  • Tropinone Synthesis Via an Atypical Polyketide Synthase and P450-Mediated Cyclization
    ARTICLE DOI: 10.1038/s41467-018-07671-3 OPEN Tropinone synthesis via an atypical polyketide synthase and P450-mediated cyclization Matthew A. Bedewitz 1, A. Daniel Jones 2,3, John C. D’Auria 4 & Cornelius S. Barry 1 Tropinone is the first intermediate in the biosynthesis of the pharmacologically important tropane alkaloids that possesses the 8-azabicyclo[3.2.1]octane core bicyclic structure that defines this alkaloid class. Chemical synthesis of tropinone was achieved in 1901 but the 1234567890():,; mechanism of tropinone biosynthesis has remained elusive. In this study, we identify a root- expressed type III polyketide synthase from Atropa belladonna (AbPYKS) that catalyzes the formation of 4-(1-methyl-2-pyrrolidinyl)-3-oxobutanoic acid. This catalysis proceeds through a non-canonical mechanism that directly utilizes an unconjugated N-methyl-Δ1-pyrrolinium cation as the starter substrate for two rounds of malonyl-Coenzyme A mediated decarbox- ylative condensation. Subsequent formation of tropinone from 4-(1-methyl-2-pyrrolidinyl)-3- oxobutanoic acid is achieved through cytochrome P450-mediated catalysis by AbCYP82M3. Silencing of AbPYKS and AbCYP82M3 reduces tropane levels in A. belladonna. This study reveals the mechanism of tropinone biosynthesis, explains the in planta co-occurrence of pyrrolidines and tropanes, and demonstrates the feasibility of tropane engineering in a non- tropane producing plant. 1 Department of Horticulture, Michigan State University, East Lansing, MI 48824, USA. 2 Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, MI 48824, USA. 3 Department of Chemistry, Michigan State University, East Lansing, MI 48824, USA. 4 Department of Chemistry & Biochemistry, Texas Tech University, Lubbock, TX 79409, USA.

  • The Identification of Human Aldo-Keto Reductase AKR7A2 As a Novel
    Li et al. Cellular & Molecular Biology Letters (2016) 21:25 Cellular & Molecular DOI 10.1186/s11658-016-0026-9 Biology Letters SHORTCOMMUNICATION Open Access The identification of human aldo-keto reductase AKR7A2 as a novel cytoglobin- binding partner Xin Li, Shanshan Zou, Zhen Li, Gaotai Cai, Bohong Chen, Ping Wang and Wenqi Dong* * Correspondence: [email protected] Abstract Department of Biopharmaceutics, School of Laboratory Medicine and Cytoglobin (CYGB), a member of the globin family, is thought to protect cells from Biotechnology, Southern Medical reactive oxygen and nitrogen species and deal with hypoxic conditions and University, 1838 North Guangzhou oxidative stress. However, its molecular mechanisms of action are not clearly Avenue, Guangzhou 510515, China understood. Through immunoprecipitation combined with a two-dimensional electrophoresis–mass spectrometry assay, we identified a CYGB interactor: aldo-keto reductase family 7 member A2 (AKR7A2). The interaction was further confirmed using yeast two-hybrid and co-immunoprecipitation assays. Our results show that AKR7A2 physically interacts with CYGB. Keywords: CYGB, AKR7A2, Protein-protein interactions, Yeast two-hybrid assay, Co-immunoprecipitation, 2-DE, Oxidative stress Introduction Cytoglobin (CYGB), which is a member of the globin family, was discovered more than a decade ago in a proteomic screen of fibrotic liver [1]. It was originally named STAP (stellate activating protein). Human CYGB is a 190-amino acid, 21-kDa protein [2], encoded by a single copy gene mapped at the 17q25.3 chromosomal segment [3]. It has a compact helical conformation, giving it the ability to bind to heme, which allows reversible binding of gaseous, diatomic molecules, including oxygen (O2), nitric oxide (NO) and carbon monoxide (CO), just like hemoglobin (Hb), myoglobin (Mb) and neuroglobin (Ngb) [4].

