Benzo[d] isothiazole 1,1-dioxide derivatives as dual functional inhibitors of 5-lipoxygenase and microsomal prostaglandin E-2 synthase-1

A series of 6-nitro-3-(m-tolylamino) benzo[d] isothiazole 1,1-dioxide analogues were synthesized and evaluated for their inhibition activity against 5-lipoxygenase (5-LOX) and microsomal prostaglandin E-2 synthase (mPGES-1). These compounds can inhibit both enzymes with IC50 values ranging from 0.15 to 23.6 mu M. One of the most potential compounds, 3g, inhibits 5-LOX and mPGES-1 with IC50 values of 0.6 mu M, 2.1 mu M, respectively. (C) 2014 Elsevier Ltd. All rights reserved.

Synthesis of Isothiazole via the Rhodium-Catalyzed Transannulation of 1,2,3-Thiadiazoles with Nitriles

A synthetic method for obtaining a wide variety of isothiazoles by the Rh-catalyzed transannulation of 1,2,3-thiadiazoles with alkyl, aryl, and heteroaryl nitriles, which proceeds via an alpha-thiavinyl Rh-carbenoid intermediate, was developed. The results suggest that during its reaction with nitriles, the alpha-thiavinyl carbene acts as an umpolung 1,3-dipole equivalent, in contrast to its behavior during its reaction with alkynes. The developed method was successfully employed to synthesize pentaoligomeric arylene compounds consisting of three benzene and two isothiazole rings.

The 5-hydrazino-3-methylisothiazole-4-carboxylic acid, its new 5-substituted derivatives and their antiproliferative activity

Currently, the basic method of treatment of colon cancer is surgery. The range of anticancer drugs used in the treatment of colorectal cancer is small and is based mainly on systemic combination chemotherapy. As a result of the designed syntheses, we received new isothiazole derivatives with anticancer activity. The synthesized 5-hydrazino-3-methylisothiazole-4-carboxylic acid has never been obtained before. It is also a substrate for the synthesis of its innovative derivatives, i.e. compounds that are Schiff bases. The identification of the structure of new compounds was carried out using mass spectrometry (MS), proton nuclear magnetic resonance spectroscopy (H-1 NMR), carbon nuclear magnetic resonance spectroscopy (C-13 NMR) and infrared spectroscopy (IR). Potential antitumor activity was confirmed in antiproliferative MTT and SRB tests. The selected, most biologically active substances were characterized by high selectivity towards leukemia and colon cancer cell lines. They caused high inhibition of proliferation of human biphenotypic B cell myelomonocytic leukemia MV4-11 (13 compounds), human colon adenocarcinoma cell lines sensitive LoVo (8 compounds) and resistant to doxorubicin LoVo/DX (12 compounds). However, in the conducted studies, their activity against breast adenocarcinoma MCF-7 and normal non-tumorigenic epithelial cell line derived from mammary gland MCF-10A was substantially lower. The result of this work is claimed Polish patent application.

ANTIPOLIOVIRUS ACTIVITY OF ISOTHIAZOLE DERIVATIVES – MODE OF ACTION OF 5,5′-DIPHENYL-3,3′-DIISOTHIAZOLE DISULFIDE (DID)

In this report we describe the antiviral activity of 5,5′-diphenyl-3,3’diisothiazole disulfide (DID) and discuss its mode of action. DID selectively inhibits the replication of poliovirus type 1 (therapeutic index = 255) by affecting some early process of the virus growth cycle. The compound does not interfere with adsorption and internalization of virus to HEp-2 cells, nor with uncoating of the viral RNA. However, no viral RNA synthesis occurs after 2 h postinfection in the presence of 50 mu M DID. Thus, we investigated some molecular events in poliovirus replication occurring between uncoating and viral RNA synthesis. In our experimental design, we studied the activity of RNA polymerase complex isolated from HEp-2 infected cells in the presence or absence of DID. Our results showed that the RNA polymerase complex was formed in the presence of DID, On the contrary, DID markedly inhibited poliovirus RNA synthesis in a cell-free system using RNA polymerase complex isolated from infected cells. These findings indicate that DID may exert its antiviral activity by preventing viral RNA chain elongation via the inhibition of replicase activity and/or interfering with viral RNA polymerase complex.

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 22884-95-3. Application In Synthesis of 3,4-Dimethylbenzonitrile.

Fluorinated diazo diketones in rhodium(II)-catalyzed reactions with sultams: Chemoselective O-functionalization of amide carbonyl groups

Rhodium(II)-catalyzed decomposition of fluorinated diazo diketones in the presence of isothiazole-3(2H)-one 1,1-dioxides offers a chemoselective and useful tool for O-functionalization of their C=O groups by interaction with transient fluorine-containing Rh-II-diketocarbenoids. The resulting O-alkylimidates of isothiazole 1,1-dioxides, bearing (trifluoromethyl)acetyl groups, easily react with traces of H2O giving rise to stable hydrates of the perfluoroacetyl groups. No O -> N isomerization of O-alkylimidates (similar to the Lander-Chapman rearrangement) was observed under the reaction conditions studied.

Aza-substituted thiophene derivatives: Structures, dipole moments, and polarizabilities

Ab initio calculations of dipole moments and static dipole polarizabilities are reported for nine heteroaromatic five-membered rings-thiophene, thiazole, isothiazole, the four thiadiazoles, and the two thiatriazoles-all at their MP2/6-31G** geometries. Extensive basis sets have been used, and the approximate applicability of the variational principle to the Hartree-Fock polarizability has been discussed. Electron correlation effects have been investigated up to the MP4(SDQ) level for a representative subset of the series of the molecules considered. Our best polarizability determinations are expected to be accurate within a few percent.
