Aryl beta-diketo acids (ADK) comprise a general class of potent HIV-1 integrase (IN) inhibitors, which can exhibit selective inhibition of strand transfer reactions in extracellular recombinant IN assays and provide potent antiviral effects in HIV-infected cells. Recent studies have shown that polycyclic aryl or aryl rings bearing aryl-containing substituents are components of potent members of this class. Reported herein is the first use of azido functionality as an aryl replacement in beta-diketo acid IN inhibitors. The ability of azido-containing inhibitors to exhibit potent inhibition of IN and antiviral protection in HIV-infected cells, renders the azide group of potential value in the further development of ADK-based IN inhibitors.

Selected sulfonic acids, their derivatives and pharmaceutical compositions containing such compounds are useful in inhibiting the chernotactic activation of neutrophils (PMN leukocytes) induced by the interaction of Interleukin-8 (IL-8) with CXCRI and CXCR2 membrane receptors. The compounds are used for the prevention and treatment of pathologies deriving from said activation. Notably, the selected sulfonic acids and their derivativas are devoid of cyclo-oxygenase inhibition activity and are particularly useful in the treatment of neutrofil-dependent pathologies such as psoriasis, ulcerative colitis, melanoma, chronic obstructive pulmonary disease (COPD), bullous pemphigoid, rheumatoid arthritis, idiopathic fibrosis, glomerulonephritis and in the prevention and treatment of damages caused by ischemia and reperfusion.
CoBr<sub>2</sub>(Bpy): An Efficient Catalyst for the Direct Conjugate Addition of Aryl Halides or Triflates onto Activated Olefins
method devoted to the directconjugateaddition of functionalized aryl compounds onto Michael acceptors is described. The CoBr2(2,2‘-bipyridine) complex appears to be an extremely suitable catalyst for the activation of a variety of aromatic reagents ranging fromhalides to triflates functionalized by reactive groups. This procedure allows for the synthesis of compounds resulting from 1,4-addition in good
