Identification and optimization of a new series of anti-tubercular quinazolinones
摘要:
A high throughput phenotypic screening against Mycobacterium smegmatis led us to the discovery of a new class of bacteriostatic, highly hydrophobic antitubercular quinazolinones that potently inhibited the in vitro growth of either extracellular or intramacrophagic M. tuberculosis (Mtb), via modulation of an unidentified but yet novel target. Optimization of the initial hit compound culminated in the identification of potent but poorly soluble Mtb growth inhibitors, three of which were progressed to in vivo efficacy studies. Despite nanomolar in vitro potency and attractive PK properties, none of these compounds was convincingly potent in our in vivo mouse tuberculosis models. This lack of efficacy may be linked to the poor drug-likeness of the test molecules and/or to the properties of the target.[GRAPHICS](C) 2016 Elsevier Ltd. All rights reserved.

2-Methoxyethoxy-benzenes are obtained in an advantageous manner from the corresponding phenol compounds by reaction with 2-chloroethyl methyl ether if the process is carried out without the addition of a strong solvent at temperatures above 95° C. and under pressure. The present invention also relates to novel 2-methoxyethoxy-benzyl cyanides.
