Further investigation on the phytochemistry of the medicinal plant Stephania viridiflavens led to the isolation of a new naturally occurring aporphine alkaloid, (+)-6R, 6aS-isocorydine N(beta)-oxide (1), together with three known aporphine alkaloids: (+)-6R, 6aS-corydine N(beta)-oxide (2), (+)-N-methyl-laurotetanine (3) and (+)-stepharine (4). The structure and stereochemistry of 1 were determined on the basis of spectroscopic methods and confirmed by synthesis. Alkaloids 2-4 were isolated for the first time from this species.

How well is the female population represented in clinical trials with infusion therapies for Parkinson's disease? A systematic review and metanalysis.
Eur J Neurol
January 2025
Parkinson and Movement Disorders Unit, Study Center for Neurodegenerative diseases (CESNE), Department of Neuroscience, Padua Neuroscience Center (PNC), University of Padua, Padua, Italy.
Background: Parkinson's disease (PD) is a neurodegenerative disorder affecting both sexes, but differences exist between male and female in clinical manifestations, functional impact of symptoms and hormonal influences. Therefore, representativeness of females in PD trials indirectly determines the external validity of the clinical research in this field.
Objective: To estimate the representativeness of female in infusion therapy trials for advanced PD.
Challenges of equitable access to device-aided therapies for advanced Parkinson's Disease in Poland - expert consensus and treatment recommendations.
Neurol Neurochir Pol
December 2024
Department of Neurological-Psychiatric Nursing, Faculty of Health Sciences, Medical University of Gdansk, Gdansk, Poland.
Introduction: In Poland, not all forms of device-aided therapies for advanced Parkinson's Disease (APD) are currently available.
Material And Methods: We aimed to produce a consensus recommendation from Polish movement disorders experts after discussing gaps in the APD care pathway in Poland.
Results: Rescue therapy with apomorphine (APO) PEN injection and levodopa-entacapone-carbidopa intestinal gel infusion are not included in Poland's Specialist Therapeutic Programme, and are thus not reimbursed.
Integrating network pharmacology and animal experimental validation to investigate the mechanism of lotus leaf in obesity.
Int Immunopharmacol
January 2025
Heilongjiang Academy of Traditional Chinese Medicine, PR China. Electronic address:
Background: Lotus leaf and its extracts have been reported to exert various beneficial effects; however, their anti-obesity mechanisms remain relatively unclear. Therefore, we investigated the mechanism by which lotus leaf regulates obesity using network pharmacology, molecular docking, and animal experimentation.
Methods: Network pharmacology was used to identify potential targets and pathways through which lotus leaf regulates obesity.
Cholera is a dreadful disease. The scourge of this deadly disease is still evident in the developing world. Though several therapeutic strategies are in practice to combat and contain the disease, there is still a need for new drugs to control the disease safely and effectively.
