Nonbiomimetic total synthesis of indole alkaloids using alkyne-based strategies [PDF]

open access: yes, 2021
Biomimetic natural product synthesis is generally straightforward and efficient because of its established feasibility in nature and utility in comprehensive synthesis, and the cost-effectiveness of naturally derived starting materials. On the other hand,

Enantioselective synthesis of indole alkaloids from chiral lactams [PDF]

open access: yes, 2020
This account reports on the use of (R)- or (S)-phenylglycinol- and (S)-tryptophanol-derived oxazolopiperidone lactams as building blocks for the enantioselective synthesis of structurally diverse indole alkaloids.

From nature to nanoscale: advances, challenges, and preclinical translation of nanofiber drug delivery systems containing plant‐derived active ingredients

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Since the early 1960s, nanotechnology has been a critical area of science, allowing for the development of sophisticated nanomaterials. Nanofibers, one of the most widely used nanotechnological drug delivery systems, have emerged as a highly versatile platform within modern pharmaceutical sciences.

Beyond a dual role: how Purpureocillium lilacinum reprograms citrus metabolism for integrated biocontrol and growth promotion

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.
