Identification of 2-amino-5-(thioaryl)thiazoles as inhibitors of nerve growth factor receptor TrkA
摘要:
2-Amino-5-(thioaryl)thiazoles are potent inhibitors of TrkA (e.g., 20h, TrkA IC50 = 0.6 nM) that show anti-proliferative effect in cellular assays. A proposed inhibitor binding mode to TrkA active site is consistent with key SAR observations. (c) 2007 Elsevier Ltd. All rights reserved.
正甲基和正苯甲酰基吡啶基硫脲的氧化环化。新型噻唑并[4,5- b ]和[5,4- b ]吡啶衍生物的制备
摘要:
由相应的氨基吡啶-吡啶制备的N-甲基和N-苯甲酰基吡啶基硫脲的环化已经使用各种条件实现。用溴在乙酸或铁氰化钾中的环化反应在吡啶环的氮上进行,得到吡啶鎓盐或1,2,4-噻二唑并[2,3- a ]吡啶亚砜体系。另一方面,在N-甲基吡咯烷酮(NMP)中用甲醇钠处理硫脲导致导致噻唑并[4,5- b ]和[5,4- b ]吡啶的形成,这是生物学评估中令人关注的目标。

This work describes the first successful synthesis of five pyridinium N-benzoylguanidines. These new pyridinium ylides were prepared in moderate to good yields through the guanylation reaction of N-iminopyridinium ylide with N-benzoylthioureas, using both bismuth nitrate and mercury chloride as inorganic thiophiles. X-ray analysis of one pyridinium N-benzoylguanidine was investigated and the E configuration

The antimicrobial activity of six N-phenyl- and fourteen N-benzoylthiourea derivatives were evaluated from their Minimal Inhibitory Concentration (MIC) values using the microdilution procedure against ten microorganisms. Most of the compounds exhibited selective activity against fungi and Gram-positive bacteria, which were very effectively inhibited by some of the tested thioureas. Additionally, SAR considerations and four novel X-ray diffraction structures of N-benzoylthioureas are included.
