Plasmodium falciparum. Structure–activityrelationshipstudies led to the identification of highly promising analogues, the most potent of which had IC50s in the nanomolar range against both strains. The compounds further demonstrated good in vitro microsomal metabolic stability while those subjected to in vivo pharmacokinetic studies had desirable pharmacokinetic profiles. In vivo antimalarial efficacy in Plasmodium
Discovery of novel series of 2-substituted benzo[d]oxazol-5-amine derivatives as multi-target directed ligands for the treatment of Alzheimer's disease
Alzheimer'sdisease (AD) is associated with multifactorial neuropathological conditions, which include cholinergic deficit, amyloid-beta plaques formation, loss of neuronal plasticity and neuronal death. Treating such multifactorial conditions with a single target directed approach is considered to be inadequate. Accordingly, multi-targetdirectedligand (MTDL) strategy has been evolved as an auspicious
阿尔茨海默氏病(AD)与多因素神经病理学状况相关,包括胆碱能缺乏,淀粉样β斑块形成,神经元可塑性丧失和神经元死亡。用单一靶标定向方法治疗这种多因素疾病被认为是不充分的。因此,已经发展了多靶标定向配体(MTDL)策略作为用于治疗AD的吉祥方法。有鉴于此,采用脚手架跳跃式MTDLs策略设计了2-取代的苯并[d]恶唑-5-胺衍生物(29-39; 86-107)库,并通过各种体外和体外方法进行了合成和评估。体内生物学研究。最佳化合物92对AChE(IC50 = 0.052±0.010μM),BuChE(IC50 = 1.085±0.035μM),和显着的淀粉样β聚集(20μM)抑制作用。该化合物在PAMPA分析中具有更好的血脑屏障通透性(Pe = 10.80±0.055×10-6 cm s-1),并在SH-SY5Y神经母细胞瘤细胞系中具有神经保护特性(40μM)。此外,在Y-迷宫测试(东pol碱诱
