NOVEL ANTI-INFECTIOUS DERIVATIVES, METHOD FOR THE PRODUCTION THEREOF, PHARMACEUTICAL COMPOSITIONS CONTAINING SAME AND USES OF SAID DERIVATIVES IN TREATMENT
New cyclopenta-fused polycyclic aromatic hydrocarbons (CP-PAHs) based on tetracene have been prepared by a palladium-catalyzed cyclopentannulation reaction. The new compounds have low-energy lowest unoccupied molecular orbitals (LUMOs) and relatively small band gaps. The photooxidative stability was intermediate to previously prepared CP-PAHs based on anthracene and pentacene as found in traditional

Chemical synthesis, biological evaluation and structure–activity relationship analysis of azaisoindolinones, a novel class of direct enoyl-ACP reductase inhibitors as potential antimycobacterial agents
The synthesis and biological evaluation of azaisoindolinone compounds embedding a lipophilic chain on the framework were performed. These compounds were designed as InhA inhibitors and as anti-Mycobacterium tuberculosis agents. Structure-activity relationships concerning the length and the location of the lipophilic chain around the azaisoindolinone framework, the suppression of the phenyl group, the bioisosteric substitution of ether link and alkylating of the tertiary hydroxyl and the hemiamidal nitrogen were also investigated, revealing insightful information and thereby enabling further diversification of the azaisoindolinone scaffold for new antitubercular agents.

Development of isoniazid–NAD truncated adducts embedding a lipophilic fragment as potential bi-substrate InhA inhibitors and antimycobacterial agents
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.

Contorted hexabenzocoronenes (HBCs) have been synthesized in an expedited manner utilizing a double Barton-Kellogg olefination reaction and a subsequent Scholl cyclization. The scope of both transformations was investigated using a series of pentacene quinones and double olefin precursors. The utility,of these reactions to help create functionalized and oligomeric HBCs in a rapid manner is demonstrated.
