Dominican Republic grants two invention patents for cancer treatment

By Guzmán Ariza, Attorneys at Law

The National Office of Industrial Property of the Dominican Republic (ONAPI) granted two invention patents to Quirico Castillo, a researcher and professor from the Autonomous University of Santo Domingo UASD.

The UASD is one of the country’s top hubs for scientific knowledge and new technologies, with research areas that cover natural sciences, engineering, humanities, medicine, education and economics.

In the last years the university has begun a transformation with the need of moving from the invention to the certification of scientific work through patent management. Such challenge has the support of the World Intellectual Property Organization (WIPO) Technology and Innovation Support Center (TISC), a program that provides innovators in developing countries with access to locally based, high quality technology information and related services, helping them to exploit their innovative potential and to create, protect, and manage their intellectual property rights.

The university has make immense contributions to the development of a research culture in the Dominican Republic. Mr. Castillo, in particular, has carried out important research with the aim of identifying cancer treatments. One of those is related to anticancer biological activity in Dominican species of the Asteraceae family. 

Mr. Castillo, along with a team of researchers, worked on five human cell lines, two breast cancer lines, one colon cancer line, one cervical cancer line, and another lung cancer line. The most important finding of his research, entitled "Anticancerous Bioprospecting in Dominican Species of the Asteraceae Family," is that the plant with the greatest anticancer activity is Eupatorium illitum.
