以水为反应介质,采用环境友好的方法合成了由2-(苄基磺酰基)苯并噻唑衍生的新型抗真菌农药。这些化合物是通过一锅法,两步合成法制备的,从2-巯基苯并噻唑和苄基卤化物开始。针对一组植物病原性真菌测试了潜在的杀菌剂,其中许多杀菌剂与未氧化的类似物和市售抗真菌药Captan相比有显着改善。新的衍生物2-((2-氯苄基)磺酰基)苯并[ d ]噻唑(4f)和2-((4-甲基苄基)磺酰基)苯并[ d ]噻唑(4k)表现出显着的性能,能够抑制生长两个抗性霉菌(烟曲霉)和曲霉菌)。无论4F和4K可以被归类为广谱杀菌剂,正在成为这些模具,这在食品生产的负面影响的控制可能的候选人。
通过环保方法合成了一系列苄基取代的硫代苯并唑,以寻找新的抗真菌农药。使用KOH,苄基卤化物和水从2-巯基苯并恶唑开始制备化合物,这是一种简单而生态的方法。测试了针对一组植物致病真菌的新型抗真菌药。两种化合物对灰霉病菌,尖孢镰刀菌和曲霉属菌显示出有趣的活性:2-((4-(三氟甲基)苄基)硫代)苯并[ d ]噻唑,3ac和2-((4-甲基苄基)硫代)苯并[ d ]噻唑,3al。因此,3ac和3al可以被认为是广谱抗真菌药。此外,与之相比,两种新化合物2-((4-碘苄基)硫代)苯并[ d ]噻唑和3ba 2-(苄硫基)苯并[ d ]恶唑和3ba具有更好的抑制灰葡萄孢和尖孢镰刀菌的作用。商用杀菌剂Captan。因此,可以将3aj和3ba视为减谱抗真菌剂。

The synthesis of a number of benzylphenylsulphides, substituted in the α-position of the benzyl moiety, is described and their toxicities to the eggs and young mites of the glasshouseredspider (Tetranychus telarius L.) are tabulated.
exhibited significant activity against both sensitive and resistant strains of M. tuberculosis and also against non-tuberculous mycobacteria. To facilitate drug design of benzoxazole as potentialantituberculosisagent, we have explored the quantitative structure–activity relationship (QSAR). We demonstrated that lower lipophilicity has significant contribution to activity. Dinitrobenzylsulfanyl derivative

were designed and synthesised as Pseudomonas aeruginosa (P. aeruginosa) quorumsensing inhibitors in this paper. We experimentally demonstrated that 6b significantly inhibited the formation of P. aeruginosa PAO1 biofilm without affecting the growth. Further mechanistic studies showed that 6b affected the luminescence of quorumsensing reported strain PAO1-lasB-gfp and the production of P. aeruginosa PAO1
A transition-metal-free protocol for the one-pot synthesis of 2-benzyl/2-allyl-substituted thiobenzoazoles in water was developed. The cyclization of 2-aminothiophenols, 2-aminophenols, and 1,2-phenylenediamines with tetramethylthiuram disulfide (TMTD) gave mercapto benzoheterocycles, and the subsequent C-S coupling with benzyl or allyl halides furnished the desired products in good to excellent yields. This method features transition-metal-free conditions with water as a solvent, an easy performance, mild reaction conditions, a wide substrate scope, and good to excellent yields, thus paving an efficient and useful way to establish a library of potentially active drug molecules.

New antifungal agrochemicals, derived from 2-(benzylsulfonyl)benzothiazole were synthesized by an environmentally friendly method, using water as reaction medium. These compounds were prepared by a one-pot, two-step synthesis, starting from 2-mercaptobenzothiazole and benzyl halides. The potential fungicides were tested against a panel of phytopathogenic fungi, with many of them showing a significant
