Discovery of Indoline-2-carboxamide Derivatives as a New Class of Brain-Penetrant Inhibitors of Trypanosoma brucei
摘要:
There is an urgent need for new, brain penetrant small molecules that target the central nervous system second stage of human African trypanosomiasis (HAT). We report that a series of novel indoline-2carboxamides have been identified as inhibitors of Trypanosoma brucei from screening of a focused protease library against Trypanosoma brucei brucei in culture. We describe the optimization and characterization of this series. Potent antiproliferative activity was observed. The series demonstrated excellent pharmacokinetic properties, full cures in a stage 1 mouse model of HAT, and a partial cure in a stage 2 mouse model of HAT. Lack of tolerability prevented delivery of a fully curative regimen in the stage 2 mouse model and thus further progress of this series.

A novel compound of the formula
wherein Ar represents a tetracyclic fused heterocyclic group which may be substituted; R¹ represents H or a hydrocarbon group which may be substituted; Y represents an amino or nitrogen-containing saturated heterocyclic group which may be substituted, its salt, inhibiting excellent cholinesterase inhibitory activity and monoamine uptake inhibitory activity, thus being useful as therapeutic and/or prophylactic medicaments of senile dementia.
一种新颖的式化合物
其中 Ar 代表可被取代的四环融合杂环基团;R¹ 代表 H 或可被取代的烃基团;Y 代表可被取代的氨基或含氮饱和杂环基团,其盐具有优异的胆碱酯酶抑制活性和单胺摄取抑制活性,因此可用作老年痴呆症的治疗和/或预防药物。
