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. In addition, a comprehensive review of existing literature in the field of metal complexes of isothiazoles is given, including the results and prospects for the practical use of isothiazole-metal complexes as catalysts for cross-coupling reactions in aqueous and aqueous-alcoholic media (‘green chemistry’). 1 Introduction 2 Synthesis by Ring-Forming Reactions 2.1 Intramolecular Cyclization 2.2 (4+1)-Heterocyclization 2.3 (3+2)-Heterocyclization 2.4 Syntheses by Ring Transformations 3 Isothiazoles by Ring Functionalization Reactions: Nucleophilic Substitution, Cross-Coupling and Side-Chain Functionalization 4 Selected Syntheses of Biologically Active Isothiazole Derivatives 5 Isothiazoles in the Synthesis of Transition-Metal Complexes and in Metal-Complex Catalysis 6 Conclusion

In this paper we describe synthesis, structures and some physicochemical properties of 20 isothiazolopyridines 8-13 substituted differently into an isothiazole ring as well as their in vitro antibacterial assays against Mycobacterium tuberculosis H37Rv, Mycobacterium fortuitum PCM 672 and Propionibacterium acnes PCM 2400. Compound 13a was found to be the most active derivative against M. tuberculosis H37Rv, demonstrating 100% growth inhibition of microorganisms in the primary screen (minimum inhibitory concentration [MIC] 6.25 mu g/mL). Nineteen of the prepared compounds were evaluated against M. fortuitum PCM 672 and P. acnes PCM 2400 and only compounds 9 and 12d exhibited excellent activity against individual strains of microorganisms with MIC90 <1 mu g/mL. The inhibitory action of the remaining isothiazolopyridines towards the tested strains of the microorganism was low, absent, or a non-linear correlation prohibited accurate determination of MIC values. Unexpectedly, seven of the remaining isothiazolopyridines tested against M. fortuitum and P. acnes stimulated growth of the microorganisms in the range 10-50% or even more (10b) under experimental conditions.

Thirteen dyestuffs of four chemical classes (quinophthalone, anthraquinone, isothiazole-fused anthrone and pyridone azo) were applied for the dyeing of unmodified polypropylene fibres in supercritical carbon dioxide. From these 13 dyestuffs, three dyestuffs that have a pure yellow hue and good dyeability for polypropylene fibres were found. The results of a dyeability test using the 13 dyestuffs suggested that the affinity for polypropylene fibres requires, in the structural character of the dyestuff molecule, not only extreme hydrophobicity but also high aliphaticity. The isothiazole-fused anthrone nonanamide dyestuff and two types of N-butyl substituted pyridone azo dyestuffs were examined for build-up and colour fastness properties. The light fastness of the dyed fabric was not so good. The ratings of fastness to washing, perspiration and rubbing ranged from excellent to fairly good with the increase of the depth of shade. From the relationship between the build-up curve and the colour fastness, it was found that the dyestuff of the isothiazole-fused anthrone nonanamide is suitable for polypropylene dyeing in a pale or medium shade, and that the two types of N-butyl substituted pyridone azo dyestuffs are suitable in a deep shade.
