Toxicity and Neurotoxic Eﬀects of Monoterpenoids: In Insects and Earthworms

Abstract

e insecticidal activity of several monoterpenoids from essential oils was evaluated against insect pests. Toxicity tests illustrated the bioactivity of d-limonene, α-terpineol, β-myrcene, linalool, and pulegone against insects, including the house ﬂy, the German cockroach, the rice weevil, and the western corn rootworm. Bioassays were conducted to assess their toxicity via topical application, fumigation, ingestion, and ovicidal exposures. Growth, reproduction and repellency were also evaluated in the German cockroach. Non-invasive electrophysiological recordings were used with an earthworm to investigate neurotoxic eﬀects of the monoterpenoids. Relevant monoterpenoid bioassay results in the literature are also discussed.

Terpenoids Commonly Found in Cannabis Sativa Do Not Modulate the Actions of Phytocannabinoids Or Endocannabinoids on TRPA1 and TRPV1 Channels

Cannabis and Cannabinoid Research Volume 5, Number 4, 2020 Mary Ann Liebert, Inc. DOI: 10.1089/can.2019.0099 Terpenoids Commonly Found in Cannabis sativa Do Not Modulate the Actions of Phytocannabinoids or Endocannabinoids on TRPA1 and TRPV1 Channels Marika Heblinski,1,2 Marina Santiago,3 Charlotte Fletcher,1,4 Jordyn Stuart,1,3,4 Mark Connor,3 Iain S. McGregor,1,4 and Jonathon C. Arnold1,2,* Abstract Introduction: Cannabis sativa produces hundreds of bioactive compounds, including cannabinoids and terpe- noids. It has been proposed that cannabinoids act in synergy with terpenoids to produce the entourage effect, a concept used to explain the therapeutic benefits of medicinal cannabis. One molecular explanation for the en- tourage effect is that the terpenoids augment the actions of cannabinoids at their molecular drug targets in cells. We recently reported that terpenoids commonly found in cannabis do not influence the functional effects of D9-tetrahydrocannabinol (D9-THC) on cannabinoid 1 and cannabinoid 2 receptors. The present study aimed to extend on this research by examining whether terpenoids influence the effects of phytocannabinoids and endo- cannabinoids on human transient receptor potential ankyrin 1 (hTRPA1) and human transient receptor potential vanilloid 1 (hTRPV1) channels heterologously expressed in mammalian cells. Materials and Methods: The activity of terpenoids, phytocannabinoids, and endocannabinoids was assessed in inducible HEK Flp-In T-Rex cells transfected with hTRPA1 and hTRPV1 channels, respectively. Real-time changes in intracellular calcium ([Ca]i) were measured using the Calcium 5 dye and a FlexStation 3 plate reader. Results: a-pinene, b-pinene, b-caryophyllene, linalool, limonene, b-myrcene or a-humulene did not affect [Ca]i in hTRPA1 and hTRPV1 overexpressing cells.

Abstract: Polymers are essential materials in our daily life. The synthesis of value-added polymers is mainly performed from fossil fuel-derived monomers. However, the adoption of the circular economy model based on the bioeconomy will reduce the dependence on fossil fuels. In this context, bioreﬁneries have emerged to convert biomass into bioenergy and produce high value- added products, including molecules that can be further used as building blocks for the synthesis of biopolymers and bioplastics.

Abstract Purpose: To evaluate the impact of systemic cyclophosphamide treatment on the rat uterus and investigate the potential therapeutic effects of natural antioxidant preparations curcumin and capsaicin against cyclophosphamide side effects. Methods: A 40 healthy adult female Wistar albino rats were used in this study. Rats were randomly divided into four groups to determine the effects of curcumin and capsaicin against Cyclophosphamide side effects on the uterus (n=10 in each group); Group 1 was the control group (sham-operated), Group 2 was the cyclophosphamide group, Group 3 was the cyclophosphamide + curcumin (100mg/kg) group, and Group 4 was the cyclophosphamide + capsaicin (0.5 mg/kg) group. Results: Increased tissue oxidative stress and histological damage in the rat uterus were demonstrated due to the treatment of systemic cyclophosphamide chemotherapy alone. The level of tissue oxidant and antioxidant markers and histopathological changes were improved by the treatment of curcumin and capsaicin.
Living Polymerization of Renewable Vinyl Monomers Into Bio-Based Polymers

