Usage

Uses

Used in Pharmaceutical Industry:
7-Methoxy-1,5-naphthyridin-2(1H)-one is used as a key intermediate for the synthesis of heterocyclic compounds with antibacterial properties, such as N-ethylquinolones and N-ethylazaquinolones. These compounds are valuable in the development of new antibiotics to combat bacterial infections.
Used in Antimicrobial Applications:
7-Methoxy-1,5-naphthyridin-2(1H)-one is used as a precursor in the preparation of compounds that inhibit type II topoisomerase inhibitors (NBTIs) in Pseudomonas aeruginosa. This makes it a potential candidate for the development of new treatments against drug-resistant bacterial strains, particularly those caused by Pseudomonas aeruginosa.

Mycobacterium tuberculosis gyrase inhibitors as a new class of antitubercular drugs

One way to speed up the TB drug discovery process is to search for antitubercular activity among compound series that already possess some of the key properties needed in anti-infective drug discovery, such as whole-cell activity and oral absorption. Here, we present MGIs, a new series of Mycobacterium tuberculosis gyrase inhibitors, which stem from the long-term efforts GSK has dedicated to the discovery and development of novel bacterial topoisomerase inhibitors (NBTIs). The compounds identified were found to be devoid of fluoroquinolone (FQ) cross-resistance and seem to operate through a mechanism similar to that of the previously described NBTI GSK antibacterial drug candidate. The remarkable in vitro and in vivo antitubercular profiles showed by the hits has prompted us to further advance the MGI project to full lead optimization.
