Structural, topological and vibrational properties of an isothiazole derivatives series with antiviral activities

In this work, the structural, topological and vibrational properties of an isothiazole derivatives series with antiviral activities in gas and aqueous solution phases were studied by using OFT calculations. The self consistent reaction field (SCRF) method was combined with the polarized continuum (PCM) model in order to study the solvent effects and to predict their reactivities and behaviours in both media. Thus, the 3-mercapto-5-phenyl-4-isothiazolecarbonitrile (I), 3-methylthio-5-phenyl-4-isothiazolecarbonitrile (II), 3-Ethylthio-5-phenyl-4-isothiazolecarbonitrile (III), S-[3-(4-cyano-5-phenyl)isothiazolyl] ethyl thiocarbonate (IV), 5-Phenyl-3-(4-cyano-5-phenylisothiazol-3-yl) disulphany1-4-isothiazolecarbonitrile (V) and 1,2-Bis(4-cyano-5-phenylisothiazol-3-yl) sulphanyl Ethane (VI) derivatives were studied by using the hybrid B3LYP/6-31G* method. All the properties were compared and analyzed in function of the different R groups linked to the thiazole ring. This study clearly shows that the high polarity of (I) probably explains its elevated antiviral activity due to their facility to traverse biological membranes more rapidly than the other ones while in the (IV) and (V) derivatives the previous hydrolysis of both bonds increasing their antiviral properties inside the cell probably are related to their low S-R bond order values. In addition, the complete vibrational assignments and force constants are presented. (C) 2015 Elsevier B.V. All rights reserved.

In silico ligand-based (LB) and docking-based (DB) 3D-QSAR study of potent Chk2 inhibitors

Isothiazole carboxamidine compounds are potent ATP competitive Chk2 inhibitors. A series of compounds with Chk2 inhibitory activity were taken from literature and different 3D-QSAR models have been generated with Comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (COMSIA). In first scheme LB-QSAR models were generated using fully optimized geometries by PM3 approach giving reasonable statistics of CoMFA (q(2)=0.88, r(2)=0.96 and r(predictive)(2) = 0.60) and CoMSIA(q(2)=0.918 r(2)=0.99 and r(predictive)(2) = 0.55). In second and third scheme the ligands 7 docked in to receptor protein (PDB 2CN8). Consequently, two most plausible modes were identified and used as initial templates. The docked conformer based CoMFA model shows good correlation with activity (q(2)=0.91, r2=0.99 and r(predictive)(2) =0.84). Whereas in CoMSIA, the steric and hydrophobic and donor field jointly give a better statistics (q(2)=0.92 r(2)=0.99 and r(predictive)(2) =0.53). These findings might be helpful to design more potent Chk2 inhibitors.

Potent Inhibitors of Acetyltransferase Eis Overcome Kanamycin Resistance in Mycobacterium tuberculosis

A major cause of tuberculosis (TB) resistance to the aninoglycoside kanamycin (KAN) is the Mycobacterium tuberculosis (Mtb) acetyltransferase Eis. Upregulation of this enzyme is responsible for inactivation of KAN through acetylation. of its amino;groups. A 123 000 compound high-throughput screen (HTS);yielded several small-molecule Eis inhibitors 014 share an isothiazole S,S-dioxide hoteroeyelic core. TheSe were investigated for their, structure attiliity relationships.: Crystal structures of Eis in,complex with two potent inhibitorS show that these molecules are bound in the conformationally :adaptable aminoglycoSide binding site of the enzyme, thereby obstructing binding of KAN for acetylation. Importantly; we demonstrate that several Eis inhibitors, when used in combination with KAN against resistant Mtb, efficiently overcome KAN resistance. This approach paves the way:toward development of novel combination, thetapies against aminoglycoside-resistant TB.

Isothiazole dioxide derivative 6n inhibits vascular smooth muscle cell proliferation and protein farnesylation

Isothiazole dioxides have been shown to inhibit Trypanosoma brucei protein. farnesyltransferase (PFTase) in isolated enzyme, but elicited only a minor effect on mammalian PFTase. In the present study we have evaluated the effect of 3-diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxides with different substituents at C5, on rat PFTase and protein geranylgeranyltransferase-I (PGGTase-1) with the final aims to improve the potency against mammalian PFTase and to identify new compounds with antiproliferative properties. For these purposes, in vitro and cell culture models have been utilized. The results showed that isothiazole dioxides with C4-C5 double bond and sulfaryl substituted at the C5 position but none of the dihydro-derivatives, were able to inhibit in vitro PFTase in a concentration dependent manner (IC50 ranging from 8.56 to 1015 mu M). Among those, compound 6n (C5; methyl-S) displayed 500-fold higher inhibitory potency on PFTase than PGGTase-1. Compound 6n was shown to affect rat smooth muscle cell (SMC) proliferation at concentrations similar (IC50 = 61.4 mu M) to those required to inhibit [H-3]-farnesol incorporation into cellular proteins (-44.1% at 100 mu M). Finally, compound 6n interferes with rat SMC proliferation by blocking the progression of G0/G1 phase without inducing apoptosis, as assessed by [H-3]-thymidine incorporation assay and flow cytometry analysis. Taken together, we described a new PFTase inhibitor containing the isothiazole dioxide moiety that affects mammalian protein farnesylation and SMC proliferation by inhibiting G0/ G1 phase of the cell cycle.

