Abstract
Thiazole scaffold-based small molecules exhibit a range of biological activities and play important roles in drug discovery. Based on bioinformatics analysis, a putative biosynthetic gene cluster (BGC) for thiazole-containing compounds was identified from Streptomyces sp. SCSIO 40020. Heterologous expression of this BGC led to the production of eight new thiazole-containing compounds, grisechelins E, F, and I-N (1, 2, 5-10), and two quinoline derivatives, grisechelins G and H (3 and 4). The structures of 1-10, including their absolute configurations, were elucidated by HRESIMS, NMR spectroscopic data, ECD calculations, and single-crystal X-ray diffraction analysis. Grisechelin F (2) is a unique derivative, distinguished by the presence of a salicylic acid moiety. The biosynthetic pathway for 2 was proposed based on bioinformatics analysis and in vivo gene knockout experiments. Grisechelin E (1) displayed moderate antimycobacterial activity against Mycobacterium tuberculosis H37Ra (MIC of 8 μg mL-1).

Abstract
The highly diastereoselective 1,4-conjugate additions of several nitrogen nucleophiles to chiral bicyclic dehydroalanines have been assessed effectively at room temperature in good to excellent yields without needing any catalyst or additional base. This methodology is general, simple, oxygen and moisture tolerant, high-yielding, totally chemo- and stereoselective. This procedure offers an efficient and practical approach for the synthesis of Nβ-substituted α,β-diamino acids, such as 1-isohistidine, τ-histidinoalanine, β-benzylaminoalanine, β-(piperidin-1-yl)alanine, β-(azepan-1-yl)alanine, and fluorescent and ciprofloxacin-containing amino acid derivatives.

Abstract
Sulfur plays a critical role for the development and maintenance of life on earth, which is reflected by the wealth of primary metabolites, macromolecules, and cofactors bearing this element. Whereas a large body of knowledge has existed for sulfur trafficking in primary metabolism, the secondary metabolism involving sulfur has long been neglected. Yet, diverse sulfur functionalities have a major impact on the biological activities of natural products. Recent research at the genetic, biochemical, and chemical levels has unearthed a broad range of enzymes, sulfur shuttles, and chemical mechanisms for generating carbon-sulfur bonds. This Review will give the first systematic overview on enzymes catalyzing the formation of organosulfur natural products.

Abstract
The connection of microbial biosynthetic gene clusters to the small molecule metabolites they encode is central to the discovery and characterization of new metabolic pathways with ecological and pharmacological potential. With increasing microbial genome sequence information being deposited into publicly available databases, it is clear that microbes have the coding capacity for many more biologically active small molecules than previously realized. Of increasing interest are the small molecules encoded by the human microbiome, as these metabolites likely mediate a variety of currently uncharacterized human-microbe interactions that influence health and disease. In this mini-review, we describe the ongoing biosynthetic, structural, and functional characterizations of the genotoxic colibactin pathway in gut bacteria as a thematic example of linking biosynthetic gene clusters to their metabolites. We also highlight other natural products that are produced through analogous biosynthetic logic and comment on some current disconnects between bioinformatics predictions and experimental structural characterizations. Lastly, we describe the use of pathway-targeted molecular networking as a tool to characterize secondary metabolic pathways within complex metabolomes and to aid in downstream metabolite structural elucidation efforts.

Abstract
Bleomycins are a family of glycopeptide antibiotics that have the ability to bind and degrade DNA when bound to key metal ions, which is believed to be responsible for their antitumor activity. Knowledge of the structures of metallo-bleomycins is vital to further characterize their mechanism of action. To this end, numerous structural studies on metallo-bleomycins have been conducted. NMR spectroscopy has had a key role in most of these studies, and has led to very important findings involving the coordination chemistry of metallo-bleomycins, and the details of many metallo-bleomycin-DNA spatial correlations for this important drug. This paper reviews the most important contributions of NMR to the bleomycin field.

