Compositions that modulate the activity of signal transducer and activator of transcription-3 (STAT3) activity as well as their methods of use, such as treatment and imaging are provided. Compositions contain small molecules such as substituted pyrazoles and are useful in treatment of diseases related to the activity of STAT3 including, for example, cancer and other diseases.

extensively studied. Meanwhile, two research groups have described the putative MOR–CCR5 heterodimers in their independent studies. The purpose of this paper is to report the design and synthesis of a bivalent ligand to explore the biological and pharmacological process of the putative MOR–CCR5 dimerization phenomenon. The developed bivalent ligand thus contains two distinct pharmacophores linked through
二价配体方法不仅用于研究 G 蛋白偶联受体二聚化和/或寡聚化的潜在机制,而且还通过靶向该过程来增强配体亲和力和/或选择性以潜在治疗各种疾病。物质滥用和成瘾使人类免疫缺陷病毒 (HIV) 感染的预防和治疗变得更加困难处理. 吗啡是一种 μ 阿片受体 (MOR) 激动剂,可以通过上调趋化因子受体 CCR5 的表达来加速 HIV 感染,趋化因子受体 CCR5 是一种众所周知的 HIV 侵入宿主细胞的共同受体,这已被广泛研究。同时,两个研究小组在他们的独立研究中描述了推定的 MOR-CCR5 异二聚体。本文的目的是报告二价配体的设计和合成,以探索推定的 MOR-CCR5 二聚化现象的生物学和药理学过程。因此,开发的二价配体包含通过间隔物连接的两个不同的药效团;理想情况下,其中一个将与 MOR 交互,另一个与 CCR5 交互。选择纳曲酮和马拉维罗作为药效团来产生这种二价探针。制备这种二价配体的整个反应路线是收敛和高效的,涉及

Crystal structures of ligand-bound G-protein-coupled receptors provide tangible templates for rationally designing molecular probes. Herein, we report the structure-based design, chemical synthesis, and biological investigations of bivalent ligands targeting putative mu opioid receptor C–C motif chemokine ligand 5 (MOR-CCR5) heterodimers. The bivalent ligand VZMC013 possessed nanomolar level binding
配体结合的 G 蛋白偶联受体的晶体结构为合理设计分子探针提供了有形的模板。在此,我们报告了针对假定的 mu 阿片受体 C-C 基序趋化因子配体 5 (MOR-CCR5) 异二聚体的二价配体的基于结构的设计、化学合成和生物学研究。二价配体VZMC013对 MOR 和 CCR5 均具有纳摩尔水平的结合亲和力,抑制 CCL5 刺激的钙动员,并比先前报道的二价配体显着提高抗 HIV-1 BaL活性。VZMC013比单独表达CCR5的细胞更大程度地抑制共表达CCR5和MOR的TZM-bl细胞中的病毒感染。此外,VZMC013以浓度依赖性方式阻断人类免疫缺陷病毒 (HIV)-1 进入外周血单核细胞 (PBMC) 细胞,并且在植物血凝素刺激的 PBMC 细胞中比不存在时更有效地抑制阿片类药物加速的 HIV-1 进入。阿片类药物。构建了VZMC013与 MOR-CCR5 异二聚体复合物结合的三维分子模型,
