Abstract
Lactams are cyclic amides that are indispensable as drugs and as drug candidates. Conventional lactamization includes acid-mediated and coupling-agent-mediated approaches that suffer from narrow substrate scope, much waste, and/or high cost. Inexpensive, less-wasteful approaches mediated by highly electrophilic reagents are attractive, but there is an imminent risk of side reactions. Herein, a methods using highly electrophilic triphosgene in a microflow reactor that accomplishes rapid (0.5-10 s), mild, inexpensive, and less-wasteful lactamization are described. Methods A and B, which use N-methylmorpholine and N-methylimidazole, respectively, were developed. Various lactams and a cyclic peptide containing acid- and/or heat-labile functional groups were synthesized in good to high yields without the need for tedious purification. Undesired reactions were successfully suppressed, and the risk of handling triphosgene was minimized by the use of microflow technology.

Abstract
Diabetes has become the second most severe disease to human health. Probiotics are important for maintaining gastrointestinal homeostasis and energy balance and have been demonstrated to play a positive role in the prevention and treatment of metabolic syndromes, such as obesity, inflammation, dyslipidemia, and hyperglycemia. The objective of this study was to screen potential antidiabetic strains in vitro and evaluate its effects in vivo. For the in vitro section, dipeptidyl peptidase IV (DPP-IV) inhibitory and antioxidant activities of 14 candidate Lactobacillus spp. strains were tested. Then hydrophobicity and acid and bile salt tolerance assays were determined. The most promising in vitro strain was further evaluated for its antidiabetic properties in vivo using type 2 diabetes mice induced by high-fat diet and intraperitoneal injection of streptozotocin (STZ). The reference strain for this study was Lactobacillus rhamnosus GG. Results showed that cell-free excretory supernatants and cell-free extracts of Lactobacillus acidophilus KLDS1.0901 had better DPP-IV inhibitory activity, antioxidative activities, and biological characteristics than other strains. At the end of the treatment, we found that L. acidophilus KLDS1.0901 administration decreased the levels of fasting blood glucose (FBG), glycosylated hemoglobin, insulin in serum and AUCglucose, and increased the level of glucagon-like peptide 1 in serum compared with diabetic mice (p < 0.05). Moreover, L. acidophilus KLDS1.0901 supplementation increased the activities of superoxide dismutase, glutathione peroxidase, the level of glutathione, and reduced the level of malondialdehyde in serum. These results indicated that L. acidophilus KLDS1.0901 could be used as a potential antidiabetic strain; its application as food supplement and drug ingredient is thus recommended.

Abstract
UNLABELLED The incretin hormones are extremely rapidly metabolized by the ubiquitous enzyme dipeptidyl peptidase IV (DPP-IV). Therefore, DPP-IV inhibitors which can prolong the incretin effect are the newest and promising drugs for management of type 2 diabetes. In this study, we investigated whether Bifidobacteria colonizing the human gut possess DPP-IV inhibitory activity. Cell-free intracellular extracts of 13 Bifidobacterium strains isolated from breast-fed infant faecal samples were prepared and screened for DPP-IV inhibitory activity, and two Bifidobacterium strains-Bif. longum BBMN68 and Bif. lactis Bb12-were used as reference strains. Most of the strains showed varying levels of DPP-IV inhibitory property (7-27%). Strains of Bifidobacterium adolescentis IF1-11 and Bifidobacterium bifidum IF3-211 showed the greatest DPP-IV inhibitory activity (27 and 25%) as well as good in vitro probiotic properties. This initial finding suggested that new beneficial function of Bifidobacteria is strain-dependent and the strains or their components may have the potential application for management of type 2 diabetes via inhibiting gastrointestinal DPP-IV activity. Further investigations into the isolation and identification of the bioactive components of Bifidobacteria are warranted. SIGNIFICANCE AND IMPACT OF THE STUDY Our results show that Bifidobacteria isolated from breast-fed infants' faecal samples possess DPP-IV inhibitory activity. Strains of Bifidobacterium bifidum IF3-211 and Bifidobacterium adolescentis IF1-11, which showed excellent DPP-IV inhibitory properties as well as good in vitro probiotic properties, are expected to be beneficial for application as anti-diabetic probiotics.

Abstract
The proline-specific dipeptidyl aminopeptidase IV (DPP IV, DPP-4, CD26), widely expressed in mammalians, releases X-Pro/Ala dipeptides from the N-terminus of peptides. DPP IV is responsible of the degradation of the incretin peptide hormones regulating blood glucose levels. Several families of DPP IV inhibitors have been synthesized and evaluated. Their positive effects on the degradation of the incretins and the control of blood glucose levels have been demonstrated in biological models and in clinical trials. Presently, several DPP IV inhibitors, the "gliptins", are approved for type 2 diabetes or are under clinical evaluation. However, the gliptins may also be of therapeutic interest for other diseases beyond the inhibition of incretin degradation. In this Perspective, the biological functions and potential substrates of DPP IV enzymes are reviewed and the characteristics of the DPP IV inhibitors are discussed in view of type 2 diabetes and further therapeutic interest.

