Bioorg Med Chem 2016; 24:3887-3892.

Abstract
Conjugation of cancer targeting peptides (CTPs) with small molecular therapeutics has emerged as a promising strategy to deliver potent (but typically nonspecific) cytotoxic agents selectively to cancer cells. Here we report the engineered production of a CTP (NGR)-containing C-1027 and evaluation of its activity against selected cancer cell lines. C-1027 is an enediyne chromoprotein produced by Streptomyces globisporus, consisting of an apo-protein (CagA) and an enediyne chromophore (C-1027). NGR is a CTP that targets CD13 in tumor vasculature. S. globisporus SB1026, a recombinant strain engineered to encode CagA with the NGR sequence fused at its C-terminus, directly produces the NGR-containing C-1027 that is equally active as the native C-1027. Our results demonstrate the feasibility to produce CTP-containing enediyne chromoproteins by metabolic pathway engineering and microbial fermentation and will inspire efforts to engineer other CTP-containing drug binding proteins for targeted delivery.

Abstract
Once considered to be isolation artifacts or chemical "mistakes" of nature, the number of naturally occurring organohalogen compounds has grown from a dozen in 1954 to >5000 today. Of these, at least 25% are halogenated alkaloids. This is not surprising since nitrogen-containing pyrroles, indoles, carbolines, tryptamines, tyrosines, and tyramines are excellent platforms for biohalogenation, particularly in the marine environment where both chloride and bromide are plentiful for biooxidation and subsequent incorporation into these electron-rich substrates. This review presents the occurrence of all halogenated alkaloids, with the exception of marine bromotyrosines where coverage begins where it left off in volume 61 of The Alkaloids. Whereas the biological activity of these extraordinary compounds is briefly cited for some examples, a future volume of The Alkaloids will present full coverage of this topic and will also include selected syntheses of halogenated alkaloids. Natural organohalogens of all types, especially marine and terrestrial halogenated alkaloids, comprise a rapidly expanding class of natural products, in many cases expressing powerful biological activity. This enormous proliferation has several origins: (1) a revitalization of natural product research in a search for new drugs, (2) improved compound characterization methods (multidimensional NMR, high-resolution mass spectrometry), (3) specific enzyme-based and other biological assays, (4) sophisticated collection methods (SCUBA and remote submersibles for deep ocean marine collections), (5) new separation and purification techniques (HPLC and countercurrent separation), (6) a greater appreciation of traditional folk medicine and ethobotany, and (7) marine bacteria and fungi as novel sources of natural products. Halogenated alkaloids are truly omnipresent in the environment. Indeed, one compound, Q1 (234), is ubiquitous in the marine food web and is found in the Inuit from their diet of whale blubber. Given the fact that of the 500,000 estimated marine organisms--which are the source of most halogenated alkaloids--only a small percentage have been investigated for their chemical content, it is certain that myriad new halogenated alkaloids are awaiting discovery. For example, it is estimated that nearly 4000 species of bryozoans have not been examined for their chemical content. The few species that have been studied contain some extraordinary halogenated alkaloids, such as hinckdentine A (610) and the chartellines (611-613). Of the estimated 1.5 million species of fungi, secondary metabolites have been characterized from only 5000 species. The future seems bright for the collector of halogenated alkaloids!

Abstract
Fijiolide A, a potent inhibitor of TNF-alpha-induced NFkappaB activation, along with fijiolide B, were isolated from a marine-derived bacterium of the genus Nocardiopsis. The planar structures of fijiolides A (1) and B (2) were elucidated by interpretation of 2D NMR spectroscopic data, while the absolute configurations of these compounds were defined by interpretation of circular dichroism and 2D NMR data combined with application of the advanced Mosher's method. Fijiolides A and B are related to several recently isolated chloroaromatic compounds, which appear to be the Bergman cyclization products of enediyne precursors. Fijiolide A reduced TNF-alpha-induced NFkappaB activation by 70.3%, with an IC(50) value of 0.57 micro-M. Fijiolide B demonstrated less inhibition, only 46.5%, without dose dependence. The same pattern was also observed with quinone reductase (QR) activity: fijiolide A was found to induce quinone reductase-1 (QR1) with an induction ratio of 3.5 at a concentration of 20 microg/mL (28.4 microM). The concentration required to double the activity was 1.8 microM. Fijiolide B did not affect QR1 activity, indicating the importance of the nitrogen substitution pattern for biological activity. On the basis of these data, fijiolide A is viewed as a promising lead for more advanced anticancer testing.

Abstract
The proposed structure of the maduropeptin chromophore, the biologically active component of the highly potent chromoprotein antitumor antibiotics, was stereoselectively synthesized but did not satisfy the spectra of the natural product. We demonstrated that the correct structure is diastereomeric, which possesses an antipodal sugar moiety.

