Synthesis and antiproliferative assessments of new derivatives of isothiazolo[3,4-d]pyrimidine

Various derivatives of 5-aryl-4-imino-3-(phenylamino)-4,5-dihydroisothiazolo[3,4-d]pyrimidines (3a-f) were synthesized. The synthesis has been done through treatment of 3-amino-4-cyano-5-(phenylamino)isothiazole with various aryl isothiocyanates. The isothiazole skeleton was obtained by the reaction of malononitrile and phenyl isothiocyanate followed by chloramine treatment. Some of the synthesized dihydroisothiazolo[3,4-d]pyrimidines were tested against different cancer cell lines, including ACHN, HeLa, HL-60, MCF-7, and PC3. Malignant cells were cultured in RPMI medium and incubated with different concentrations of the mentioned compounds. Cell viability was assessed using the MTS assay. The cytotoxicities of the synthesized compounds are not significant and are probably safe for other biological use.

Synthesis and pharmacology of glutamate receptor ligands: new isothiazole analogues of ibotenic acid

The naturally occurring heterocyclic amino acid ibotenic acid (Ibo) and the synthetic analogue thioibotenic acid (Thio-Ibo) possess interesting but dissimilar pharmacological activity at ionotropic and metabotropic glutamate receptors (iGluRs and mGluRs). Therefore, a series of Thio-Ibo analogues was synthesized. The synthesis included introduction of substituents by Suzuki and Grignard reactions on 4-halogenated 3-benzyloxyisothiazolols, reduction of the obtained alcohols, followed by introduction of the amino acid moiety by use of 2-(N-tert-butoxycarbonylimino) malonic acid diethyl ester. The obtained Thio-Ibo analogues ( 1, 2a- g) were characterized in functional assays on recombinant mGluRs and in receptor binding assays on native iGluRs. At mGluRs, the activity at Group II was retained for compounds with small substituents (2a – 2d), whereas the Group I and Group III receptor activities for all new compounds were lost. Detection of NMDA receptor affinity prompted further characterization, and two-electrode voltage-clamp recordings at recombinant NMDA receptor subtypes NR1/NR2A-D expressed in Xenopus oocytes were carried out for compounds with small substituents ( chloro, bromo, methyl or ethyl, compounds 2a – d). This series of Thio-Ibo analogues defines a structural threshold for NMDA receptor activation and reveals that the individual subtypes have different steric requirements for receptor activation. The compounds 2a and 2c are the first examples of agonists discriminating individual NMDA subtypes.

Volatile constituents from in vitro and ex vitro plants of Petiveria alliacea L.

In this work, the volatile compounds extracted by simultaneous distillation and extraction as well as the volatile constituents by solid phase micro-extraction (SPME) from different structures (in vitro and ex vitro roots, leaves, and inflorescence) of Petiveria alliacea were analyzed by GC/FID and GC/MS. Forty-one different compounds were identified. Differences were observed between plant structures and origin (either in or ex vitro). However, sulfur compounds were common to all samples, like bis(phenyl-methyl)-disulfyde, isothiazole (1,2-thiazole), 2-thiopropane, dimethyl sulphyde, ethylene disulfyde, and 2,3-dimethyl-thiirane. In vitro plant roots exhibited higher chemical diversity among the analyzed plant structures. Substances found in all analyzed structures of P. alliacea by SPME were benzaldehyde, calamenene and the hydrocarbons dodecane, tridecane, and tetradecane.

New routes to benzothiophenes, isothiazoles and 1,2,3-dithiazoles

4,5-Dichloro-1,2,3-dithiazolium chloride 1 condenses with active methylene compounds, such as malononitrile, barbituric acid and Meldrum’s acid, to give the dithiazol-5-ylidene derivatives, such as 3, 4 and 5, in modest yields. Better yields are obtained from 4-chloro-1,2,3-dithiazole-5-thione 6. Thus the thione 6 condenses with diphenyldiazomethane in a very mild version of the Barton double extrusion synthesis of hindered alkenes; this requires neither heat to extrude nitrogen nor a phosphine to abstract sulfur, to give the alkene 7 (83%) (Scheme 1). This alkene rearranges at room temperature, with loss of hydrogen chloride and sulfur, to give the benzothiophene 13 (89%) in a new thiophene ring-forming reaction (Scheme 2). The thione 6 also condenses with tetracyanoethylene oxide to give a better yield of the dicyanomethylene compound 3 (70%) (Scheme 4). Compound 3, in turn, reacts with morpholine and with chloride ions (Scheme 5) to give 3-morpholino-19 (60%) and 3-chloro- 20 (100%) isothiazole-4,5-dicarbonitrile, in a new isothiazole ring synthesis. Mechanisms are proposed for all of these reactions.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 1775-95-7. Formula: C13H10N2O3.

