Naphtho[1,2-d]isothiazole acetic acid derivatives as a novel class of selective aldose reductase inhibitors

Acetic acid derivatives of naphtho[1,2-dlisothiazole (NiT) were synthesized and tested as novel aldose reductase (ALR2) inhibitors. The parent compound 11 exhibited a fair inhibitory activity (IC50 = 10 mu M), which was enhanced by 2 orders of magnitude by introducing a second carboxylic group at position 4 (13 and 14: IC50 = 0.55 and 0.14 mu M, respectively). Substitution of the acetic acid function with an apolar group gave inactive (29) or poorly active (25, 26, 30) compounds, thus demonstrating that the 2-acetic group is involved in the enzyme pharmacophoric recognition while the 4-carboxylic moiety has only an accessory role. The potent compounds 11, 13, 14, 26 all proved to be selective for ALR2, since none of them inhibited aldehyde reductase, sorbitol dehydrogenase, or glutathione reductase. The isopropyl. ester 31, a prodrug of 14, was found to be effective in preventing cataract development in severely galactosemic rats, when administered as an eyedrop solution. The theoretical binding mode of 13 and 14, obtained by docking simulations into the ALR2 crystal structure, was fully consistent with the structure-activity relationships in the NiT series.

An efficient synthesis and biological screening of benzofuran and benzo[d]isothiazole derivatives for Mycobacterium tuberculosis DNA GyrB inhibition

A series of twenty eight molecules of ethyl 5-(piperazin-1-yl)benzofuran-2-carboxylate and 3-(piperazin-1-yl)benzo[d]isothiazole were designed by molecular hybridization of thiazole aminopiperidine core and carbamide side chain in eight steps and were screened for their in vitro Mycobacterium smegmatis (MS) GyrB ATPase assay, Mycobacterium tuberculosis (MTB) DNA gyrase super coiling assay, antitubercular activity, cytotoxicity and protein-inhibitor interaction assay through differential scanning fluorimetry. Also the orientation and the ligand-protein interactions of the top hit molecules with MS DNA gyrase B subunit active site were investigated applying extra precision mode (XP) of Glide. Among the compounds studied, 4-(benzo[d]isothiazol-3-yl)-N-(4-chlorophenyl)piperazine-1-carboxamide (26) was found to be the most promising inhibitor with an MS GyrB IC50 of 1.77 +/- 0.23 mu M, 0.42 +/- 0.23 against MTB DNA gyrase, MTB MIC of 3.64 mu M, and was not cytotoxic in eukaryotic cells at 100 mu M. Moreover the interaction of protein-ligand complex was stable and showed a positive shift of 3.5 degrees C in differential scanning fluorimetric evaluations. (C) 2014 Elsevier Ltd.

NAD(P)H Quinone Oxidoreductase 1 (NQO1)-Bioactivated Pronqodine A Regulates Prostaglandin Release from Human Synovial Sarcoma Cells

Natural products have contributed to the elucidation of biological mechanisms as well as drug discovery research. Even now, the expectation for natural products is undiminished. We screened prostaglandin release inhibitors that had no effect on in vitro cyclooxygenase activity derived from natural product sources and discovered pronqodine A. Using spectral analysis and total synthesis, the structure of pronqodine A was shown to be a benzo[d]isothiazole-4,7-dione analogue. Evaluation of the biological activity of pronqodine A revealed that the NAD(P)H dehydrogenase quinone 1 (NQO1) converted pronqodine A into a two-electron reductive form. The reductive form underwent autoxidation and reversed to its native form immediately with the generation of reactive oxygen species. Further investigations proved that pronqodine A inhibited cyclooxygenase enzyme activity only in the presence of NQO1. Pronqodine A acts as a potential bioreductive compound, inhibiting prostaglandin release in selectively activated NQO1-expressing cells.

SYNTHESIS OF DE NOVO CHIRAL gamma-AMINO-YNAMIDES USING LITHIATED YNAMIDES. OBSERVATION OF A UNIQUE 5-ENDO-DIG CYCLIZATION WITH AN INVERSION OF S-CENTER

We describe herein details of our efforts in developing a highly stereoselective synthesis of de novo chiral gamma-amino-ynamides through additions of lithiated ynamides to Ellman-Davis chiral N-tert-butanesulfinyl imines While additions of ynamides could be highly stereoselective even without Lewis acids, the use of BF3-OEt2 completely reversed the stereo selectivity. On the other hand, additions of oxazolidinone-substituted, oxazinanone-substituted and tetrahydropyrimidinone-substituted ynamides behaved quite differently and functioned better with BF3-OEt2. The chirality of the oxazolidinone ring exerts no impact on the selectivity. This work also features a unique 5-endo-dig cyclization of oxazolidinone-substituted gamma-amino-ynamides that could be promoted with acid, leading to isothiazoles and 2,3-dihydro-isothiazole S-oxides.

Tandem Photoarylation-Photoisomerization of Halothiazoles: Synthesis, Photophysical and Singlet Oxygen Activation Properties of Ethyl 2-Arylthiazole-5-carboxylates

The photochemical reaction between ethyl 2-chlorothiazole-5-carboxylate and benzene gave no product. In contrast, the reaction with ethyl 2-iodothiazole-5-carboxylate gave ethyl 3-phenylisothiazole-4-carboxylate. The same behaviour was observed if the reaction was performed in the presence of furan, thiophene and 2-bromothiophene. The products thus obtained were studied for their photophysical properties and it was found that the observed absorptions [lambda(max)=257 nm (epsilon = 7000 M-1 cm(-1)) for ethyl 3-phenylisothiazole-4-carboxylate, 278 nm (a = 7000 M-1 cm(-1)) for ethyl 3-(2-furyl)isothiazole-4-carboxylate, 269 and 285 nm (a = 7500 M-1 cm(-1)) for ethyl 3(2-thienyl)isothiazole-4-carboxylate] are mainly due to pi -> pi* transitions from the HOMO to the LUMO+1 orbital. The tested compounds showed fluorescence [lambda(em) = 350-400 (lambda(exc) = 300 nm), 360 and 410 nm (lambda(exc) = 320 nm), 412 nm (lambda(exc) 340 nm) for ethyl 3-phenylisothiazole-4-carboxylate, 397 and 460 nm (lambda(exc) = 300 nm), 381, 394 and 460 nm (lambda(exc) = 320 nm), 381, 398 and 466 rim (lambda(exc) = 340 nm) for ethyl 3-(2-furyl)isothiazole-4-carboxylate, 372, 377 and 414 nm (lambda(exc) = 300, 320 and 340 nm respectively) for ethyl 3-(2-thienyl)isothiazole-4carboxylate], possibly due to dual emission from different excited states. The use of the compound obtained as a sensitizer in the photo-oxidation of trans-alpha,alpha’-dimethylstilbene showed that all the new compounds are singlet-oxygen sensitizers.
