A small library of novel 1-aroyl-3-(4-aminosulfonylphenyl)thiourea derivatives was synthesized by the reaction of sulfanilamide with substituted aroyl isothiocyanates in dry acetonitrile. The scope of the reaction was indicated by the synthesis of 1-undecanoyl-3-(4-aminosulfonylphenyl)thiourea, an acyl derivative involving alkanoyl isothiocyanate. All the compounds have been characterized by analytical

Synthesis of novel acylthioureas bearing naphthoquinone moiety as dual sensor for high-performance naked-eye colorimetric and fluorescence detection of CN− and F− ions and its application in water and food samples
4e showed a chromogenic different sensitivity response to CN− and F− against competing anions such as AcO− and H2PO4− in DMSO. Furthermore, CN− added 4e showed an increase at the emission intensity and intensive fluorimetric color change was observed in UV-light (λex. 365 nm). All sensors showed chromogenic selectivity towards CN− in aqueous solutions (in DMSO/H2O: 1:1, v/v). Interaction mechanisms
在本研究中,以高产率 (88–96%) 合成了六种带有萘醌部分的新型酰基硫脲传感器,并使用1 H/ 13 C NMR、FT-IR 和 HRMS 技术进行了表征。所有合成的传感器 ( 4a-f ) 都显示出由 CN -、F -、AcO -和 H 2 PO 4 -引起的吸光度和比色变化的变化。然而,4e在 DMSO 中对 CN -和 F -对竞争性阴离子(例如 AcO -和 H 2 PO 4 - )显示出不同的显色灵敏度响应。此外,CN-添加的4e显示发射强度增加,并且在紫外光(λex. 365 nm)中观察到强烈的荧光颜色变化。所有传感器都显示出对水溶液中CN - 的显色选择性(在 DMSO/H 2 O 中:1:1,v/v)。4e与CN -和F -阴离子之间的相互作用机制通过使用各种光谱方法如UV/Vis、荧光、1 H/ 19 F NMR和DFT计算的实验研究来研究。结果表明,CN -与4e相互作用的主要机制是氰化物与
Synthesis, anti-inflammatory activity, inverse molecular docking, and acid dissociation constants of new naphthoquinone-thiazole hybrids
compounds involve naphthoquinone and thiazole moieties in their core structures. Thereby, here we report the synthesis, characterization and anti-inflammatory activities of new naphthoquinone thiazole hybrids by reaction of naphthoquinone acyl thioureas with various α-bromoketone derivatives. The position of NO2 group in one of the phenyl rings of naphthoquinone thiazole hybrids was changed while different
