As a continuation of the studies aimed at the development of new anticancer agents derived from the Amaryllidaceae alkaloid lycorine, 35 C1,C2-ether analogues of this natural product were synthesized. The compounds were evaluated for antiproliferative activities in vitro in a panel of tumor cell lines with varied levels of apoptosis resistance. A strong correlation between the compound lipophilicity and anticancer activity was observed, indicating that cell permeability properties must be an important determinant in the design of lycorine-based anticancer agents. A theoretical docking model, consistent with the experimental observations, is presented.

Non-small-cell lung cancer (NSCLC) stands as a primary contributor to cancer-related deaths worldwide. It has been demonstrated that Lycorine (LYD), a naturally occurring active sesquiterpene present in Chinese medicinal plants, exhibits anti-cancer properties across various cancer cell lines. However, the underlying mechanisms of LYD-induced anti-tumor in NSCLC are not fully known.

Plant alkaloids are used in a variety of medicines, such as anti-cancer drugs and analgesics. Among these plant alkaloids, galanthamine is an Amaryllidaceae type alkaloid with acetylcholinesterase inhibition activity used in the treatment of neurological diseases such as Alzheimer's disease. Although the chemical synthesis of galanthamine has been successfully achieved, is the main source of its production.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common liver disease worldwide and few drugs are available for its treatment. Lycorine has effective anti-inflammatory and lipid-lowering effects, but the impact on MASLD is not fully understood. In this study, we intend to test the intervention effect of lycorine on MASLD.

Aggregation of TAR-DNA binding protein-43 (TDP-43) is a pathological feature present in nearly 97 % cases of amyotrophic lateral sclerosis (ALS), making it an attractive target for pathogenic studies and drug screening. Here, we have performed a high-throughput screening of 1500 compounds from a natural product library and identified that lycorine, a naturally occurring alkaloid, significantly decreases the level of TDP-43 in a cellular model. We further demonstrate that lycorine reduces the level of TDP-43 both through inhibiting its synthesis and by promoting its degradation by the ubiquitin-proteasome system (UPS).
