responsible for Chagas disease. We selected compound 1 for leadoptimization, aiming to improve in parallel its anti-T. cruzi activity (IC50 = 0.63 μM) and its human metabolic stability (human clearance = 9.57 mL/min/g). A total of 39 analogues of 1 were synthesized and tested in vitro. We established a multiparametric structure–activity relationship, allowing optimization of antiparasite activity, physicochemical
酰基氨基苯并噻唑命中被确定为克氏锥虫复制的潜在抑制剂,锥虫是负责恰加斯病的寄生虫。我们选择化合物1进行铅优化,旨在同时提高其抗克鲁氏锥虫活性(IC 50 = 0.63μM)和其人类代谢稳定性(人类清除率= 9.57 mL / min / g)。总共合成了39种1的类似物,并在体外进行了测试。我们建立了多参数结构与活性的关系,从而可以优化抗寄生虫活性,理化参数和ADME特性。我们将化合物50鉴定为具有改进的体外抗T. cruzi活性的高级铅(IC50 = 0.079μM)和增强的代谢稳定性(人类清除率= 0.41 mL / min / g)和口服途径。在耐受性评估后,有50种药物显示出有希望的体内功效。

three-step synthesis towards 3-amino-1,4-benzodiazepin-2-one derivatives is presented. The versatile Ugi-4-component reaction (Ugi-4CR) and Boc deprotection is followed by a ligand-free Ullmann condensation. This protocol allows the rapid construction of a diverse array of substituted 1,5-benzodiazepinones. Since Ugi-based products are typically limited by their ‘inert’ C-terminal amides, the use of a convertible

Compounds derived from indole, notably useful in therapeutics, selected from:
i) the compounds of formula:
and
ii) the pharmaceutically acceptable salts of the compounds of formula (I);
in which R1, R2, R3, R4, R5, R6, R8, R9 and Cy have defined meanings, and the use of such compounds in pharmaceuticals for the treatment of neurodegenerative diseases, particularly Parkinson's disease.
An efficient synthesis of N-acetyl-2-substituted indole derivatives via direct intramolecular hydroamination of N-acetyl-2-alkynylaniline derivatives was developed. The reaction could be applied to a wide range of substrates employing only 1–2 mol% of PtCl4 as the catalyst to furnish the desired indole products in moderate to excellent yields. The current protocol is efficient, reliable and scalable
