Abstract
Background & Objective: Fungi are responsible for producing infections in humans. While all humans are susceptible to these disorders, immunocompromised people are the most at risk. Although it appears that we have many antifungal drugs in clinical use, unfortunately, most antifungal drugs currently in use have serious limitations or some drawbacks in pharmacokinetic aspects such as they do not possess an adequate solubility. As complement, fungi have developed a significant resistance against them because of their indiscriminate and even irrational use in some cases. Considering such situation, there is an urgent need to develop new and more effective antifungal drugs.
Discussion: For such reason, in recent years there has been an incredible increase in the number of studies looking for new compounds with antifungal effects; in particular new structures obtained from natural products. While a large number of compounds with antifungal activities (some of them with novel structures) have been reported, very few have managed to be used therapeutically. In this review article, we have identified and discussed the main reasons for the poor results that have been obtained so far in order to find new antifungal drugs. Also, new strategies which could be under way to improve the search for new antifungal agents for therapeutic use are discussed here, remarking their scope and limitations.
Keywords: Antimicrobial, natural products, antifungal, target-based screening, new drugs, new strategies.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
