  New hydrazides derivatives of isoniazid against Mycobacterium tuberculosis: Higher potency and lower hepatocytotoxicity

  摘要：

  Tuberculosis (TB) is one of the leading causes of death worldwide. The emergence of multi-drug resistant strains of Mycobacterium tuberculosis (Mtb) and TB-HIV co-infection are major public health challenges. The anti-TB drugs of first choice were developed more than 4 decades ago and present several adverse effects, making the treatment of TB even more complicated and the development of new chemotherapeutics for this disease imperative. In this work, we synthesized two series of new acylhydrazides and evaluated their activity against different strains of Mtb. Derivatives of isoniazid (INH) showed important anti-Mtb activity, some being more potent than all anti-TB drugs of first choice. Moreover, three compounds proved to be more potent than INH against resistant Mtb. The Ames test showed favorable results for two of these substances compared to INH, one of which presented expressly lower toxicity to HepG2 cells than that of INH. This result shows that this compound has the potential to overcome one of the main adverse effects of this drug. (C) 2018 Elsevier Masson SAS. All rights reserved.

  新型氯喹和伯氨喹杂种的抗疟和抗炎活性：靶向阻断疟原虫传播

  摘要：

  疟疾是一种不仅需要抗疟原虫而且还需要减少感染症状（如发烧和发炎）的新药。从氯喹（CQ）和伯氨喹（PQ）设计了一系列21种杂化化合物，这些化合物与苯乙酸抗炎药中存在的药效基团相连。这些化合物被设计为具有双重活性：即，能够杀死疟原虫并且仍然对由疟疾感染引起的炎症过程起作用。用九种不同的生物学方法测定化合物。羰基化的CQ衍生物6（n = 3; R 1  = Cl）在体外比CQ更有效，而8（n = 4; R 1 ＝ H）在第7天将伯氏疟原虫寄生虫病降低至37％。羰基化的PQ衍生物17（R ＝ Br）的效力略低于PQ。所述宝石二氟PQ衍生物20（R = Cl）的表现出的蚊子的疟疾孢子生殖周期的高传输封锁。化合物6和20剂量依赖性地减少LPS刺激的J774A.1巨噬细胞产生的一氧化氮（NO）的产生并抑制TNFα的产生。我们的结果表明，在规划用作阻止恶性疟原虫和间日疟原虫引起的疟疾的传播阻断药物的新化学实体方面，可行且有趣的方法

  evaluation of new compounds using the K562 cell line, which constitutively expresses the active BCR-ABL enzyme. Three new series of imatinib derivatives have been planned from the imatinib, and all have a phenylaminopyrimidine group as the main pharmacophore. Sunitinib was used as a structural prototype to planning the series 1 (8a–e) of hybrids between sunitinib and imatinib. Series 2 and 3 are 2

  Background: Statins present a plethora of pleiotropic effects including anti-inflammatory and antimicrobial responses. A,α-difluorophenylacetamides, analogs of diclofenac, are potent pre-clinical anti-inflammatory non-steroidal drugs. Molecular hybridization based on the combination of pharmacophoric moieties has emerged as a strategy for the development of new candidates aiming to obtain multitarget ligands
