Summary: Six inclusion complexes based on sulfobutyl-beta-cyclodextrin and lycorine hydrochloride were prepared and characterized. The complexes showed excellent encapsulation effect, likely due to the electrostatic interaction between the sulfonic group of sulfobutyl-beta-cyclodextrin and the quaternary amino group of lycorine hydrochloride. Furthermore, the complexes exhibited pH-sensitive drug release, good solubility, stability, and blood compatibility, suggesting their potential as suitable drug carriers.

Summary: A RuPHOX/Pd catalyzed asymmetric allylic substitution cascade of α-carbonylamides with an allylic meso-dicarbonate has been developed to synthesize chiral 3-acyl bicyclolactams bearing three vicinal carbon stereocenters in high yields. The products exhibited excellent enantioselectivity with up to 99% ee and high diastereoselectivity with >20:1 dr. Mechanistic studies revealed a dynamic kinetic resolution process during the second step of the cascade reaction, which contributed to the high diastereoselectivity. The protocol can be scaled up and the resulting products are versatile for further transformations, especially in the synthesis of natural products.

Summary: This study found that lycorine (LYC) has a protective effect against doxorubicin (ADR)-induced cardiotoxicity and exerts its effects through the SIRT1/PPAR gamma signaling pathway. The results provide a theoretical basis for the development of LYC as a potential cardioprotective drug.

Summary: Snowdrop, an iconic early spring flowering plant of the genus Galanthus (Amaryllidaceae), is economically important as an ornament and has gained scientific and commercial interest due to the discovery of Galanthamine as a treatment for Alzheimer's disease. This review discusses the bioactivities of Galanthus spp including anticholinesterase, antimicrobial, antioxidant, and anticancer potential, highlighting their potential for drug discovery and nutraceutical development.

Summary: This study evaluates the effect of LYC pre- and post-treatment in a septic mouse model and its potential mechanism. LYC pretreatment attenuates myocardial injury by improving survival rate, sepsis score, blood indicators, cardiac function, inhibiting inflammation and oxidative stress, improving mitochondrial function, modulating ER stress, and activating AMPK pathway. LYC posttreatment also has slight protective effects on septic myocardial injury, but not as ideal as pretreatment.

Summary: The study identified an ABC transporter LaABCB11 from Lycoris aurea that functions in the transport of lycorine, potentially playing a role in the translocation and accumulation of lycorine from leaves and bulbs to roots. The transporter increased yeast cells' tolerance to lycorine and reduced lycorine accumulation in transformants compared to control or mutant yeast. LaABCB11 was found to be associated with the plasma membrane and mainly expressed in the phloem of leaves and bulbs, as well as in the cortical cells of roots.

Summary: A small molecule called lycorine was discovered to inhibit the SREBF pathway through a novel mechanism without inducing ER stress or activating NR1H3, improving dyslipidemia and fatty liver disease. Lycorine promotes SCAP lysosomal degradation through the SQSTM1-mediated autophagy-independent lysosomal degradation (SMAILD) pathway, leading to SCAP degradation without autophagy.

Summary: Pancreatic cancer is a highly metastatic and lethal tumor with a low survival rate. The lack of effective drugs in clinical settings is a major factor contributing to the high mortality. This study found that lycorine, a small molecule derived from a traditional Chinese medicinal herb, inhibited the growth and metastasis of pancreatic cancer cells, reduced neovascularization, and enhanced sensitivity to gemcitabine. The mechanism of action involves the degradation of Notch1 oncoprotein and downregulation of key vasculogenic genes.

Summary: This article reviews and discusses the effects and mechanisms of lycorine in the treatment of multi-organ dysfunction, especially sepsis. By regulating autophagy and inducing cancer cell apoptosis, as well as exhibiting anti-inflammatory, antifungal, antiviral, antimalarial, and antitumor effects, lycorine can ameliorate organ damage. Research has found that lycorine has an important effect on organ damage in sepsis. Lycorine, as a promising natural organ protective agent, provides a new theoretical basis for the treatment of organ protection, especially in sepsis.

Summary: Chiral transition metal complexes with privileged ligands are efficient catalysts for various asymmetric organic transformations. Transition metal complexes of C1-symmetric pyrrolidine-based ligands have been widely used in asymmetric organic reactions. However, a comprehensive review article on the transition metal complexes of chiral C1-symmetric pyrrolidine-based ligands derived from (L)-proline has not been published.
