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
Calcineurin inhibitors induce nephrotoxicity through poorly understood mechanisms thereby limiting their use in transplantation and other diseases. Here we define a microRNA (miRNA)-messenger RNA (mRNA) interaction map that facilitates exploration into the role of miRNAs in cyclosporine-induced nephrotoxicity (CIN) and the gene pathways they regulate. Using photoactivatable ribonucleoside-enhanced crosslinking and immunoprecipitation (PAR-CLIP), we isolated RNAs associated with Argonaute 2 in the RNA-induced silencing complex (RISC) of cyclosporine A (CsA) treated and control human proximal tubule cells and identified mRNAs undergoing active targeting by miRNAs. CsA causes specific changes in miRNAs and mRNAs associated with RISC, thereby altering post-transcriptional regulation of gene expression. Pathway enrichment analysis identified canonical pathways regulated by miRNAs specifically following CsA treatment. RNA-seq performed on total RNA indicated that only a fraction of total miRNAs and mRNAs are actively targeted in the RISC, indicating that PAR-CLIP more accurately defines meaningful targeting interactions. Our data also revealed a role for miRNAs in calcineurin-independent regulation of JNK and p38 MAPKs caused by targeting of MAP3K1. Together, our data provide a novel resource and unique insights into molecular pathways regulated by miRNAs in CIN. The gene pathways and miRNAs defined may represent novel targets to reduce calcineurin induced nephrotoxicity.

Abstract
Only about 100 natural products are known to contain a nitrogen-sulfur (N-S) bond. This review thoroughly categorizes N-S bond-containing compounds by structural class. Information on biological source, biological activity, and biosynthesis is included, if known. We also review the role of N-S bond functional groups as post-translational modifications of amino acids in proteins and peptides, emphasizing their role in the metabolism of the cell.

Abstract
Natural products have always been exploited to promote health and served as a valuable source for the discovery of new drugs. In this review, the great potential of natural compounds and medicinal plants for the treatment or prevention of cardiovascular and metabolic disorders, global health problems with rising prevalence, is addressed. Special emphasis is laid on natural products for which efficacy and safety have already been proven and which are in clinical trials, as well as on plants used in traditional medicine. Potential benefits from certain dietary habits and dietary constituents, as well as common molecular targets of natural products, are also briefly discussed. A glimpse at the history of statins and biguanides, two prominent representatives of natural products (or their derivatives) in the fight against metabolic disease, is also included. The present review aims to serve as an "opening" of this special issue of Molecules, presenting key historical developments, recent advances, and future perspectives outlining the potential of natural products for prevention or therapy of cardiovascular and metabolic disease.

Abstract
Phosphoric triamides have extensive applications in biochemistry and are also used as O-donor ligands. Four new mixed-amide phosphoric triamide structures, namely rac-N-tert-butyl-N',N''-dicyclohexyl-N''-methylphosphoric triamide, C17H36N3OP, (I), rac-N,N'-dicyclohexyl-N'-methyl-N''-(p-tolyl)phosphoric triamide, C20H34N3OP, (II), N,N',N''-tricyclohexyl-N''-methylphosphoric triamide, C19H38N3OP, (III), and 2-[cyclohexyl(methyl)amino]-5,5-dimethyl-1,3,2λ(5)-diazaphosphinan-2-one, C12H26N3OP, (IV), have been synthesized and studied by X-ray diffraction and spectroscopic methods. Structures (I) and (II) are the first diffraction studies of acyclic racemic mixed-amide phosphoric triamides. The P-N bonds resulting from the different substituent -N(CH3)(C6H11), (C6H11)NH-, 4-CH3-C6H4NH-, (tert-C4H9)NH- and -NHCH2C(CH3)2CH2NH- groups are compared, along with the different molecular volumes and electron-donor strengths. In all four structures, the molecules form extended chains through N-H...O hydrogen bonds.

Abstract
It has previously been shown that inhibition of CD26 (DPPIV/dipeptidylpeptidase IV) peptidase activity improves homing of hematopoietic stem cells (HSCs) to the bone marrow and increases engraftment efficiency. Here, we demonstrate that treatment of retrovirally transduced mouse bone marrow cells with the tri-peptide Diprotin A (Ile-Pro-Ile), a specific inhibitor of CD26, significantly enhances engraftment of retrovirally transduced HSCs. Treatment of transduced bone marrow cells with Diprotin A permitted long-term expression of a retrovirally encoded MHC class I gene on multiple hematopoietic cell lineages after transplantation of a suboptimal number of transduced cells. Secondary transfer experiments revealed that expression of the transduced MHC class I gene resulted from engraftment of transduced HSCs. Expression of the allogeneic MHC class I antigen on bone marrow-derived cells following transplantation of Diprotin A-treated cells was sufficient to induce transplantation tolerance. Therefore, inhibition of CD26 activity significantly enhances engraftment of limited numbers of genetically modified HSCs, resulting in physiologically relevant levels of gene transfer.

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.

Abstract
The structure of sulphostin (1), a novel dipeptidyl peptidase IV (DPP-IV) inhibitor, is consisted of three key functional groups, including a characteristic amino(sulfoamino)phosphinyl group, on a piperidine ring. To examine the relationship between its structure and the inhibitory activity against DPP-IV, various analogues were synthesized and their activities were investigated. These results indicated that all of the functional groups on the piperidine ring were crucial to the DPP-IV inhibitory activity of sulphostin, and that the sulfonic acid group, which constructed the amino(sulfoamino)phosphinyl group, contributed to the stability of the compound. Moreover, those functional groups should be adjoined on the piperidine ring for the inhibitory activity. The size of the nitrogen-containing heterocyclic ring including piperidine appeared to scarcely affect the activity. In the present study, the sulfonic acid-deficient five-membered ring analogue 27a showed the strongest inhibitory activity (IC50=11 nM).
