Phenotypic Diversity in Cell Wall Lignocellulosic Constituents and Ethanol Yield of USDA Guayule and Mariola Germplasm [PDF]

Plants
Guayule (Parthenium argentatum A. Gray) is a valuable domestic source for rubber and resin. At its center of origin in the Northern Mexico and Southern Texas deserts, guayule, a perennial shrub, is hybridized with its relative species mariola (Parthenium

Synergistic Potential of Argentatins A and B to Improve 5-Fluorouracil Cytotoxicity in Colorectal Cancer Cell Models. [PDF]

J Cell Mol Med
ABSTRACT Colorectal cancer is the third most commonly diagnosed cancer worldwide and the second most common cause of cancer‐related death in both men and women. Although a number of treatments are available to combat this malignancy, the antimetabolite 5‐fluorouracil has been the cornerstone of therapy since its synthesis in the 1950s.

Rubber biosynthesis drives the biogenesis and development of rubber particles, the rubber-producing organelles. [PDF]

Plant Biotechnol J
Summary Rubber particles (RPs) are specialized organelles for the biosynthesis and storage of natural rubber in rubber‐producing plants. However, the mechanisms underlying the biogenesis and development of RPs remain unclear. In this study, two latex‐specific cis‐prenyltransferases (CPTs), TkCPT1 and TkCPT2, were identified in Taraxacum kok‐saghyz ...

Distribution of Rubber and Resins in Guayule [PDF]

Plant Physiology, 1947
Rubber contents are so frequently the focus of attention in investigations of guayule (Parthenium argent at urn Gray) that an account of rubber distribution in the plant may contribute to experimental studies as well as to purely descriptive literature concerning the plant.

A Higher Frequency Administration of the Nontoxic Cycloartane-Type Triterpene Argentatin A Improved Its Anti-Tumor Activity [PDF]

Molecules, 2020
Parthenium argentatum (Gray), commonly known as guayule, has been used to obtain natural rubber since the beginning of the 20th century. Additionally, the so called “resin” is a waste product derived from the industrial process.

Guayule (Parthenium argentatum) resin: A review of chemistry, extraction techniques, and applications

Industrial Crops and Products, 2021
Abstract Guayule (Parthenium argentatum Gray) is a perennial shrub of the Asteraceae family native to the arid southwestern U.S. and northern Mexico that produces high-quality, hypoallergenic natural rubber. Guayule processing produces three output streams: high-molecular weight rubber as the primary product, a mixture of resin/low-molecular weight ...

Semi-synthesis and cytotoxicity evaluation of pyrimidine, thiazole, and indole analogues of argentatins A–C from guayule (Parthenium argentatum) resin

Medicinal Chemistry Research, 2021
Argentatins A–C (1–3), the major cycloartane-type triterpenoids of guayule resin, a byproduct of commercial rubber production, were converted into their pyrimidine (7–12), thiazole (13–15), and indole (16–18) analogues by a molecular hybridization ...
