Oximino-piperidino-piperidine-based CCR5 antagonists. Part 2: synthesis, SAR and biological evaluation of symmetrical heteroaryl carboxamides
摘要:
The synthesis, SAR and biological evaluation of symmetrical amide analogues of our clinical candidate SCH 351125 are described. A series of potent and orally bioavailable CCR5 antagonists containing symmetrical 2,6-dimethyl isonicotinamides and 2, 6-dimethyl pyrimidines amides were generated with enhanced affinity for the CCR5 receptor.

Abstract Elastic anomalies in PotassiumSulphamate, (KNH 2 SO 3 ), above room temperature were detected from temperature variation of elastic constants measured by ultrasonic Pulse Echo Overlap technique. PotassiumSulphamate has been reported to be a ferroelectric and piezo electric material. The elastic constants C 11 , C 44 , C 55 and C 66 have exhibited weak anomalies around 350 K. The DC conductivity
摘要 通过超声脉冲回波重叠技术测量的弹性常数的温度变化,检测了高于室温的氨基磺酸钾(KNH 2 SO 3 )的弹性异常。据报道,氨基磺酸钾是一种铁电和压电材料。弹性常数 C 11 、C 44 、C 55 和 C 66 在 350 K 附近表现出弱异常。沿 a 、 b 和 c 轴的直流电导率测量也支持这一结论。
Synthesis and Characterization of a New Energetic Salt based on Dinitramide
The development of new ionic salt as green propellants is one of intense investigations to replace toxic N, N′‐dimethylhydrazine. A newenergeticsalt N, N′,N′′‐tri(propan‐2‐ylidene)methanetriamium dinitramide (NTAGDN) based on dinitramide was synthesized by reacting silver dinitramide with triaminoguanidinium chloride. The structure of this newenergeticsalt was confirmed by single‐crystal X‐ray
