Products of Dental Use Containing Copaiba Oil-resin: Technological Prospecting Based on Patents

BACKGROUND

Copaiba oil-resin has been widely used and is especially found in neotropical regions, for which several pharmacological activities have been documented over the years. Prospective studies in intellectual property banks are important to increase competitiveness and thus generate new products in various research areas.

OBJECTIVE

A prospective study was carried out on patents of products containing copaiba oil-resin for dental use in intellectual property banks.

METHODS

The research was conducted with patent searches in six intellectual property banks of the world. Relevant information about the invention in the patent document was collected, processed and described.

RESULTS

The search found 9 patents using copaiba resin oil-resin in dental products. The National Institute of Industrial Property (INPI-Brazil) had the highest number of deposits (5), followed by Espacenet (2) and Free Patents (2). C. Langsdorffii was highlighted as the most widely used species in the products and deposits of vehicles in formulations (3). All the patents in the search are A61K code for medical, dental or hygienic purposes.

CONCLUSION

Most of the found patents are related to the area of Microbiology, specifically with application in Cariology. Brazil is represented by the INPI and presented the highest number of patent applications when compared to other intellectual property banks.

Biological Activities and Pharmacological Applications of Cyclodextrins Complexed with Essential Oils and Their Volatile Components: A Systematic Review

BACKGROUND

Essential oils (EOs) and their volatile components (VCs) have varied biological and pharmacological activities, but low solubility and bioavailability hamper their applications, so that inclusion in cyclodextrins (CDs) is likely to improve their physicochemical properties and pharmacological effects.

OBJECTIVE

The authors conducted a systematic review to evaluate the biological activities and pharmacological applications of essential oils and their volatile components complexed with cyclodextrins.

METHODS

The search terms 'Cyxlodextrin', 'Inclusion Complex', 'Volatile oils', 'Essential oil' and 'Volatile components' were used to retrieve articles from the PUBMED, MEDLINE and SCOPUS databases.

RESULTS

A total of 38 articles were identified. A greater efficacy of EOs and their VCs complexed with different CDs types was found in in vitro and preclinical studies when compared to free forms in the various biological activities and animal models of the evaluated pharmacological tests.

CONCLUSION

This review of selected studies showed that the use of CDs promotes greater solubility, bioavailability and efficacy of EOs and their VCs, thus indicating an interesting alternative for the biotechnological development of new therapeutic formulations.
