proved to be unstable and reacted readily with glutathione when exposed to light and oxygen. Reactivity was reduced by the introduction of a nitrogen atom alpha to the indolizine nitrogen. The pyrrolopyridazine core obtained proved to be inert to the action of light and oxygen. The synthesis route followed the one used for the indolizine compounds, and the potency and ADMET profile proved to be similar
从HTS战役中鉴定出一种新型的吲哚利嗪类化合物为TRPV1拮抗剂。然而,事实证明,这种吲哚利嗪类化合物不稳定并在暴露于光和氧气时容易与谷胱甘肽反应。通过向吲哚嗪氮中引入氮原子α,降低了反应性。所获得的吡咯并哒嗪核心被证明对光和氧气的作用是惰性的。合成路线遵循用于吲哚嗪化合物的路线,并且效力和ADMET曲线被证明是相似的。
