Anticoronavirus Isoquinoline Alkaloids: Unraveling the Secrets of Their Structure-Activity Relationship. [PDF]

Influenza Other Respir Viruses
ABSTRACT Background Natural alkaloids are a structurally diverse class of bioactive compounds with significant therapeutic potential. This study aimed to evaluate the in vitro antiviral activity of various natural alkaloids against coronaviruses, clarify molecular effects via bioassays and docking, and explore structure–activity relationships.

Elucidating the enzyme network driving Amaryllidaceae alkaloids biosynthesis in Leucojum aestivum. [PDF]

Plant Biotechnol J
Schematic representation of Amaryllidaceae alkaloid biosynthesis in Leucojum aestivum. Norbelladine synthase (LaNBS) and noroxomaritidine/norcraugsodine reductase (LaNRII) catalyze the condensation of tyramine and 3,4‐dihydroxybenzaldehyde to form norbelladine, which is subsequently O‐methylated by norbelladine‐4′‐O‐methyltransferase (LaN4′OMT ...

Potential Therapeutic Applications of Plant‐Derived Alkaloids against Inflammatory and Neurodegenerative Diseases

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Alkaloids are a type of natural compound possessing different pharmacological activities. Natural products, including alkaloids, which originate from plants, have emerged as potential protective agents against neurodegenerative disorders (NDDs) and chronic inflammations. A wide array of prescription drugs are used against these conditions, however, not

Stress Response and Nutrient Homeostasis in Lettuce (Lactuca sativa) Exposed to Graphene Quantum Dots Are Modulated by Particle Surface Functionalization

Advanced Biology, Volume 5, Issue 4, April 2021., 2021
Graphene quantum dots (GQDs) induce antioxidative damage, alteration of phytohormone levels and mineral homeostasis, which eventually cause impaired photosynthesis and plant growth. Surface functionalization determines the reactive oxygen species generation and antioxidants oxidation capacity, which leads to different phytotoxicity of GQDs.

Generation of Oxidoreductases with Dual Alcohol Dehydrogenase and Amine Dehydrogenase Activity

Chemistry – A European Journal, Volume 27, Issue 10, Page 3315-3325, February 15, 2021., 2021
Lend me your hydrogen: Starting from an ϵ‐deaminating l‐lysine dehydrogenase, we created new variants that perform the reduction of aldehydes to alcohols and the reductive amination of aldehydes and ketones to amines. The reductive amination of ketones proceeded with excellent stereoselectivity.
