Cocos nucifera (L.) (Arecaceae) is commonly called the "coconut tree" and is the most naturally widespread fruit plant on Earth. Throughout history, humans have used medicinal plants therapeutically, and minerals, plants, and animals have traditionally been the main sources of drugs. The constituents of C. nucifera have some biological effects, such as antihelminthic, anti-inflammatory, antinoc...

Co-Cultures of porcine articular cartilage and synovium or synovial conditioned medium were used as an in vitro model to mimic inflammatory events at the cartilage/synovial junction in degenerative joint disease. This model provides a useful tool to assess the anti-inflammatory and antiarthritic properties of pharmacological agents. In this study the effects of copper and zinc on (i) PG synthes...

Increased cell apoptosis in chondrocytes is a feature of degenerative cartilage. Astragaloside IV (AST) has been proven to possess an antiarthritic effect by preventing interleukin (IL)‑1β‑induced cartilage damage. However, the role of AST on chondrocyte apoptosis and its underlying mechanism remains unknown. In the present study, degenerative chondrocytes isolated from patients with osteoarthr...

Cannabidiol (CBD) is a component of cannabis, which does not cause the typical marijuana-type effects, but has a high potential for use in several therapeutic areas. In contrast to Δ(9)-tetrahydrocannabinol (Δ(9)-THC), it binds very weakly to the CB1 and CB2 cannabinoid receptors. It has potent activity in both in vitro and in vivo anti-inflammatory assays. Thus, it lowers the formation of tumo...

Intraarticular gene transfer of cyclin-dependent kinase (CDK) inhibitors to suppress synovial cell cycling has shown efficacy in treating animal models of rheumatoid arthritis. Endogenous CDK inhibitors also modulate immune function via a CDK-independent pathway. Accordingly, systemic administration of small molecules that inhibit CDK may or may not ameliorate arthritis. To address this issue, ...

A questionnaire method was designed for dog owners to monitor the orthopedic disabilities of their pets for evaluation of a nutraceutical with joint health claims. Fifty large-breed dogs, 7 to 12 years of age, presenting with signs of osteoarthritis, were randomly allocated to placebo and active treatment groups. Degree of disability was assessed by physical examination, a standard questionnair...

The effects of steroidal and non-steroidal anti-inflammatory drugs on the established lesion of type II collagen induced arthritis in rats were evaluated by measuring the hind paw oedema and anti-type II collagen antibody titre. Dexamethasone, a steroidal anti-inflammatory drug, reduced the anti-type II collagen antibody titre and markedly suppressed the established lesion of type II collagen i...

The genus Artocarpus (Moraceae) comprises about 50 species of evergreen and deciduous trees. Economically, the genus is of appreciable importance as a source of edible fruit, yield fairly good timber and is widely used in folk medicines. The aim of the present review is to present comprehensive information of the chemical constituents, biological and pharmacological research on Artocarpus which...

Ehretia laevis Roxb. (Boraginaceae) has been extensively used as a traditional remedy for the treatment of diverse range ailments related to respiratory system, gastrointestinal tract, reproductive and against several infections. This review critically assesses documents, first time, fragmented information on E. laevis, including its botanical description, folklore uses, bioactive phyto metabol...

Naturally occurring benzophenones represent a relatively small group of plant metabolites with narrow distribution, mainly in members Clusiaceae, Gentianaceae, Hypericaceae, Polygalaceae, Myrtaceae, etc.; however, there were reports several compounds derived from microorganisms belonging to the Aspergillaceae and Valsaceae families propolis. Benzophenones exhibit many biological activities, suc...
