Discovery of Novel Piperidinylthiazole Derivatives As Broad-Spectrum Fungicidal Candidates

Oxathiapiprolin is one of the best active fungicides discovered for oomycetes control. To develop a fungicide candidate with a broad spectrum of activity, 22 new piperidinylthiazole derivatives were designed and synthesized. Compound 51 showed the best activity against Pseudoperonospora cubensis (Berk. et Curt.) Rostov and Phytophthora infestans in vivo with 100% and 80% of inhibition, respectively, at 1 mg/L, and 72.87% of field efficacy against P. cubensis at 1 g ai/667 m(2) validated these results. Compound 5i exhibited a broad spectrum of excellent activity against Sclerotinia sclerotiorum with EC50 = 0.30 mg/ L (>10 times more active than oxathiapiprolin and azoxystrobin in vitro), good activity against Botrytis cinerea, Cercospora arachidicola, and Gibberella zeae with EC50 of 14.54, 5.57, and 14.03 mg/L in vitro and against P. cubensis and P. infestans with 60% and 30% inhibition rates, respectively, at 1 mg/L in vivo. Mode of action studies by RNA sequencing analysis discovered oxysterol-binding protein (OSBP), chitin synthase (CHS1), and (1,3)-beta-glucan synthase (FKS2) as the potent target of 5i against S. sclerotiorum. Quenching studies validated that OSBP was the same target of both 5i and oxathiapiprolin; it was quenched by both of them. Our studies discovered isothiazole-containing piperidinylthiazole as an OSBP target-based novel lead for fungicide development.

Nitrile Sulfides Part 16.(1,2) Synthesis of 1,2-benzisothiazoles via nitrile sulfide cycloaddition reactions

The cycloaddition reactions of nitrile sulfides have been used to prepare benzisothiazole quinones and 1,2-benzisothiazole-5,6-dicarboxylates. The nitrile sulfides, generated by thermal decarboxylation of 1,3,4-oxathiazol-2-ones, reacted with 1,4-naphthoquinone to afford 3-substituted naphtho[2,3-d]isothiazole-4,9-diones (17), together with nitriles as by-products. The corresponding reactions with 1,4-benzoquinone yielded regioisomeric mixtures of 2: 1 adducts. The 1,2-benzisothiazole-5,6-dicarboxylates were synthesised by a sequence involving both nitrile sulfide and Diels-Alder cycloaddition reactions. Dimethyl 3-phenylisothiazole-4,5-dicarboxylate (34), prepared from benzonitrile sulfide and dimethyl acetylenedicarboxylate (DMAD), was converted into the 4,5-bis(dibromomethyl) analogue 37 via the bis(dihydroxymethyl) compound 35. Treatment of 37 with sodium iodide in the presence of DMAD afforded dimethyl 3-phenyl-1,2-benzisothiazole-5,6-dicarboxylate (30) via the isothiazole o-quinodimethane 32.

A reaction sequence involving transformations of 5-(4-methylphenyl)isoxazole and 4,5-dichloroisothiazole derivatives containing an amidoxime group at position 3 allowed to synthesize the respective 3,5-isoxazolyl(isothiazolyl)-substituted 1,2,4-oxadiazoles. Selective recyclization of 4,5-dichloro-3-(1De-tetrazol-5-yl)isothiazole and 5-(4-methylphenyl)-3-(1De-tetrazol-5-yl)isoxazole gave 2,5-isoxazolyl-(isothiazolyl)-substituted 1,3,4-oxadiazoles. The obtained compounds combining three azole heterocycles in one molecule formed palladium complexes that showed high catalytic activity in Suzuki reactions in aqueous and aqueous alcohol media.

A new monoclinic polymorph of 3-diethylamino-4-(4-methoxyphenyl)-1,1-dioxo-4H-1 lambda 6,2-thiazete-4-carbonitrile

A new monoclinic form of the title compound, C14H17N3O3S, has been found upon slow crystallization from water. Another monoclinic form of the compound was obtained previously from a mixture of dichloromethane and diethyl ether [Clerici et al. (2002). Tetrahedron, 58, 5173-5178]. Both phases crystallize in space group P2(1)/n with one molecule in the asymmetric unit. The formally single exocyclic C-N bond that connects the -NEt2 unit with the thiazete ring is considerably shorter than the adjacent, formally double, endocyclic C=N bond. This is likely to be due to the extended conjugated system between the electron-donor diethylammine fragment and the electron-withdrawing sulfonyl group. In the newly discovered polymorph, the methoxy group is rotated by almost 180 degrees around the phenyl-OCH3 bond, resulting in a different molecular conformation.

