Disclosed is a toner for electrophotography, which has good hue, good light resistance and good electrostatic charge, and is capable of providing images that are free from white spots. The toner for electrophotography exhibits a good performance. Specifically disclosed is a toner for electrophotography, which is characterized by containing at least one metal-containing compound that is represented by general formula (1). (In the formula, R1 represents an alkyl group; R2 represents a hydrogen atom, an alkoxycarbonyl group, an aryloxycarbonyl group, a sulfamoyl group, a sulfinyl group, an alkylsulfonyl group, an arylsulfonyl group, an acyl group, a halogen atom or a cyano group; and R3 represents a group that has 9 or more carbon atoms and an aromatic hydrocarbon structure.)

showed that neither the affinity nor the selectivity of the ester and lactam analogs was improved for BRD4-1 and the first bromodomain of the testis-specific bromodomain (BRDT-1). The esters retained affinity comparable to the parent compound, whereas the affinity for the amide analogs was reduced 10-fold. A representative benzyl esteranalog was found to retain high selectivity for BET bromodomains
基于先前报道的 1,4-二氢吡啶丁内酯虚拟筛选结果,制备了九种内酯开环酯和七种酰胺类似物。这些类似物旨在提供与睾丸特异性溴结构域 (ZA) 通道 ZA 环入口处的残基的相互作用,以增强对溴结构域和溴结构域额外末端 (BET) 亚家族的亲和力和选择性。 AlphaScreen 进行的化合物测试表明,对于 BRD4-1 和睾丸特异性溴结构域 (BRDT-1) 的第一个溴结构域,酯和内酰胺类似物的亲和力和选择性均未得到改善。酯类保留了与母体化合物相当的亲和力,而对酰胺类似物的亲和力却降低了 10 倍。 BROMOscan 表明,一种代表性的苄基酯类似物对 BET 溴结构域保持了高选择性。对与 BRD4-1 和 BRDT-1 复合的烯丙酯类似物的 X 射线分析表明,酯侧链位于 ZA 环附近并且暴露于溶剂。

The sodiumiodidesymporter (NIS) is responsible for the accumulation of iodide in the thyroid gland. This transport process is involved in numerous thyroid dysfunctions and is the basis for human contamination in the case of exposure to radioactive iodine species. 4‐Aryl‐3,4‐dihydropyrimidin‐2(1H)‐ones were recently discovered by high‐throughput screening as the first NIS inhibitors.