Abstract
C-1027 is an enediyne antitumor antibiotic composed of four distinct moieties: an enediyne core, a deoxy aminosugar, a beta-amino acid, and a benzoxazolinate moiety. We now show that the benzoxazolinate moiety is derived from chorismate by the sequential action of two enzymes-SgcD, a 2-amino-2-deoxyisochorismate (ADIC) synthase and SgcG, an iron-sulfur, FMN-dependent ADIC dehydrogenase-to generate 3-enolpyruvoylanthranilate (OPA), a new intermediate in chorismate metabolism. The functional elucidation and catalytic properties of each enzyme are described, including spectroscopic characterization of the products and the development of a fluorescence-based assay for kinetic analysis. SgcD joins isochorismate (IC) synthase and 4-amino-4-deoxychorismate (ADC) synthase as anthranilate synthase component I (ASI) homologues that are devoid of pyruvate lyase activity inherent in ASI; yet, in contrast to IC and ADC synthase, SgcD has retained the ability to aminate chorismate identically to that observed for ASI. The net conversion of chorismate to OPA by the tandem action of SgcD and SgcG unambiguously establishes a new branching point in chorismate metabolism.

Abstract
C-1027 is an extremely potent antitumor agent that causes double-stranded DNA cleavages. It is a unique small molecule-protein complex composed of a highly reactive enediyne chromophore, which upon binding reacts with its target molecule DNA through radical-mediated hydrogen abstraction and an apoprotein that encapsulates the chromophore serving as its carrier to reach DNA. Although C-1027 has favorable properties as an effective drug delivery system, it slowly self-decomposes due to the reactivity of the chromophore toward the apoprotein. Understanding how the C-1027 destroys itself may enable design of its analogues that overcome this limitation. In this paper, mechanistic insights into the self-reactivity of C-1027 that facilitates its own decomposition are described. We provide evidence that the formation of the Gly96 radical, which promotes the oxidative protein scission and the subsequent chromophore release, is the major pathway for the self-decomposition of C-1027. On the basis of the newly isolated products of the self-decomposition, we propose that the apoprotein effectively protects two different structural elements of the chromophore that are essential for its biological activity: the nine-membered enediyne moiety (necessary for DNA cleavage) and the benzoxazine moiety (necessary for DNA intercalation). Using an engineered apoprotein analogue kinetically more stable toward the chromophore radical, we show that enhanced overall properties can be achieved for the natural C-1027 with respect to stability and antitumor activities. The results present the first example of a rationally designed C-1027 analogue reported to display superior in vitro antitumor activity to the natural C-1027. Our findings may have implications for design of proteins that can stably encapsulate highly reactive small molecules.

Abstract
C-1027 belongs to the family of chromoprotein antitumor antibiotics, which contain a carrier apoprotein and a highly unstable enediyne chromophore. The enediyne spontaneously aromatizes to generate p-benzyne biradical, and subsequently abstracts hydrogens from the DNA sugar backbone, resulting in cleavage of the double strand. Using spin-trapping methods, we obtained direct proof of radical intermediates during an DNA cleavage, and found intriguing difference in behavior between the trapping agents 2-methyl-2-nitrosopropane (MNP) and 5,5-dimethyl-1-pyrroline N-oxide (DMPO): MNP added to the sugar radicals of the DNA, whereas DMPO directly trapped a phenyl radical or p-benzyne biradical derived from the C-1027 chromophore.

Abstract
C-1027 is a potent antitumor agent with a previously undescribed molecular architecture and mode of action. Cloning and characterization of the 85-kilobase C-1027 biosynthesis gene cluster from Streptomyces globisporus revealed (i) an iterative type I polyketide synthase that is distinct from any bacterial polyketide synthases known to date, (ii) a general polyketide pathway for the biosynthesis of both the 9- and 10-membered enediyne antibiotics, and (iii) a convergent biosynthetic strategy for the C-1027 chromophore from four building blocks. Manipulation of genes governing C-1027 biosynthesis allowed us to produce an enediyne compound in a predicted manner.

Abstract
Benzoxazinoid acetal glucosides are a unique class of natural products abundant in Gramineae, including the major agricultural crops maize, wheat, and rye. These secondary metabolites are also found in several dicotyledonous species. Benzoxazinoids serve as important factors of host plant resistance against microbial diseases and insects and as allelochemicals and endogenous ligands. Interdisciplinary investigations by biologists, biochemists, and chemists are stimulated by the intention to make agricultural use of the benzoxazinones as natural pesticides. These natural products are not only constituents of a plant defense system but also part of an active allelochemical system used in the competition with other plants. This review covers biological and chemical aspects of benzoxazinone research over the last decade with special emphasis on recent advances in the elucidation of the biosynthetic pathway.
