Abstract

Tuberculosis is part of a group named Neglected Diseases 2.0, which includes "The Big Three" diseases: Malaria, AIDS and Tuberculosis. Combined, they killed around six millions of people worldwide in the last year, according to World Health Organization. For this reason, they have been included in programs such as blue marble health, to encourage research, public policies and investment, as well as in the Global Fund to Fight AIDS, Tuberculosis and Malaria. Considering only tuberculosis, in 2015, 10.4 million of new cases were reported and 1.8 million of deaths were registered, putting it in the top of ten death causes in worldwide. Dendrimers, on the other hand, has shown a lot of biological application, especially as drug carriers. The dendrimer prodrug, planned by prodrug design, can be useful to improve the pharmacokinetics/pharmaceutical properties of a prototype. Considering that, the objective of this project is to synthesize a dendrimer prodrug containing isoniazid, being, therefore, potentially active in tuberculosis. The latent form will be composed by the first generation of polyamidoamine (PAMAM), succinic acid as spacer and the already mentioned isoniazid, which is one of the drug choice for the treatment of this disease. The main goal is to obtain a controlled drug delivery of the active drug, improving, therefore, the pharmacokinetics profile of the prototype. (AU)
