Isothiazolinone Biocides: Chemistry, Biological, and Toxicity Profiles

The importance of isothiazole and of compounds containing the isothiazole nucleus has been growing over the last few years. Isothiazolinones are used in cosmetic and as chemical additives for occupational and industrial usage due to their bacteriostatic and fungiostatic activity. Despite their effectiveness as biocides, isothiazolinones are strong sensitizers, producing skin irritations and allergies and may pose ecotoxicological hazards. Therefore, their use is restricted by EU legislation. Considering the relevance and importance of isothiazolinone biocides, the present review describes the state-of-the-art knowledge regarding their synthesis, antibacterial components, toxicity (including structure-activity-toxicity relationships) outlines, and (photo)chemical stability. Due to the increasing prevalence and impact of isothiazolinones in consumer’s health, analytical methods for the identification and determination of this type of biocides were also discussed.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 582-24-1, you can contact me at any time and look forward to more communication. Formula: C8H8O2.

THE SYNTHESIS OF SEVERAL IMIDAZO[4,5-D]ISOTHIAZOLES – DERIVATIVES OF A NEW RING-SYSTEM

Several derivatives of the new imidazo[4,5-d]isothiazole ring system have been synthesized from the appropriately substituted isothiazolediamines. The reaction of 3-methyl-4,5-diaminoisothiazole (4a) with diethoxy-methyl acetate gave a low yield of 3-methylimidazo[4,5-d]isothiazole (5a). However, the analogous reaction of 4,5-diaminoisothiazole (4b) with diethoxymethyl acetate failed to yield the parent imidazo[4,5-d]isothiazole ring system. The diamines 4a and 4b were readily cyclized with thiocarbonyldiimidazole to give the unstable thiones 6a and 6b, which were alkylated in situ to afford good yields of the corresponding 5-methylthioimidazo[4,5-d]isothiazoles 7a and 7b, respectively. Neither of these compounds could be reduced to the corresponding 5-unsubstituted derivatives via treatment with Raney nickel. To the best of our knowledge, this is the first report of the imidazo[4,5-d]isothiazole ring system.

Isothiazoles. Part XV. A mild and efficient synthesis of new antiproliferative 5-sulfanylsubstituted 3-alkylaminoisothiazole 1,1-dioxides

5-Sulfanyl-3-alkylaminoisothiazole dioxide derivatives have been identified as a new class of potent inhibitors of rat aortic myocite proliferation. They were prepared by applying a simple methodology able to introduce a heteroatom on C-5 of the 3-alkylaminoisothiazole dioxide system. 3-Aminosubstituted-5-chloroisothiazole dioxides react smoothly not only with S-nucleophiles but also with N- and O-nucleophiles affording the corresponding 5-heterosubstituted isothiazole dioxides through an addition-elimination reaction. The behavior of 3-alkylamino-4-bromo-isothiazole 1,1-dioxide with S-, N- and O-nucleophiles affording the same products has also been described. On the contrary, the 3amino-4,5-unsubstituted isothiazole dioxide system reacts easily only with sulfur nucleophiles affording the corresponding 4,5-dihydro-5 -sulfanylderivatives through a simple Michael addition reaction.

Macrocyclic prolinyl acyl guanidines as inhibitors of beta-secretase (BACE)

The synthesis, evaluation, and structure-activity relationships of a class of acyl guanidines which inhibit the BACE-1 enzyme are presented. The prolinyl acyl guanidine chemotype (7c), unlike compounds of the parent isothiazole chemotype (1), yielded compounds with good agreement between their enzymatic and cellular potency as well as a reduced susceptibility to P-gp efflux. Further improvements in potency and P-gp ratio were realized via a macrocyclization strategy. The in vivo profile in wild-type mice and P-gp effects for the macrocyclic analog 21c is presented.

CONDENSATION OF MUSCIMOL OR THIOMUSCIMOL WITH AMINOPYRIDAZINES YIELDS GABA-A ANTAGONISTS

Ten analogs of muscimol and thiomuscimol in which the amino function was delocalized in an amidinic system were prepared by N2 alkylation of 6-aryl-3-aminopyridazines with (chloromethyl) isoxazole or (chloromethyl)isothiazole derivatives. These muscimol and thiomuscimol derivatives show potent binding properties for GABA-A receptors (they displace [H-3]GABA and [H-3]gabazine) and provoke convulsions after iv injections. They fit well with the model pharmacophore proposed by our group for the GABA-A antagonists and show similar structure-activity profiles to that of the pyridazinyl-GABAs.

The concerted and stepwise chemisorption mechanisms of isothiazole and thiazole on Si(100)-2 x 1 surface

The surface reaction pathways of isothiazole and thiazole on Si(100)-2 x 1 surface were theoretically investigated using multireference wavefunctions. In the case of isothiazole, the Si-N dative adduct turned out to be the major surface product. In contrast, a direct reaction competition between a concerted [4 + 2](CC) cycloaddition and Si-N dative adduct was found in the adsorption of thiazole. Therefore, it is concluded that the particular geometric arrangements of heteroatoms exhibit distinctly different initial surface reaction mechanisms.

Ibotenic acid and thioibotenic acid: a remarkable difference in activity at group III metabotropic glutamate receptors

In this study, we have determined and compared the pharmacological profiles of ibotenic acid and its isothiazole analogue thioibotenic acid at native rat ionotropic glutamate (iGlu) receptors and at recombinant rat metabotropic glutamate (mGlu) receptors expressed in mammalian cell lines. Thioibotenic acid has a distinct pharmacological profile at group III mGlu receptors compared with the closely structurally related ibotenic acid; the former is a potent (low mum) agonist, whereas the latter is inactive. By comparing the conformational energy profiles of ibotenic and thioibotenic acid with the conformations preferred by the ligands upon docking to mGlu(1) and models of the other mGlu subtypes, we propose that unlike other subtypes, group III mGlu receptor binding sites require a ligand conformation at an energy level which is prohibitively expensive for ibotenic acid, but not for thioibotenic acid. These studies demonstrate how subtle differences in chemical structures can result in profound differences in pharmacological activity. (C) 2004 Elsevier B.V. All rights reserved.
