由于抗性的发展,总是需要新的杀虫靶标。的Hex1,一个β- Ñ乙酰基d氨基己糖苷酶在识别亚洲玉米螟(亚洲玉米螟),是参与昆虫几丁质分解代谢并已证明对于杀虫剂发展的理想靶标。在这项研究中,基于结构的虚拟筛选,结构简化,和生物学评价用于显示与联苯磺酰胺骨架有很大的潜力作为化合物中Hex1抑制剂。具体而言,化合物10k、10u和10v具有K i值分别为 4.30、3.72 和 4.56 μM,因此,它们比一些报道的非糖基抑制剂更有效,例如粘液素 B 1 ( K i = 26 μM)、小檗碱 ( K i = 12 μM)、2 ( K i = 11.2 μM),和3 ( K i= 28.9 微米)。此外,抑制动力学评估表明,目标化合物在底物方面是竞争性抑制剂,并且基于毒性预测,它们中的大多数具有有效的药物特性。所得结果表明,联苯磺酰胺骨架具有化学结构简单、合成易处理、活性强、毒性低等特点,在以Hex1

Allostericmodulators of the cannabinoid CB1receptor have recently been reported as an alternative approach to modulate the CB1receptor for therapeutic benefits. In this study, we report the design and synthesis of a series of diarylureas derived from PSNCBAM-1 (2). Similar to 2, these diarylureas dose-dependently inhibited CP55,940-induced intracellular calcium mobilization and [35S]GTP-γ-S binding

The present invention provides novel diarylurea derivatives (compounds of formula (I)) and their uses. The compounds of the present invention are demonstrated to be allosteric modulators of the CB1 receptor, and therefore useful for the treatment of diseases and conditions mediated by CB1.

This article describes the design, optimisation and development of a Suzuki cross-coupling protocol mediated by an efficient palladium-encapsulated catalyst (Pd EnCat) under microwave irradiation. The methodology has been used in both batch mode for classical library preparation and in continuous-flow applications furnishing multigram quantities of material. Described is a method that uses direct focused

the first time allows the decarboxylative cross‐coupling of aryl and acyl carboxylates with aryl triflates. In contrast to aryl halides, these electrophiles give rise to non‐coordinating anions as byproducts, which do not interfere with the decarboxylation step that leads to the generation of the carbon nucleophilic cross‐coupling partner. As a result, the scope of carboxylate substrates usable in this

cyclodextrin‐supported palladium complex (DACH‐Pd‐β‐CD) catalytic system was designed and synthesized, which can efficientlycatalyze Suzuki–Miyaura cross‐couplingreactions between aryl halides and arylboronicacid in water under mild conditions. The catalyst was successfully characterized using the methods of transmission electron microscopy, energy‐dispersive X‐ray spectrometry, X‐ray diffraction, thermogravimetric
