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.

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.

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.

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.

Rhodium-Catalyzed Annulative Coupling of Isothiazoles with Alkynes through N-S Bond Cleavage

A Rh(III)-catalyzed annulative coupling of 3,5-diarylisothiazoles and alkynes is reported. The N-S bond in the isothiazole ring acts as an internal oxidant to regenerate the Rh(III) species in combination with an external Cu(II) oxidant, and the corresponding 1:2 coupling products are obtained. The remarkable difference in the reaction outcome between isothiazoles and the relevant isoxazoles has been investigated by DFT calculations, revealing that the relative stability of the enolate intermediates dictates the product selectivity.
