evaluated by electron capture (EC) and electronimpact (EI) modes of massspectrometry (MS). By EC-MS, 1 nearly gave a single ion (as desired), whereas 2 gave many ions. This behavior was completely reversed in EI-MS. To account for certain ion fragments in the EC mass spectrum of 2, an anion radical McLafferty-type rearrangement and loss of a carbene neutral were postulated. Electronimpact of 1 gave
为了找到适合用作电泳释放标签分子标记的新型酮电泳的目的,制备了五氟苯氧基丙酮(1)和五氟苄氧基丙酮(2)。两种酮均通过质谱(MS)的电子捕获(EC)和电子碰撞(EI)模式进行评估。通过EC-MS,1几乎给出了一个离子(根据需要),而2给出了许多离子。在EI-MS中,这种行为被完全颠倒了。为了说明EC质谱图2中的某些离子碎片,假定了阴离子自由基McLafferty型重排和卡宾中性的损失。1的电子冲击在m / z 117(C5F3 +)处产生大量离子,这被认为是二炔阳离子。

The present disclosure provides thiazolyl-containing compounds of Formula (I), (II), or (III). The compounds described herein may be able to inhibit protein kinases (e.g., Src family kinases (e.g., hemopoietic cell kinase (HCK)), Bruton's tyrosine kinase (BTK)) and may be useful in treating and/or preventing proliferative diseases (e.g., myelodysplasia, leukemia, lymphoma (e.g., Waldenström's macroglobulinemia)) and in inducing apoptosis in a cell (e.g., malignant blood cell). Also provided in the present disclosure are pharmaceutical compositions, kits, methods, and uses including or using a compound described herein.