Abstract
Freidinger lactams, possessing a peptide bond configuration locked to Z, are important key elements of conformationally restricted peptidomimetics. In the present work, the C(α)H(i+1) unit has been replaced by N, leading to novel aza-Freidinger lactams. A synthesis to corresponding building blocks and their E-locked analogs is introduced. The versatile buildings blocks reported here are expected to serve as useful elements in peptide synthesis.

Abstract
Exploiting the incretin effect to develop new glucose-lowering treatments has become the focus of intense research. One successful approach has been the development of oral inhibitors of dipeptidyl peptidase-IV (DPP-IV). These drugs reversibly block DPP-IV-mediated inactivation of incretin hormones, for example, glucagon-like peptide 1 (GLP-1) and also other peptides that have alanine or proline as the penultimate N-terminal amino acid. DPP-IV inhibitors, therefore, increase circulating levels and prolong the biological activity of endogenous GLP-1, but whether this is sufficient to fully explain the substantial reduction in haemoglobin A(1c) (HbA(1c)) and associated metabolic profile remains open to further investigation. DPP-IV inhibitors such as vildagliptin and sitagliptin have been shown to be highly effective antihyperglycaemic agents that augment insulin secretion and reduce glucagon secretion via glucose-dependent mechanisms. This review summarizes the major clinical trials with DPP-IV inhibitors as monotherapy and as add-on therapy in patients with type 2 diabetes. The magnitude of HbA(1c) reduction with DPP-IV inhibitors depends upon the pretreatment HbA(1c) values, but there seems to be no change in body weight, and very low rates of hypoglycaemia and gastrointestinal disturbance with these agents. DPP-IV inhibitors represent a major new class of oral antidiabetic drug and their metabolic profile offers a number of unique clinical advantages for the management of type 2 diabetes.

Abstract
Dipeptidyl peptidase IV (DPIV) is an alpha,beta-hydrolase-like serine exopeptidase, which removes dipeptides, preferentially with a C-terminal l-Pro residue, from the N terminus of longer peptide substrates. Previously, we determined the tetrameric 1.8A crystal structure of native porcine DPIV. Each monomer is composed of a beta-propeller and a catalytic domain, which together embrace an internal cavity housing the active centre. This cavity is connected to the bulk solvent by a "propeller opening" and a "side opening". Here, we analyse DPIV complexes with a t-butyl-Gly-Pro-Ile tripeptide, Pro-boroPro, a piperazine purine compound, and aminoethyl phenyl sulfonylfluoride. The latter two compounds bind to the active-site groove in a compact and a quite bulky manner, respectively, causing considerable shifts of the catalytic Ser630 side-chain and of the Tyr547 phenolic group, which forms the oxyanion hole. The tripeptide, mimicking a peptide substrate, is clamped to the active site through tight interactions via its N-terminal alpha-ammonium group, the P2 carbonyl group, the P1-l-Pro side-chain, the C-terminal carboxylate group, and the stable orthoacid ester amide formed between the scissile peptide carbonyl group and Ser630 O(gamma). This stable trapping of the tripeptide could be due to stabilization of the protonated His740 imidazolium cation by the adjacent negatively charged C-terminal carboxylate group, preventing proton transfer to the leaving group nitrogen atom. Docking experiments with the compact rigid 58 residue protein aprotinin, which had been shown to be processed by DPIV, indicate that the Arg1-Pro2 N terminus can access the DPIV active site only upon widening of its side openings, probably by separation of the first and the last propeller blades, and/or of the catalytic and the propeller domain.

Abstract
CD26, a membrane-bound ectopeptidase, is known as an activated T cell marker with dipeptidyl peptidase IV (DPPIV) activity that has diverse functional roles in the regulation of peptide hormones, neuropeptides, chemokines and growth factors. We recently isolated a novel inhibitor of DPPIV, sulphostin, from culture broth of Streptomyces sp. MK251-43F3. We investigated herein the hematopoietic effect of sulphostin in mice and found that sulphostin induced the production of granulocyte colony-stimulating factor (G-CSF), stimulated myeloblasts in bone marrow, and increased neutrophil numbers in peripheral blood in both normal mice and mice with cyclophosphamide-induced leucopenia. Sulphostin desulfonate, in addition to sulphostin, has a similar inhibitory effect on DPPIV and stimulatory effect on neutrophils. These results suggest that DPPIV/CD26 might be a novel target for hematopoietic stimulation and DPPIV inhibitors including sulphostin and derivatives may be candidates for further development.