Rational design of diketopyrrolopyrrole-based multifunctional materials for organic light-emitting diodes and organic solar cells

A series of donor-acceptor diketopyrrolopyrrole derivatives has been investigated to reveal their optical, electronic, and charge transport properties for applications in organic light-emitting diodes (OLEDs) and organic solar cells (OSCs). The calculated results show that their optical, electronic, and charge transport properties are affected by the different end groups. The introduction of the 2,5-diphenylthiophene, benzo[c]isothiazole, benzo[c]thiophene, benzo[c]thiophene, 2,4-dihydrobenzo[d]thiazole, and thieno[3,4-b][1,4] dioxine end groups can broaden absorption spectrum and improve charge transport property of the designed compounds. Our results suggest that the designed compounds can serve as donor materials for OSCs and luminescent materials for OLEDs. In addition, the mobility of the designed compounds is also investigated. They are expected to be promising candidates for hole and electron transport materials. On the basis of investigated results, we proposed a rational way for the design of multifunctional materials for OLED and OSC applications.

INVITRO ANTIVIRAL ACTIVITY OF 4 ISOTHIAZOLE DERIVATIVES AGAINST POLIOVIRUS TYPE-1

The in vitro effects of four isothiazoles [5,5′-diphenyl-3,3′-diisothiazole disulfide, 5-phenyl-3-mercapto-isothiazole, 5,5′-(4-chlorophenyl)-3,3′-diisothiazole disulfide, and 5-(4-chlorophenyl)-3-mercapto-isothiazole] on poliovirus type 1 were studied. The derivatives tested demonstrated remarkable viral inhibition, with a higher selectivity index than the previously studied iminodithiole precursors. Under one-step growth conditions, all the isothiazole derivatives caused the greatest activity if added during or after (within 1 h) pollovirus adsorption. These data suggest interference with early events of viral replication. [5-H-3]Uridine incorporation into RNA showed that the compounds tested reduced pollovirus RNA synthesis, which was completely shut off after 2 h of incubation and reduced by 50-60% after 4 h. Also, pretreatment of the cell cultures with the compounds for 24 h caused a substantial inhibition of viral replication. The data suggest that the four isothiazole derivatives may have a multi-step antiviral mode of action different from their iminodithiole precursors.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 91-10-1. Category: isothiazole.

Synthesis of Fluorine-Containing Derivatives of 5-Arylisoxazoles and 4,5-Dichlorothiazole

Alkylation of fluorophenols and phenolic aldehydes with 5-phenyl(p-tolyl)-3-chloromethylisoxazole under the Williamson reaction conditions afforded the corresponding ethers. Condensation of the resulting phenolic aldehyde derivatives and 5-phenyl(p-tolyl)isoxazole-3-carbaldehydes with p-fluoroaniline resulted in fluorine-containing azomethines. Acylation of fluorinated amines with 5-(p-tolyl)isoxazole- and 4,5- dichloroisothiazole-3-carbonyl chlorides gave rise to fluorinated amides bearing isoxazole and isothiazole fragments, representatives of which showed a synergistic effect in compositions with insecticides.

The infrared spectrum of isothiazole in the range 600-1500 cm(-1), including a high-resolution study of the v(11)(A ‘) band at 818cm(-1) and the v(16)(A ”) band at 727cm(-1), together with ab initio studies of the full spectrum

The gas-phase high-resolution infrared spectrum of isothiazole in the range 600-1500 cm(-1) has been recorded, and revised band centres obtained for a number of vibrations. An analysis of the nu(11)(A’) band at 818 cm(-1) and the nu(16)(A) band at 727cm(-1) has been performed, using the Watson Hamiltonian, A-reduction, IIIr representation. These were combined with previous microwave spectral data to provide combined analyses for rotational constants and quartic centrifugal distortion constants Delta(J), Delta(JK), Delta(K), delta(J) and delta(K). These extend the knowledge derived from previous microwave and IR spectral studies. The equilibrium structures and the derived harmonic frequencies were calculated by ab initio methods, using a variety of basis sets with MP2, MP4 and CCSD(T) methods, and a comparison of these with experimental data is discussed. At a pragmatic level, the closest correlation of the rotational constants with experiment is not obtained with the most sophisticated methodology. Similarly, the vibration frequencies and intensities also vary strongly with the procedure. In particular, we found that the cc-pVTZ + MP2 results probably provide the best numerical comparison with experimental IR data for this molecule.
