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.

3,5-[5-Arylisoxazol-3-yl(4,5-dichloroisothiazol-3-yl)]-substituted 1,2,4-and 1,3,4-oxadiazoles: synthesis, palladium complexes, and catalysis of Suzuki reactions in aqueous media

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. The bimetallic reusable Pd/Fe catalyst obtained from palladium polyazole complex retained high catalytic activity after five uses.

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.

Thiazole and Isothiazole Ring-Containing Compounds in Crop Protection

Organic compounds containing five-membered aromatic heterocyclic rings play an important role in life science. Among them thiazole and isothiazole heterocycles are present in many pharmaceutical drugs and crop protection compounds and have sparked over past years an enormous interest on these scaffolds. In agrochemicals these moieties are found in 11 commercial products as well as in two development compounds. A thiazole moiety is present in seven currently marketed agrochemicals, namely the insecticides thiamethoxam and clothianidin, the fungicides thiabendazole, thifluzamide, ethaboxam, and oxathiapiprolin, and the nematicide fluensulfone, as well as in the development compound dicloromezotiaz. One compound, the fungicide isotianil, contains an isothiazole ring and three compounds a benzothiazole ring, namely the fungicide benthiavalicarb and the herbicides methabenzthiazuron and mefenacet. A benzisothiazole ring is not yet present in any commercial product, however, is found in the former nematicide development compound benclothiaz. Interestingly thiazole and isothiazole heterocycles are much less frequently found in agrochemicals than pyridine and pyrazole despite their bioisosteric relationship, which may indicate that these heterocycles have still not been explored to their full scope in crop protection lead discovery and optimization. Detailed information on the discovery, synthesis, and the structure-activity relationships of thiazole-and isothiazole-containing agrochemicals is provided in this review.

Design and synthesis of selective CDK8/19 dual inhibitors: Discovery of 4,5-dihydrothieno[3 ‘,4 ‘:3,4]benzo[1,2-d]isothiazole derivatives

To develop a novel series of CDK8/19 dual inhibitors, we employed structure-based drug design using docking models based on a library compound, 4,5-dihydroimidazolo[3′,4′:3,4]benzo[1,2-c]isothiazole 16 bound to CDK8. We designed various [5,6,5]-fused tricyclic scaffolds bearing a carboxamide group to maintain predicted interactions with the backbone C=O and NH of Ala100 in the CDK8 kinase hinge region. We found that 4,5-dihydrothieno[3′,4’:3,4]benzo[1,2-d]isothiazole derivative 29a showed particularly potent enzymatic inhibitory activity in both CDK8/19 (CDK8 IC50: 0.76 nM, CDK19 IC50: 1.7 nM). To improve the physicochemical properties and kinase selectivity of this compound, we introduced a substituted 3-pyridyloxy group into the scaffold 8-position. The resulting optimized compound 52h showed excellent in vitro potency (CDK8 IC50: 0.46 nM, CDK19 IC50: 0.99 nM), physicochemical properties, and kinase selectivity (only 5 kinases showed <35% unbound fraction at 300 nM. CDK19: 4.6%, CDK8: 8.3%, HASPIN: 23%, DYRKIB: 27%, HIP1: 32%). Based on a docking model of 52h bound to CDK8, we could explain the highly specific kinase activity profile found for this compound, based on the interaction of the pyridyl group of 52h interacting with Metl 74 of the CDK8 DMG activation loop. In vitro pharmacological evaluation of 52h revealed potent suppression of phosphorylated STAT1 in various cancer cells. The high oral bioavailability found for this compound enabled in vivo studies, in which we demonstrated a mechanism-based in vivo PD effect as well as tumor growth suppression in an RPMI8226 human hematopoietic and lymphoid xenograft model in mouse [TIC: 1% (2.5 mg/kg, qd)].
