A new alleged monastrol-H2S releasing hybrid, named MADTOH, was designed based on the structure of monastrol (M) and 5-(4-hydroxyphenyl)-3H-1,2-dithiole-3-thione (ADTOH) and synthesized in 7.8% overall yield. MADTOH was shown to be an H2S donor under physiological conditions. In addition, the hybrid causes a decrease in global calcium transient in cardiomyocytes similar to nifedipine (NIFE), taken as a positive control. Whole-cell voltage-clamp showed that MADTOH decreases L-type Ca2+ current in isolated ventricular cardiomyocytes.

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.
Convenient method for the synthesis of 5-(4-methoxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OMe) and 5-(4-hydroxyphenyl)-3H-1,2-dithiol-3-thione (ADT-OH) using microwave irradiation

A convenient method is described for the rapid synthesis of 5-(4-methoxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OMe) from anethole and elemental sulfur using microwave irradiation. Various reaction conditions were applied to reduce the reaction time from several hours to 10?min, resulting in an improvement in yield and overcoming the undesired by-product formation associated with conventional methods. 5-(4-Hydroxyphenyl)-3H-1,2-dithiol-3-thione (ADT-OH) was obtained by the deprotection of ADT-OMe using pyridine hydrochloride under microwave irradiation.

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.
Gallic acid hydrogen sulfide derivative and preparation method and medical application thereof

, (2021/03/31)
The invention discloses a gallic acid hydrogen sulfide derivative and a preparation method and medical application thereof. The general formula of the gallic acid hydrogen sulfide derivative is A-Y-X,and A is gallic acid; Y is -C (O) O-, -C (O) NH-, -C (O) OC (O)-, -C (O) NHCH2 C (O)- or is absent, and when Y is absent, the compound is A-X; X is a moiety capable of releasing hydrogen sulfide alone or in combination with A. Compared with gallic acid and existing classic non-steroidal anti-inflammatory drugs, the gallic acid hydrogen sulfide derivative has the advantages that the anti-inflammatory activity is equivalent or enhanced, the side effects of gastrointestinal tracts and cardiovascular diseases are weakened, and the gallic acid hydrogen sulfide derivative has high anti-tumor activity and good cardiovascular and neuroprotective effects.
