Natural isoflavone biochanin A as a template for the design of new and potent 3-phenylquinolone efflux inhibitors against Mycobacterium avium

Mycobacterium avium is a difficult-to-treat pathogen able to quickly develop drug resistance. Like for other microbial species, overexpression of efflux pumps is one of the main mechanisms in developing multidrug resistance. Although the use of efflux pumps inhibitors (EPIs) represents a promising strategy to reverse resistance, to date few M. avium EPIs are known. Recently, the […]

Probing the aurone scaffold against Plasmodium falciparum: design, synthesis and antimalarial activity

A library comprising 44 diversely substituted aurones derivatives was synthesized by straightforward aldol condensation reactions of benzofuranones and the appropriately substituted benzaldehydes. Microwave enhanced synthesis using palladium catalyzed protocols was introduced as a powerful strategy for extending the chemical space around the aurone scaffold.

Design, synthesis and biological evaluation of novel isoniazid derivatives with potent antitubercular activity

The disturbing emergence of multidrug-resistant strains of Mycobacterium tuberculosis(Mtb) has been driving the scientific community to urgently search for new and efficient antitubercular drugs. Despite the various drugs currently under evaluation, isoniazid is still the key and most effective component in all multi-therapeutic regimens recommended by the WHO. This paper describes the QSAR-oriented design, synthesis and in vitro antitubercular activity of several potent isoniazid derivatives (isonicotinoyl hydrazones and isonicotinoyl hydrazides) against H37Rv and two resistant Mtb strains.