ELECTROCHEMICAL REDUCTION OF SUBSTITUTED ISOTHIAZOLE-3-THIONES IN APROTIC MEDIA

The title compounds are obtained in good yields from 1,2-dithiole-3-thiones. Using cyclic voltammetry in dimethylformamide, two kinds of behaviour are evidenced and discussed in terms of the aromaticity of the 5-substituent (Ar). With Ar = pyrazinyl or pyridazinyl, isothiazole-3-thiones undergo an electrochemical chemical electrochemical mechanism and the rate constant of the chemical step has been deduced from voltammetric measurements. When the aromaticity increases (Ar = pyridyl or phenyl) an apparent one-step irreversible two-electron addition occurs. Whatever the nature of Ar the resulting two-electron reduction product has been isolated after controlled-potential electrolysis (CPE). In addition, in acetonitrile, CPE affords a thiophene derivative as a secondary product.

Quantum-Chemical Investigation of Azoles 1. Alternative Electrophilic Substitution Mechanisms in 1,2-and 1,3-Azoles

Quantum-chemical calculations were performed for the molecular structures of 1,2-azoles (pyrazole, isoxazole, isothiazole), 1,3-azoles (imidazole, oxazole, thiazole), and the corresponding intermediates of electrophilic substitution reactions (with protons as the model electrophiles): azolium ions, bipolar ions (ylides/carbenes), cationic sigma-complexes, as well as activation energy values were calculated for the decomposition of ylides. The calculations were performed for gas phase and aqueous solutions according to the B3LYP method in a 6-31G(d) basis set, with corrections for the zero-point vibration energy. The solvation effects were taken into account by using the overlapping spheres model (IEFPCM). The results of the calculations explained some features of electrophilic substitution in azoles according to two alternative mechanisms: the classical addition-elimination with cationic sigma-complex intermediates, and the mechanism of elimination-addition that involves ylides (carbenes) as key intermediates.

Synthetic Route of 4397-53-9, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 4397-53-9.

The electronic states of thiazole studied by VUV absorption spectroscopy and ab initio configuration interaction methods

The thiazole VUV absorption spectrum over the range 5-12 eV shows intense bands near 5.4, 6.0, 7-7.8, 8.2-8.8, 9.2-10.1 and 10.2-11.0 eV; there is marked vibrational structure in the 7.5-8.5 and 10.2-11 eV regions. A number of Rydberg states have been identified, largely from IE1, but also tentative values for ones from IE2 and IE4. Electronic excitation energies for valence and Rydberg-type states have been computed using ab initio multi-reference multi-root CI methods, and these have been compared with the VUV envelope. Calculated energies for low-lying Rydberg states are close to those expected, and there is generally a good correlation between the theoretical intensities and calculated density of states, with the experimental envelope. The Cl studies used a triple zeta + polarization basis set, augmented by diffuse (Rydberg) orbitals. The lowest absorption bands are dominated by intense pi pi* (A ‘) valence states, together with LPN pi* and pi sigma* states, which are relatively weak. The lowest Rydberg states arise from excitation of the occupied MOs in the sequential order pi(4) < sigma(18) (LPN) < pi(3) < pi(2) < sigma(17) (LPs) this same order is determined by CI for ionisation in the UV-PES spectrum. Adiabatic structures of the sigma- and pi-triplets, -cations and the pi-anion have been compared with the ground state structure. The known phosphorescence of thiazole is from the (3)A triplet state (C-1 symmetry) where significant twisting of C5H and S to opposite sides of the mean plane occurs. Some theoretical molecular properties of thiazole are described, which give good agreement with microwave spectral data. (c) 2007 Elsevier B.V. All rights reserved. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6315-52-2, in my other articles.
