THE MICROWAVE-SPECTRUM OF THE ISOTHIAZOLE-ARGON VAN-DER-WAALS COMPLEX

Using molecular beam Fourier transform microwave spectroscopy I:measured and assigned the rotational spectra of the S-32- and (34)-isothiazole-argon complexes. The rotational constants are A’ = 3479.53543(15) MHz, B’ = 1225.68820(9) MHz, and C’ = 1154.69246(11) MHz for S-32-isothiazole-argon and A’= 3428.10063(23) MHz, B’ = 1216.56872(19) MHz, and C’= 1140.87783(24) MHz for the S-34-isotopomer. The N-14 quadrupole coupling constants X(aa) = 1.3824(17) MHz, X(bb) = 0.9126(17) MHz, X(cc) = -2.2951(17) MHz, and /x(bc)/ = 2.804(35) MHz could be extracted from the analysis of the spectra. For the S-34-isotopomer I derived x(aa)=1.3907(17)MHz, X(bb)=0.9242(20), X(cc) = -2.3148(20)MHz, and /X(bc)/ = 2.829(55)MHz. The spectroscopic constants were used to propose a structure of the isothiazole-argon van der Waals complex. The argon atom is located 3.55 Angstrom above the ring plane.

COMPARATIVE-STUDY OF AROMATICITY IN 5-MEMBERED RINGS CONTAINING S, SO AND SO2 GROUPS

Owing to the importance of the concept of aromaticity, different indices have been developed to try to quantify this property. The possible pi-delocalization through an X-SOn-X group (X = C, N; n = 0, 1 or 2) could explain heteroaromaticity in rings containing the moiety. For that reason, the aromaticity of five-membered sulphur-containing rings with different oxidation numbers (S, SO and SO2) and including no (thiophene), one (isothiazole) or two (1,2,5-thiadiazole) adjacent atoms was investigated. Ab initio calculations were carried out to determine geometrical parameters (planarity of the ring, bond length and bond order), electronic structure (charge distribution and dipolar moment) and the participation of d-orbitals of sulphur. According to these calculations, only compounds with S(II) can be considered to be aromatic, whereas compounds bearing S(IV) or S(VI) are better described as ylides.

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 80-07-9, in my other articles.

Non-nucleoside inhibitors of HCV polymerase NS5B. Part 4: Structure-based design, synthesis, and biological evaluation of benzo[d]isothiazole-1,1-dioxides

A series of benzo[d]isothiazole-1,1-dioxides were designed and evaluated as inhibitors of HCV polymerase NS5B. Structure-based design led to the incorporation of a high affinity methyl sulfonamide group. Structure-activity relationship (SAR) studies of this series revealed analogues with submicromolar potencies in the HCV replicon assay and moderate pharmacokinetic properties. SAR studies combined with structure based drug design focused on the sulfonamide region led to a novel and potent cyclic analogue. (C) 2009 Elsevier Ltd. All rights reserved.

Antipoliovirus activity and mechanism of action of 3-methylthio-5-phenyl-4-isothiazolecarbonitrile

Our previous studies described the synthesis and the antiviral activity of 3,4,5-trisubstituted isothiazole derivatives that were found to be particularly effective against enteroviruses. Compound 3-methylthio-5-phenyl-4-isothiazolecarbonitrile (IS-2) exhibited an interesting anti-poliovirus activity with a high selectivity index. In the present study we investigated the mechanism of action of this compound. Studies on the time of IS-2 addition to poliovirus type 1 infected cells suggested that the compound may inhibit some early process of viral replication. In order to determine its mechanism of action, we evaluated the rate of attachment and internalization of purified [(3)H]uridine-labeled poliovirus to HEp-2 cells in the presence or absence of IS-2. No effect on poliovirus adsorption and internalization to host cells was detected. We also investigated the influence of the compound on virus uncoating using labeled poliovirus and measuring the radioactivity of oligoribonucleotides formed from viral RNA susceptible to ribonuclease. These experiments demonstrated that poliovirus uncoating is influenced by IS-2 action. (C) 2010 Elsevier B.V. All rights reserved.

Isothiazoles in the Design and Synthesis of Biologically Active Substances and Ligands for Metal Complexes

The chemistry of isothiazoles is being intensively developed, which is evidenced by the wide range of selective transformations involving the isothiazole heterocycle and the high biological activity of its derivatives that can be used as effective new drugs and plant protection chemicals. Some representatives of isothiazoles have proven to be synergists of bioactive substances, which opens the way to lower the doses of drugs used and is especially important in cancer chemotherapy. In the framework of the present review, the accomplishments in the chemistry of isothiazoles over the past 18 years are examined, whilst current strategies for the synthesis of isothiazole-containing molecules and key directions of studies in this field of heterocyclic chemistry are discussed. Considerable attention is paid to chlorinated isothiazoles and strategies for their use in the synthesis of biologically active substances.

THE SYNTHESIS OF SUBSTITUTED IMIDAZO[4,5-D]ISOTHIAZOLES VIA THE RING ANNULATION OF ISOTHIAZOLE DIAMINES – AN INVESTIGATION OF THE CHEMICAL, PHYSICAL, AND BIOLOGICAL PROPERTIES OF SEVERAL NOVEL 5/5 FUSED ANALOGS OF THE PURINE RING-SYSTEM

A series of imidazo[4,5-d]isothiazoles have been prepared from isothiazole precursors via a strategy employing ring annulation of the appropriate isothiazole diamine. In this manner, several 4,5-diaminoisothiazoles were converted into the corresponding 5-(alkylthio)imidazo[4,5-d]isothiazoles via a two-step, one-pot procedure in good yield. This methodology proved quite general and allows for the introduction of various substituents onto the 3-, 5-, and 6-positions of this ring system. Reaction with Raney nickel destroyed the ring system, presumably through removal of the sulfur at the 1-position, and the 5-mercapto substituent could not be removed selectively. Ring annulation with diethoxymethyl acetate provided the 5-unsubstituted imidazo[4,5-d]isothiazoles but was less general, and only the 3-methyl derivatives could be prepared. Imidazo[4,5-d]isothiazoles bearing no substituents on nitrogen readily underwent alkylation to afford mixtures of the N-4- and N-6-substituted compounds. The chemical and physical properties of these novel heterocycles were studied in detail, and the structure of 3-methyl-5-methanesulfonyl-6-(phenylmethyl)imidazo[4,5-d] isothiazole was verified by single crystal X-ray diffraction studies.