Abstract
The tallysomycins (TLMs) belong to the bleomycin (BLM) family of antitumor antibiotics. The BLM biosynthetic gene cluster has been cloned and characterized previously from Streptomyces verticillus ATCC 15003, but engineering BLM biosynthesis for novel analogs has been hampered by the lack of a genetic system for S. verticillus. We now report the cloning and sequencing of the TLM biosynthetic gene cluster from Streptoalloteichus hindustanus E465-94 ATCC 31158 and the development of a genetic system for S. hindustanus, demonstrating the feasibility to manipulate TLM biosynthesis in S. hindustanus by gene inactivation and mutant complementation. Sequence analysis of the cloned 80.2 kb region revealed 40 open reading frames (ORFs), 30 of which were assigned to the TLM biosynthetic gene cluster. The TLM gene cluster consists of nonribosomal peptide synthetase (NRPS) genes encoding nine NRPS modules, a polyketide synthase (PKS) gene encoding one PKS module, genes encoding seven enzymes for deoxysugar biosynthesis and attachment, as well as genes encoding other biosynthesis, resistance, and regulatory proteins. The involvement of the cloned gene cluster in TLM biosynthesis was confirmed by inactivating the tlmE glycosyltransferase gene to generate a TLM non-producing mutant and by restoring TLM production to the DeltatlmE::ermE mutant strain upon expressing a functional copy of tlmE. The TLM gene cluster is highly homologous to the BLM cluster, with 25 of the 30 ORFs identified within the two clusters exhibiting striking similarities. The structural similarities and differences between TLM and BLM were reflected remarkably well by the genes and their organization in their respective biosynthetic gene clusters.

Abstract
Preferential cleavage of Saccharomyces cerevisiae chromosomes in internucleosomal (linker) regions and nonspecific degradation of chromatin by an anticancer antibiotic which degrades DNA were investigated and found to increase in consecutive stages of growth. Cleavage of DNA in internucleosomal regions and intensities and multiplicities of nucleosomal bands were dependent on drug concentration, growth phase of the cells, and length of incubation. Cellular DNA was least degraded during logarithmic phase. After cells progressed only one generation in logarithmic phase, low concentrations (6.7 x 10(-7) to 3.4 x 10(-6) M) of bleomycin produced approximately three to seven times more DNA breaks. Internucleosomal cleavage was highest, and the most extended oligonucleosomal series and extensive chromatin degradation were observed during stationary phase. It is concluded that the growth phase of cells is critical in determining amounts of the highly preferential cleavage in internucleosomal regions and overall breakage and degradation of DNA. Mononucleosomal bands were most intense, indicating the greatest accumulation of DNA of this size. Mean mononucleosomal lengths were 165.9 +/- 3.9 base pairs, in agreement with yeast mononucleosomal lengths. As high-molecular-weight chromatin was digested by bleomycin, oligonucleosomes and, eventually, mononucleosomes became digested. Therefore, it is also concluded that bleomycin degradation of oligonucleosomes and trimming of DNA linker regions proceed to degradation of the monosomes (core plus linker DNA).

Abstract
Iron-57 Mössbauer, electron paramagnetic resonance (EPR) and H-1 nuclear magnetic resonance (NMR) studies of iron-bleomycin complexes in the pH range from 1.0 to 6.0 are reported. Sequential protonation of the ligands produces a variety of high-spin and low-spin complexes of the metal. Of particular interest is the reversible equilibrium between Fe(III)- and oxygen-stable Fe(II)-bleomycin. Below pH 3.5 Fe(II) complexes form, with maximal reduction occurring at approximately pH 2. At still lower pH, Fe(III) complexes unassociated with bleomycin become dominant. The observed reduction in the absence of exogenous reducing agents suggests the possible involvement of intramolecular autoreduction in bleomycin-mediated DNA degradation.

Abstract
The combined action of hyperthermia and Bleomycin on Aspergillus nidulans was studied at three different levels: mycelial protein synthesis, spore viability and induction of mutations. It was found that Bleomycin treatment of preincubated mycelia during the heat shock enhances the incorporation of 35S-methionine into heat shock bands. Furthermore, simultaneous treatment with hyperthermia (43 degrees C) and Bleomycin results in greater cytotoxic activity in spores and in a higher induction rate of point mutations.

Abstract
A rapid, linear gradient chromatographic technique for separating and quantifying copper(II)-chelated bleomycin congeners is described. This method is also capable of separating divalent from trivalent metal chelates; determining the purity of many chemically modified bleomycins; and assaying bleomycin hydrolase activity on complex mixtures. Quantification at 280 nm is sensitive to 50 pmol and is linear at least up to 10 nmol per injection.

Abstract
Bioactivation of a number of DNA-specific antitumor drugs depends on oxidoreduction. Bleomycin, neocarzinostatin and anthracycline glycosides are the best known among such drugs in terms of reductive activation processes. Their reduction results in short-lived radical or electrophilic intermediates attacking DNA stereospecifically. The physico-chemical properties of these drugs and the nature of DNA damage are reviewed. Models for DNA-intercalation, electron-donor systems involved in drug metabolisation, and the role of oxygen in radical reactions, are discussed in the light of recent reports.

