Development of isoniazid–NAD truncated adducts embedding a lipophilic fragment as potential bi-substrate InhA inhibitors and antimycobacterial agents
摘要:
Isoniazid-NAD truncated adducts embedding a lipophilic fragment were designed, synthesized and evaluated as inhibitors of the enoyl-acyl carrier protein (ACP) reductase (InhA) of Mycobacterium tuberculosis and as antimycobacterial agents. These compounds, planned as bi-substrate inhibitors and inspired from the active metabolite of isoniazid, combine both the nicotinamide moiety of the cofactor NAD and a lipophilic hydrocarbon chain mimic of the InhA substrate. The lipophilic fragment was introduced using either Suzuki-Miyaura cross-coupling or a classical nucleophilic substitution reaction. Several compounds developed in this work were indeed able to inhibit the InhA activity and showed promising antimycobacterial activities. However a direct correlation between the expressed activity and the bi-substrate mode of action could not yet be unambiguously demonstrated (C) 2010 Elsevier Masson SAS. All rights reserved.

The invention relates to bi-substrate inhibitor molecules associating (i) a pyridine, pyridinium or dihydropyridine-type structure allied to active metabolites of isoniazide, or related structures, and (ii) a hydrophobic substituent. The invention also relates to the method for producing said molecules, to the pharmaceutical compositions containing said molecules, and to the use thereof as inhibitors of enoyl reductase for the preparation of a medicament, especially an anti-infectious medicament for the treatment of tuberculosis.
