Drug/Lead Compound Hydroxymethylation as a Simple Approach to Enhance Pharmacodynamic and Pharmacokinetic Properties.

Hydroxymethylation is a simple chemical reaction, in which the introduction of the hydroxymethyl group can lead to physical-chemical property changes and offer several therapeutic advantages, contributing to the improved biological activity of drugs. There are many examples in the literature of the pharmaceutical, pharmacokinetic, and pharmacodynamic benefits, which the hydroxymethyl group can confer to drugs, prodrugs, drug metabolites, and other therapeutic compounds. It is worth noting that this group can enhance the drug's interaction with the active site, and it can be employed as an intermediary in synthesizing other therapeutic agents.

Malaria and tuberculosis as diseases of neglected populations: state of the art in chemotherapy and advances in the search for new drugs.

Malaria and tuberculosis are no longer considered to be neglected diseases by the World Health Organization. However, both are huge challenges and public health problems in the world, which affect poor people, today referred to as neglected populations. In addition, malaria and tuberculosis present the same difficulties regarding the treatment, such as toxicity and the microbial resistance.

Perspectives About Self-Immolative Drug Delivery Systems.

Self-immolative drug delivery system is one of the delivery systems, which have drawn attention, in recent research, highlighting the improvement they generate in drug selectivity and efficacy. Self-immolative linkers, or spacers, are covalent groups, which have the role of cleavaging two bonds between a protector group and a drug, in the case of drug delivery systems, after a stimuli.The cascade of reactions allows to control the release of the drug.

Searching for drugs for Chagas disease, leishmaniasis and schistosomiasis: a review.

Chagas disease, leishmaniasis and schistosomiasis are neglected diseases (NDs) and are a considerable global challenge. Despite the huge number of people infected, NDs do not create interest from pharmaceutical companies because the associated revenue is generally low. Most of the research on these diseases has been conducted in academic institutions.
