Actions biochimiques/physiologiques

Streptonigrin (SN) is an aminoquinone antitumour antibiotic. Its antineoplastic activity requires reductive activation by Xanthine-converting enzymes. It induces apoptosis by a mechanism involving NF-κB. DNA cleavage reaction and chromosome damage by SN are influenced by the nature of the metal ion present and dependent on the production of free radicals. Its antibiotic activity is iron-activated.

Iron is essential for most bacteria to survive, but excessive iron leads to damage by the Fenton reaction. Therefore, the concentration of intracellular free iron must be strictly controlled in bacteria. Riemerella anatipestifer (R. anatipestifer), a Gram-negative bacterium, encodes the

Streptococcus pyogenes (group A streptococcus [GAS]) is a serious human pathogen with the ability to colonize mucosal surfaces such as the nasopharynx and vaginal tract, often leading to infections such as pharyngitis and vulvovaginitis. We present genome-wide transcriptome sequencing (RNASeq)

Group A streptococcus (GAS) produces millions of infections worldwide, including mild mucosal infections, postinfection sequelae, and life-threatening invasive diseases. During infection, GAS readily acquires nutritional iron from host heme and hemoproteins. Here, we identified a new heme importer, named SiaFGH

A series of N-propargylindole-2-carboxamides were found to undergo a AuCl 3-catalyzed cycloisomerization to give beta-carbolinones in high yield. The corresponding beta-chlorocarboline derivative was prepared and used for Pd(0)-catalyzed cross-coupling chemistry directed toward the synthesis of lavendamycin analogues.

Scleromyxedema is associated with a monoclonal gammopathy and other comorbidities. Its prognostic and therapeutic features are poorly documented because most reports deal with single cases or small series. We sought to describe the characteristics of patients with scleromyxedema regarding demographics
