Nicotiana tabacum: From a Beneficial Plant to Harmful Products-A Comprehensive Review of Smokeless Tobacco and Its Adverse Health Effects. [PDF]
ScientificWorldJournalNicotiana tabacum is a cash crop that originated in America and was introduced to the world by Christopher Colombus. It is now cultivated in many countries with major producers including China, the USA, India, and Brazil. The plant was widely used by the indigenous people of America for different reasons (spiritual, hallucination, and medical).

GeroScience, 2020 Terpenes and their derivatives have been used conventionally as potential dietary supplements to boost the nutritional value of endless food products. Several plant-based complex terpenoid and their derivatives have been reported for a wide range of medicinal and nutritional properties. However, their simple counterparts, whose production is relatively

Biochemical Characterization and Homology Modeling of Methylbutenol Synthase and Implications for Understanding Hemiterpene Synthase Evolution in Plants [PDF]
Journal of Biological Chemistry, 2011 2-Methyl-3-buten-2-ol (MBO) is a five-carbon alcohol produced and emitted in large quantities by many species of pine native to western North America. MBO is structurally and biosynthetically related to isoprene and can have an important impact on regional atmospheric chemistry.

New Coumarin-Hemiterpene Ether Glucosides and a Structurally Related Phenylpropanoic Acid Derivative from Artemisia Armeniaca [PDF]
Natural Product Communications, 2010 Two new coumarin-hemiterpene ether glucosides, 4’- O-(β-D-glucopyranosyl) desoxylacarol (1), and 5- O-(β-D-glucopyranosyl) lacarol (2), were isolated from the methanolic extract of the aerial parts of Artemisia armeniaca Lam. Their structures were established by means of spectroscopic analysis including 1

Hymenosides A-F, Six New Hemiterpene Glucosides from the Japanese Fern Hymenophyllum barbatum.
Chemical and Pharmaceutical Bulletin, 2001 In the course of investigation of the bitter-tasting substances of the Japanese fern Hymenophyllum barbatum belonging to the family Hymenophyllaceae, six new hemiterpene glucosides called hymenosides A-F (1-6) have been isolated from the methanol extract, together with an acyclic bis-bibenzyl derivative, perrottetin H.

Anaerobic Production of Isoprene by Engineered Methanosarcina Species Archaea
Applied and Environmental Microbiology, 2021 A significant barrier to implementing renewable chemical technologies is high production costs relative to those for petroleum-derived products. Existing technologies using engineered organisms have difficulty competing with petroleum-derived chemicals ...

ChemBioChem, 2019 Abstract Isoprenoids are a large class of natural products with wide‐ranging applications. Synthetic biology approaches to the manufacture of isoprenoids and their new‐to‐nature derivatives are limited due to the provision in nature of just two hemiterpene building blocks for isoprenoid biosynthesis.

New Bitter-Tasting Hemiterpene Glycosides from the Japanese Fern Hymenophyllum barbatum.
Chemical and Pharmaceutical Bulletin, 2001 Hymenosides G--J were newly isolated from the Japanese fern Hymenophyllum barbatum, in addition to hymenosides A--F. The structures of hymenosides were elucidated by extensive two-dimensional nuclear magnetic resonance and/or chemical evidence. The structures of those aglycones were divided into three types, 1,4-dihydroxy-2-hydroxymethyl-but-2-ene, 1,4-
