Despite the advancement in therapeutic and diagnostic procedures, breast cancer still represents a major challenge. Current anti-breast cancer approaches include surgical removal, radiotherapy, hormonal therapy and the use of various chemotherapeutic drugs. However, drug resistance, associated serious adverse effects, metastasis and recurrence complications still need to be resolved which demand safe and alternative strategies. In this scenario, phytochemicals have recently gained huge attention due to their safety profile and cost-effectiveness.

Although the biosynthetic pathway of resveratrol has been fully elucidated, the characterization of resveratrol-specific O-methyltransferases remains elusive. In this study, we used RNA-seq analysis to identify a putative aromatic O-methyltransferase gene, AcOMT1,inAcorus calamus. Recombinant AcOMT1 expressed in Escherichia coli showed high 40-O-methylation activity toward resveratrol and its derivative, isorhapontigenin. We purified a reaction product enzymatically formed from resveratrol by AcOMT1 and confirmed it as 40-O-methylresveratrol (deoxyrhapontigenin). Resveratrol and isorhapontigenin were the most preferred substrates with apparent Km values of 1.8 mM and 4.2 mM, respectively. Recombinant AcOMT1 exhibited reduced activity toward other resveratrol derivatives, piceatannol, oxyresveratrol, and pinostilbene. In contrast, re- combinant AcOMT1 exhibited no activity toward pterostilbene or pinosylvin. These results indicate that AcOMT1 showed high 40-O-methylation activity toward stilbenes with non-methylated phloroglucinol rings.

  • Resveratrol: Twenty Years of Growth, Development and Controversy
    Invited Review Biomol Ther 27(1), 1-14 (2019) Resveratrol: Twenty Years of Growth, Development and Controversy John M. Pezzuto* Arnold & Marie Schwartz College of Pharmacy and Health Sciences, Long Island University, Brooklyn, NY 11201, USA Abstract Resveratrol was first isolated in 1939 by Takaoka fromVeratrum grandiflorum O. Loes. Following this discovery, sporadic descrip- tive reports appeared in the literature. However, spurred by our seminal paper published nearly 60 years later, resveratrol became a household word and the subject of extensive investigation. Now, in addition to appearing in over 20,000 research papers, resveratrol has inspired monographs, conferences, symposia, patents, chemical derivatives, etc. In addition, dietary supple- ments are marketed under various tradenames. Once resveratrol was brought to the limelight, early research tended to focus on pharmacological activities related to the cardiovascular system, inflammation, and cancer but, over the years, the horizon greatly expanded. Around 130 human clinical trials have been (or are being) conducted with varying results. This may be due to factors such as disparate doses (ca. 5 to 5,000 mg/day) and variable experimental settings. Further, molecular targets are numerous and a dominant mechanism is elusive or nonexistent. In this context, the compound is overtly promiscuous. Nonetheless, since the safety profile is pristine, and use as a dietary supplement is prevalent, these features are not viewed as detrimental. Given the ongoing history of resveratrol, it is reasonable to advocate for additional development and further clinical investigation. Topical preparations seem especially promising, as do conditions that can respond to anti-inflammatory action and/or direct exposure, such as colon cancer prevention.

With the increasing incidence of multi-drugs infections, there is an urgent need to restock our antibiotic arsenal. Natural products are an invaluable source of inspiration in drug design and development. One of the most widely distributed groups of natural products in the plant kingdom is represented by stilbenoids. Stilbenoids are synthesised by plants as means of protection against pathogens, whereby the potential antimicrobial activity of this class of natural compounds has attracted great interest in the last years. The purpose of this review is to provide an overview of recent achievements in the study of stilbenoids as antimicrobial agents, with particular emphasis on the sources, chemical structures, and the mechanism of action of the most promising natural compounds. Attention has been paid to the main structure modifications on the stilbenoid core that have expanded the antimicrobial activity with respect to the parent natural compounds, opening the possibility of their further development. The collected results highlight the therapeutic versatility of natural and synthetic resveratrol derivatives and provide a prospective insight into their potential development as antimicrobial agents.

    The Study for Pterostibene Stability using Adaptable Vesicle Ji Hong Geun, Cho Se Hee , Kim Jeong Dong, Yu Hyo Gyoung 1 Jang Hye In 2 (1) H&A PharmaChem, R&D center, Bucheon-city, 421-837,Korea (2) Dep of oriental Medical and Herbal Cosmetic Science, Semyung University Objective: Pterostilbene is a stilbenoid chemically related to resveratrol . It is thought to be the key compound found predominantly in blueberries (as well as grapes ) that exhibit anti- cancer , anti-hypercholesterolemia , anti-hypertriglyceridemia properties, as well as fight off and reverse cognitive decline. It is believed that the compound also has anti- diabetic properties, but so far very little has been studied on this issue. Additionally, it is also touted as a potent anti-fungal. In these several years, as many people have been attracted by the functional cosmetics, there have been a lot of study to enhance the stability of active ingredients for light, heat, oxygen, etc. in the academic and industrial field. Especially, Pterostilbene is a powerful ingredient to reduce wrinkles, but its stability depends on environmental factors such as solvent, temperature, oxygen and light. Introduction A recent development in cosmetics has been the pursuit of high functionality. However, it is a common feature that the raw materials of functionality are unstable for light, heat and oxygen. Therefore, new technology of stabilization for functional raw material has been required. An inducible antifungal compound in grapevine leaves ( Vitis vinifera L., cv Cabernet-Sauvignon) has been identified as trans -pterostilbene (3,5-dimethoxy-4′- hydroxy stilbene). It is only a minor component of the phytoalexin response of V.

Plants containing resveratrol have been used effectively in traditional medicine for over 2000 years. It can be found in some plants, fruits, and derivatives, such as red wine. Therefore, it can be administered by either consuming these natural products or intaking nutraceutical pills. Resveratrol exhibits a wide range of beneficial properties, and this may be due to its molecular structure, which endow resveratrol with the ability to bind to many biomolecules.

  • Stilbene and Chalcone Synthases: Related Enzymes with Key
    Invited Trends Article Stilbene and Chalcone Synthases: Related Enzymes with Key Functions in Plant-Specific Pathways Joachim Schröder and Gudrun Schröder Institut für Biologie II, Universität Freiburg, Schänzlestraße 1, D-7800 Freiburg, Bundesrepublik Deutschland Z. N aturforsch. 45c, 1 -8 (1990); received N ovem ber 7, 1989 Several years of extensive research using the new powerful techniques of molecular biology have enabled the direct comparison of functionally or evolutionarily related genes and their products at the nucleotide and amino acid sequence levels. Two types of synthase with similar functions are discussed as an interesting example. Stilbene synthases, e.g. resveratrol synthase, produce the stilbene backbone as a key reaction in the biosynthesis of stilbene-type phyto­ alexins. Chalcone synthase is a key enzyme in the biosynthesis of flavonoids, including certain phytoalexins derived from a 6'-deoxychalcone which is synthesized by cooperation of chalcone synthase with a reductase. Resveratrol and chalcone synthases utilize the same substrates (4-coumaroyl-CoA and 3 molecules of malonyl-CoA) and catalyze the same condensing type of enzyme reaction (resulting in sequential addition of acetate units via malonyl-CoA), but the products differ in the newly formed ring systems (resveratrol and naringenin chalcone). A comparative analysis of cloned DNA sequences and of the reaction mechanisms indicates that the two enzymes are closely related. It seems likely that the proteins possess a common scaffold for substrate recognition and for the condensing reaction, and that the different folding of an enzyme-bound intermediate prior to closure of the new aromatic ring is responsible for the formation of the different products.
