Design, synthesis, fungicidal activities and structure–activity relationship studies of (?)-borneol derivatives containing 2-aryl-thiazole scaffold

A series of (-)-borneol derivatives containing 2-aryl-thiazole scaffold were designed, synthesized, and characterized by 1H NMR, 13C NMR, and HRMS. The fungicidal activities of these novel compounds against Fusarium oxysporum, Magnaporthe grisea, Botrytis cinerea, and Penicillium digitatum were evaluated. The results indicated that (1S,2R,4S)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl(Z)-4-oxo-4-(((2-phenylthiazol-4-yl)methyl)amino)but-2-enoate (6a) displayed potential fungicidal activities with broad spectrum. Especially, 6a exhibited an IC50 value of 48.5 mg/L against P. digitatum, which has higher fungicidal activity than commercial products hymexazol and amicarthiazol. Moreover, (1S,2R,4S)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl-4-oxo-4-(((2-phenylthiazol-4-yl)methyl)amino)butanoate (5a) possesses an IC50 value of 24.3 mg/L against B. cinerea, comparable to hymexazol and far superior to amicarthiazol. Furthermore, the superficial structure–activity relationship was discussed, which might be helpful for discovering novel fungicides.

Design, synthesis, and bioactivities of novel pyridazinone derivatives containing 2-phenylthiazole or oxazole skeletons

A series of novel pyridazinone derivatives were designed and synthesized by replacing 4-(tert-butyl)phenyl moiety of pyridaben with 2-phenylthiazole or oxazole fragments via activity substructure connecting approach. The structures of all target compounds were characterized through NMR, MS, and elemental analysis. Bioassay results exhibit that most compounds showed potent bioactivities against Aphis fabae, Tetranychus urticae, Erysiphe graminis, and/or Puccinia polysora. Among the newly synthesized compounds, 2-(tert-butyl)-4-chloro-5-(((2-phenylthiazol-4-yl)methyl)thio)pyridazin-3(2H)-one (12b) displays remarkable insecticidal activity against A fabae. Its LC50 value (2.73 mg/L) is better than that of pyridaben (5.46 mg/L), although inferior to that of imidacloprid (0.51 mg/L). In addition to its extraordinary insecticidal activity, compound 12b also exerts 96.9% fungicidal activities against P polysora at 500 mg/L in vivo, significantly superior to that of pyridaben (50.0%), while slightly lower than that of tebuconazole (100%). This article discusses the synthesis, bioassay results, and structure-activity relationship of this series of novel pyridazinone derivatives.

Design, synthesis and fungicidal activity evaluation of novel pyrimidinamine derivatives containing phenyl-thiazole/oxazole moiety

Diflumetorim is a member of pyrimidinamine fungicides that possess excellent antifungal activities. Nevertheless, as reported that the activity of diflumetorim to corn rust (Puccinia sorghi) was not ideal (EC50 = 53.26 mg/L). Herein, a series of novel pyrimidinamine derivatives containing phenyl-thiazole/oxazole moiety were designed based on our previous study and the structural characteristics of diflumetorim, synthesized and bioassayed to discover novel fungicides with excellent antifungal activities. Among these compounds, T18 gave the optimal fungicidal activity, which respectively offers control effects with EC50 values of 0.93 mg/L against P. sorghi and 1.24 mg/L against E. graminis, significantly superior to commercial fungicides diflumetorim, tebuconazole, and flusilazole. Cell cytotoxicity results suggested that compound T18 has lower toxicities than diflumetorim. Furthermore, DFT calculation indicated that the phenyl-thiazole/oxazole moiety plays an unarguable role in the improvement of activity, which will contribute to designing and developing more potent compounds in the future.

Design, synthesis, DFT study and antifungal activity of the derivatives of pyrazolecarboxamide containing thiazole or oxazole ring

Pyrazolecarboxamide fungicides are one of the most important classes of agricultural fungicides, which belong to succinodehydrogenase inhibitors (SDHIS). To discover new pyrazolecarboxamide analogues with broad spectrum and high activity, a class of new compounds of pyrazole carboxamide derivatives containing thiazole or oxazole ring were designed by scaffold hopping and bioisosterism, and 36 pyrazole carboxamide derivatives with antifungal activity were synthesized. Those compounds were evaluated against five phytopathogenic fungi, Gibberella zeae, Phytophythora capsici, Sclerotonia sclerotiorum, Erysiphe graminis and Puccinia sorghi. The results indicated that most of the compounds displayed good fungicidal activities, especially against E. graminis. Theoretical calculations were carried out at the B3LYP/6-31G (d, p) level and the full geometry optimization was carried out using the 6-31G (d, p) basis set, and the frontier orbital energy, atomic net charges, molecular docking were discussed, and the structure-activity relationships were also studied.

A series of novel 1H-pyrazole-5-carboxamide compounds containing the phenyl thiazole moiety were designed and synthesized by a facile method, and their structures were characterized by 1H NMR, mass spectrometry and elemental analysis.

Stereoselective Synthesis of β-(5-Arylthiazolyl) α-Amino Acids and Use in Neurotensin Analogues

A series of new unnatural amino acids bearing a β-arylthiazole side chain was synthesized by exploiting a diastereoselective alkylation starting from glycine tert-butyl ester Schiff base with hydroxypinanone as the chiral inducer. This strategy afforded β-arylthiazole alanines in good chemical yields and with 98 % ee. Due to their aromatic properties, these newly generated amino acids were used to prepare neurotensin (NT)[8-13] analogues by serving as replacements for the native Tyr11 residue. Incorporation of the (L)-(+)-(β-phenylthiazol-4-yl)alanine residue at NT[8-13] position 11 improved plasma stability and selectivity towards NTS1, while also preserving native receptor binding affinity and biological activity. New β-arylthiazole alanines were synthesized in good chemical yields and with 98 % ee using a diastereoselective alkylation; these alanine derivatives were then used as Tyr11 replacements in the construction of neurotensin (NT)[8-13] analogues. The new NT analogues showed improved plasma stability and selectivity towards NTS1 thus preserving the hypotensive properties of the native peptide.

Agonists for the adenosine A1 receptor with tunable residence time. a case for nonribose 4-amino-6-aryl-5-cyano-2-thiopyrimidines

We report the synthesis and evaluation of previously unreported 4-amino-6-aryl-5-cyano-2-thiopyrimidines as selective human adenosine A 1 receptor (hA1AR) agonists with tunable binding kinetics, this without affecting their nanomolar affinity for the target receptor. They show a very diverse range of kinetic profiles (from 1 min (compound 52) to 1 h (compound 43)), and their structure-affinity relationships (SAR) and structure-kinetics relationships (SKR) were established. When put in perspective with the increasing importance of binding kinetics in drug discovery, these results bring new evidence of the consequences of affinity-only driven selection of drug candidates, that is, the potential elimination of slightly less active compounds that may display preferable binding kinetics.
