In this study, we combined two enemin-type diterpenoid derivatives with two well-established hydrogen sulfide moieties via ester or different anhydride linkers, to search apoptosis inducing drug candidate capable of hydrogen sulfide generating. Therefore,

This work deals with the design, synthesis, and evaluation of the cardioprotective properties of a number of novel hybrid compounds combining the adenine nucleus with a suitable H2S slow-releasing moiety, coupled via a stable ether bond. The H2S release rate of the hybrids and their ability to increase cGMP were estimated in vitro. The most promising derivatives 4 and 11, both containing 4-hydroxythiobenzamide moiety as H2S donor, were selected for further in vivo evaluation. Their ability to release H2S in vivo was recorded using a new fully validated UPLC-DAD method. Both compounds reduced significantly the infarct size when administered at the end of sustained ischemia. Mechanistic studies showed that they conferred enhanced cardioprotection compared to adenine or 4-hydroxythiobenzamide. They activate the PKG/PLN pathway in the ischemic myocardium, suggesting that the combination of both pharmacophores results in synergistic cardioprotective activity through the combination of both molecular pathways that trigger cardioprotection.

The current pharmacological Chagas disease treatments, using Nifurtimox or Benznidazole, show limited therapeutic results and are associated with potential side effects, like mutagenicity. Using random screening we have identified new chemotypes that were able to inhibit relevant targets of the Trypanosoma cruzi. We found 3H-[1,2]dithioles with the ability to inhibit Trypanosoma cruzi triosephosphate isomerase (TcTIM). Herein, we studied the structural modifications of this chemotype to analyze the influence of volume, lipophilicity and electronic properties in the anti-T. cruzi activity. Their selectivity to parasites vs. mammalian cells was also examined. To get insights into a possible mechanism of action, the inhibition of the enzymatic activity of TcTIM and cruzipain, using the isolated enzymes, and the inhibition of membrane sterol biosynthesis and excreted metabolites, using the whole parasite, were achieved. We found that this structural framework is interesting for the generation of innovative drugs for the treatment of Chagas disease.