Polymer Journal (2015) 47, 527–536 & 2015 The Society of Polymer Science, Japan (SPSJ) All rights reserved 0032-3896/15 www.nature.com/pj FOCUS REVIEW Controlled/living polymerization of renewable vinyl monomers into bio-based polymers Kotaro Satoh1,2 In this focused review, I present an overview of our recent research on bio-based polymers produced by the controlled/living polymerization of naturally occurring or derived renewable monomers, such as terpenes, phenylpropanoids and itaconic derivatives. The judicious choice of initiating system, which was borrowed from conventional petrochemical monomers, not only allowed the polymerization to proceed efficiently but also produced well-defined controlled/living polymers from these renewable monomers. We were able to find several controlled/living systems for renewable monomers that resulted in novel bio-based polymers, including a cycloolefin polymer, an AAB alternating copolymer with an end-to-end sequence, a phenolic and high-Tg alternating styrenic copolymer, and an acrylic thermoplastic elastomer.

Isoprene, Terpenes and Natural Alkenes and Alkynes

ISOPRENE, TERPENES AND NATURAL ALKENES AND ALKYNES ETHYLENE The simplest alkene, ethene, is produced naturally by all higher plants from the amino acid methionine and is a plant growth regulator. It causes trees to lose their leaves and stems to thicken. It is best known for its ability to ripen fruit and is responsible for the accelerated ripening of fruit confined in bags or in the presence of ripe fruits. ISOPRENE AND TERPENES Some of the most interesting naturally occurring compounds originate from 2-methyl-1,3- butadiene, otherwise known as isoprene, in plants; the isoprene itself is synthesized from acetate. Pyrophosphate esters of isoprene are the actual reagents for these construction projects; pyrophosphoric acid is an anhydride of phosphoric acid. O OH O O OH O P P O P P O O O OH O O OH isoprene isopentenyl pyrophosphate geranyl pyrophosphate ---> ---> squalene The isoprene units are always linked 1,4 and head-to-tail in terpenes (the preferred addition orientation even in mineral acid), but are often linked further in bizarre ways to produce rings. Oxygen functional groups are often included, as might be expected from hydrolysis of the pyrophosphate linkage. The diversity of compounds produced is amazing, but the pattern of one methyl group every fourth carbon reveals their origin. The simplest, monoterpenes, consist of 2 isoprene units. The stereoisomers of these simplest terpenes provide interesting illustrations of the stereospecificity of odor receptors; for example (+)-(S)-carvone is responsible for the odor of caraway and (-)-(R)-carvone the odor of spearmint. O OH O myrcene geraniol limonene carvone camphor pinene Sesquiterpenes (1.5 terpenes) have 3 isoprene units and diterpenes have 4.

Central Effects of Citral, Myrcene and Limonene, Constituents of Essential Oil Chemotypes from Lippia Alba (Mill.) N.E

Phytomedicine 9: 709–714, 2002 © Urban & Fischer Verlag http://www.urbanfischer.de/journals/phytomed Phytomedicine Central effects of citral, myrcene and limonene, constituents of essential oil chemotypes from Lippia alba (Mill.) N.E. Brown T. Gurgel do Vale, E. Couto Furtado, J. G. Santos Jr., and G. S. B. Viana Department of Physiology and Pharmacology, Faculty of Medicine, Federal University of Ceará, Fortaleza, Brazil Summary Citral, myrcene and limonene (100 and 200 mg/kg body wt., i.p.), constituents of essential oils from Lippia alba chemotypes, decreased not only the number of crossings but also numbers for rearing and grooming, as measured by the open-field test in mice. Although muscle relaxation detected by the rota rod test was seen only at the highest doses of citral (200 mg/kg body wt.) and myrcene (100 and 200 mg/kg body wt.), this effect was observed even at the lowest dose of limonene (50 mg/kg body wt.). Also, citral and myrcene (100 and 200 mg/kg body wt.) increased barbiturate sleeping time as compared to control. Limonene was also effective at the highest dose, and although citral did not increase the onset of sleep, it increased the duration of sleep, which is indicative of a poten- tiation of sleeping time. Citral (100 and 200 mg/kg body wt.) increased 2.3 and 3.5 times, respec- tively, the barbiturate sleeping time in mice. Similar effects were observed for myrcene and limonene at the highest dose (200 mg/kg body wt.) which increased the sleeping time around 2.6 times. In the elevated-plus maze, no effect was detected with citral up to 25 mg/kg body wt., while at a high dose it decreased by 46% the number of entries in the open arms.
