  • Costunolide—A Bioactive Sesquiterpene Lactone with Diverse Therapeutic Potential
    Review Costunolide—A Bioactive Sesquiterpene Lactone with Diverse Therapeutic Potential Dae Yong Kim 1 and Bu Young Choi 2,* 1 Department of Biology Education, Seowon University, Cheongju, Chungbuk 361-742, So Korea; [email protected] 2 Department of Pharmaceutical Science & Engineering, Seowon University, Cheongju, Chungbuk 361-742, South Korea * Correspondance: [email protected]; Tel.: +82-043-299-8411 Received: 23 April 2019; Accepted: 12 June 2019; Published: 14 June 2019 Abstract: Sesquiterpene lactones constitute a major class of bioactive natural products. One of the naturally occurring sesquiterpene lactones is costunolide, which has been extensively investigated for a wide range of biological activities. Multiple lines of preclinical studies have reported that the compound possesses antioxidative, anti-inflammatory, antiallergic, bone remodeling, neuroprotective, hair growth promoting, anticancer, and antidiabetic properties. Many of these bioactivities are supported by mechanistic details, such as the modulation of various intracellular signaling pathways involved in precipitating tissue inflammation, tumor growth and progression, bone loss, and neurodegeneration. The key molecular targets of costunolide include, but are not limited to, intracellular kinases, such as mitogen-activated protein kinases, Akt kinase, telomerase, cyclins and cyclin-dependent kinases, and redox-regulated transcription factors, such as nuclear factor-kappaB, signal transducer and activator of transcription, activator protein-1. The compound also diminished the production and/expression of proinflammatory mediators, such as cyclooxygenase-2, inducible nitric oxide synthase, nitric oxide, prostaglandins, and cytokines. This review provides an overview of the therapeutic potential of costunolide in the management of various diseases and their underlying mechanisms. Keywords: costunolide; antioxidants; anti-inflammatory; anti-allergic; bone regenerating; neuroprotective; antimicrobial; hair growth promoting; anticancer; antidiabetic properties 1.

Eelco Wallaart2 Plant Research International, Business Unit Cell Cybernetics, P.O. Box 16, 6700 AA Wageningen, The Netherlands (H.J.B., J.K., F.W.A.V.); Department of Organic Chemistry, Hamburg University, D–20146 Hamburg, Germany (I.G.A.); Department of Organic Chemistry, Wageningen Agricultural University, Dreijenplein 8, 6703 HB Wageningen, The Netherlands (J.-W.d.K.); and University Centre for Pharmacy, Department of Pharmaceutical Biology, University of Groningen, Antonius Deusinglaan 1, 9713 AV Groningen, The Netherlands (T.E.W.) Chicory (Cichorium intybus) sesquiterpene lactones were recently shown to be derived from a common sesquiterpene intermediate, (ϩ)-germacrene A. Germacrene A is of interest because of its key role in sesquiterpene lactone biosynthesis and because it is an enzyme-bound intermediate in the biosynthesis of a number of phytoalexins. Using polymerase chain reaction with degenerate primers, we have isolated two sesquiterpene synthases from chicory that exhibited 72% amino acid identity. Heterologous expression of the genes in Escherichia coli has shown that they both catalyze exclusively the formation of (ϩ)-germacrene A, making this the first report, to our knowledge, on the isolation of (ϩ)-germacrene A synthase (GAS)-encoding genes. Northern analysis demonstrated that both genes were expressed in all chicory tissues tested albeit at varying levels. Protein isolation and partial purification from chicory heads demonstrated the presence of two GAS proteins. On MonoQ, these proteins co-eluted with the two heterologously produced proteins.

  • Biochemical and Functional Characterization of Induced Terpene Formation in Arabidopsis Roots
    Biochemical and Functional Characterization of Induced Terpene Formation in Arabidopsis Roots Reza Sohrabi Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Biological Sciences Dorothea Tholl, Committee Chair Glenda Gillaspy Khidir Hilu John Jelesko July 23rd 2013 Blacksburg Virginia Keywords: Cytochrome P450, plant volatiles, specialized metabolism, root chemical defense, Arabidopsis iii Biochemical and Functional Characterization of Induced Terpene Formation in Arabidopsis Roots Reza Sohrabi ABSTRACT Plants have evolved a variety of constitutive and induced chemical defense mechanisms against biotic stress. Emission of volatile compounds from plants facilitates interactions with both beneficial and pathogenic organisms. However, knowledge of the chemical defense in roots is still limited. In this study, we have examined the root-specific biosynthesis and function of volatile terpenes in the model plant Arabidopsis. When infected with the root rot pathogen Pythium irregulare, Arabidopsis roots release the acyclic C11-homoterpene (E)-4,8- dimethylnona-1,3,7-triene (DMNT), which is a common constituent of volatile blends emitted from insect-damaged foliage. We have identified a single cytochrome P450 monooxygenase of the CYP705 family that catalyzes a root-specific oxidative degradation of the C30-triterpene precursor arabidiol thereby causing the release of DMNT and a C19-degradation product named arabidonol. We found that DMNT shows inhibitory effects on P. irregulare mycelium growth and oospore germination in vitro, and that DMNT biosynthetic mutant plants were more susceptible to P. irregulare infection. We provide evidence based on genome synteny and phylogenetic analysis that the arabidiol biosynthetic gene cluster containing the arabidiol synthase (ABDS) and CYP705A1 genes possibly emerged via local gene duplication followed by iv de novo neofunctionalization.

Most terpenes, flavonoids and alkaloids require P450 catalytic functions to reach their biological activity. In the last ten years, several efforts have focused on the expression and production of these three main types of secondary metabolites in engineered microorganisms and plants using P450 of ethnobotanical origin. Despite this, several P450 coding sequences from plant sources are discovered yearly but only a few have been screened by functional genomics. Amongst them, only a few have shown potentials for use in sustainable production of novel drugs and highly valuable products.