Abstract
The acid-base titration of bleomycin-A2 in D2O solution at 35 +/- 5 degrees has been monitored by 13C n.m.r. spectroscopy at 67.89 MHz. The following pKDa values were obtained: 3.68 +/- 0.05 (secondary amine), 5.29 +/- 0.03 (imidazole), and 8.23 +/- 0.19 (primary amine), where KDa is the dissociation constant in D2O solution. The equilibrium isotope effects (pKDa--pKa in H2O) are: 0.70 +/- 0.06 (secondary amine), 0.28 +/- 0.04 (imidazole), and 0.85 +/- 0.19 (primary amine). Titration of the imidazole group of Bleo-A2 occurs at Npi, i.e. only Ntau is protonated in basic solution. Significant protonation shifts are almost completely limited to carbons of the N-terminal tetrapeptide, suggesting that the C-terminal tripeptide extends into the solvent and interacts to a minimal extent with the rest of the molecule. Long range protonation shifts associated with titration of the imidazole and secondary amine groups indicate that protonation of one or both of these sites is probably accompanied by significant conformational changes. The observed protonation shifts generally fail to correlate with Zn(II) complexation shifts reported by Dabrowiak et al. (1973, Biochemistry 17., 4090) indicating that ligation sites cannot unambiguously be determined from these complexation shifts. The complexation shifts previously attributed to coordination of the imidazole and carbamoyl groups probably result from conformational changes.

Abstract
In contrast to phage lambda the phages T3, T7 and T4 are not inhibited by as much as 150 microgram bleomycin/ml, while the chemically related antibiotic phleomycin increasingly inhibits the propagation of the phages in the order T4-T3-lambda. 20 microgram phleomycin/ml inhibit T3 by 95%. The resistance against bleomycin is surprising, because 10 microgram BM/ml block completely the colony-forming capacity of the host bacterium. The drug resistance of the phage growth correlates with the weak decrease of phage DNA synthesis, while the host cell DNA synthesis ceases rapidly. In accordance with these data is the in vivo inhibition of Escherichia coli cells and the in vitro degradation of their DNA. However, a contradiction exists between the in vivo resistance of T3 and T4 and the in vitro susceptibility of their DNA against nucleolytical fragmentation by bleomycin. The mechanism of the insensitivity of T3, T7 and T4 against bleomycin is unknown.

Abstract
The effect of Bleomycin on the semiconservative replication of mouse nuclear DNA has been studied. When asynchronously dividing mouse fibroblasts (L-cells) were grown in the presence of 5-bromodeoxyuridine (25 mg/l medium) for 18 h, three hybrid DNA bands with densities of 1.722, 1.752, and 1.761 kg/l appeared after caesium chloride density gradient centrifugation of nuclear DNA. In cells exposed to Bleomycin (100 mg/l) however, replication of satellite DNA is more strongly inhibited than is the replication of the main band DNA; preferentially the thymidinerich hybrid duplex at 1.761 kg/l could no longer be detected.

Abstract
The 1H NMR spectrum of the glycopeptide antineoplastic antibiotic bleomycin has been examined in D2O solution (Fourier transform nuclear magnetic resonance, 270 MHZ) and in H2O solution (correlation nuclear magnetic resonance, 250 MHZ). Resonances have been assigned to specific hydrogens of the two most abundant congeners, bleomycin-A2 (BLM-A2) and bleomycin-B2 (BLM-B2), on the basis of (1) homonuclear spin decoupling, (2) comparison of the spectra of BLM-A2, BLM-B2, fragments of these antibiotics, and the related antibiotic phleomycin, and (3) the pH dependence of chemical shifts. Resonance assignments are presented for all the CH protons of BLM-A2 and BLM-B2 except for the saccharide groups, for which only the anomeric proton assignments are given. All of the NH protons have been identified with specific resonances except for the two primary amide groups, which yield four well-resolved peaks, whose specific assignment was not attempted. This study serves as a basis for future investigations of the conformation of bleomycin and its interaction with metals and nucleic acids.

Abstract
Asynchronously dividing mouse fibroblasts (L-cells) treated with the antitumour antibiotic Bleomycin show various rather specific morphological alterations. Many of the cells exposed to bleomycin assume a more or less epitheloid cell shape and are larger than untreated cells; in addition to an increase in nuclear size these cells often contain multiple nuclei. In most of the cells nuclei show an almost complete loss of peripheral condensed chromatin. The nucleolar hypertrophy initially observed is followed by a shrinkage and segregation of the nucleolar components. The cytoplasmic alterations include dilatation of the cisternae of the rough endoplasmic reticulum as well as an increase of free, non membrane attached ribosomes, often arranged in spiral- and rosette-shaped polysomes; they are not specific for bleomycin.