  • Reactive Carbonyls and Oxidative Stress: Potential for Therapeutic Intervention ⁎ Elizabeth M
    Pharmacology & Therapeutics 115 (2007) 13–24 www.elsevier.com/locate/pharmthera Associate editor: R.M. Wadsworth Reactive carbonyls and oxidative stress: Potential for therapeutic intervention ⁎ Elizabeth M. Ellis Strathclyde Institute of Pharmacy and Biomedical Sciences, University of Strathclyde, 204 George Street, Glasgow, G1 1XW, United Kingdom Abstract Reactive aldehydes and ketones are produced as a result of oxidative stress in several disease processes. Considerable evidence is now accumulating that these reactive carbonyl products are also involved in the progression of diseases, including neurodegenerative disorders, diabetes, atherosclerosis, diabetic complications, reperfusion after ischemic injury, hypertension, and inflammation. To counter carbonyl stress, cells possess enzymes that can decrease aldehyde load. These enzymes include aldehyde dehydrogenases (ALDH), aldo-keto reductases (AKR), carbonyl reductase (CBR), and glutathione S-transferases (GST). Some of these enzymes are inducible by chemoprotective compounds via Nrf2/ ARE- or AhR/XRE-dependent mechanisms. This review describes the metabolism of reactive carbonyls and discusses the potential for manipulating levels of carbonyl-metabolizing enzymes through chemical intervention. © 2007 Elsevier Inc.

  • Supplementary Methods
    Supplementary methods Human lung tissues and tissue microarray (TMA) All human tissues were obtained from the Lung Cancer Specialized Program of Research Excellence (SPORE) Tissue Bank at the M.D. Anderson Cancer Center (Houston, TX). A collection of 26 lung adenocarcinomas and 24 non-tumoral paired tissues were snap-frozen and preserved in liquid nitrogen for total RNA extraction. For each tissue sample, the percentage of malignant tissue was calculated and the cellular composition of specimens was determined by histological examination (I.I.W.) following Hematoxylin-Eosin (H&E) staining. All malignant samples retained contained more than 50% tumor cells. Specimens resected from NSCLC stages I-IV patients who had no prior chemotherapy or radiotherapy were used for TMA analysis by immunohistochemistry. Patients who had smoked at least 100 cigarettes in their lifetime were defined as smokers. Samples were fixed in formalin, embedded in paraffin, stained with H&E, and reviewed by an experienced pathologist (I.I.W.). The 413 tissue specimens collected from 283 patients included 62 normal bronchial epithelia, 61 bronchial hyperplasias (Hyp), 15 squamous metaplasias (SqM), 9 squamous dysplasias (Dys), 26 carcinomas in situ (CIS), as well as 98 squamous cell carcinomas (SCC) and 141 adenocarcinomas. Normal bronchial epithelia, hyperplasia, squamous metaplasia, dysplasia, CIS, and SCC were considered to represent different steps in the development of SCCs. All tumors and lesions were classified according to the World Health Organization (WHO) 2004 criteria. The TMAs were prepared with a manual tissue arrayer (Advanced Tissue Arrayer ATA100, Chemicon International, Temecula, CA) using 1-mm-diameter cores in triplicate for tumors and 1.5 to 2-mm cores for normal epithelial and premalignant lesions.

Tropane and Granatane Alkaloid Biosynthesis: A Systematic Analysis Abstract The tropane and granatane alkaloids belong to the larger pyrroline and piperidine classes of plant alkaloids, respectively. Their core structures share common moieties and their scattered distribution among angiosperms suggest that their biosynthesis may share common ancestry in some orders, while they may be independently derived in others. Tropane and granatane alkaloid diversity arises from the myriad modifications occurring ot their core ring structures. Throughout much of human history, humans have cultivated tropane- and granatane-producing plants for their medicinal properties. This manuscript will discuss the diversity of their biological and ecological roles as well as what is known about the structural genes and enzymes responsible for their biosynthesis.

Selective AKR1C3 inhibitors are required because compounds should not inhibit the highly related AKR1C1 and AKR1C2 isoforms which are involved in the inactivation of 5α-dihydrotestosterone. NSAIDs, N-phenylanthranilates in particular, are potent but nonselective AKR1C3 inhibitors. Using flufenamic acid, 2-{[3-(trifluoromethyl)phenyl]amino}- benzoic acid, as lead compound, five classes of structural analogues were synthesized and evaluated for AKR1C3 inhibitory potency and selectivity. Structure−activity relationship (SAR) studies revealed that a meta-carboxylic acid group relative to the amine conferred pronounced AKR1C3 selectivity without loss of potency, while electron withdrawing groups on the phenylamino B-ring were optimal for AKR1C3 inhibition. Lead compounds did not inhibit COX-1 or COX-2 but blocked the AKR1C3 mediated production of testosterone in LNCaP-AKR1C3 cells. These compounds offer promising leads toward new therapeutics for CRPC.
