A number of hydrazines, hydrazides, and related compounds have been condensed with isatin and substituted isatins. The anticonvulsant activity of these compounds is reported.
许多肼,酰肼和相关化合物已与Isatin和取代的Isatin缩合。报道了这些化合物的抗惊厥活性。

intercalators. In contrast, Isatin binds with ctDNA via groove mode (Kb[Isatin–ctDNA] = 7.32 × 104 L mol−1) without any significant enhancement in ctDNA viscosity. The fluorescence quenching of Isatin by ctDNA was observed as static. CD spectra indicated that Isatin effectively absorbs into grooves of ctDNA, leading to transition from B to C form. Thermodynamic parameters like enthalpy changes (∆H < 0) and entropy
研究了Isatin及其衍生物Isatin-3-isonicotinylhydrazone(IINH)和Isatin-β-thiosemicarbazone(IBT)与小牛胸腺DNA(ctDNA)的相互作用,以利用UV-Vis /荧光/圆二色性描述药物理化性质。 (CD)光谱,粘度测量和多元化学计量学。IINH和IBT分子插入DNA的碱基对之间,UV吸收的变色,CD阳性谱带的增加,比粘度的急剧增加以及IINH和IBT与ctDNA形成的亚甲基蓝和中性红染料的置换。分子。观察到的固有结合常数(K b [IBT–ctDNA] = 1.03×10 5和K b[IINH–ctDNA] = 1.09×10 5 L mol -1)与其他嵌入剂大致相当。相反,Isatin通过凹槽模式(K b [Isatin–ctDNA] = 7.32×10 4 L mol -1)与ctDNA结合,而ctDNA粘度

Several substituted isatin 3-acylhydrazones (e.g. 1a–k, n, p, t) have been synthesized. Under acetylating conditions they were transformed into selectively acetylated derivatives (e.g., 1l, n, o, q–s) and into the novel, title spiroheterocycles (2a–i). Some side reactions occurring under various acetylating conditions are also discussed.

glucose-lowering effect of incretins. In the current research, synthesis, characterization, docking, and biologicalevaluation of fourteen Schiff’s bases 5a–f and 9a–h were carried out. Compound 9f revealed the best in vitro anti-DPP-IV activity of 35.7% inhibition at a concentration of 100 μM. Compounds 9c and 9f with the highest in vitro DPP-IV inhibition were subjected to the in vivo glucose-lowering test
