Grape Seed Proanthocyanidins: A Novel Source Of Dental Biomaterials And Unique Phytochemistry

Composite-based, tooth colored dental restorations, in spite of their aesthetic appeal, are limited by a short life span. Every subsequent restoration results in the loss of healthy dental tissue. Thus, a bio-mimetic approach has been developed to enhance the mechanical strength of dentin using plant-derived proanthocyanidins (PACs). From a panel of eight active plants, grape seed extract showed the highest dentin biomodification potential, a 15-fold enhancement of dentin stiffness measured in MPa.

Reviving NAPRALERT and Making It Ready For Improvement and New Challenges In Natural Products Chemistry and Pharmacognosy

NAPRALERT is a database on natural products, including data on the ethnobotany, chemistry, pharmacology, toxicology, and clinical trials. It was established in 1975 by the late Norman R. Farnsworth, at a time when computerized databases were just starting. It became web-accessible in 2005. Due to resource constraints, few enhancements were made to the existing database structure. Now, 10 years later, NAPRALERT faces the challenge of catching-up with other well-established resources.
