The present invention relates generally to novel substituted oxindole compounds and compositions. Such compounds and compositions have utility as pharmacological agents in treating diseases or conditions alleviated by the inhibition or antagonism of protein kinase activated signalling pathways. In particular, the present invention relates to a series of substituted oxindole compounds, which exhibit protein tyrosine kinase and protein serine/threonine kinase inhibition, and which are useful in inhibiting tumor growth via inhibition of such kinases as well as protecting a patient undergoing chemotherapy from chemotherapy induced alopecia.

Fluorescent tryptophan analogs, like azatryptophan, offer an advantage for exploring protein and peptidestructure and dynamics. The chromophoric moieties, azaindole, of the azatryptophan analogs are investigated for their potential as fluorescentprobes. The photophysical properties of 4-azaindole (4AI) and 5-azaindole (5AI) and their tautomers are characterized through computational and experimental
荧光色氨酸类似物,例如氮杂色氨酸,为探索蛋白质和肽的结构及动力学提供了优势。研究了氮杂色氨酸类似物的发色部分氮杂吲哚作为荧光探针的潜力。通过计算和实验方法表征了4-氮杂吲哚(4AI)和5-氮杂吲哚(5AI)及其互变异构体的光物理性质。4AI和5AI均在1 M NaOH存在下经历激发态互变异构。4AI和5AI的质子化形式分别具有415和410 nm的荧光发射,而4AI和5AI的互变异构体分别具有480和450 nm的荧光发射。气相计算(B3LYP / 6-31 + G **)表明,N1H氮杂吲哚互变异构体在基态下的能量降低了12.5 kcal mol(-1),而N(n)H氮杂吲哚互变异构体在激发态时的能量低至18.1 kcal mol(-1)。使用等密度极化连续谱模型(IPCM)计算了互变异构体能量差的溶剂效应。溶剂的极性有助于将处于基态的互变异构体之间的能量差减少多达5.8 kcal mo
