Abstract
Bergenin (1), a unique fused C-glycoside isolated from Bergenia species, possesses interesting anti-inflammatory and antipain activities. To study SAR of this scaffold, first-generation derivatives were synthesized and evaluated for inhibition of lymphocyte proliferation and production of pro-inflammatory cytokines. The C-7 substituted derivatives showed inhibition of IL-6 as well as TNF-α production. Bergenin and its most potent IL-6 inhibitor derivatives 4e and 4f were then investigated in a panel of in vitro and in vivo inflammation/arthritis models. These compounds significantly decreased the expression of NF-kB and IKK-β in THP-1 cells. In in vivo study in BALB/c mice, a dose-dependent inhibition of SRBC-induced cytokines, reduction in humoral/cell-mediated immunity, and antibody titer was observed. The CIA study in DBA/1J mice indicated that compounds led to reduction in swelling of paws, cytokine levels, and anticollagen IgG1/IgG2a levels. The significant in vivo immunosuppressive efficacy of pyrano-isochromanones demonstrates the promise of this scaffold for development of next-generation antiarthritic drugs.

Abstract
In mass-spectrometry based peptide sequencing, formation of b- and y-type fragments by cleavage of the amide C-N bond constitutes the main dissociation pathway of protonated peptides under low-energy collision induced dissociation (CID). The structure of the b2 fragment ion from peptides containing glutamine (Gln) and asparagine (Asn) residues is investigated here by infrared ion spectroscopy using the free electron laser FELIX. The spectra are compared with theoretical spectra calculated using density functional theory for different possible isomeric structures as well as to experimental spectra of synthesized model systems. The spectra unambiguously show that the b2-ions do not possess the common oxazolone structure, nor do they possess the alternative diketopiperazine structure. Instead, cyclic imide structures are formed through nucleophilic attack by the amide nitrogen atom of the Gln and Asn side chains. The alternative pathway involving nucleophilic attack from the side-chain amide oxygen atom leading to cyclic isoimide structures, which had been suggested by several authors, can clearly be excluded based on the present IR spectra. This mechanism is perhaps surprising as the amide oxygen atom is considered to be the better nucleophile; however, computations show that the products formed via attack by the amide nitrogen are considerably lower in energy. Hence, b2-ions with Asn or Gln in the second position form structures with a five-membered succinimide or a six-membered glutarimide ring, respectively. b2-Ions formed from peptides with Asn in the first position are spectroscopically shown to possess the classical oxazolone structure.

Abstract
The total synthesis of (-)-julocrotine (1) starting from l-glutamic acid in 41% overall yield is described. The methodology utilizes protection, deprotection, and regioselection (carbonyl differentiation via oxazolidinone) protocols, and glutarimide ring formation is the key step.

Abstract
BACKGROUND Cellular infection with human immunodeficiency virus (HIV) both in vitro and in vivo requires a member of the chemokine receptor family to act as a co-receptor for viral entry. However, it is presently unclear to what extent the interaction of HIV proteins with chemokine receptors generates intracellular signals that are important for productive infection. RESULTS In this study we have used a recently described family of chemokine inhibitors, termed BSCIs, which specifically block chemokine-induced chemotaxis without affecting chemokine ligands binding to their receptors. The BSCI termed Peptide 3 strongly inhibited CCR5 mediated HIV infection of THP-1 cells (83 +/- 7% inhibition assayed by immunofluoresence staining), but had no effect on gp120 binding to CCR5. Peptide 3 did not affect CXCR4-dependent infection of Jurkat T cells. CONCLUSION These observations suggest that, in some cases, intracellular signals generated by the chemokine coreceptor may be required for a productive HIV infection.

Abstract
Inhibiting leukocyte recruitment is now a major focus in the design of novel anti-inflammatory drugs. Following the identification of lead compounds from conventional high-throughput screens using appropriate receptors or enzymes, it is important to validate the action of the compounds in a suitable in vitro model of leukocyte migration. Here, we review a range of different experimental approaches to modelling leukocyte migration, and identify the multi-well filter migration assay as the best compromise between the amount of resources required to screen multiple compounds and the amount of information gained about the effects of the compounds on cell movement behavior. However, there are pitfalls in the interpretation of data obtained using the multi-well filter migration assay, which arise from the imperfect correlation between the number of cells undergoing migration and the inhibitory activity of the test substances. We examine a number of such pitfalls and provide practical approaches to mitigate these problems as far as possible. We recommend a general strategy for screening inhibitors of cell migration using in vitro functional assays. While being more resource intensive than surrogate measures such as calcium flux, functional approaches nevertheless provide superior correlations with anti-inflammatory activity in vivo.

Abstract
Inappropriate inflammation is a component of a wide range of human diseases, including autoimmune disease, atherosclerosis, osteoporosis and Alzheimer's disease. Chemokines play an important role in orchestrating leukocyte recruitment during inflammation, and therefore represent an important target for anti-inflammatory therapies. Unfortunately, the chemokine system is complex, with about 50 ligands and 20 receptors, often acting with redundancy, making selection of appropriate specific antagonists difficult. One approach to overcoming this difficulty may be the development of broad-spectrum chemokine inhibitors (BSCIs). Here we review the present state of knowledge on BSCIs, including their activity in vitro and their anti-inflammatory effects in vivo, and discuss the future development of BSCIs as anti-inflammatory therapies for use in the clinic.

Abstract
Synthesis and evaluation of anti-inflammatory activity in rats with adjuvant arthritis of aryl sulfonyl derivatives of nonproteinogenic aromatic amino acids is reported. The studied compounds were synthesized by introducing residues of benzene-, p-toluene-, and p-bromobenzene sulfonic acids into threo-DL-phenylserine and erythro-DL-p-nitrophenylserine structures. From the set of 12 compounds tested in animal screening, N-(p-bromobenzenesulfonyl)-erythro-DL-p-nitrophenylserine ethyl ester 12 demonstrated the most pronounced anti-inflammatory activity. This compound inhibited inflammation process in polyarthritis phase by 53% (P < 0.001) though it was slightly toxic (LD50 > 6,000 mg kg(-1) for mice).
