Two series of andrographolide derivatives with introduction of amide moiety into ring A by Beckmann rearrangement were synthesized. In series 1, the ring A was converted to caprolactam, and an amide moiety was linked to C-19 of ring A in series 2. Among them, compound 8h exhibited obvious inhibition
Andrographolide (1) is a major diterpene lactone exhibiting anti-inflammatory effects and is found in the plant Andrographis paniculata (Burm. f) Nees, which is widely used in Traditional Chinese Medicine. Synthesis of more effective drugs from andrographolide is very interesting and can prove to be
Two novel epimerized andrographolides, 8,17-dihydro-7,8-dehydroandrographolide and 10β-8,17-dihydro-7,8-dehydroandrographolide, were isolated from andrographolide sulfonates. Their structures were elucidated by detailed NMR analysis, single-crystal X-ray diffraction and quantum chemical ECD
Covalent drugs with prolonged actions often show superior potency, yet integrated strategies for optimizing their structural and electronic features are lacking. Herein, we present our effort directed towards understanding the contribution of chemical reactivity to biological potency to rationally
Andrographolide (AG) is a chemical entity from traditional Chinese herbs and its oral pills have been applied to the treatment of respiratory inflammation. Here we report pulmonary delivery of liposomal AG dry powder inhalers (LADPIs) for treatment of Staphylococcus aureus-induced pneumonia. AG
The aim of this article is to study how andrographolide-releasing collagen scaffolds influence rabbit articular chondrocytes in maintaining their specific phenotype under inflammatory environment. Physical blending combined with vacuum freeze-drying method was utilized to prepare the
Andrographolide is a main bioactive diterpene lactone in A. paniculata with anti-inflammatory activity. In this study, a series of andrographolide derivatives were synthesized and evaluated for their structure-anti-inflammatory activity relationships in vivo. Among all compounds, isoandrographolide
Inflammation and oxidative stress are two major factors that are involved in the pathogenesis of atherosclerosis. A smart drug delivery system that responds to the oxidative microenvironment of atherosclerotic plaques was constructed in the present study. Andrographolide-loaded micelle was assembled
Diabetic nephropathy (DN) is characterized by proliferation of mesangial cells, mesangial hypertrophy and extracellular matrix (ECM) accumulation. Our recent study found that andrographolide inhibited high glucose-induced mesangial cell proliferation and fibronectin expression through inhibition of
Abdominal aortic aneurysm (AAA), characterized by exuberant inflammation and tissue deterioration, is a common aortic disease associated with a high mortality rate. There is currently no established pharmacological therapy to treat this progressive disease. Andrographolide (Andro), a major bioactive
Andrographolide is a major bioactive labdane diterpenoid isolated from Andrographis paniculata and has protective effects against cigarette smoke (CS)-induced lung injury. This study was done to determine whether such protective effects were mediated through modulation of microRNA (miR)-218
BACKGROUND
Andrographolide (Andro) is the main compound distributed in medicinal herb Andrographis paniculata. This study aims to observe the amelioration of Andro on streptozotocin (STZ)-induced diabetic retinopathy (DR) in mice.
METHODS
STZ-induced non-proliferative DR (NPDR) for 2 months and
Andrographolide (1), an active constituent of Andrographis paniculata, decreased tumor necrosis factor-α (TNF-α)-induced intercellular adhesion molecule-1 (ICAM-1) expression and adhesion of HL-60 cells onto human umbilical vein endothelial cells (HUVEC), which are associated with inflammatory
BACKGROUND
Andrographolide (Andro) is a main active ingredient of the natural plant Andrographis paniculata, which has special effects on bacterial infections and inflammatory diseases.
OBJECTIVE
We previously synthesized Andrographolide derivatives AL-1 and investigated its anti-inflammatory
Our group recently reported novel anti-inflammatory effects of andrographolide (2), a bioactive molecule isolated from Andrographis paniculata, in a mouse asthma model. However, 2 has been shown to possess cytotoxic activity. 14-Deoxy-11,12-didehydroandrographolide (1) is an analogue of 2 that can