Synthesis and docking study of diaryl-isothiazole and 1,2,3-thiadiazole derivatives as potential neuroprotective agents

Neuroinflammation has been implicated in pathophysiology of many neurodegenerative diseases. The p38 MAP kinase signaling pathway and COX-1 have active roles in initiation and perpetuation of neuroinflammatory process which have deteriorating effects on neurons. In order to develop new anti-neuroinflammatory compounds some 4-aryl-5-(methylthiophen-2-yl) isothiazoles and 5-aryl-4-(methylthiophen-2-yl)-1,2,3-thiadiazoles were synthesized. Docking studies have revealed that these structures could be potential mutual inhibitors of p38 alpha and COX-1 and could be considered for neuroprotective effects. In order to assess CNS penetrability of these compounds, a QSAR model of blood-brain barrier penetration has been developed and LogBB of compounds has been predicted. All compounds showed LogBB as greater than zero which indicates their potential CNS penetrability.

Hypervalent S-Cl bond in cyclic acylaminochloro-lambda(4)-sulfanes: a comparison of N-S-Cl, N-S+ClO4- and N-S+center dot center dot center dot O=C bond systems

Two cyclic acylaminochloro-lambda(4)-sulfanes containing a five- or a six-membered hetero ring (5 and 6), as well as their cyclic acylaminosulfonium salt analogues without (7 and 8) and with S … O close contact (9 and 10), have been prepared and their molecular structures determined by X-ray diffraction. Compounds 5, 6, 9 and 10 exhibit a trigonal bipyramidal configuration about the central sulfur atom, with nitrogen and chlorine (in 5 and 6) or with nitrogen and oxygen atoms (in 9 and 10) in axial positions. In sulfonium salts 7 and 8, the bond angles about sulfur an similar to those obtained for analogous lambda(4)-sulfanes 5 and 6. The interatomic S-N distances, which range from 1.66 to 1.73 Angstrom, point to a strong covalent bond in an compounds investigated. In lambda(4)-sulfanes the axial S-Cl hypervalent bond (2.69 Angstrom in 5, 3.10 Angstrom in 6) is rather long and markedly polarized. In methoxycarbonyl-substituted acylaminosulfonium salts the interatomic S … O distances are 2.41 Angstrom (in 9) and 2.74 Angstrom (in 10). The individual S-N, S-Cl, S … O and S-C-ar bond lengths, as well as the N(ax)-S-X(ax) (X = Cl or O=), N(ax)-S-C-ar(eq), Cl(ax)-S-C-ar(eq) and C-ar(eq)-S-C-ar'(eq) bond angles (159-176 degrees, 90-104 degrees, 85-96 degrees and 101-104 degrees, respectively), which depend on both the axial substituents on sulfur and the size of the hetero ring, are compared and discussed. The five-membered 2,3-dihydro-isothiazole rings in 5, 7 and 9 are practically planar, whereas the 1,2-oxathiole ring in 10 is unusually puckered. The six-membered dihydro-1,2-thiazine rings in 6, 8 and 10, as well as the 1,2-oxathiine ring in 9, assume a more or less inverted half-chair form. The orientations of the aromatic rings in relation to the C-ar(eq)-S-C-ar'(eq) plane are also discussed. (C) 1999 Elsevier Science B.V. All rights reserved.

Additivity of substituent effects on the visible absorption spectra of some heteroarylazo compounds: the influence of solvent

Pronounced solvatochromic shifts are observed in the visible spectra of two series of heteroarylazobenzene derivatives based on m-acetylamino- and m-methyl-N,N-diethylaniline, measured in various solvents. The heteroaryl azo component of these dyes can be viewed as a thiophene ring substituted by cyano, nitro, alkoxycarbonyl, or ring aza (to give thiazole and isothiazole derivatives). Free-Wilson analysis has shown that the influence of each of the substituents is constant across all molecules within the two series for a given solvent. However, the substituent increments vary between different solvents and correlate with the Kamlet-Taft dipolarity/polarisability parameter pi* of the solvents. There appears to be no intuitive explanation for the relative solvent variation of different substituents, but Onsager theory suggests sensitivity to the relative size and shape of the dyes. Visible absorption maxima are predicted for unknown heteroarylazo compounds related to those studied. (C) 2000 Elsevier Science Ltd. All rights reserved.
