considerable. The HOMO-LUMO gap of the cluster decrease by the adsorption of heterocycle rings. The role of solvent in improving the adsorption properties over the B12N12 surface is also considered. The obtained adsorption energies in aqueous medium are more negative than gas phase implied to the stability of the B12N12/ heterocycles complexes in the aqueous medium. Indeed, the interactions of some oxazole and isoxazole derivatives with this cluster are also investigated. The current study provides the knowledge about the performance of the B12N12 cluster in adsorbing oxazole and isoxazole moleculest.

Disulfide linked pyrazole derivatives inhibit phagocytosis of opsonized blood cells

Immune thrombocytopenia (ITP) is caused by production of an autoantibody to autologous platelets. ITP can be treated either by reducing platelet destruction or by increasing platelet production. Fcgamma receptor mediated phagocytosis of the opsonized blood cells is a well-accepted mechanism for the underlying pathogenesis of ITP and inhibition of this phagocytosis process with small molecules is a potential strategy for the development of drugs against ITP. A broad screen indicated that 4-methyl-1-phenyl-pyrazole derivative (1) could inhibit the phagocytosis of opsonized blood cells with weak potency. We reveal here the discovery of the polysulfide products, synthesis of various 1-phenyl-pyrazole derivatives, and the biological evaluation of pyrazole derivatives as inhibitors of phagocytosis for potential use as therapeutics for ITP. Substitution at C4 of the pyrazole moiety in the disulfide-bridged dimers influenced the potency in the increasing order of 10 ? 11 ? 16 < 19 < 20. A novel scaffold, 20 with an IC50 of 100 nM inhibiting opsonized blood cell phagocytosis was identified as a potential candidate for further studies. Confirmation of the disulfide bridge additionally provides clues for the non-thiol or non-disulfide bridge carrying ligands targeting ITP and other similar disorders. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 62348-13-4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 62348-13-4, in my other articles.
