摘要:本研究证明了工业相关有机酸(即甲磺酸,三氟甲磺酸和三氟乙酸)的按需原位制备.发现溴酸钠和溴酸钾选择性地氧化一系列铵盐 Nh 4 X,其中 X = Oms,Otf 或 Otfac,具有特征时钟反应行为.在 150 oc 下延长诱导时间后,氧化还原系统经历快速酸形成,被确定为需要按需放置酸的高温油田化学应用的潜在候选者.尽管从 Nh 4 X 盐形成酸的反应动力学(其中 X = Cl,Br,F 或 So 4 2-)遵循 Ap K A趋势,有机酸的形成速度要慢得多,并偏离这一趋势.此外,我们证明酸的形成速率可以通过添加碱金属盐来调节,从 Libr 观测到的效果最强.光谱研究表明溴酸锂离子对的形成会减缓或完全抑制 Nh 4 +的氧化.此外,Br-的存在改变了反应路径,消除了时钟行为并为 Li +创建了一条强烈抑制氧化还原反应的途径.从这些研究中,确定了一种在储层条件下减缓铵氧化以充分延迟酸形成直到前体置于感兴趣区域的方法.

摘要:A process and intermediate useful for forming a 1H-Pyrazolo[1,5-b][1,2,4]triazole compounds comprise the step of reacting a 1,5-diaminopyrazole bearing a substituent, bonded to one and only one of the amine nitrogens by an acyl or thioacyl group, with a dehydrating agent in the presence of an aprotic solvent.

摘要:The present invention provides a series of cyclin-dependent protein kinases (Cdks) inhibitors, Scutellaria flavonoid organic amine derivatives, synthesis and use thereof. The preparation method is as follows: taking Baicalein (or Wogonin) from Scutellaria baicalensis as lead compound, mixting it with formaldehyde solution and organic amine compounds based on the molar ratio of 1:1-1.2:1-1.2, adding methanol of duplicate weight than baicalein and reacting at 50-70° C., filtering the sediment and washing and then drying so as to get the product with a content of not less than 97% (weight). Similar to Flavopiridol and P276-00, the activity of baicalein organic amine derivatives inhibiting Cdks has an increase of 50 times compared with that of Baicalin. It can selectively induce apoptosis of the proliferative phase cancer cells, which has scarcely any influence to the normal structure, and it belongs to anticancer drugs of cell cycle inhibitor kind. The product has a rich source of raw materials and has simple process, high purity, low cost, clear metabolic mechanism, high efficiency and low toxicity, which can be made into oral preparations or injections together with acid salts and is expected to become high efficient and low toxicity anti-cancer and AIDS drugs.

摘要:The present invention generally relates to novel synthetic methods, systems, kits, salts, and precursors useful in medical imaging. In some embodiments, the present invention provides compositions comprising an imaging agent precursor, which may be formed using the synthetic methods described herein. An imaging agent may be converted to an imaging agent using the methods described herein. In some cases, the imaging agent is enriched in 18 F. In some cases, an imaging agent including salt forms (e.g., ascorbate salt) may be used to image an area of interest in a subject, including, but not limited to, the heart, cardiovascular system, cardiac vessels, brain, and other organs.
